  1. I am trying out a new script that lets me resize an image before uploading. It is based on this script. http://www.w3bees.com/2013/03/resize-image-while-upload-using-php.html Basically what happens is, it resizes and makes 3 thumbnails and puts them in their relative folder. That works. The part that's giving me the problem is when inserting it into the database. Error says the "image_path" cannot be null. Since it's creating an array of 3 different thumbnails, should I create 2 more fields in the database tabel to account for that? If so, how would I insert the 3 different thumbnail paths into the query? What would it look like? Below is my code. <?php $db_userid = intval($row['user_id']); $get_item_id = intval($row['item_id']); // settings $max_file_size = 5242880; // 5mb $valid_exts = array('jpeg', 'jpg', 'png', 'gif'); // thumbnail sizes $sizes = array(100 => 100, 150 => 150, 250 => 250); // dir paths $target_dir = 'images/'.$db_userid.'/items/'.$get_item_id.'/'; if ($_SERVER['REQUEST_METHOD'] == 'POST' AND isset($_FILES['image'])) { if(!empty($_FILES['image']['name'])) { if($_FILES['image']['size'] < $max_file_size ){ // get file extension $ext = strtolower(pathinfo($_FILES['image']['name'], PATHINFO_EXTENSION)); if(in_array($ext, $valid_exts)) { function resize($width, $height){ global $db_userid; global $get_item_id; /* Get original image x y*/ list($w, $h) = getimagesize($_FILES['image']['tmp_name']); /* calculate new image size with ratio */ $ratio = max($width/$w, $height/$h); $h = ceil($height / $ratio); $x = ($w - $width / $ratio) / 2; $w = ceil($width / $ratio); /* new file name */ $path = 'images/'.$db_userid.'/items/'.$get_item_id.'/'.$width.'x'.$height.'_'.$_FILES['image']['name']; /* read binary data from image file */ $imgString = file_get_contents($_FILES['image']['tmp_name']); /* create image from string */ $image = imagecreatefromstring($imgString); $tmp = imagecreatetruecolor($width, $height); imagecopyresampled($tmp, $image, 0, 0, $x, 0, $width, $height, $w, $h); /* Save image */ switch ($_FILES['image']['type']) { case 'image/jpeg': imagejpeg($tmp, $path, 100); break; case 'image/png': imagepng($tmp, $path, 0); break; case 'image/gif': imagegif($tmp, $path); break; default: exit; break; } return $path; /* cleanup memory */ imagedestroy($image); imagedestroy($tmp); } /* resize image */ foreach($sizes as $w => $h) { if(!is_dir($target_dir)){ mkdir($target_dir, 0775, true); } $files[] = resize($w, $h); } $insert_image = $db->prepare("INSERT INTO images(user_id, item_id, image_path, date_added) VALUES(:user_id, :item_id, :image_path, :date_added)"); $insert_image->bindParam(':user_id', $db_userid); $insert_image->bindParam(':item_id', $get_item_id); $insert_image->bindParam(':image_path', $path); $insert_image->bindParam(':date_added', $item_date_added); if(!$insert_image->execute()) { $errors[] = 'There was a problem uploading the image!'; } else { if(empty($errors)) { $db->commit(); $success = 'Your item has been saved.'; } else { $db->rollBack(); } } } else { $errors[] = 'Unsupported file'; } } else{ $errors[] = 'Please upload image smaller than 5mb'; } } else { $errors[] = 'An image is required!'; } }
