modifying a function If statement

[acctman]

Hi I need help adding $inputUri to the function checkURL($string)

Hi can someone help me with this.

I have a inputbox that displays a default text "Input ID Here...". I need to take $inputUri and check it against function checkUrl($string) to see if its still there. If the text hasn't been cleared then display the addError message

 

public function checkUrl($string)
{
	$inputUri = 'Input ID Here...';

	if(empty($string) || preg_match("#^([A-Z0-9][A-Z0-9_ -]*(?:.[A-Z0-9][A-Z0-9_ -]*)+):?(d+)?/?#i", $string)))
	{
		return true;
	}
	else
	{
		if( isset($this) )
		{
			$this->addError("Error: Input Your ID");
		}
		return false;
	}
}
