Server Side Validation with Dynamic Dropdowns

Hi

I have come across a strange one...

I have an add and edit form that contains a text field and select lists used as dynamic drop downs. There are just the two drop downs, one for category and one for page.

The dynamic drop downs work great.

I have since added Server Side Validation to the form post page and this works great for the text field but the values of the drop downs are behaving in a strange way.

Example One:

If I leave the text field blank (required) and set the values of both the dynamic drop downs then the values of the dynamic drop downs are repopulated correctly with the validation values.

However, if I only select the parent drop down value and leave the child blank then the values of the drop downs result in nothing and they are both set at the null value index of "Please Select..."

I hope I have explained myself OK? Just wondering if there is anything else I could try to get it to retain the parent drop down value after validation even if the child is not set (i.e. left at an item with a blank value).

Cheers
Ian

dynamic drop downs contains behaviors for Set Selected in List.

for both lists, you need to apply the set selected in list behavior to the onload event of the Body tag, and use the validated entries bindings.

the body on load event should have the following behaviors applied:
Set Selected in List - for the parent list
Populate List From Array
Set Selected in list - for the child list.

Hi Jason,

Yes, Ive already got these in place on the page but for some reason they only trigger if both the select lists were 'populated' when the validation takes place.

I'll keep looking to see if I can suss it.

Hi Jason,

Here you go, thanks.

Basically the scenarios appear to be:

1. Leave the required name blank and set both the drop downs = remembers drop down values

2. Leave the required name blank and set only first drop down = remembers neither drop downs.

Its probably something really simple and I've been staring at it so long I've not noticed it.

Regarding the files, new.php has the form and the other file has the validation in it.

Cheers
Ian

I must be missing something

1)there are no behaviors applied to the body onload event, your body tag is empty:

<body>

2) I dont see any server validation behavior applied to the _setnav1.php page

Hi Jason

Thanks for the reply.

Because it is part of a WA Framework I cannot use the Body Tag. The javascript is sat down towards the bottom of the page so that it executes after the page has populated.

It is a strange one because if both Select Lists are populated then it remembers the values. If only one is populated and the validation fails due to the menutext text field not being populated then neither get their values.

There is definitely server validation on _setnav1.php. Here it is copied from the file:

<?php
if ("" == "") {
$WAFV_Redirect = "new.php?fail=1";
$_SESSION['WAVT_new_692_Errors'] = "";
if ($WAFV_Redirect == "") {
$WAFV_Redirect = $_SERVER["PHP_SELF"];
}
$WAFV_Errors = "";
$WAFV_Errors .= WAValidateRQ(((isset($_POST["menutext"]))?$_POST["menutext"]:"") . "",true,1);
$WAFV_Errors .= WAValidateRQ(((isset($_POST["category"]))?$_POST["category"]:"") . "",true,2);
$WAFV_Errors .= WAValidateRQ(((isset($_POST["page"]))?$_POST["page"]:"") . "",true,3);

if ($WAFV_Errors != "") {
PostResult($WAFV_Redirect,$WAFV_Errors,"new_692");
}
}
?>

Cheers
Ian

EDIT : Having just downloaded the ZIP file I posted earlier you are absolutely right. The Server Validations don't appear! But the above is what is in my PHP file where I still have the same problem and I have reattached! Not sure where they came from??
