simple counter php




simple counter php


Make a folder named as "digits" in your web root in side the digit folder make another folder named as "1". Then you have to design images for numbers(0-9) by using image processing software as follows.


Name above images as 1,gif,2gif...............9.gif and incert into folder "1 " you created.Next you have to make empty text file called hits where visitors number of hits are storing.

Create below php file and run you can see the count of visitors hit.

<?PHP

$counterstyle = "images";  
$imagetype = "1";          

$hitslog = "hits.txt";    
$imagefolder = "digits";   

$hits = file($hitslog);
$hits = $hits[0] + 1;


$fp = fopen($hitslog, "w");
fwrite($fp, $hits);


if ($counterstyle == "text") { print $hits; }


if ($counterstyle == "images") {
 $digit = strval($hits);
 for ($i = 0; $i < strlen($hits); $i++) {
print "<img src=\"$imagefolder/$imagetype/$digit[$i].gif\">";
                }
        }

Users online php

Users online php

You have created my_database in your previous lessens.Now you have to create table called "useronline" in your my_database using following fields.

CREATE TABLE `useronline` (
  `id` int(10) NOT NULL auto_increment,
  `ip` varchar(15) NOT NULL default '',
  `timestamp` varchar(15) NOT NULL default '',
  PRIMARY KEY (`id`),
  UNIQUE KEY `id`(`id`)
) TYPE=MyISAM COMMENT='' AUTO_INCREMENT=1 ;

This page shows the number of users online

 <?php
 include_once ("usersOnline.php");
$visitors_online = new usersOnline();

if (count($visitors_online->error) == 0) {

    if ($visitors_online->count_users() == 1) {
        echo "<table bgcolor=#515fb0><tr bgcolor=#ffffff><td>There is " . $visitors_online->count_users() . " visitor online</td></tr></table>";
    }
    else {
        echo "<table bgcolor=#515fb0><tr bgcolor=#ffffff><td>There are " . $visitors_online->count_users() . " visitors online</td></tr></table>";
    }
}
else {
    echo "<b>Users online class errors:</b><br /><ul>\r\n";
    for ($i = 0; $i < count($visitors_online->error); $i ++ ) {
        echo "<table bgcolor=#515fb0><tr bgcolor=#ffffff><td>" . $visitors_online->error[$i] . "visitor online</td></tr></table>";
    }
}
?>

Bellow shows you usersOnline.php which connect with your data base and insert the user details.

<?php
$host = "localhost";
$user = "root";
$pass = "";
$db = "my_database";
$conn = mysql_connect("$host","$user","$pass") or die ("Unable to connect to database.");
mysql_select_db("$db", $conn);
class usersOnline {

    var $timeout = 600;
    var $count = 0;
    var $error;
    var $i = 0;
   
    function usersOnline () {
        $this->timestamp = time();
        $this->ip = $this->ipCheck();
        $this->new_user();
        $this->delete_user();
        $this->count_users();
    }
   
    function ipCheck() {
   
        if (getenv('HTTP_CLIENT_IP')) {
            $ip = getenv('HTTP_CLIENT_IP');
        }
        elseif (getenv('HTTP_X_FORWARDED_FOR')) {
            $ip = getenv('HTTP_X_FORWARDED_FOR');
        }
        elseif (getenv('HTTP_X_FORWARDED')) {
            $ip = getenv('HTTP_X_FORWARDED');
        }
        elseif (getenv('HTTP_FORWARDED_FOR')) {
            $ip = getenv('HTTP_FORWARDED_FOR');
        }
        elseif (getenv('HTTP_FORWARDED')) {
            $ip = getenv('HTTP_FORWARDED');
        }
        else {
            $ip = $_SERVER['REMOTE_ADDR'];
        }
        return $ip;
    }
   
    function new_user() {
        $insert = mysql_query ("INSERT INTO useronline(timestamp, ip) VALUES ('$this->timestamp', '$this->ip')");
        if (!$insert) {
            $this->error[$this->i] = "Unable to record new visitor\r\n";           
            $this->i ++;
        }
    }
   
    function delete_user() {
        $delete = mysql_query ("DELETE FROM useronline WHERE timestamp < ($this->timestamp - $this->timeout)");
        if (!$delete) {
            $this->error[$this->i] = "Unable to delete visitors";
            $this->i ++;
        }
    }
   
    function count_users() {
        if (count($this->error) == 0) {
            $count = mysql_num_rows ( mysql_query("SELECT DISTINCT ip FROM useronline"));
            return $count;
        }
    }

