【问题描述】：
当用户发布我制作的表单时，我出现了白屏死机。有趣的是，当我作为网站的管理员（该网站使用 wordpress 运行）在表单中发布相同的数据并提交时，它可以工作，但是当用户这样做时，它会出现白屏并提供帮助。以下是我正在使用的表单数据和其他一些代码。
这是表单部分的代码（我知道这不是很好的代码，我还在学习）
function bio_form(){
global $wpdb, $current_user;
//get current user info
get_currentuserinfo();
$yes = $_GET['submitted'];
//check log in
if(!is_user_logged_in()) {
//user isnt logged in
echo "You must be logged in to use this form";
//show login form
if (!(current_user_can('level_0'))){
echo "<h2>Login</h2>";
echo "<form action=" . get_option('home') . "/wp-login.php method='post' enctype='multipart/form-data'>";
echo "<input type='text' name='log' id='log' value='" . wp_specialchars(stripslashes($user_login), 1) . "' size='20' />";
echo "<input type='password' name='pwd' id='pwd' size='20' />";
echo "<input type='submit' name='submit' value='Send' class='button' />";
echo "<p>";
echo "<label for='rememberme'><input name='rememberme' id='rememberme' type='checkbox' checked='checked' value='forever' /> Remember me</label>";
echo "<input type='hidden' name='redirect_to' value=" . $_SERVER['REQUEST_URI'] . " />";
echo "</p>";
echo "</form>";
echo "<a href='" . get_option('home') . "/wp-login.php?action=lostpassword'>Recover password</a>";
//add register link
} else {
echo "<h2>Logout</h2>";

如果有人可以在这里提供帮助，那就太好了。我想知道它是否与发布数据有关，例如，这是提交表单时的 url 示例。

它真的很长，里面有很多东西，我想知道这是否是问题所在，尽管正如我所说，当我使用上述相同的字符串时，当我以管理员身份登录时它对我来说很好。
P.S 抱歉，代码块中的代码格式不正确。
【问题讨论】：
-
首先，做一个“查看源代码”以查看是否有输出，但它只是呈现一个空白页面。其次，您需要查看 Web 服务器的错误日志。那里可能有一条消息告诉您该页面中的一些问题。
-
我查看了错误日志，什么也没有。而且没有出处，相信跟查询中的%27等代码有关
-
我通过更改表单的方法来修复它
