当一个用户（又名我）点击按钮时，我试图插入一篇帖子（这个按钮位于管理仪表板上的元框内）。这没有发生，我也不知道为什么。当我将函数的内容直接放入php页面时，就会插入帖子。但在函数内部，代码似乎什么都没有做。

我的PHP

 add_action(\'wp_dashboard_setup\', \'schedule_synopsissen_setup\');

 function schedule_synopsissen_setup() {
     wp_add_dashboard_widget(\'schedule-synopsissen\', \'Synopsissen maken\', \'schedule_synopsissen_content\');
 }

 function schedule_synopsissen_content() {
     ?><form action="index.php" method="post">
         <input type="submit" name="synopis_schedule" value="Synopsis maken" />
     </form>
     <?php
     if($_SERVER[\'REQUEST_METHOD\'] == "POST" and isset($_POST[\'synopis_schedule\'])) { schedule_synopsissen(); echo \'<br>De synposis werd aangemaakt!\'; }
 }

 function schedule_synopsissen() {
