pre-populating hidden form field problems.

In the Dynamic Field Population

"In version 1.1.3 we introduced the ability to pass data from the form to the redirect page of your choice. In version 1.2 we have taken that a step further with the ability to pre-populate form fields using query string parameters, filters, shortcode or function call."

So how do I pass the shortcode of [plexus var="agent" /] to the field?

This shortcode is available on every page of our website.

Carl,

The instructions that Alex gave me are for a completely different issue (that has been solved), This issues has nothing to do with the other one. The form being used for this issue is on a completely different website.

I guess what I am not understanding is this part of the product feature description.

"In version 1.2 we have taken that a step further with the ability to pre-populate form fields using query string parameters, filters, shortcode or function call.""

How do I PRE populate a field using a shortcode?

If I can only use GravityForm shortcodes and no other WordPress shortcodes to pre populate fields then shouldn't the feature description say that? Right now the way it reads it makes people think that they can use any WordPress shortcode to pre-populate any field which if I understand you correctly is not the case.

Thanks.

So if I wanted to pass:

<?php plexus_information("agent"); ?>

Would this work in my function.php?

add_filter("gform_field_value_agent", "populate_agent");
function populate_agent(){
return .plexus_information("agent").;
}

My agent text box would then be ticked to allow dynamic population, and called 'agent'.

Am I on the right track here?

hhhmmm... the field is still blank. Does the Field Label also have to be called "agent"?

Carl,

Nope, no BR line breaks in the code.

Carl,

Yup, that put "Test" in the field.

Carl,

We call it on every singe page of our website and it's works fine. We use the php to place it in the sidebar

<?php plexus_information("agent"); ?>

and the shortcode to place it in certain pages.

[plexus var="agent" /]

It outputs a 5 digit agent id number. Only numeric digits.

For example: 86740

Caril,

I'll just edit our our database URL info and post it below.
