Dynamic Drop Downs On Update Form

Dynamic Drop Downs On Update Form

Im having trouble getting Dynamic Drop Downs to work on my UPDATE page.

My form has two dropdowns (1 parent, 1 child)

I have done the following:
1. Applied dynamic values options from recordsets to both dropdowns.
2. Added server behavior "create dynamic array"
3. Applied to BODY tag, behavior "Populate List From Array"
4. Applied to BODY tag, behavior "Set Selected In List".

I found these instructions in another forum post. Is there a clear step-by-step tutorial on this?

Currently when the form loads, the PARENT dropdown populates as required, but the CHILD does not. The child appears empty with no dynamic list options to choose from.

Could someone please help me with a step-by-step on getting dynamic dropdowns to work on my update form.

My body tag code is:
<body onload="WA_FilterAndPopulateSubList(rsSubCategories_WAJA,MM_findObj('categoryID'),MM_findObj('subCategoryID'),0,0,false,': ');WA_setSelectionsInChildList(MM_findObj('subCategoryID'),<?php echo $row_WADAws_inventory['subCategoryID']; ?>)">

Thanks. D.

the problem is in the way the Create Dynamic Array behavior has been configured, you have set the Parent ID, Child ID and Child name all to use the categoryName column of the rsSubCategories recordset.

When I "Create Dynamic Array" it looks like (see attached)

All 3 are not all 3 the same. They are as follows:

Recordset: rsSubCategories
Parent ID Field: categoryName
Child ID Field: subCategoryName
Child Text Field: subCategoryName

I have also tried is as the following and it will not work:

Recordset: rsSubCategories
Parent ID Field: categoryID
Child ID Field: id_subCategory
Child Text Field: subCategoryName

Is what I enter in the wizard not translating to the code properly? I really appreciate any help you can provide me. Thanks.

if you could provide a link where i could see the problem in the browser, i would be better able to see what is going on to spot the problem.

I have created a support ticket so we can look into this issue further.

Thought I would post back the results of my ticket for other to see:

My Dynamic Dropdowns consist of 1 parent and 1 child. Both dropdowns assign a text (not numeric) value to the database. I do this for a number of reasons. So instead of inserting into the database a number like "2" it will assign a text value in the database like "Car".

To get my dropdowns to work on my update page if did the following steps:

1. Populate the parent dropdown from a recordset.
2. Populate the child dropdown from a recordset.
3. Create Dynamic Array SB
4. Then applied the following 2 behaviors to my opening body tag via the behaviors palette.
a. populate list from array.
b. set selected in list
5. The above made by opening body tag look as follows:

<body onload="WA_FilterAndPopulateSubList(rsSubCategories_WAJA,MM_findObj('categoryID'),MM_findObj('subCat egoryID'),0,0,false,': ');WA_setSelectionsInChildList(MM_findObj('subCategoryID'),<?php echo $row_WADAws_inventory['subCategoryID']; ?>)">

The generated body tag code assumes that the dropdowns will be assigning numeric value to the database (not text as I need to do as described above). To allow text, change the body tag to:

<body onload="WA_FilterAndPopulateSubList(rsSubCategories_WAJA,MM_findObj('categoryID'),MM_findObj('subCat egoryID'),0,0,false,': ');WA_setSelectionsInChildList(MM_findObj('subCategoryID'),'<?php echo $row_WADAws_inventory['subCategoryID']; ?>')">

It looks almost idenitcal, the only difference is two ' marks. I've highlighted them in the attached JPG.

This edit prevents a JavaScript Error from occurring.

Hope this helps someone else. Thanks Jason. I appreciate the support.

Hi,

Does anyone know how to add a server behavior to the body tag when you are using a template?
You cannot edit the text in the body tag if you are using a template

Thanks

Body Tag

set the body tag in its own editable region i.e.

<!-- TemplateBeginEditable name="bodysection" -->
<body>
<!-- TemplateEndEditable -->

then you can amend as required
