使用php和mysql在注冊表單上檢索電子郵件地址很困難
[英]Difficulty on retrieving email address on a register form with php and mysql
問題描述
您好，我正在嘗試允許用戶成為網站的成員。 我擁有的代碼看起來沒有任何錯誤或任何東西。 當我嘗試注冊為用戶時，會一直顯示我未插入電子郵件地址的錯誤。 電子郵件字段確實存在於數據庫中，我找不到問題。

所有其他領域似乎都很好！ 如果有人對導致問題的原因有任何想法，請告訴我！ 謝謝

編輯：如果您仍然得到相同的結果，則問題出在mysql_real_escape_string，因為它是唯一返回FALSE的函數。
您忘記定義email變量的值。
添加：
$email = $_POST['email'];
在此之上：
$email=str_replace( '/@/', '@', $email );
並在下面添加：
$email = mysql_real_escape_string(strip_tags(stripslashes($email)));

我相信您首先需要獲得職位價值，然后再使用它。 因此，請考慮以下訂單更改：
$email = stripslashes($_POST['email']);
$email=str_replace( '/@/', '@', $email );
$email = strip_tags($email);
$email = mysql_real_escape_string($email);
另外，檢查html文件可能會導致其他錯誤。
<?php $email = isset($_POST['email']) ? $_POST['email'] : ''; ?>
希望這行得通。

使用echo顯示變量的值。 查看$mail在發布時但在應用任何過濾器之前以及在應用每個過濾器之后是什么。 這樣可以將搜索范圍縮小到實際發生錯誤的位置。
