#53 - How do I get more debug output?

If you have access to php.ini, set the following:

Code:

error_reporting  =  E_ALL | E_STRICT
display_errors = On
display_startup_errors = On
ignore_repeated_errors = Off
ignore_repeated_source = Off

Failing that, you can use ini_set() to set some of the above (mostly error_reporting and display_errors are useful).

And no, that '|' should NOT be '&' on error_reporting. Otherwise you will only get strict errors. Bitwise operators do not work the same way as logical operators!

#54 - How do I tell if a form checkbox was NOT checked?

Pretend your checkbox is named "box". Creative, I know.
You may already know that if "box" is checked then $_POST["box"] has some value.
However if "box" is not checked, $_POST["box"] does not have a value. In fact, $_POST["box"] doesn't exist: you'll get an "Undefined index 'box'" warning.

The easiest thing to do with checkboxes is to use isset():

PHP Code:


		
			
<html><body>

<?php



if (isset($_POST["submit"])) {

    $was_checked = isset($_POST["box"]);



    if ($was_checked) {

        echo "<p>You checked the box.</p>";

    } else {

        echo "<p>You did not check the box.</p>";

    }

}



?>

<form action="<?=$_SERVER["REQUEST_NAME"]?>" method="post">

<p><input type="checkbox" name="box" /> Check this box

<input type="submit" name="submit" value="Submit" /></p>

</form>

</body></html>

Note: of course, if your form uses method=get then you should be using $_GET instead of $_POST. But the same rules apply to both of those (and $_REQUEST too).

ryon420 agrees: A sad day in the PHP forum when we have to explain something so simple.