}

Get Visitors IP Address PHP

Get Visitors IP Address PHP

 web statistic is very important when you start  your own site.web statistics mainly consist of page views today,yesterday,last month &all history etc.in addition to those some applications have IP addresses of viewers display.In this post I show you how to collect Ip address of your page viewers and store in a text file.
                                           First you have to make empty  text file called "visitor.txt" in your web root. where store IP Addresses of visitors.
           Following PHP File track the visitors IP address and store in above text file.
<?php
$counter = "visitor.txt";
$today = getdate();
$month = $today[month];
$mday = $today[mday];
$year = $today[year];
$current_date = $mday . $month . $year;
$fp = fopen($counter, "a");
$line = $REMOTE_ADDR . "|" . $mday . $month . $year . "\n";
$size = strlen($line);
fputs($fp, $line, $size);
fclose($fp);
echo "IP Address: " . $_SERVER['REMOTE_ADDR'] . "<br>"; // Display IP address
echo "Referrer: " . $_SERVER['HTTP_REFERER'] . "<br>"; // Display the referrer
echo "Browser: " . $_SERVER['HTTP_USER_AGENT'] . ""; // Display browser type

Login System php

Login System php

Login system basically consist of Registration Form,Login form and Login out links, By looking at the sites which have logging systems you may view basically above files only.but behind those viewable files there are some files hidden and do very important role in logging systems I have created fallowing files to make this system work properly and keeping security to avoid unauthorized person access.
  1. register.php- contains registration form.
  2. register-check.php- validates the above form and checks with database the user existence  and conveys correctly filed form data into the MySql table.
  3. dbcon.php- Connects with your database "my_database".
  4. registered.php- inform you have registered successfully and link to login form. 
  5. login_form.pp-collect your login details. 
  6. check_login- check login details are correct or not If correct direct to member area and If not direct to login_ fail.php. 
  7. member-area.php- link to profile area and logout.
  8. login_failed-inform you your login details are wrong.
  9. logout.php- you can logout.
  10. authorisation.php- check  member id is present or direct to access-denied.php
  11. access-denied-access is not allowed who are going to type URL of member-area.php.
dbcon.php
    Create following table in your data base called "my_database".

     CREATE TABLE IF NOT EXISTS `members` (
      `member_id` int(11) NOT NULL AUTO_INCREMENT,
      `firstname` varchar(100) NOT NULL,
      `lastname` varchar(100) NOT NULL,
      `login` varchar(100) NOT NULL,

    different types of input php



    Different types of input php

    In HTML Form You may have seen different types of input fields like text fields,text areas,check boxes,options and radios etc.This post is to show you how to create above fields in HTML and how post the details of forms through a PHP file in to a MySql database.
                     By now you may have created the data base called "my_database" which we have used for our previous lessens. create table called "persanal_data" in your database using following fields and data type indicated.

    CREATE TABLE IF NOT EXISTS `persanal_data` (
      `id` int(50) NOT NULL AUTO_INCREMENT,
      `Fname` varchar(50) NOT NULL,
      `Lname` varchar(50) NOT NULL,
      `gender` varchar(50) NOT NULL,
      `level` varchar(50) NOT NULL,
      `details` longtext NOT NULL,
      `pet` varchar(50) NOT NULL,
      `drink` varchar(50) NOT NULL,
      PRIMARY KEY (`id`)
    ) ENGINE=MyISAM  DEFAULT CHARSET=latin1 AUTO_INCREMENT=1;

    Then I have created HTML file including different types of filed as follows.

       
    First Name:-
    Last Name:-
    Gender:-Male:-
    Female:-
    Please Select your Level of Education:-Primery:-
    Secondary:-
    University:-
    :
    Select a your favorite pet:-:
    Select type of drink:-:

    Then following php file should be created to send the collected data from the form to mysql.

