PHP - Sort Thumbnail Display.
Hi all
Let me start by saying I'm a noob - who is trying to sort (order) the displayed thumbnails from the script below. I've read the sort, explode, scandir and array manuals - but every attempt fails. I've been reading for days.. and still nothing. I got the script from the net.. While researching how to make this work, I found someone else using the same script needing help on your forums... (http://www.phpfreaks.com/forums/index.php/topic,299137.0.html) I've changed mine a little to work with the directories, and added Javascript for displaying the clicked thumb, in place. The entire thing works like a charm, and displays the generated thumbs and so on - its just that when it comes out on the page, it's in a random order like 2.jpg, 3.jpg, 1.jpg. (It always seems to display the first photo last.) I'd like it to display 1.jpg, 2.jpg, 3.jpg so they appear in order on the page. This way I can group black and white photos from color photos in the same category, or show photos in the order they happened on a vacation for instance. Thanks in advance for any insight! <?php $columns = 5; $thmb_width = 120; $thmb_height = 80; function resizeImage($originalImage,$toWidth,$toHeight){ list($width, $height) = getimagesize($originalImage); $xscale=$width/$toWidth; $yscale=$height/$toHeight; if ($yscale>$xscale){ $new_width = round($width * (1/$yscale)); $new_height = round($height * (1/$yscale)); } else { $new_width = round($width * (1/$xscale)); $new_height = round($height * (1/$xscale)); } $imageResized = imagecreatetruecolor($new_width, $new_height); $imageTmp = imagecreatefromjpeg ($originalImage); imagecopyresampled($imageResized, $imageTmp, 0, 0, 0, 0, $new_width, $new_height, $width, $height); return $imageResized; } function generateThumbnails(){ global $thmb_width,$thmb_height; if ($handle = opendir("/full/path/to/images/galleryname/")) { while ($file = readdir($handle)) { if (is_file($file)){ if (strpos($file,'_th.jpg')){ $isThumb = true; } else { $isThumb = false; } if (!$isThumb) { $dirName = substr($file,0,strpos($file,basename($file))); if (strlen($dirName) < 1) $dirName = '.'; $fileName = basename($file); $fileMain = substr($fileName,0,strrpos($fileName,'.')); $extName = substr($fileName,strrpos($fileName,'.'), strlen($fileName)-strrpos($fileName,'.')); if (($extName == '.jpg') || ($extName == '.jpeg')){ $thmbFile = $dirName.'/'.$fileMain.'_th.jpg'; if (!file_exists($thmbFile)){ imagejpeg(resizeImage($file,$thmb_width,$thmb_height) ,$thmbFile,80); }}}}}}} function getNormalImage($file){ $base = substr($file,0,strrpos($file,'_th.jpg')); if (file_exists($base.'.jpg')) return $base.'.jpg'; elseif (file_exists($base.'.jpeg')) return $base.'.jpeg'; else return ""; } function displayPhotos(){ global $columns; generateThumbnails(); $act = 0; $img_dir = 'images/galleryname/'; if ($handle = opendir($img_dir)) { while ($file = readdir($handle)) { if (strpos($file,'_th.jpg')){ ++$act; if ($act > $columns) { echo '<li><a onclick="return showPic(this)" href="'.getNormalImage($img_dir.$file).'"><img src="'.$img_dir.$file.'" alt="'.$file.'"/></a></li>'; }}}}} ?> <script type="text/javascript" language="javascript"> function showPic (whichpic) { if (document.getElementById) { document.getElementById('placeholder') .src = whichpic.href; if (whichpic.title) { document.getElementById('desc') .childNodes[0].nodeValue = whichpic.title; } else { document.getElementById('desc') .childNodes[0].nodeValue = whichpic.childNodes[0].nodeValue; } return false; } else { return true; } }</script> <div class="galthumbs"><ul> <?php displayPhotos(); ?> </ul></div> <div class="galmain"><img id="placeholder" src="images/galleryname/1.jpg" alt="" /></div><p id="desc"> </p> Similar TutorialsI have a classified ad program where I need to export ads (items).

Hi all, completely new at this and have got myself stuck! I am trying to display a thumbnail image by connecting to my database and retrieving the URL that points to the image. I know that the connection is working but I can't seem to get it to point to the image. Probably something really simple.

This is just for testing, I'll get round to sorting out security issues later. Your help will be greatly appreciated! Regards, Nortski. Is there any way to generate a small image of the 1st page of a pdf document without using a 3rd party like imagemagic. The site is hosted a register.com so I am thinking I am going to be limited to the basic php functions. I would be needing different picture sizes on different pages on my site but saving different sizes of a single pic is space consuming. I've heard that it's possible to automatically adjust the size of the picture and found a script that ought to make that possible. Unfortunately, it did not work for me.

