SkyRanger Posted June 10, 2012 Share Posted June 10, 2012 Hey all, Ok, here is what I need to do, I already have it to create a thumb, but I also need to condense the uploaded image down 50%. Anybody have any idea, this is what I have so far: if(isset($_POST['submit'])) { $path_thumbs = "thumbs/"; $path_big = "images/"; $img_thumb_width = 100; $extlimit = "yes"; //Limit allowed extensions? (no for all extensions allowed) $limitedext = array(".gif",".jpg",".png",".jpeg",".bmp"); $file_type = $_FILES['vImage']['type']; $file_name = $_FILES['vImage']['name']; $file_size = $_FILES['vImage']['size']; $file_tmp = $_FILES['vImage']['tmp_name']; if(!is_uploaded_file($file_tmp)){ echo "Error: Please select a file to upload!. <br>--<a href=\"$_SERVER[php_SELF]\">back</a>"; exit(); //exit the script and don't process the rest of it! } //check the file's extension $ext = strrchr($file_name,'.'); $ext = strtolower($ext); if (($extlimit == "yes") && (!in_array($ext,$limitedext))) { echo "Wrong file extension. <br>--<a href=\"$_SERVER[php_SELF]\">back</a>"; exit(); } //so, whats the file's extension? $getExt = explode ('.', $file_name); $file_ext = $getExt[count($getExt)-1]; $rand_name = $file_name; //the new width variable $ThumbWidth = $img_thumb_width; ////////////////////////// // CREATE THE THUMBNAIL // ////////////////////////// //keep image type if($file_size){ if($file_type == "image/pjpeg" || $file_type == "image/jpeg"){ $new_img = imagecreatefromjpeg($file_tmp); }elseif($file_type == "image/x-png" || $file_type == "image/png"){ $new_img = imagecreatefrompng($file_tmp); }elseif($file_type == "image/gif"){ $new_img = imagecreatefromgif($file_tmp); } //list the width and height and keep the height ratio. list($width, $height) = getimagesize($file_tmp); //calculate the image ratio $imgratio=$width/$height; if ($imgratio>1){ $newwidth = $ThumbWidth; $newheight = $ThumbWidth/$imgratio; }else{ $newheight = $ThumbWidth; $newwidth = $ThumbWidth*$imgratio; } //function for resize image. if (function_exists(imagecreatetruecolor)){ $resized_img = imagecreatetruecolor($newwidth,$newheight); }else{ die("Error: Please make sure you have GD library ver 2+"); } //the resizing is going on here! imagecopyresized($resized_img, $new_img, 0, 0, 0, 0, $newwidth, $newheight, $width, $height); //finally, save the image ImageJpeg ($resized_img,"$path_thumbs/ies_thumb-$cid-$rand_name"); ImageDestroy ($resized_img); ImageDestroy ($new_img); } move_uploaded_file ($file_tmp, "$path_big/ies-$cid-$rand_name"); I am probably looking at it right now and not even seeing it.

SkyRanger Posted June 10, 2012 Author Share Posted June 10, 2012 Sorry, the problem I am having is taking the original file that is being uploaded and reduce the size by 50%. I can do it with the thumb, but not sure if I can still do it with the original.

Pikachu2000 Posted June 10, 2012 Share Posted June 10, 2012 OK, and what part of that is giving problems? Is there a specific error or something that's failing? Link to comment https://forums.phpfreaks.com/topic/263929-resize-image/#findComment-1352565 Share on other sites More sharing options...
SkyRanger Posted June 10, 2012 Author Share Posted June 10, 2012 the problem I am running into is having the same image resize twice, not sure how to exactly do that I was thinking of using imagecreatefrom but is there a simpler way of doing this instead of making one for each type of image. ie jpg png gif etc... with the code I am currently using. So what I am trying to figure out what do is: upload image.ext resize orig image.ext to 60% then create thumbimage.ext to 100px x 100px all in the same code Link to comment https://forums.phpfreaks.com/topic/263929-resize-image/#findComment-1352570 Share on other sites More sharing options...
