我在团队页面中显示的用户配置文件中有自定义字段。上面写着“主任”、“研究员”、“毕业生”、“实习生”等。添加新团队成员时，可以从带有选项的选择框中进行选择。

现在，页面按创建日期顺序显示用户，但我需要按层次顺序显示他们（首先是所有董事，然后是研究人员，然后是毕业生，等等）。

配置文件的新字段位于函数中。php，代码如下：

<!-- ROLE -->

<?php $role = get_user_meta($user->ID, \'member_role\', true); ?>

<table class="form-table">

<tr>
    <th><label for="member_role">Lab Role</label></th>
    <td>
        <select name="member_role" id="member_role">
        <option value="" <?php if($role == \'\'){echo(\'selected="selected"\');}?>>Choose role</option>
        <option value="principal-investigator" <?php if($role == \'principal-investigator\'){echo(\'selected="selected"\');}?>>Principal Investigator</option>
        <option value="labmanager" <?php if($role == \'labmanager\'){echo(\'selected="selected"\');}?>>Lab Manager</option>
        <option value="administrativeassistant" <?php if($role == \'administrativeassistant\'){echo(\'selected="selected"\');}?>>Administrative Assistant</option>
        <option value="postdoc" <?php if($role == \'postdoc\'){echo(\'selected="selected"\');}?>>Postdoctoral Fellow</option>
        <option value="gradstudent" <?php if($role == \'gradstudent\'){echo(\'selected="selected"\');}?>>Graduate Student</option>
        <option value="researchtech" <?php if($role == \'researchtech\'){echo(\'selected="selected"\');}?>>Research Technician</option>
        <option value="undergradstudent" <?php if($role == \'undergradstudent\'){echo(\'selected="selected"\');}?>>Undergraduate Student</option>
        <option value="labsupport" <?php if($role == \'labsupport\'){echo(\'selected="selected"\');}?>>Lab Support</option>
        </select>
        <br />
        <span class="description">Please select your role at the lab.</span>
    </td>
