我创建了一个PHP程序，它根据HTML联系人表单中输入的用户输入提供定制输出。HTML表单（&H）；PHP输出工作正常。然而，当我试图在WP数据库中保存数据时，我无法看到任何响应。我已经在数据库中创建了“wp\\u mealplanner”表，当我试图通过PHPMYADMIN手动保存数据时，它工作正常。请让我知道我哪里做错了。我没有收到任何错误消息。
请查找以下代码：
<?php
/* Template Name: CustomPageT1 */
$region = $_POST[\'Region\'];
$name = $_POST[\'user_name\'];
$email = $_POST[\'user_email\'];
$phone = $_POST[\'user_phone\'];
$Click_here_to_start_your_download = \'https://mydailysugar.info/wp-
content/uploads/2019/09/Blood-Glucose-Chart-A4-1.pdf\';
switch ($region )
{
case \'North\':
echo "<a href=\'$Click_here_to_start_your_download\'>Click here to start your
download</a>";
die;
case \'South\':
echo "<a href=\'$Click_here_to_start_your_download\'>Click here to start your
download</a>";
die;
case \'East\':
echo "<a href=\'$Click_here_to_start_your_download\'>Click here to start your
download</a>";
die;
case \'West\':
echo "<a href=\'$Click_here_to_start_your_download\'>Click here to start your
download</a>";
die;
}
?>
<?php
if ( isset( $_POST[\'SUBMIT\'] ) )
{
global $wpdb;
$table =\'wp_mealplanner\';
$data = array(\'name\' => $_POST[\'user_name\'],\'email\' =>
$_POST[\'user_email\'],\'phone\' =>
$_POST[\'user_phone\']);
$format = array(\'%s\',\'%s\',\'%d\');
$wpdb->insert( $table, $data, $format );
}
?>
