Checkbox Form

[TheFilmGod]

<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" />

 

I would like to extract the submitted info. Since the checkboxes are already in an array how can I use php to simple do this:

 

If checked $element = 1

 

if not checked $element = 0 ?

 

I'm new to php and forms, and I finally stopped copying and pasting and started writing my scripts but as you see, that is HARD!! LOL.

Only checked values will be posted.

<?php
foreach ($_POST['activity'] as $act)
{
     // process activity
     echo $act
}

Is there a way I can simple do this:

 

$_POST['activity][1]?

[chronister]

you can, but it will only give you the second item in the array. You will lose the rest of the checked items

 

Anytime your dealing with an array, you will have to do a loop to extract all the results. If you know there are only going to be X number of items, then you can address them using the $_POST['activity'][X], but that can get tedious if there are more than a few items.

 

Loops are your friend
