Current value for Multiple Select Menu

Current value for Multiple Select Menu

I changed a Menu to multiple select (and yes, added [] to the select value). My problem is, in Update, it's not pulling in existing selection(s). Here's the code:

<select name="category[]" size="5" multiple="multiple" id="category">
<?php
do {
?>
<option value="<?php echo $row_WADADynListcompanies_type['name']?>"<?php if (!(strcmp($row_WADADynListcompanies_type['name'], $row_WADAcompanies["category"]))) {echo "selected=\"selected\"";} ?>><?php echo $row_WADADynListcompanies_type['display']?></option>
<?php
} while ($row_WADADynListcompanies_type = mysql_fetch_assoc($WADADynListcompanies_type));
$rows = mysql_num_rows($WADADynListcompanies_type);
if($rows > 0) {
mysql_data_seek($WADADynListcompanies_type, 0);
$row_WADADynListcompanies_type = mysql_fetch_assoc($WADADynListcompanies_type);
}
?>
</select>


- What am I missing here?

THANKS

===> ADDITIONAL INFORMATION
I see that DataAssist isn't storing the data properly in the db when I INSERT a new record (and I'm sure when I UPDATE). It's putting the word "Array" in the db instead of the array itself. What to do? What to do...?

===> FURTHER UPDATE
I can easily change the Update page to insert the correct information into the db field using IMPLODE. In the Application Builder section I changed $_POST["category"] to implode(",",$_POST["category"]) and it inserts a comma separated list into the db field as I want. Now the problem is....how do I get the Update page to display those as selected in a multiple select field?

in the code that creates the list, you need to use the explode() and in_array() function to convert the comma seperated list back into an array and check if the current list item is in that array.

in your previous post, you give the following code for writing the list options:

php:
<option value="<?php echo $row_WADADynListcompanies_type['name']?>"<?php if (!(strcmp($row_WADADynListcompanies_type['name'], $row_WADAcompanies["category"]))) {echo "selected=\"selected\"";} ?>><?php echo $row_WADADynListcompanies_type['display']?></option>





you would need to change that to:

php:
<option value="<?php echo $row_WADADynListcompanies_type['name']?>"<?php if(isset($row_WADAcompanies["category"]) && is_array(explode(", "$row_WADAcompanies["category"]))) { 

if(
in_array($row_WADADynListcompanies_type['name'], explode(", "$row_WADAcompanies["category"]))) echo(" selected=\"selected\""); 

?>><?php echo $row_WADADynListcompanies_type['display']?></option>

Beautiful! I had to get rid of a space in two places [explode(", ",)] but it works a charm. The only "problem" is it's actually a pretty bad way to handle this on an update page as it turns out, since all you need to do is click on one other option wanting to add it but not holding down Ctrl and you'd better hope you remember the original options!

But it works a charm.

THANKS!
