DB lookup vs Query ?

krileon wrote: You're already setting the ID to a CB field so you can do a query in a CB Query Field and substitute in the ID as needed. This won't be ajax of course and is only going to display on profile for example.

This is the point, we need something to display on registration and not on profile.
And if we do a query, this is failing because the query does not seem to get the ID set by js in time.
I have set the ID by autoaction prior to displaying the registration form but there is no way to make the Query work with the substitution.

Do you have an idea ?
I can have the id set as a variable to the url also, could it help to be retrieved prior to the display of the registration form and then work in the query ?
Is there no way to check fields with CB table dynamically during the registration ?

You'll need to custom develop something then. We don't have anything to provide this.

Well we don't have the knowledge for it.
Could you suggest someone ? or would CB team do it for an amount ?

In the meanwhile I tried to make it another way by making the CB field containing the ID set by js a condition for displaying another field but this does not work neither.

The condition does not display the second field on first display of the registration form, only if I click on the first field and click enter, then it works.

Seems a problem with CB conditional plugin

You may want to look into hiring someone to develop it for you then.

We don't do contract development, sorry.

You could also try using CB Auto Actions to add jQuery to the page that performs an AJAX call and adds the response as HTML to the page; this is probably the most simple solution, but it's still going to take some coding experience as you need to be familiar with jQuery. You can find information on jQuerys AJAX usage below.

You can not set field values using JS and expect anything to work, it won't. Setting a value with JS does not fire events down the DOM. So no other JS knows the field ever changed. You'd need to fire the change event so other JS can be informed of the change (e.g. with jQuery: $( '#cb_myfield' ).trigger( 'change' ); ).

Well I tried with both change and keyup but it does not work, where can I check the proper syntax for CB ? I guess it works on enter only

My code is :

<script type="text/javascript">
PostAffTracker.writeAffiliateToCustomField('cb_parrain');
jQuery( '#cb_parrain' ).trigger( 'change' );
</script>

You're using PostAfPro API, your change trigger probably is happening before the field is changed. You need to see if PostAfPro has a callback that you can add a function to that'll fire the change event on the field. CB Conditional acts on change and keyup.
