如何仅为特定用户ID显示类

Question

我有下面的代码行，其中包括一个链接，以编辑附件。我只希望某些用户I能够看到这个编辑链接。如何才能使这个链接显示给特定的用户ID？

<div class="details">
            <div class="filename">29982792291_9e1fc5b238_k-1.jpg</div>
            <div class="uploaded">November 9, 2016</div>
            <div class="file-size">1 MB</div>
            <div class="dimensions">2048 × 1365</div>
            <a class="edit-attachment" href="https://www.citynarrative.com/wp-admin/post.php?post=308&amp;action=edit&amp;image-editor" target="_blank">Edit Image</a>
            <button type="button" class="button-link delete-attachment">Delete Permanently</button>
            <div class="compat-meta">
            </div>
        </div>

Answer 1

这取决于您在谈论用户ids时所指的内容。

您可以使用函数edit_post_link( $link, $before, $after, $id, $class );，其中$id是post (或附件) ID

这将只显示链接根据用户的能力。

更多详细信息edit_post_link

$user = wp_get_current_user();
$allowed_roles = array('editor', 'administrator', 'author'); // can be authorized ids 
// but you'll need to replace $user->roles by $user->ID in array_intersect

   if( array_intersect($allowed_roles, $user->roles ) ) {  ?> 
        <div class="details">
            <div class="filename">29982792291_9e1fc5b238_k-1.jpg</div>
            <div class="uploaded">November 9, 2016</div>
            <div class="file-size">1 MB</div>
            <div class="dimensions">2048 × 1365</div>
            <?php echo edit_post_link( __('Edit Image', text-domain), '', '', $id );?>
            <button type="button" class="button-link delete-attachment">Delete Permanently</button>
            <div class="compat-meta">
            </div>
       </div>
   <?php } ?>

您还可以检查用户是否已登录及其角色，以显示您与current_user_can()的链接

试试这段代码

$user_array = array(1, 2 , 3 );  // list of user id
$user_id = get_current_user_id(); // login user id
if (in_array($user_id, $user_array))
{
    ?>
     <div class="details">
            <div class="filename">29982792291_9e1fc5b238_k-1.jpg</div>
            <div class="uploaded">November 9, 2016</div>
            <div class="file-size">1 MB</div>
            <div class="dimensions">2048 × 1365</div>
            <a class="edit-attachment" href="https://www.citynarrative.com/wp-admin/post.php?post=308&amp;action=edit&amp;image-editor" target="_blank">Edit Image</a>
            <button type="button" class="button-link delete-attachment">Delete Permanently</button>
            <div class="compat-meta">
            </div>
        </div>
    <?php
}
