I am developing a website that has a section called listings to list products.

these products are divided into 17 categories. Each category has several sub-categories.

I would like when user is entering information into cms for a new listing to have a dropdown list with 17 categories. Then they have a sub-category dropdown list that is populated with the sub-categories for the category they selected.

the categories and sub-categories would not be created by the user, but by the admin only.

i believe post http://www.interactivetools.com/forum/gforum.cgi?post=71509;search_string=list%20field%20populated%20based%20on%20another%20field%20selection;#71509 may be what i need, but cannot get it to work.

any suggestions?

Hi,

This can be done by using the "Get Options From MySQL Query (advnaced)" option for your sub_categories list field.

Let me know the names as well as the setup options of both of your list fields and I can take a closer look.

Hope this helps.

Hi 4cdg,

To accomplish this, your Subcategories will need to be in a Multi Record section. To simplify things, you can also keep your Categories in a section.

First, create a Multi Record section called Categories. I'll assume you'll be using the default 'title' field to fill in their names. Add a record for each category.

Next, create a Multi Record section called Subcategories. Add a List Field to it called 'Category' and set these options:

List Options: Get options from database (advanced)
Section Tablename: category
Use this field for option values: num
Use this field for option labels: title

Now, go and add records for each of your Subcategories, making sure that you select the correct Category from the dropdown for each.

Finally, in your Products section, you'll want a Category List Field (exactly like the above one) and a Subcategory List Field with these options:

List Options: Get options from MySQL query (advanced)

SELECT num, title
FROM `<?php echo $TABLE_PREFIX ?>subcategories`
WHERE category='<?php echo $ESCAPED_FILTER_VALUE ?>'

Advanced Filter: Refresh list when this field changes: category

I hope this helps! Please let me know if you have any questions.
All the best,
Chris

Hi Chris,

Get options from MySQL query [/#333333][/#333333][/#888888][/#888888](advanced)[/#333333][/#333333] do not seem to work with Searching (Label|FieldList|searchType).

You confirm ?

Thanks !

In fact, that functions if I use : WHERE field LIKE '%<?php echo $ESCAPED_FILTER_VALUE ?>%'

and does not function if I use : WHERE field = '<?php echo $ESCAPED_FILTER_VALUE ?>'

If I use LIKE, it is correct ?

Thanks for the feedback ! :)

Hi Djulia,

You'll need to use LIKE if your `field` is a multi-value list field. Actually, you should use this instead:

WHERE field LIKE '%\t<?php echo $ESCAPED_FILTER_VALUE ?>\t%'

...so that you don't get false positives.

That's correct: "Get options from MySQL query (advanced)" do not work with CMS Builder's list page search functionality. If this is important, our consulting department can write you some custom code to search any way you want. Please let me know if that's something you're interested in.

I hope this helps! Please let me know if you have any questions.
All the best,
Chris

Hi Chris,

>> WHERE field LIKE '%\t<?php echo $ESCAPED_FILTER_VALUE ?>\t%'
Your proposal does not function on my server.

>> ...so that you don't get false positives.
Is that a big risk ?

Thanks !
