Multi select update

I have placed 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]);
}
}
?>

and have the following multi select:


<select class="formListfield_Medium" name="User_Update_group_1_ExpertiseAreas[]" id="User_Update_group_1_ExpertiseAreas" tabindex="19" multiple="multiple">
<option value="">Please select your expertise areas </option>
<?php
do {
?>
<option value="<?php echo $row_rsExpertise['ExpertiseField']?>"><?php echo $row_rsExpertise['ExpertiseField']?></option>
<?php
} while ($row_rsExpertise = mysql_fetch_assoc($rsExpertise));
$rows = mysql_num_rows($rsExpertise);
if($rows > 0) {
mysql_data_seek($rsExpertise, 0);
$row_rsExpertise = mysql_fetch_assoc($rsExpertise);
}
?>
</select>

The problem I have is that lose previously stored selects when I try and update. What would I need to change so it holds previously selected multi items?

Many thanks

I think the real problem is the database design.

You shouldn't be storing a comma separated list of values in a column of your table. this is a bad database design.

instead you should be using a linking table and use the Data Assist Manage relational table behavior.

There is a tutorial for this on the data bridge support page:

It requires hand coding to accomplish.
