我已经在wordpress上构建了一个PHP联系人表单，该表单根据用户所选择的区域来重定向用户。
我已经使用'www.google.com'作为测试URL。
但是，表单将重定向到我基于WP构建的自定义主题页面。
我要去哪里错了？
请在下面找到代码：
<html>
<head>
<title> Meal Planner </title>
</head>
<body>
<?php
function checkregion($Region)
{
SWITCH ($Region)
{
case "North":
header('location:https://www.google.com/');
break;
case "South":
header('location:https://www.google.com/');
break;
case "East":
header('location:https://www.google.com/');
break;
case "West":
header('location: https://www.google.com/');
break;
}
}
checkregion($Region);
?>
<form action="<?=get_template_directory_uri() ?>/custompage1.php " method="POST">
<p>Name</p> <input type="text" name="name">
<p>Email</p> <input type="text" name="email">
<p>Phone</p> <input type="text" name="phone">
<p>Dropdown Box</p>
<select name="Region" size="1">
<option value="North">North</option>
<option value="South">South</option>
<option value="East">East</option>
<option value="West">West</option>
</select>
<br />
<input type="submit" value="SUBMIT"><input type="reset" value="CLEAR">
</form>
</body>
</html>
要在与表单相同的页面上调用checkRegion函数，除非该页面为customepage1.php，否则您需要从表单中删除操作并将POST变量Region作为输入参数传递给函数。调用header函数时，应在生成任何HTML内容之前调用此函数（除非启用了output buffering）
<?php
function checkregion( $Region ) {
switch ($Region) {
case 'North': header('Location: https://www.google.com/'); break;
case 'South': header('Location: https://www.google.com/'); break;
case 'East': header('Location: https://www.google.com/'); break;
case 'West': header('Location: https://www.google.com/'); break;
}
}
if( !empty( $_POST['Region'] ) ) checkregion( $_POST['Region'] );
?>
