Checkbox group

Hi, I wonder if someone could assist. I have a checkbox group with 23 checkboxes which I want to insert into one data field. When I ran through SA2, it left a blank ie no checkboxes so I added them manually after the pages were made.

I understand that I the following change to each checkbox:

From:

<input type="checkbox" name="Registration_group_1_ExpertiseAreas" value="Trauma" id="Registration_group_1_ExpertiseAreas_22">

To:

<input type="checkbox" name="Registration_group_1_ExpertiseAreas[]" value="Trauma" id="Registration_group_1_ExpertiseAreas_22">

I believe I then have to make adjustments to:

"".((isset($_POST["Registration_group_1_ExpertiseAreas"]))?$_POST["Registration_group_1_ExpertiseAreas"]:"") .""

using explode? Is this the code I need to change? Any idea what the code should look like or any help whatsoever would be much appreciated?

add the following code at line 1:

<?php

if($_SERVER["REQUEST_METHOD"] == "POST")     {

    foreach($_POST as $key => $val) {

        if(is_array($_POST[$key])) $_POST[$key] = implode(", ", $_POST[$key]);

    }

}

?>

that will automatically convert the array to a string for you, no other adjustments needed.

Many thanks Jason - greatly appreciated!!! Just one more question as a result of looking at something Ray posted a while back. Can you do the same thing with a multi-select list?

yes, the same technique can be used with multiple select lists.

Thanks again Jason

I am using the group checkboxes on the registration page and it is working perfectly thank you Jason.
However, having applied the same to the update page, it won't insert any of the checkbox values. Is there anything I am missing here?

Any chance of a response? Thanks

can you send a copy of the page so i can look at the code.

Thanks Jason, see attached

sorry, here it is
