I have a form on the page. It has too many things like checkboxes and text fields and dropdowns. But when I don't select one of the checkboxes, the PHP page where i catch the form shows me an error.
Example:
The HTML Code:
Checkbox 1<input type="checkbox" name="check1" value="on" />
Checkbox 2<input type="checkbox" name="check2" value="on" />
The PHP Code:
$check1 = $_GET['check1'];
$check2 = $_GET['check2'];
It works fine if both the items are selected and sent in the URL:
localhost/project/checkbox.php?check1=on&check2=on
But when i deselect 1 of them, suppose check2, then the URL is like this:
localhost/project/checkbox.php?check1=on
and it shows me an error - that $check2 is an undefined index.
But I don't want it to show the error if the checkbox is not being selected. I also tried an if statement to check if i'm getting it in the URL but it didn't work.
Is there a way to first check weather the data is being passed in the URL or not? As I don't get the error. Actually the error is not the main thing, as I'm getting right results and I know I can switch off error reporting in php.ini, but thats not what I want to do. I want it to first check if data is coming in?
Thanks...
if (isset($_GET['check2']) && !empty($_GET['check2']) will do the check if check2 GET parameter is present and is not empty.
