Add image size (width,height) validator

[jovicaj]

Hello
Is there an option to check image width and height?

[deba12]

I hacked up something like this bellow

public function validate_image_size($field, $input, $param = null) {
	if (!isset($input[$field])) {
		return;
	}
	if (is_array($input[$field]) && $input[$field]['error'] !== 4) {
		$size = explode(';', $param);
		$image_info = getimagesize($input[$field]['tmp_name']);
		if(($image_info[0] <= $size[0]) && $image_info[1] <= $size[1]) {
			return;
		}
		return array(
			'field' => $field,
			'value' => $input[$field],
			'rule' => __FUNCTION__,
			'param' => $param,
		);
	}
}

and validation rule:

	$this->validate->validation_rules(array(
		'file'		=> 'required_file|image_size,768;90'
	));

Is it not beter to make a new function for this with gump::add_validator?
because when you update your script the changes are gone.

GUMP::add_validator('image_size', function ($field, $input, $param){ if (!isset($input[$field])) { return; } if (is_array($input[$field]) && $input[$field]['error'] !== 4) { $size = explode(';', $param); $image_info = getimagesize($input[$field]['tmp_name']); if(($image_info[0] <= $size[0]) && $image_info[1] <= $size[1]) { return; } return [ 'field' => $field, 'value' => $input[$field], 'rule' => __FUNCTION__, 'param' => $param, ]; } });
