How do you make a Dynamic Form auto populate fields?

I am using PHP and mySQL.

I have a fully functional DataAssist Insert form that inserts records into a mySQL table.

For the first two inputs on the form, I have separate dynamic combo boxes that read from 2 separate recordsets. These queries look for specific information from different tables. If the 1st combo box selection is chosen, it will change the options in the second combo box. When the 2nd combo box is selected, the data that is chosen will dynamically determine what will auto populate the remaining text boxes with initial values. The remaining form fields will not have initial values until the 2nd combo box is selected.

1st Combo Box to get the Name for Table1

<select size="1" id="name" name="name">
<option value="-1" selected>Not Selected</option>
<?php
do {
?>
<option value="<?php echo $row_getTable1['record_id']; ?>"><?php echo $row_getTable1['name']; ?></option>
<?php
} while ($row_getTable1 = mysql_fetch_assoc($getTable1));
$rows = mysql_num_rows($getTable1);
if($rows > 0) {
mysql_data_seek($getTable1, 0);
$row_getTable1 = mysql_fetch_assoc($getTable1);
}
?>
</select>



2nd Combo Box to get the Department for Table2

<select size="1" id="department" name="department">
<option value="-1" selected>Not Selected</option>
<?php
do {
?>
<option value="<?php echo $row_getTable2['record_id']; ?>"><?php echo $row_getTable2['department']; ?></option>
<?php
} while ($row_getTable2 = mysql_fetch_assoc($getTable2));
$rows = mysql_num_rows($getTable2);
if($rows > 0) {
mysql_data_seek($getTable2, 0);
$row_getTable2 = mysql_fetch_assoc($getTable2);
}
?>
</select>



How is this accomplished?

Getting your two combo boxes to work together so that the second is dependent on the first can be accomplished using the WebAssist Dynamic Dropdowns tool. It will allow you to create a dynamic client side array for the second select list that will be filtered based on your selection from the first select list. You could do this manually also, you would need to craft the js code to create an array like this and the code to filter and populate based on the selection. If you own any of the development suites then you probably already own this tool.

The final part where you populate the other form elements based on second selection will be more custom though, you would need to make sure you have an array of all the records and values for them then filter it based on the second list.

Eric,

Thanks for pointing me in the right direction. Yes I have the Super Suite, but that is one product that I've never used.

I'll download it and see what I can accomplish.

Thanks again! :)

After you install the tool you should go to the help within Dreamweaver for an example of the functionality and see how it is accomplished. Let us know if you have any troubles.
