我制作了一个名为esrnumber的额外自定义字段。我onUserBeforeSave()在插件中的 php 文件中添加了一个函数。这应该从我的自定义字段中获取 esrnumber 以及从注册表单中获取名称，检查数据库，如果它们匹配则返回 true。从而允许用户注册。
问题是我似乎无法将表单中的字段值获取到这个 php 脚本中。下面是我的代码。
function onUserBeforeSave($user, $isnew, $new){
//sql code removed for example
$foundesr = false;
if ($_SERVER['REQUEST_METHOD'] == 'GET' && isset($_GET['esrnumber'])) {
$test = $_GET['esrnumber'];
} else if ($_SERVER['REQUEST_METHOD'] == 'POST' && isset($_POST['esrnumber'])) {
$test = $_POST['esrnumber'];
} else {
$test = "booo";
}
if($foundesr == false){
JError::raiseWarning(1000, JText::_('There is a problem with your ESR number, ' . JRequest::getVar('username') . JRequest::getVar('esrnumber') . JRequest::getVar('jform_username') . $test . 'it does not match that name in our records.'));
return false;
}
return true;
}
正如您所看到的，其中大部分是不必要的，我刚刚尝试了几种不同的方法来从注册表单字段中检索值，它们都返回空值。我哪里错了？我怎样才能简单地从我的表单中获取值到这个方法中？
这是 Joomla 为表单生成的HTML代码（asfaik 这是所有默认内容）

我个人从未调用过我创建的新方法，我只是创建了该方法，而 Joomla 似乎在提交表单时会自动调用它。
干杯。
