php checkbox question

[katmac]

Hi

I have a form with a list of checkboxes (http://mandatorymarketinginc.com/web/sample-01.png)

These checkbox values were previously saved to a table called "comp-profile-03-specialties" and I got code working on the html form to to check and if specialty selected the checkbox is checked.

On the html form checkboxes name is "specialties[]".

However my problem comes in when I want to update the checkboxes to account for the possibilities if the a checkbox is de-selected or another checkbox is added.

How would I go about doing this?

Thanks.

If the checkbox is checked, the value of it will be passed. Otherwise it won't.

<?php
if (isset($_POST['mycheckbox']))
{
    echo "checked!";
}
else
{
echo "Not checked";
}
?>

It would be sooo much easier to help if you would post the code.

Since i don't know where you are with your code, i can only suggest you that before the form you collect relevant values with mysql query and check it while parsing the form:

echo '<option value="'.$var.'"'.($checked['value'] == $var ? ' selected="selected">' : '>').$name.'</option>'."\n"; 

This way saved and changed values are compared and changed or not with next submit...
