动态填充的 GF 下拉列表与事件日历专业版

Question

>我有一个动态填充的 GF 表单，它从事件日历专业版中提取 CPT。我正在尝试按升序标题对事件进行排序，我还想隐藏所有过去的事件。我做了很多试验和错误，因为我不是PHP开发人员。我一直在尝试添加排序和隐藏一段时间，此时我只是在旋转我的轮子。蒂亚。任何帮助，不胜感激。

下面是提取 CPT 并将其正确显示在下拉列表中的代码。

add_filter( 'gform_pre_render_1', 'populate_posts' );
add_filter( 'gform_pre_validation_1', 'populate_posts' );
add_filter( 'gform_pre_submission_filter_1', 'populate_posts' );
add_filter( 'gform_admin_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 retrieved
// more info: http://codex.wordpress.org/Template_Tags/get_posts
$posts = get_posts ('post_type=tribe_events&numberposts=-1' );
$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 an Event';
$field->choices = $choices;
}
return $form;

}

你可以使用 tribe_get_events(( 函数代替 get_posts(( https://theeventscalendar.com/knowledgebase/using-tribe_get_events/

<?php
add_filter( 'gform_pre_render_1', 'populate_posts' );
add_filter( 'gform_pre_validation_1', 'populate_posts' );
add_filter( 'gform_pre_submission_filter_1', 'populate_posts' );
add_filter( 'gform_admin_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 retrieved
// more info: http://codex.wordpress.org/Template_Tags/get_posts
// Retrieve all upcoming events
$events = tribe_get_events( array(
'posts_per_page' => -1,
'start_date'     => date( 'Y-m-d H:i:s' ),
) );
$choices = array();
foreach ( $events as $event ) {
$choices[] = array(
'text'  => $event->post_title,
'value' => $event->post_title
);
}
// update 'Select a Post' to whatever you'd like the instructive option to be
$field->placeholder = 'Select an Event';
$field->choices = $choices;
}
return $form;
}

<?php

continue;
}
// you can add additional parameters here to alter the posts that are retrieved

// Retrieve all upcoming events
$events = tribe_get_events( array(

) );
$choices = array();
foreach ( $events as $event ) {
// These two lines of code will get the event start date in the specified format
$start_date = strtotime(tribe_get_start_date($event->ID));
$start_date_day = date('Y-m-d', $start_date);
$choices[] = array(
'text'  => $event->post_title . ' ' . $start_date_day,
'value' => $event->post_title

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