Quote All it takes is replacing the "src" parameter in the <img> tag with the URL for the PHP script, including the parameters "src" which contains the path to the original image file, and "color" to select the color for the font. The script also supports a "width" parameter to specify the width of your thumbnail image. Using that script to display the above image as a thumbnail by setting the "src" attribute to "makeThumb.php?src=slides/slide1.jpg", we get the resulting image shown on the right. Can anyone please help me with this script or something similar? Thanks in advance. ^_^ Edit: The problem is that the image is not showing.

Hi, I was curious if there is anyway to create website screenshots on the fly via a php script. Thanks, dilbertone - the first dilbert on earth Hi! I'm looking for a script that can do the following: upload one or preferably fx. five image files(jpg) resizes them to a specific size if they exceeds that size. create a thumbnail No files above 100kb can be uploaded. uploaded and/or processed files must be renamed with a unique file name. Work with php5 I have searched the internet for a script like that, but I can't find one that matches my needs. Also, the code must include good comments and nott be to hard to understand. So as basic code as possible. I have a quick question about a script I wrote that searches all .jpg images in a directory (and it's sub-directories) and makes thumbnails of them.

Here is what I have: Code: [Select] <?php $idir = "../fleet/"; // Path To Images Directory if (isset ($_FILES['fupload'])){ //upload the image to tmp directory $url = $_FILES['fupload']['name']; // Set $url To Equal The Filename For Later Use if ($_FILES['fupload']['type'] == "image/jpg" || $_FILES['fupload']['type'] == "image/jpeg" || $_FILES['fupload']['type'] == "image/pjpeg") { $file_ext = strrchr($_FILES['fupload']['name'], '$account.'); // Get The File Extention In The Format Of , For Instance, .jpg, .gif or .php $copy = copy($_FILES['fupload']['tmp_name'], "$idir" . $_FILES['fupload']['name']); // Move Image From Temporary Location To Perm } } $fleetimage1 = mysql_real_escape_string("$idir" . $_FILES['fupload']['name']); //then insert sql code below... ?> Im trying to write an image upload script which checks various elements of the image and then saves it and and a thumbnail into a folder. At the moment I am getting a white screen which makes me think I have a syntax error so I have come here to find some fresh eyes to help me out. Can anyone see any reason why this wouldn't be working? Form Code: [Select] <form enctype='multipart/form-data' action='upload_image.php' method='POST'> <table class='uploads-form'> <tr> <td><input name='image' type='file' /><input type='hidden' name'MAX_FILE_SIZE' value='5000000' /></td> </tr> <tr> <td><input type='submit' name='upload_image' value='Upload' /></td> </tr> </table> </form> php <?php error_reporting(E_ALL); ini_set("display_errors", 1); $images_location = "project_files/"; $thumbs_location = "project_thumbs/"; $thumb_width = "100"; $maximum_size = "5000000"; //Auto Thumbnail Function function create_thumbnail($source,$destination, $thumb_width) { $size = getimagesize($source); $width = $size[0]; $height = $size[1]; $x = 0; $y = 0; if($width> $height) { $x = ceil(($width - $height) / 2 ); $width = $height; } elseif($height> $width) { $y = ceil(($height - $width) / 2); $height = $width; } $new_image = imagecreatetruecolor($thumb_width,$thumb_width) or die('Cannot initialize new GD image stream'); $extension = get_image_extension($source); if($extension=='jpg' || $extension=='jpeg') $image = imagecreatefromjpeg($source); if($extension=='gif') $image = imagecreatefromjpeg($source); if($extension=='png') $image = imagecreatefromjpeg($source); imagecopyresampled($new_image,$image,0,0,$x,$y,$thumb_width,$thumb_width,$width,$height); if($extension=='jpg' || $extension=='jpeg') imagejpeg($new_image,$destination); if($extension=='gif') $imagegif($new_image,$destination); if($extension=='png') imagepng($new_image,$destination); } //Get Extension Function function get_image_extension($name) { $name = strtolower($name); $i = strrpos($name,"."); if (!$i) { return ""; } $l = strlen($name) - $i; $extension = substr($name,$i+1,$l); return $extension; } //Random Name Function function random_name($length) { $characters = "abcdefghijklmnopqrstuvwxyz01234567890"; $name = ""; for ($i = 0; $i < $length; $i++) { $name .= $character[mt_rand(0, strlen($characters) - 1)]; } return "image-".$name; } //Check And Save Image if(isset($_POST['upload_image'])) { if($_FILES['image']['name'] == ""){ echo = "Please select the image you would like to upload by clicking browse"; } else{ $size=filesize($_FILES['image']['tap_name']); $filename = stripslashes($_FILES['image']['name']); $extension = get_image_extension($filename); if($size > $maximum_size) { echo = "Your file size exceeds the maximum file size!"; } else if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif")) { echo = "Only the following extensions are allowed.
