Question

我在Wordpress中有一个php函数，该函数自动将用户的名字和姓氏分配给帖子标题。这是在前端。但是，在后端中，当管理员编辑相同的帖子时，不应使用管理员的值覆盖该帖子。

如何对此进行修改，以使A）不在后端运行，即仅在前端运行，或者B）仅在用户不是管理员的情况下执行？任何帮助深表感谢。谢谢大家。

function wpse67262_change_title( $data ) {
if( 'gd_place' != $data['post_type'] )
    return $data;
$user = wp_get_current_user();
$data['post_title'] = $user->first_name . ' ' . $user->last_name;
return $data;
}
add_filter( 'wp_insert_post_data', 'wpse67262_change_title' );

Answer 1

您可以尝试禁用帖子标题

jQuery(document).ready(function() {
    post_status = /* your post status here */
    if( post_status != "auto-draft" ) {
    jQuery( "#title" ).attr( 'disabled', true );
});

Answer 2

您可以通过以下方式检查当前用户是否为管理员：

if ( current_user_can( 'administrator' ) ) {
    /* A user with admin privileges */
} else {
    /* A user without admin privileges */
}

current_user_can函数文档：https://codex.wordpress.org/Function_Reference/current_user_can

我在这里在您的函数中为您写了一些评论-但一切都应该有意义

function wpse67262_change_title( $data ) {
    if( 'gd_place' != $data['post_type'] ){
        return $data;
        //This is for your pos type only?
    }

    $user = wp_get_current_user(); 
    if(!is_admin() && !current_user_can('administrator')){
        //So this makes sure, that the following does NOT run in the backend and also takes the admin role into account 
        $data['post_title'] = $user->first_name . ' ' . $user->last_name;
        return $data;
    } else {
        //one of the conditions failed - So do nothing new
        return $data;
    }


}
add_filter( 'wp_insert_post_data', 'wpse67262_change_title' );

更清洁的功能可能是：

function wpse67262_change_title( $data ) {

    if(!is_admin() && !current_user_can('administrator') && 'gd_place' == $data['post_type']){
        //So this makes sure, that the following does NOT run in the backend and also takes the admin role into account, and checks the post type 
        $user = wp_get_current_user(); 
        $data['post_title'] = $user->first_name . ' ' . $user->last_name;
        return $data;
    } else {
        //one of the conditions failed - So do nothing new
        return $data;
    }


}
add_filter( 'wp_insert_post_data', 'wpse67262_change_title' );

仅当用户不是管理员时，WordPress中的php函数才适用
