这就是我最终解决这个问题的原因。最初，我将此代码用于链接以删除单个帖子：

<?php if( !(get_post_status() == \'trash\') ) : ?>
<a class="delete-post" onclick="return confirm(\'Are you sure you wish to delete post: <?php echo get_the_title() ?>?\')"href="<?php echo get_delete_post_link( get_the_ID() ); ?>">Delete</a>
<?php endif; ?>

在检查用户是否已登录以及该用户是否是本文作者之后。这并没有像我在原来的帖子中提到的那样奏效。

相反，我使用了一个简单的删除按钮（与上面提到的检查相同）：

<form class="delete-post" action="<?php bloginfo(\'url\'); ?>/edit-post" method="post"> 
    <input id="post_id" type="hidden" name="postid" value="<?php the_ID(); ?>" /> 
    <input type="submit" value="Delete" />
</form>

这个jQuery脚本用于进行ajax调用，该调用将运行我的php脚本：

jQuery(document).ready(function($){  
    $(\'.delete-post\').bind(\'click\', function(e){

        e.preventDefault();

        var post_id;
        post_id = $("#post_id").val();
        var data = {};
        var obj = {data: data}; 
        data[\'post_id\'] = post_id;

        alert(\'Are you sure you wish to delete this post?\');
        process_delete_post();

        function process_delete_post() {
            jQuery.ajax({
                type: "POST",
                url: run_delete_post.ajaxurl,
                data: ({
                    post_id : data[\'post_id\'],
                    action : \'run_delete_post_script\',
                }),
                success: function() {
                     location.href = "";
                },

                error: function(jqXHR, exception) {
                    if (jqXHR.status === 0) {
                        alert(\'Not connect.\\n Verify Network.\');
                    } else if (jqXHR.status == 404) {
                        alert(\'Requested page not found. [404]\');
                    } else if (jqXHR.status == 500) {
                        alert(\'Internal Server Error [500].\');
                    } else if (exception === \'parsererror\') {
                        alert(\'Requested JSON parse failed.\');
                    } else if (exception === \'timeout\') {
                        alert(\'Time out error.\');
                    } else if (exception === \'abort\') {
                        alert(\'Ajax request aborted.\');
                    } else {
                        alert(\'Uncaught Error.\\n\' + jqXHR.responseText);
                    }
                }

            });
        }   

    }); 

}); 

在我的功能中。php文件，我设置了ajax调用：

function mytheme_delete_post() {
    if ( is_page_template( \'edit-delete-posts.php\' ) ) {
        wp_enqueue_script( \'process-delete-post\', get_template_directory_uri().\'/js/process-delete-post.js\', array(\'jquery\'), true);
        wp_localize_script( \'process-delete-post\', \'run_delete_post\', array( \'ajaxurl\' => admin_url( \'admin-ajax.php\' ) ) );
        }
}
add_action(\'template_redirect\', \'mytheme_delete_post\');

$dirName = dirname(__FILE__);
$baseName = basename(realpath($dirName));
require_once ("$dirName/functions_custom.php");

add_action("wp_ajax_run_delete_post_script", "run_delete_post_script");     

然后，用实际的php脚本在my functions\\u custom中删除帖子。php文件：

function run_delete_post_script() {
    // Test for current user
    mytheme_get_current_user();

    //Get the data from the submit page and convert to php variables
    foreach ($_POST as $field => $value) {
        if (isset($_POST[$field])) {
            $$field = $value;
        }
    }
    wp_delete_post( $post_id );
}
