    <p>I am using the following as the html input:</p> <pre><code>&lt;input type="file" name="files[]" multiple="multiple" accept="image/*"&gt; </code></pre> <p>then this to upload multiple instances of the above input and attempt to compress by changing the image quality after each file is checked for errors:</p> <pre><code>$valid_formats = array("jpg", "png", "gif", "zip", "bmp"); $max_file_size = 1024*300; //300 kb $path = "uploads/"; // Upload directory $count = 0; if(isset($_POST) and $_SERVER['REQUEST_METHOD'] == "POST"){ // Loop $_FILES to execute all files foreach ($_FILES['files']['name'] as $f =&gt; $name) { if ($_FILES['files']['error'][$f] == 4) { // Compress the image files function compress_image($source_url, $destination_url, $quality) { $info = getimagesize($source_url); if ($info['mime'] == 'image/jpeg') $image = imagecreatefromjpeg($source_url); elseif ($info['mime'] == 'image/gif') $image = imagecreatefromgif($source_url); elseif ($info['mime'] == 'image/png') $image = imagecreatefrompng($source_url); // save file imagejpeg($image, $destination_url, $quality); // return destination file return $destination_url; } compress_image($_FILES['files']['name'], NULL, 90); continue; // Skip file if any error found } if ($_FILES['files']['error'][$f] == 0) { if ($_FILES['files']['size'][$f] &gt; $max_file_size) { $message[] = "$name is too large!."; continue; // Skip large files } elseif( ! in_array(pathinfo($name, PATHINFO_EXTENSION), $valid_formats) ){ $message[] = "$name is not a valid format"; continue; // Skip invalid file formats } else{ // No error found! Move uploaded files if(move_uploaded_file($_FILES["files"]["tmp_name"][$f], $path.$name)) { $count++; // Number of successfully uploaded files } } } } } </code></pre> <p>The files are uploaded just fine, however the compression doesn't take place. How can I compress the image filesize upon upload or each file?</p>

    1. COUse `var_dump` on every steps of code execution to verify if : `is_dir` : The destination of compressed files and add a condition like `($errors) ? exit("is an error in the file $destination_url")` in place of `continue`....

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
