[FX.php List] Suggestions on editing a list of check boxes

[Bob Patin]

Hi John,

I thought we talked about this the other day...

I have my own method, which works great; I'm sure there are other  
methods, but this one is fairly easy:

On your form:

If you are creating a dynamic set of checkboxes, you'll need to make  
sure each checkbox's name is unique. I do this with a counter:

$counter = 0;

Then, in a FOREACH loop, generate your checkbox HTML code, and make  
the name end with the counter variable:

name="myCheckbox_<?php echo $counter; ?>"

I use an underscore just to make it easy for me to read...

Then, after this FOREACH loop, put an invisible field that contains  
the value of $counter; you'll use this on the processing page.
---------------
ON THE PROCESSING PAGE:

//retrieve the value of your COUNTER variable
$counter = $_POST['counter'];

Retrieve the checkbox values by using a WHILE loop:

$x = 0;
while ($x < $counter){
	$myCheckboxList = $_POST['myCheckbox_'.$x].'<br>';
	$x++;
}

Then, in your EDIT query, write the value of $myCheckboxList to your  
checkbox field.

I'm doing this all from memory, but that's essentially how I do it.  
You don't really need to use an array, since you're grabbing the  
checkbox values and assembling them into a list that you'll write to  
the field.

Hope this makes sense; I'm too lazy to dig up one of my pages and copy  
out the code...