    <?php
    $username="root";
    $password="";
    $database="my_database";
    $Fname = $_POST["Fname"];
    $Lname = $_POST["Lname"];
    $gender = $_POST["gender"];
    $level = $_POST["level"];
    $details = $_POST["details"];
    $pet = $_POST["pet"];
    $drink = $_POST["drink"];

    2.  deputy_director
    3.  Administrative_officer
    Director in an office can send files to above 3 officers or more.
    Following HTML file is used to upload files to above 3 folders.

                                  Upload To All











    multiple Files Upload
    Title
    Select file

    Codes for above file is as follows

    <html>
     <head>
     <title>UPload Multiple file</title>
    </head>
    <body>
    <center><h2>Upload To All </h2></center>
    <form action="upload4.php" method="post" enctype="multipart/form-data" name="form1" id="form1" > <tr><td>
    <table align="center">
    <tr><td colspan=2><hr></hr></td></tr>
    <tr> <td><strong>multiple Files Upload </strong></td> </tr>
    <tr><td>Title</td></tr>

    </form>
    <tr><td colspan=2><hr></hr></td></tr>
    </table>
    </body>
    </html>

    This uploaded files details are sent to a data base.Make 3 tables accountant, deputy_director and Administrative_officer in my_database which you have practiced in early lessens.Fields are stated in the below file for Administrative_officer table only.
     
    CREATE TABLE IF NOT EXISTS `Administrative_officer`
    ( `ID` int(11) NOT NULL AUTO_INCREMENT,

     `file` varchar(100) NOT NULL,
     `sender` varchar(45) NOT NULL,
    PRIMARY KEY (`ID`)
     ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

    upload4.php which carries uploaded 3 files to 3 folders is as follows
    <?php

    {
     if(copy($_FILES['ufile']['tmp_name'], $path1))
    {
     mysql_connect("localhost","root","") or die (mysql_error());
    mysql_select_db("my_database");
    $strSQL = "INSERT INTO accountant";
     $strSQL .="(date,time,Name,file,sender) VALUES ('$date','$time','".$_POST["txtName"]."','$new_file_name','".$_POST["sender"]."')"; mysql_query($strSQL); echo "<center>Uploaded To accountant</center> "; mysql_close();

    multiple file upload php


    Multiple File Upload into single folder

    Make Folder Named "upload" in your root directory Then you  have to make HTML form to submit uploaded files into upload folder in your root directory.Files I have created for this purpose are "mupload.html","mupload.php".

    Below shows you the file upload interface created from "mupload.html" pressing Add another link creates another upload field in to the interface.

    Multiple File Upload

    Add another
    Following codes generate the above file called "mupload.html".

    <html>
    <head>
     <title>multiple file upload </title>
    <script type="text/javascript">
    function add_file_field(){
    var container=document.getElementById('file_container');
    var file_field=document.createElement('input');
    file_field.name='images[]';
    file_field.type='file';
    container.appendChild(file_field);
     var br_field=document.createElement('br');
    container.appendChild(br_field);
    }
    </script>
    </head>
    <body>
     <form action="mupload.php" method="post" enctype="multipart/form-data" name="mutiple_file_upload_form" id="mutiple_file_upload_form">
     <h3>Multiple File Upload </h3>
    <div id="file_container"> <input name="images[]" type="file" /> <br /> </div>
    <a href="javascript:void(0);" onClick="add_file_field();">Add another</a><br />
    <input type="submit" name="Submit" value="Submit" />
    </form>
    </body>
     </html>

    Below shows you the"mupload.php"  file which carries the uploaded file into folder upload in your root directory.

