【问题描述】：
我正在尝试在 Wordpress 中构建一个表单并将表单中的数据插入到数据库中。当我使用硬编码数据时，它可以正常工作，但是如果我将其更改为使用表单中的变量，则根本不会插入数据。任何帮助将非常感激。
<?php
/*
Template Name: My Form Page
*/
?>
<?php
//user posted variables
$name = $_POST['message_name'];
$email = $_POST['message_email'];
$message = $_POST['message_text'];
$human = $_POST['message_human'];
$selectedFood = 'None';
if(isset($_POST['selectedFood']) && is_array($_POST['selectedFood']) && count($_POST['selectedFood']) > 0){
$selectedFood = implode(', ', $_POST['selectedFood']);
}
//establish connection
if(empty($errorMessage))
{
$db = mysql_connect("localhost","xxx","xxx");
if(!$db) die("Error connecting to MySQL database.");
mysql_select_db("xxx" ,$db);
$sql = "INSERT INTO wp_picnic_guest (name, yourname, moviename) VALUES ($name, $email, $message)";
mysql_query($sql);
}
function PrepSQL($value)
{
// Stripslashes
if(get_magic_quotes_gpc())
{
$value = stripslashes($value);
}
// Quote
$value = "'" . mysql_real_escape_string($value) . "'";
return($value);
}
//response generation function
$response = "";
//function to generate response
function my_contact_form_generate_response($type, $message){
global $response;
if($type == "success") $response = "<div class='success'>{$message}</div>";
else $response = "<div class='error'>{$message}</div>";
}
//response messages
$not_human = "Human verification incorrect.";
$missing_content = "Please supply all information.";
$email_invalid = "Email Address Invalid.";
$message_unsent = "Message was not sent. Try Again.";
$message_sent = "Thanks! Your message has been sent.";
//php mailer variables
$to = get_option('admin_email');
$subject = "Picnic Food from ".get_bloginfo('name');
$body = "From: $name\n E-Mail: $email\n Message: $message\n Selected Food:\n $selectedFood";
$headers = 'From: '. $email . "\r\n" .
'Reply-To: ' . $email . "\r\n";
if(!$human == 0){
if($human != 2) my_contact_form_generate_response("error", $not_human); //not human!
