Gem Posted November 1, 2010 Share Posted November 1, 2010 Hey guys. I'm using this script to handle file (picture) uploads at the moment, and it works fine. Problem is though, I need to changeit to a multiple upload form (with 10 uploads per submit) and I dont know how to do it. I think ... I need to change this "<input type="file" name="image" >" to an array ... and put a "for each" loop or something somewhere ... but I really don't know what I am doing. Can someone please help? Thanks Gem <?php include ("includes/dbconnect120-gem.php"); //define a maxim size for the uploaded images define ("MAX_SIZE","500"); // define the width and height for the thumbnail // note that theese dimmensions are considered the maximum dimmension and are not fixed, // because we have to keep the image ratio intact or it will be deformed define ("WIDTH","150"); define ("HEIGHT","100"); // this is the function that will create the thumbnail image from the uploaded image // the resize will be done considering the width and height defined, but without deforming the image function make_thumb($img_name,$filename,$new_w,$new_h) { //get image extension. $ext=getExtension($img_name); //creates the new image using the appropriate function from gd library if(!strcmp("jpg",$ext) || !strcmp("jpeg",$ext)) $src_img=imagecreatefromjpeg($img_name); if(!strcmp("png",$ext)) $src_img=imagecreatefrompng($img_name); //gets the dimmensions of the image $old_x=imageSX($src_img); $old_y=imageSY($src_img); // next we will calculate the new dimmensions for the thumbnail image // the next steps will be taken: // 1. calculate the ratio by dividing the old dimmensions with the new ones // 2. if the ratio for the width is higher, the width will remain the one define in WIDTH variable // and the height will be calculated so the image ratio will not change // 3. otherwise we will use the height ratio for the image // as a result, only one of the dimmensions will be from the fixed ones $ratio1=$old_x/$new_w; $ratio2=$old_y/$new_h; if($ratio1>$ratio2) { $thumb_w=$new_w; $thumb_h=$old_y/$ratio1; } else { $thumb_h=$new_h; $thumb_w=$old_x/$ratio2; } // we create a new image with the new dimmensions $dst_img=ImageCreateTrueColor($thumb_w,$thumb_h); // resize the big image to the new created one imagecopyresampled($dst_img,$src_img,0,0,0,0,$thumb_w,$thumb_h,$old_x,$old_y); // output the created image to the file.

rwwd Posted November 1, 2010 Share Posted November 1, 2010 You could just have a zip uploader, then once the zip has uploaded you can iterate through the files contained in that file; Or you can have ten separate file selector boxes, and just loop through each of those, so your logic wasn't far off!
