I am using the following as the html input:
<input type="file" name="files[]" multiple="multiple" accept="image/*">
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:
$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 => $name) {
if ($_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] > $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
}
}
}
}
}
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?
