Deleting Images

MiniMonty · November 12, 2009

Hi all,

First the set up:

Each user has a numbered dir. Inside is a dir "images" and inside that a dir "thumbs".

Users upload images to their "images" dir.

A file path is recorded in the db.

Now the question...

I have a script that will display take all the images uploaded by any given user, make a thumbnail copy

of each one in "thumbs" then display the thumbnails in a table.

Each image has a checkbox beneath it. At the top of the page is a submit button "Delete"

It goes like this:

<?php
session_start(); 

 if(isset($_GET['id']) || isset($_POST['id']));

else if (isset($_SESSION['id'])) {


 $id = $_SESSION['id'];

} else {

   include_once "register.php";
   exit();
}
   
include_once "scripts/connect_to_mysql.php";
$deleteMsg= "Your image was successfully delted";
   
$id = $_SESSION['id'];
ob_start();

$dir = opendir( "members/$id/images" );
$pics = array();
while( $fname = readdir( $dir ) )
{
	if ( preg_match( "/[.]jpg$/", $fname ) )
		$pics []= $fname;
}
closedir( $dir );
foreach( $pics as $fname )
{
  $im = imagecreatefromjpeg( "members/$id/images/$fname" );
  $ox = imagesx( $im );
  $oy = imagesy( $im );

  $nx = 100;
  $ny = floor( $oy * ( 100 / $ox ) );

  $nm = imagecreatetruecolor( $nx, $ny );

  imagecopyresized( $nm, $im, 0, 0, 0, 0, $nx, $ny, $ox, $oy );	
  imagejpeg( $nm, "members/$id/images/thumbs/$fname" );
 }

 ?>
 <html>

 <style type="text/css">

     </style>
 </head>
 <body>
     <?php include_once "header_template3.php"; ?>
     <br>
     <br>
     <br>     
     <div align="left"><br>
     </div>
     <form name="form1" method="post" action="manage_images.php">
       <table width="80%"  border="0" align="center">
         <tr>
           <td><div align="center" class="Times19">Check the box for each image you want to permanently delete then click 
               <input type="submit" name="Submit" value="Delete">
           </div></td>
         </tr>
         <tr>
           <td> </td>
         </tr>
         <tr>
           <td>
             <table width="500" border="0" align="center" cellpadding="2" cellspacing="0" bordercolor="#FFFFFF">
               <tr>
                 <?php
 $index = 0;
 foreach( $pics as $fname ) {
 ?>
                 <td valign="middle" align="center"> <a href="../<?php echo( $fname ); ?>"><img src="<?php echo( $fname );?>" border="2" class="orangeText" /></a> <br>
				 <input type="checkbox" name="delete_pictures[]" value="$fname" /></td>
                 <?php
 $index += 1;
 if ( $index % 7 == 0 ) { echo( "</tr><tr>" ); }
 } 
 ?>
               </tr>
           </table></td>
         </tr>
       </table>
     </form>
     <br>
 <?php include_once "footer_template.php"; ?>
 </body>
 </html>
 <?php

 $html = ob_get_clean();
 $fh = fopen( "members/$id/images/thumbs/display.php", "w" );
 fwrite( $fh, $html );
 fclose( $fh );
 header("Location: members/$id/images/thumbs/display.php");

ob_end_flush();
?>

What I want to acheive is for users to check all the images they want to delete, click the button and presto !

Image deleted from "images", thumb deleted form "thumbs" and record deleted from the db.

I've tried quite a few ways but no joy so all and any help on this much appreciated.

Best wishes

Monty

Deleting filed is done by

unlink($Filepath);

If that doesn't work, put this before it

chmod($Filepath, '0777');
