[SOLVED] Checkbox PHP

[TheFilmGod]

I have a form. I got the mysql to work but I can't get one thing done: Checkboxes!!! ARG!!!

 

HTML Form Snippet

 

<p>
			Brunch
  		<input type="checkbox" name="activity[]" value="brunch" />
		<br />Dance
	<input type="checkbox" name="activity[]" value="dance" />
		<br />Game
  		<input type="checkbox" name="activity[]" value="game" />
</p>

 

// Call the checkbox inputs
		$activity = $_POST['activity'];

		// Define each checkbox its value
		$brunch = $activity[0];
		$dance = $activity[1];
		$game = $activity[2];

		echo "$brunch";
		echo "$dance";
		echo "$game";

		// if checkbox was checked it gives Y otherwise an N
		if ( $brunch == "brunch" ) {

			$brunch = "Y";
		}
		else {

			$brunch = "N";
		}

		if ( $dance == "dance" ) {

			$dance = "Y";
		}
		else {

			$dance = "N";
		}		

		if ( $game == "game" ) {

			$game = "Y";
		}
		else {

			$game = "N";
		}	

 

Half of the time it works. But sometimes it doesn't. "GAME" seems to be buggy. It doesn't work by itself!

Try dumping the raw info using print_r($_POST).

 

EDIT: Ah, forgot! You can't store values in a checkbox. It's either on or off. One thing you could try is setting some different indexes for your control, like this:

<p>
<input type='checkbox' name='type[brunch]'>
<input type='checkbox' name='type[dance]'>
<input type='checkbox' name='type[game]'>
</p>
...
<?
//Check submit
$type=$_POST['type'];
foreach ($type as $key => $value) {
echo "$key: ".($value ? "Y" : "N")."<br>";
}
?>

well when I echo the $brunch for example I get brunch. This only happens when its checked.

 

I just don't understand this array stuff! I simply want to know which values where checked. If checked they get a value of "Y" and an "N" if not. Please help! I"m on a time constraint!

You can put checkboxes in a sub array of $_POST and you can define values for them.  However, the way you have your code setup, they won't necessarily be in the same order each time...from your snipped, if I check all three boxes, then they will be available at array index positions 0, 1, and 2.  However, if I chose only the last 2, then they will still be in 0 and 1, but not 2...you need to force them to be in the place you want...

 

Brunch
  		<input type="checkbox" name="activity[0]" value="brunch" />
		<br />Dance
	<input type="checkbox" name="activity[1]" value="dance" />
		<br />Game
  		<input type="checkbox" name="activity[2]" value="game" />

 

Remember that with checkboxes, if they box isn't checked, it's not included with the POST at all.
