Hello, everyone , I'm here again , because wordpress The uploaded file displays the original file name , We use a simple code to automatically rename the uploaded file

First open the theme editor , Then double click. functions.php file , Finally, copy the code to the end of the file , The graphic tutorial and code are shown below

function git_upload_filter($file) {
	$time = date("Y-m-d ");
	$file['name'] = $time . "" . mt_rand(1, 100) . "." . pathinfo($file['name'], PATHINFO_EXTENSION);
	return $file;
}
add_filter('wp_handle_upload_prefilter', 'git_upload_filter');
