check to see if several variables have been set

[dazzclub]

Hi there,

 

I'm working on a questionnaire and I need to ensure that the users cant proceed to the next page without selecting/completing a field.

 

I need to check multiple variables as the path the user takes depends on the submitted questions.

 

So I tried to use

if(!isset($response_time_email || $effectivenes ){

but I keep getting stumped.

 

Here is the original code;

if(isset($_POST['submitted'])) {


$response_time_email = $_POST['response_time_email'];


//has radio been checked

if(!isset($response_time_email)){

		$fail =  "<div id=\"fail\"><p>You must select a field before you proceed to the next page</p></div> ";

}else{

	if(isset($response_time_email)) {

	//$confirm = 'yes '.$contact_us.'';
	header('Location:page3.php');

	}
}
}

 

Any help would be great, thank you.

if(!isset($response_time_email)){

That is always set in your context because the variable is set. It may be empty, but it's set. The check in the else case is stupid. It's either set or not. There's no need for the if statement inside the else.

Your right made sense, thank you.

 

Here is the updated code;

if(isset($_POST['submitted'])) {


$recommend = $_POST['recommend'];



//has radio been checked

if($recommend == '') {

		$fail =  "<div id=\"fail\"><p>You must select a field before you proceed to the next page</p></div> ";

}else{


	//$confirm = 'yes '.$contact_us.'';
	header('Location:page7.php');

	}
}

 

Thank you
