Generate a copy of image in different sizes
Submitted by yandine - 8 years ago
This script is for generating copies of uploaded images in different sizes. In my case I created a custom Library folder and then created a class FileUploader and add all functions that deals with any image uploads.
namespace App\Library ;
class FileUploader
{
public static function uploadImageWithCopies($path = null, $uploaded_file = null, $file_name = null, $custom_sizes = null)
{
try{
$imginfo_array = getimagesize($uploaded_file);
$mime_type = $imginfo_array['mime'];
if ($mime_type == "image/jpeg"){
$src = imagecreatefromjpeg($uploaded_file);
}else if($mime_type == "image/png"){
$src = imagecreatefrompng($uploaded_file);
}else if($mime_type == "image/gif"){
$src = imagecreatefromgif($uploaded_file);
}else{
throw new Exception("Invalid Image");
}
//1
$inc=0;
$newwidth =array();
$newheight =array();
$tmp =array();
$location =array();
foreach($custom_sizes as $cS){
list($width,$height) = getimagesize($uploaded_file);
$newwidth[$inc] = $cS['width'];
$newheight[$inc] = ($height/$width)*$newwidth[$inc];
$tmp[$inc] = imagecreatetruecolor($newwidth[$inc],$newheight[$inc]);
imagecopyresampled($tmp[$inc],$src,0,0,0,0,$newwidth[$inc],$newheight[$inc],$width,$height);
$location[$inc] = $path.$cS['prefixStr']. $file_name;
$inc++;
}
$inc=0;
foreach($custom_sizes as $cS){
if ($mime_type == "image/jpeg"){
if (imagejpeg($tmp[$inc],$location[$inc],100)){}else{throw new Exception("Invalid Image");}
}else if($mime_type == "image/png"){
if (imagepng($tmp[$inc],$location[$inc],9)){}else{throw new Exception("Invalid Image");}
}else if($mime_type == "image/gif"){
if (imagegif($tmp[$inc],$location[$inc],9)){}else{throw new Exception("Invalid Image");}
}else{
throw new Exception("Invalid Image");
}
$inc++;
}
$inc=0;
foreach($custom_sizes as $cS){
imagedestroy($tmp[$inc]);
$inc++;
}
}
catch(Exception $e){
return false;
}
}
}