    <?php
     if (isset($_POST['Submit'])) {
     $number_of_file_fields = 0;
     $number_of_uploaded_files = 0;
    $number_of_moved_files = 0;
    $uploaded_files = array();
    $upload_directory = dirname(__file__) . '/upload/';
     for ($i = 0; $i < count($_FILES['images']['name']); $i++) {
     $number_of_file_fields++;
     if ($_FILES['images']['name'][$i] != '') {
     $number_of_uploaded_files++;
     $uploaded_files[] = $_FILES['images']['name'][$i];
     if (move_uploaded_file($_FILES['images']['tmp_name'][$i], $upload_directory . $_FILES['images']['name'][$i])) {
    $number_of_moved_files++;
     }
     }
     }
    echo "Number of File fields created $number_of_file_fields.<br/> ";
     echo "Number of files submitted $number_of_uploaded_files . <br/>";
    echo "Number of successfully moved files $number_of_moved_files . <br/>";
    echo "File Names are <br/>" . implode(',', $uploaded_files);
    }
     ?>

    Single file upload php

    Before writing scripts for file upload make a Folder named "science" in your htdocs  or www (web root) then below contains a file in html format in which creates uploading interface and posting the uploaded file into php file called "upload.php". 
    html interface looks as below



    Select a file to upload
    Science:


     
    Fallowing Codes creates the above file upload interface.

    <html>
    <head>
    <script type="text/javascript" language="JavaScript"><!--
    function ExtensionsOkay() {
    var extension = new Array();
    var fieldvalue = document.Myform.file.value;
    extension[0] = ".doc";
    extension[1] = ".docx";
    extension[2] = ".jpg";
    extension[3] = ".jpeg";
    extension[4] = ".pdf";
    extension[5] = ".xls";
    var thisext = fieldvalue.substr(fieldvalue.lastIndexOf('.'));
     for(var i = 0; i < extension.length; i++) {
     if(thisext == extension[i]) { return true; }
     }
     alert("Your upload form contains an unapproved file name."); return false;
    }
    //--></script>
    </head>
    <body>
    <center> <br><br><br> Select a file to upload<br><br>
    <table >
    <tr>
    <td> <form name= "Myform" enctype="multipart/form-data" action="upload.php" method="POST" onsubmit="return ExtensionsOkay();"/>
     <input type="hidden" /> Science:</td><td> <input name="file" type="file" /></td><td> <input type="submit" value="Upload File" /> </form></td>
    </tr>
    </table>
    </center>
    </body>
    </html>

    upload.php is shown below.

    <html>
     <body>
    <?php
    $target_path = "science/";
     $target_path = $target_path . basename( $_FILES['file']['name']);
     if(move_uploaded_file($_FILES['file']['tmp_name'], $target_path)) {
    echo "The file ". basename( $_FILES['file']['name']). " has been uploaded";
    }
    else
    {
    echo "There was an error uploading the file, please try again!";

    view.php is shown below.

    <?PHP
     $folder = "science/";
    $handle = opendir($folder);
    while ($file = readdir($handle))

    php mysql delete

    PHP MySQL Delete 

    The DELETE statement is used to delete records in MySql tables.
    Delete Data In a Database Table
    Example:-
    Following is the biodata table we created in previous lesson.
    First Name Last Name Age
    Scarlett Johansson 25
    Clooney Anderson 25
    Kate Hudson Hudson 25

    We will delete the record with last name Anderson.
    The following codes deletes the records in the "biodata"  where LastName is Anderson.

    <?php
    $con = mysql_connect("localhost","root","");
    if (!$con)
      {
      die('Could not connect: ' . mysql_error());
      }

    mysql_select_db("my_database", $con);

    mysql_query("DELETE FROM biodata WHERE LastName='Anderson'");

    mysql_close($con);
    echo "delete 1 record";
    ?>

    Delete data using web interface (HTML PHP Files) 

    Re design the biodata view table with delete hyperlink like in following table. 

    Id First Name Last Name Age Delete
    1 Scarlett Johansson 25 delete
    2 Clooney Anderson 35 delete
    3 Kate Hudson 30 delete

