Drop Down of Posts in Category?

I'd like to make a form for our users to pick things like "favorite podcast from 2010". All podcasts are in the "podcast" category so my question is:

How can I populate a drop-down with a list of all Post Titles from a specified Category in a specified date range?

I haven't created the form yet, but this will go up at http://www.causticsodapodcast.com/ when ready.

Amazing quick response. Thanks!

Hi Carl,

I tried doing this, but it only works on the live form.
For some reason I can't see the choices on the admin page (I still see "First Option, Second Option, Third Option")

Any idea what I'm doing wrong?

Here is my code hook:

add_filter("gform_pre_render", "populate_dropdown");

add_filter("gform_admin_pre_render", "populate_dropdown");

function populate_dropdown($form) {

	$vectors = array();
	$vectors[0] = array("value" => "pJ201", "text" => "pJ201");
	$vectors[1] = array("value" => "pJ204", "text" => "pJ204");
	$vectors[2] = array("value" => "pJ206", "text" => "pJ206");
	$vectors[3] = array("value" => "pJ241", "text" => "pJ241");
	$vectors[4] = array("value" => "pJ244", "text" => "pJ244");
	$vectors[5] = array("value" => "pJ246", "text" => "pJ246");

	foreach($form["fields"] as &$field) {
        	if($field["adminLabel"] == "Vector"){
           		$field["choices"] = $vectors;
		}
        }
	return $form;
}

So... I took the above code from the example at: http://www.gravityhelp.com/documentation/page/Gform_pre_render

You'll notice I'm hooking into both "gform_pre_render" and "gform_admin_pre_render".

What does "gform_admin_pre_render" do then?
Is there a way to populate the list in the admin side?

Thanks,

Alan

OK.

I am trying to find a way to let the admin users create conditional logic based on values that would come from our database. Perhaps I am attacking this the wrong way.

Is there a way to populate the list in the admin side? Or is there another form of functionality that would allow me do this?

I see.

Is there a workaround you could suggest?

Is there a way to populate something like a hidden field with code, and then drive the conditional logic off that?

Or is there someway to show / hide fields dynamically with code hooks?

Thanks again,

Alan

Is it possible to populate a drop-down using a wp_nav_menu? I'm building a site for a restaurant with 22 different locations, and one of the forms is a newsletter signup. I've got the locations list populating in various parts of the site from a WP Menu, and was wondering if I can use that to generate the drop-down, so they don't have to edit the list in multiple locations if there are changes.

Thanks!

Hey!

What's the situation with dynamically populating drop downs AND combining it with conditional logic options?

I would like to create a site where people:
Choose country (countries ready)
This opens new drop down 'University in Spain' (i.e. if country=Spain)
Then there would be a text field where you could insert new university if it's not in the drop down list. And this entry would be in the drop down list (University in Spain) for next user who uses the form.

So is there any way to do this?

Ok..

So I'm going to do it without the conditional logic. What would I need to add to get the dynamic population to work for the 'City' drop down. If the City that a form user wants to select is not ready in the drop down list, he would be able to write to the 'City if not in the list' and next user of the form would see that one in the 'City' drop down. I tried to follow the guide, but didn't quite get how I should determine that it takes the text from the 'CIty if not in the list'.

Hi - I am doing something wrong! I, too, want just a category to show up in my drop down. The category name is Now Booking. The slug is now-booking. the cat id is 61.

Here is my functions code that is currently pulling up ALL posts, not the specific category I am trying to get:

<?php

// update the '51' to the ID of your form
add_filter('gform_pre_render_1', 'populate_posts');
function populate_posts($form){

    foreach($form['fields'] as &$field){

        if($field['type'] != 'select' || strpos($field['cssClass'], 'populate-posts') === false)
            continue;

        // you can add additional parameters here to alter the posts that are retreieved
        // more info: http://codex.wordpress.org/Template_Tags/get_posts
        $posts = get_posts('category=now-booking&numberposts=-1&post_status=publish');

        // update 'Select a Post' to whatever you'd like the instructive option to be
        $choices = array(array('text' => 'Select a Post', 'value' => ' '));

        foreach($posts as $post){
            $choices[] = array('text' => $post->post_title, 'value' => $post->post_title);
        }

        $field['choices'] = $choices;

    }

    return $form;
}
