Hi, I am trying to upload and resize an image on my server but i am getting an out of memory error. My php limit is 64M so i dont see why it wont work. My Code: <?php case "jpg": $file = imagecreatetruecolor($width, $height); $new = imagecreatefromjpeg($this->file_tempname); for($i=0; $i<256; $i++) { imagecolorallocate($file, $i, $i, $i); } imagecopyresampled($file, $new, 0, 0, 0, 0, $width, $height, $this->file_width, $this->file_height); imagejpeg($file, $photo_dest, 60); imagedestroy($new); imagedestroy($file); break; ?> any ideas?

all thumbs are created during photo upload, lets say the system, needs to make 10 thumbs of each photo uploaded and 20 people are uploading at once wont the system just fold up?

Because if you have a larger image and you want to scale it down to say 64x64 then it slows the page down

Yes but i have like 10 different sized thumbs to create and space is a problem

Hi, I have a script on my site that creates thumbnails on the fly, my question is: will it affect server performance greatly doing thumbnails this way? I have quite a few different sizes to display that creating them all would be too much space used. Thanks in advance

Works like a charm, thanks

Is there any way to do this or am i doing it all wrong? I would need $_POST['date'] and $_POST['time'] to make one time stamp containing the correct date and time. Thanks

Hi, I am making a php image hosting script for my site and i need to get the image to display to the browser on select.. The code will not work and only prints the php file name to the browser???

<?php if(isset($_POST['file_option']) && $_POST['file_option'] == 'zip') { $files_array = $_POST['image_file']; // Move image foreach ($files_array as $f) { $r = sql_row("SELECT * FROM iv_uploads WHERE id = '".$f."'"); $filess = './uploads/' . $r['image_name']; $files = array($filess); } create_zip($files, $username . '_images.zip', false); header("Pragma: public"); header("Expires: 0"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Content-Type: application/force-download"); header("Content-type: application/octet-stream"); header("Content-Type: application/download"); header("Content-disposition: attachment; filename=". $username .

Hi, I am trying to zip up user files from a posted form, the form posts the file ids and then my script query's the database to get the file name. The only problem is that it only adds one file to the zip archive. Here is the code: <?php if(isset($_POST['file_option']) && $_POST['file_option'] == 'zip') { $files_array = $_POST['image_file']; // Move image foreach ($files_array as $f) { $r = sql_row("SELECT * FROM iv_uploads WHERE id = '".$f."'"); $filess = './uploads/' . $r['image_name']; $files = array($filess); create_zip($files, $username . '_images.zip', false); header("Pragma: public"); header("Expires: 0"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Content-Type: application/force-download"); header("Content-type: application/octet-stream"); header("Content-Type: application/download"); header("Content-disposition: attachment; filename=". $username . "_images.zip"); header("Content-Transfer-Encoding: binary"); header("Content-Length: ".filesize($username . "_images.zip")); readfile($username . "_images.zip"); } ?> any ideas?

fixed it! the form was 100% fine it was the following php code: $files_array = array($_POST['delete_file']); should be $files_array = $_POST['delete_file']; all fixed now thanks for your help.

<div class="right_side" id="right_side"> <form method="post" action="{$url->url_base}/myfiles" name="file_options"> <div class="file_options"> <select name="file_option"> <option value="" selected="selected">-- Selected Image Options --</option> <option value="delete">Delete image(s)</option> <option value="">-- Move Image To --</option> <option value="1">folder one</option> </select> <input type="submit" value="Go" /> <input type="button" value="Upload" /> <div style="margin-top:8px;"><strong>Select:</strong> <a href="javascript:;" onclick="javascript:selectToggle(true, 'file_options');">All</a>, <a href="javascript:;" onclick="javascript:selectToggle(false, 'file_options');">None</a></div> </div> {if $num_results == 0} <div align="center" style="margin-top:10px;"> <div class="info"> You currently have no uploaded images. </div> </div> {else} <style type="text/css">{literal} input.cb {position:absolute; margin-top:4px;} </style>{/literal} <div style="margin-top:10px;"> <table border="0" cellpadding="6" cellspacing="6"> <tbody> <tr> {foreach name=images item=row from=$results} <td> <div class="img" id="img_{$row.id}" style="text-align:center;margin:0 auto;"> <input type="checkbox" class="cb" name="delete[]" value="{$row.id}" /> <a href="{$url->url_base}/viewer/{$row.id}/{$row.image_name}"> <img src="./uploads/{$row.image_thumb}" alt="" class="image_thumb" id="{$row.id}" /> </a> </div> <div style="clear:both; text-align:left"></div> </td> {if $smarty.foreach.images.iteration mod $columns eq 0} </tr> {/if} {/foreach} </tr> </tbody> </table> </td> </tr> </table> </div> </form> {/if} </div>

this is my code so far and it wont work: <?php ## Delete multiple file ## if(isset($_POST['file_option']) && $_POST['file_option'] == 'delete') { // Get file path and file id $path = $setting['upload_path']; // Loop through data and delete files $files_array = array($_POST['delete']); foreach ($files_array as $files) { // Query database to get file info $query_file = @mysql_query("SELECT * FROM uploads WHERE id = '".$files."' AND upload_owner = '".$_SESSION['userid']."' LIMIT 1"); $file = @mysql_fetch_array($query_file); // Delete file from server @unlink($path.$file['image_name']); // Delete thumb from server @unlink($path.$file['image_thumb']); // Delete file from database @mysql_query("DELETE FROM uploads WHERE id = '".$files."' AND upload_owner = '".$_SESSION['userid']."' LIMIT 1"); // Redirect @header("Location:" . $url->url_base . '/myfiles'); } } ?> any ideas?

something like this? $arr = array(1, 2, 3, 4); foreach ($arr as &$value) { $value = $value * 2; }

I have fixed that part now, its the while im stuck on... does it go like this? while($_POST['delete']) { // do stuff here } steve

thanks for that, im currently trying to learn php thats why i need help. I have done what you said and when i use the print_r function i get this: Array ( [0] => on [1] => on [2] => on [3] => on [4] => on [5] => on ) how do i make it so i can delete my files from that? thanks

how would i do the looping? im quite new to php

is it the correct doc type? or maybe the encoding for the page is wrong?
