How can I add a custom validation for the url type in the advanced custom field.
I want to validate the input for the http:// or https://

Hi @mukesh.t,

You can use parse_url(...) PHP function in your acf/validate_value function.

add_filter('acf/validate_value/name=validate_this_image', 'my_acf_validate_value', 10, 4);

function my_acf_validate_value( $valid, $value, $field, $input ){
	
	if( !$valid ) {
		
		return $valid;
		
	}
	...	
	parse_url($value);

	if($url['scheme'] == 'https'){
	   // is https;
	}
	...	
	
}
