Set Max Size in CodeIgniter File Upload - php

Question

I've used this private function to file upload in CodeIgniter Project. I've never set max_size in this function. Here, how to set max_size in this private function?
private function do_upload($value){
$type = explode('.', $_FILES[$value]["name"]);
$type = $type[count($type)-1];
$url = "./assets/uploads/products/".uniqid(rand()).'.'.$type;
if(in_array($type, array("jpg","jpeg","gif","png")))
if(is_uploaded_file($_FILES[$value]["tmp_name"]))
if(move_uploaded_file($_FILES[$value]["tmp_name"], $url))
return $url;
return "";
}

Answer 1

just simply do this.
if($_FILES["my_file_name"]['size'] > 1900000){ //set my_file_name to yours <input type="file" name="my_file_name">
echo "file is too large";
}else{
echo "file meets the minimum size";
}
if you want to set bigger upload size to your system, you need to go to php.ini file and change this.
upload_max_filesize = 2M; //change this to your desired size.
hope that helps.

Answer 2

You can get size of that file by $_FILES['uploaded_file']['size'],
for example:
$maxsize=2097152;
if(($_FILES['uploaded_file']['size'] >= $maxsize)) {
$errors[] = 'File too large. File must be less than 2 megabytes.';
}

Answer 3

you can create a php.ini file at your websites base folder
and add following (2M = 2 megabyte you can add your desired size )
upload_max_filesize = 2M;
on it

AS recommend: https://codeigniter.com/userguide3/libraries/file_uploading.html
2MB (or 2048 KB) So that:
$config['max_size'] = 1024 * 10; // <= 10Mb;
