We're trying to use rgar to read the $entry
from a given field, but there is no $entry
variable accessible. When we change the function to populate_posts ( $form, $entry ) the page fails to load. How can we access the $entry
variable? Thanks
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 ) {
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
$posts = get_posts( 'numberposts=-1&post_status=publish' );
$choices = array();
foreach ( $posts as $post ) {
$choices[] = array( 'text' => $post->post_title, 'value' => $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;
}