    Codes for above modified table is as follows 

    <?php
     $host="localhost";
     $username="root";
     $password="";
     $db_name="my_database";
     $tbl_name="biodata";
    mysql_connect("$host", "$username", "$password")or die("cannot connect");   mysql_select_db("$db_name")or die("cannot select DB");
    $sql="SELECT * FROM $tbl_name";
    $result=mysql_query($sql);
    ?>
    <table bgcolor=#000000 align="center">
     <tr>
    <td align="center" bgcolor="#FFFFFF"><strong>Id</strong></td>
    <td align="center" bgcolor="#FFFFFF"><strong>First Name</strong></td>
     <td align="center" bgcolor="#FFFFFF"><strong>Last Name</strong></td>
    <td align="center" bgcolor="#FFFFFF"><strong>Age</strong></td>
    <td align="center" bgcolor="#FFFFFF"><strong>Delete</strong></td> </tr>
    <?php
    while($rows=mysql_fetch_array($result)){
    ?>
    <tr>
    <td bgcolor="#FFFFFF"><?php echo $rows['id']; ?></td>
    <td bgcolor="#FFFFFF"><?php echo $rows['FirstName']; ?></td>
    <td bgcolor="#FFFFFF"><?php echo $rows['LastName']; ?></td>
    <td bgcolor="#FFFFFF"><?php echo $rows['Age']; ?></td>
    <td bgcolor="#FFFFFF"><a href="delete_records.php?id=<?php echo $rows['id']; ?>">delete</a></td>
    </tr>
    <?php
     }
     mysql_close();
     ?>
    </table>

    "delete_records.php", The file which deletes data from the biodata table is bellow

    <?php
    $host="localhost";
    $username="root";
    $password="";
    $db_name="my_database";
    $tbl_name="biodata";
     mysql_connect("$host", "$username", "$password")or die("cannot connect"); mysql_select_db("$db_name")or die("cannot select DB");
     $id=$_GET['id'];
    $sql="DELETE FROM $tbl_name WHERE id='$id'";
    $result=mysql_query($sql);
    if($result)
    {
    echo "Deleted Successfully";
    }
    else
    {
    echo "ERROR";
    }
    mysql_close();
    ?>

    Delete Multiple Records in MySql Tables 

    Again we have to design the biodata table as follows with the facility of multiple delete interface.

    Php Multiple Records Delete






    ID





    First Name





    Last Name




    Age





    Delete Files
    1 Scarlett Johansson 25




    Yes
    2 Clooney Anderson 35




    Yes
    3 Kate Hudson 30




    Yes
    Select Check box and Press Submit To Delete files

    Look at bellow codes to create multiple delete php

    <?php
    $dbHost = 'localhost';
    $dbUser = 'root';
    $dbPass = '';
    $dbName = 'my_database';
    $dbConn = mysql_connect ($dbHost,$dbUser, $dbPass) or die ('MySQL connect failed. ' . mysql_error());
    mysql_select_db($dbName) or die('Cannot select database. ' . mysql_error());
    ?>
    <html>
     <head>
     <title></title>
     </head>
    <body>
     <h2><font color="#54164e"><center>Php Multiple Records Delete</font></center></h2>
    <table align="center" bgcolor="#9a7608" >
    <tr bgcolor="#ffffff">
     <th> <center> ID </center> </th> <th> <center> First Name </center> </th>
    <th> <center> Last Name</center> </th>
    <th> <center> Age </center> </th>
    <th> <center> Delete Files </center> </th> </tr>
    <?php
     if($_POST['btsubmit']=='Submit') {
     foreach($_POST as $k => $v){
    $$k = $v;
    }
     $to_del= $_POST['to_del'];
    if (("submit")&&($to_del != "")) {
     }
    foreach($to_del as $v){
     mysql_query("DELETE FROM biodata where id='$v'");
    }
     echo "<center><font color='white' size=5> records is been deleted.</font></center></br>";
    }
    ?>
    <?php $query = "SELECT * FROM biodata";
     $result = mysql_query($query);
     while ($row = mysql_fetch_assoc($result)){
     ?>
    <form name="form" method="post">
    <tr bgcolor="#ffffff">
    <td><?php echo $row["ID"];?></td>
    <td><?php echo $row["FirstName"];?></td>
    <td><?php echo $row["LastName"];?></td>
    <td><?php echo $row['Age'];?></td>
    <td> <center> <input type=checkbox name="to_del[]" value="<?php echo $row["id"];?>">Yes </center> </td>
    </tr>
    <?php
     }
    ?>
    <tr><th colspan=4 bgcolor="#ffffff">Select Check box and Press Submit To Delete files</th><td bgcolor="#ffffff"><input type="submit" value="Submit" name="btsubmit"></td>
    </tr>
    </table>
    </form>
    </body>
    </html>
