Gravity form - populate drop down select based on page URL WordPress

Sébastien | French WordpressDesigner comments:

You need to customize the line
$posts = get_posts( 'numberposts=-1&post_status=publish' );

In your case you can replace by
$posts = get_posts( 'post_type=page&numberposts=-1&post_status=publish' );
or
$posts = array(
'page 01' => 'www.example.com/page01',
'page 02' => 'www.example.com/page02',
'page 03' => 'www.example.com/page03',
'page 04' => 'www.example.com/page04',);

Hi - what do I call my drop-down select field?

I've tried Select a Post and used:

$posts = array(
'page 01' => 'www.mydomainhere.com/webinar-sts-06-15-17/',
'page 02' => 'www.mydomainhere.com/webinar-sdl-06-20-17/',
);

It doesn't change the value when I load the second page.

Sébastien | French WordpressDesigner comments:

you need to use the exact title and the exact URL
Your array will be :


$posts = array(
'page 01' => 'http://www.mydomainhere.com/webinar-sts-06-15-17/',
'page 02' => 'http://www.mydomainhere.com/webinar-sdl-06-20-17/',
);

Austin comments:

Hi - what do mean by exact title?

And what do I call my field?

Austin comments:

You understand that I need to pre-select the value based on the URL of the page?

Sébastien | French WordpressDesigner comments:

we only want to modify fields that are select (drop down) fields AND have a CSS class titled "populate-posts".

Austin comments:

It's not doing anything yet.

I have a drop down field created:

Label: My Page

Custom CSS: populate-posts

values:

page 01
page 02

And in functions.php

$posts = array(
'page 01' => 'http://www.mydomain.com/webinar-sts-06-15-17/',
'page 02' => 'http://www.mydomain/webinar-sdl-06-20-17/',
);

Sébastien | French WordpressDesigner comments:

yes I understand :)

If you use
$posts = array(
'page 01' => 'http://www.mydomainhere.com/webinar-sts-06-15-17/',
'page 02' => 'http://www.mydomainhere.com/webinar-sdl-06-20-17/',
);

you need to replace this code

$choices = array();

foreach ( $posts as $post ) {
if ($current_post === $post->post_name) {
$choices[] = array( 'text' => $post->post_title, 'value' => sanitize_title($post->post_title), 'isSelected' => true );
} else {
$choices[] = array( 'text' => $post->post_title, 'value' => sanitize_title($post->post_title) );
}
}

by this one :


$choices = array();


foreach ( $posts as $k => $v ) {
if ($current_post === $v) {
$choices[] = array( 'text' => $k, 'value' => sanitize_title($k), 'isSelected' => true );
} else {
$choices[] = array( 'text' => $k, 'value' => sanitize_title($k) );
}
}

Austin comments:

Hi - I still can't get this to work.

The nearest I have found to want I need is:

/**
* Pre Select a dropdown choice/option in Gravity Forms
*
* Create a dynamic list of dropdown choices from a custom post type
* Based on the current page, pre-select a choice in the drop down
*
* @var howto_dynamic_field = the dynamic field set in Gravity Forms on the field group under the Advanced tab
* @var howto_post_type = Your custom post type you are listing in the drop down
*
*/
add_filter( 'gform_pre_render_1', 'howto_preselect_dropdown' );
add_filter( 'gform_pre_validation_1', 'howto_preselect_dropdown' );
add_filter( 'gform_pre_submission_filter_1', 'howto_preselect_dropdown' );
add_filter( 'gform_admin_pre_render_1', 'howto_preselect_dropdown' );

function howto_preselect_dropdown( $form ) {

global $post;

$current_post = $post->post_name;

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

if ( $field->type != 'select' || strpos( $field->inputName, 'howto_dynamic_field' ) === false ) {
continue;
}

$args = array(
'post_type' => 'page',
'order' => 'ASC',
'orderby' => 'title',
'posts_per_page' => -1
);
$posts = get_posts( $args );

$choices = array();

foreach ( $posts as $post ) {
if ($current_post === $post->post_name) {
$choices[] = array( 'text' => __($post->post_title, 'ozh_reap'), 'value' => sanitize_title($post->post_title), 'isSelected' => true );
} else {
$choices[] = array( 'text' => __($post->post_title, 'ozh_reap'), 'value' => sanitize_title($post->post_title));
}
}

$field->placeholder = 'Select';
$field->choices = $choices;

}

return $form;
}

Sébastien | French WordpressDesigner comments:

and the name of your select is well "howto_dynamic_field" ?

Sébastien | French WordpressDesigner comments:

This is the code you need, but your select must have the class "populate-posts", of course :


<?php

add_filter( 'gform_pre_render_51', 'populate_posts' );
add_filter( 'gform_pre_validation_51', 'populate_posts' );
add_filter( 'gform_pre_submission_filter_51', 'populate_posts' );
add_filter( 'gform_admin_pre_render_51', 'populate_posts' );

function populate_posts( $form ) {

global $post;
$current_post = $post->post_name;

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 retrieved
// more info: [http://codex.wordpress.org/Template_Tags/get_posts](http://codex.wordpress.org/Template_Tags/get_posts)
$args = array(
'post_type' => 'page',
'order' => 'ASC',
'orderby' => 'title',
'posts_per_page' => -1
);
$posts = get_posts( $args );

$choices = array();

foreach ( $posts as $post ) {
if ($current_post === $post->post_name) {
$choices[] = array( 'text' => $post->post_title, 'value' => sanitize_title($post->post_title), 'isSelected' => true );
} else {
$choices[] = array( 'text' => $post->post_title, 'value' => sanitize_title($post->post_title) );
}
}

// update 'Select a Post' to whatever you'd like the instructive option to be
$field->placeholder = 'Select a Post';
$field->choices = $choices;

}

return $form;
}
