假设您正在谈论一个自定义用户role 名为“摄影师”，我相信这样的东西应该会增加delete_posts 该角色的能力。

function add_delete_cap_to_photog_role() {
    $role = get_role( \'photographer\' );

    $role->add_cap( \'delete_posts\' );
}
add_action( \'admin_init\', \'add_delete_cap_to_photog_role\');

为角色添加上限后，要解决其余问题，您可以

保持blockusers_init 和沟渠get_delete_post_link 对于ajax删除blockusers_init 函数并执行条件重定向我会对每一个都给出一些想法。我喜欢开沟get_delete_post_link 在这种情况下。

Several steps below, so be aware the code is provided as a guide only. Rewrite and rename things as needed.

沟渠get_delete_post_link AJAX删除替换get_delete_post_link 用这样的方式排队：

<?php if( current_user_can( \'delete_post\' ) ) : ?>
    <a href="#" data-id="<?php the_ID() ?>" data-nonce="<?php echo wp_create_nonce(\'ajax_delete_post_nonce\') ?>" class="delete-post">delete</a>
<?php endif ?>

Enqueue some JS

在文件中：函数。php

function delete_post_ajax() {
    wp_enqueue_script(  \'delete_ajax\', get_template_directory_uri() . \'/js/my_script.js\', array( \'jquery\' ), \'1.0.0\', true );
    wp_localize_script( \'delete_ajax\', \'TheAjax\', array( \'ajaxurl\' => admin_url( \'admin-ajax.php\' ) ) );
}

add_action( \'wp_enqueue_scripts\', \'delete_post_ajax\' );

onClick to pass data to delete method

在文件：/js/my\\u脚本中。js公司

jQuery( document ).ready( function($) {
    $(document).on( \'click\', \'.delete-post\', function() {
        var id = $(this).data(\'id\');
        var nonce = $(this).data(\'nonce\');
        var post = $(this).parents(\'.post:first\');
        $.ajax({
            type: \'post\',
            url: TheAjax.ajaxurl,
            data: {
                action: \'wpse_ajax_delete_post\',
                nonce: nonce,
                id: id
            },
            success: function( result ) {
                if( result == \'success\' ) {
                    post.fadeOut( function(){
                        post.remove();
                    });
                }
            }
        })
        return false;
    })
})

the delete method

文件中：函数。php（我们需要的钩子只是“wp_ajax“在action 在js文件中）

add_action( \'wp_ajax_wpse_ajax_delete_post\', \'wpse_ajax_delete_post_func\' );
function wpse_ajax_delete_post_func(){

    $permission = check_ajax_referer( \'ajax_delete_post_nonce\', \'nonce\', false );
    if( $permission == false ) {
        echo \'error\';
    }
    else {
        wp_delete_post( $_REQUEST[\'id\'] );
        echo \'success\';
    }

    die();

}

要通过传递uri参数执行上述操作：

更改我们调出的位置get_delete_posts_link 为此：

<?php if( current_user_can( \'delete_post\' ) ) : ?>
    <?php $nonce = wp_create_nonce(\'ajax_delete_post_nonce\') ?>
    <a href="<?php echo admin_url( \'admin-ajax.php?action=wpse_ajax_delete_post&id=\' . get_the_ID() . \'&nonce=\' . $nonce ) ?>" data-id="<?php the_ID() ?>" data-nonce="<?php echo $nonce ?>" class="delete-post">delete</a>
<?php endif ?>

沟渠blockusers_init （又名条件重定向）如果用户没有manage_options cap，这是一个管理员角色。但首先，它会使用一些css伪隐藏内容并向用户添加消息：

The CSS bit

在文件中：函数。php

add_action(\'admin_head\', \'hide_admin_via_css\');
function hide_admin_via_css() {
    if (!current_user_can( \'manage_options\' )) {
        echo \'<style>body * {visibility:hidden !important;} body:before {content:"Give it a second...";}
\';
    }
}

Enqueueing the JS file

在文件中：函数。php

function my_enqueue( $hook ) {
    if (!current_user_can( \'manage_options\' )) {
        wp_enqueue_script( \'my_custom_script\', get_template_directory_uri() \'/js/block-admin.js\' );
    }
}
add_action(\'admin_enqueue_scripts\', \'my_enqueue\');

Set the JS to just immediately redirect

文件：theme\\u root/js/block admin。js公司

window.location.href = "/";

OR a timed redirect

setTimeout(function () {
   window.location.href = "/";
}, 2000);
