Validate a field from a recordset

Validate a field from a recordset

Hi,
I have an insert page to insert a 'product'. A Supplier cannot insert a product without a valid supplier number. I wish to validate the first field on my insert page - 'Supplier Number' by looking up a (Suppliers) recordset.
I know I could use a drop down list and popluate it from the recordset, but I dont wish to do this.

I want to be able to add some kind of behaviour - on blur - to lookup the suppliers recordset and display a message if not a valid supplier.

Or is there a better way to do this?

Please help!

Very good.

The first thing you will to do is add the suppliers record set to you insert page. In the record set window add a filter. Select the Supplier Number column and use "=" and then select Form Variable and type the name of the Supplier Number input field you have in the insert page.

Second, Select the error message that you want to display, and in the Server Behaviors Panel (Window -> Server Behaviors) click the + button and choose Show Region and select Show if Record Set is not empty.


Last, you will need to add the same condition to the DataAssist Insert Server Behavior. Basically copy the top line of the show if server behavior which look something like this:

<?php if ($totalRows_WAContents > 0) { // Show if recordset not empty ?>

and place it at the top of the DataAssist insert Server behavior. So you should have something like this:

<?php if ($totalRows_WAContents == 0) { // Show if recordset empty ?>
<?php
// WA Application Builder Insert
if (isset($_POST["Insert_x"])) // Trigger
{

and you will also need to need to add this line to the bottom of the DataAssist Insert Server Behavior:

<?php } // Show if recordset not empty ?>


If you have any question about these steps, please send me your insert page in a zip and i should be able to assist you. Please remember that the code i have above is an example and the names will be different.

Not quite there

Hi dani,

I get what you are doing here, however, it would appear backto front to me.

I need to display "Not a valid Supplier number" and only insert a record if the supplier number entered is valid.

I would have expected this
For form element

<?php if ($totalRows_rs_suppliers == 0) { // Show if recordset empty ?>
Not a valid Supplier Number
<?php } // Show if recordset empty ?>

On Insert
if ($totalRows_rs_suppliers > 0) { // Insert if recordset not empty
// WA Application Builder Insert


Either way it is not working for me. I have attched code if you wish to have a look.

Note : I am looking up 'suppliers' (sslsuppliers)for validation and inserting into 'product labels' (ssllabel )
Thanks

You almost have it right, it looks like you just need to switch the conditional statement. So yo should have:

<?php if ($totalRows_rs_suppliers > 0) { // Show if recordset not empty ?>
Not a valid Supplier Number
<?php } // Show if recordset empty ?>


and


if ($totalRows_rs_suppliers == 0) { // Show if recordset empty
for the insert server behavior.

Still no joy

Hi Dani,

I still havent got this right.
I amended my code as above. When I input a valid supplier - no record gets inserted. When I put an invalid code in, a record Does get inserted. So its the wrong way around!

Also, I didnt get a error message for my invalid supplier. Either way, the message is never displayed!
Is this the error message in the correct place???

I have attached the updated code.
Thanks for the help!
