PHP不处理某些表单字段
我最近创建了一个PHP / MySQL评论系统，它直到几个小时前都在运行（代码中根本没有任何改变）。 当我告诉提交表单代码以回显查询时，它显示缺少用于评论文本和日期的区域。 我不明白为什么。 这是我的代码：
mysql_connect("localhost","commentUser","password");
mysql_select_db("comments");
$name = mysql_real_escape_string($_POST['name']);
$postID = mysql_real_escape_string($_POST['postId']);
if(!is_numeric($postID))
exit();
$email = mysql_real_escape_string($_POST['email']);
$comment = strip_tags(mysql_real_escape_string($_POST['comment']), '');
$date = mysql_real_escape_string($_POST['date']);
if($email == '' || $comment = '' || $date = '')
exit();
$query = "INSERT INTO comments (PostID,Name,Email,Text,Date) VALUES($postID, '$name', '$email', '$comment', '$date')";
mysql_query($query) or die(mysql_error());
mysql_close();
echo "
window.location = "snippet.php?id=$postID";
";
您将空字符串分配给$comment ，将$date分配给=
if($email == '' || $comment = '' || $date = '')
exit();
// Should use `==` for all three:
if($email == '' || $comment == '' || $date == '')
exit();
