我正在尝试在用户中创建一个新列。带有按钮的php（Wordpress用户页面）。
与用户关联的每个按钮都必须创建一个页面或帖子（基于我的编程选择）。
我对如何调用函数从类内部创建页面/帖子有一些问题。
下面是我正在使用的一些示例代码：
class Create_Pages_On_User_Click {
..............
..............
..............
public function actions() {
add_filter(\'manage_users_columns\', array( $this, \'hn_create_associated_page_column\'));
add_action(\'manage_users_custom_column\', array( $this, \'hn_create_custom_pages_content\'), 10, 3);
}
// Add Create Page Column
public function hn_create_associated_page_column($columns) {
$columns[\'create_page_associated\'] = \'Page Associated Action\';
return $columns;
}
public function hn_create_custom_pages_content($value, $column_name, $user_id) {
$postID_link = get_user_meta( $user_id, \'wp_ure_posts_list\', true );
if ( \'create_page_associated\' == $column_name ) {
if ($postID_link != null) {
return \'<button type="submit" class="btn btn-btn-warning" disabled>Page Created</button>\';
} else {
$my_personal_page_name = get_user_meta( $user_id, \'wp_s2member_custom_fields\', true);
$name_of_the_personal_page = @$my_personal_page_name[\'personal_page_name\'];
//return "<a class=\'button button-primary\' id=\'submitCreatePages\' style=\'margin:0.25em 0\' href=\'{$_SERVER["REQUEST_URI"]}?create_page.php&userID={$user_id}&lb_name={$name_of_the_personal_page}\'>Create Page</a>";
// Call programmatically_create_post() on click and pass $postID_link and $name_of_the_personal_page
return \'<input id="submitCreatePages" type="submit" value="Create" class="btn btn-warning" name="action" />\';
}
}
return $value;
}
}
function programmatically_create_post() {
// Initialize the page ID to -1. This indicates no action has been taken.
$post_id = -1;
// Setup the author, slug, and title for the post
$author_id = 1;
$slug = \'example-post\';
$title = \'My Example Post\';
// If the page doesn\'t already exist, then create it
if( null == get_page_by_title( $title ) ) {
// Set the post ID so that we know the post was created successfully
$post_id = wp_insert_post(
array(
\'comment_status\' => \'closed\',
\'ping_status\' => \'closed\',
\'post_author\' => $author_id,
\'post_name\' => $slug,
\'post_title\' => $title,
\'post_status\' => \'publish\',
\'post_type\' => \'post\'
)
);
die();
// Otherwise, we\'ll stop
} else {
// Arbitrarily use -2 to indicate that the page with the title already exists
$post_id = -2;
} // end if
} // end programmatically_create_post
add_filter( \'after_setup_theme\', \'programmatically_create_post\' );
我三天来一直在解决这个问题，我需要一只大手。
提前谢谢你。

使用wp-admin/admin.php 使用action 参数：
<a href="<?php echo esc_url( admin_url( "admin.php?action=wpse_184153_create_page&user_id=$user_id" ) ) ?>">Create Page</a>
然后关注事件：
function wpse_184153_create_page() {
$redirect = admin_url( \'users.php\' );
if ( ! empty( $_GET[\'user_id\'] ) && $user = get_userdata( ( int ) $_GET[\'user_id\'] ) ) {
// Create your page
// Add any URL parameters you need for the return page
$redirect = add_query_arg( \'created_page\', $user->ID, $redirect );
}
// Send \'em back to users.php
wp_redirect( $redirect );
exit;
}
add_action( \'admin_action_wpse_184153_create_page\', \'wpse_184153_create_page\' );
您可以根据需要为函数命名—需要注意的关键是挂钩如何匹配
action 参数，带后缀
admin_action_.
