我有一个PHP代码，我正在登录用户名。然后表单来了，然后我需要在db。中保存登录的用户名。
<?PHP
function renderForm($id, $task, $comments, $assignee, $priority, $status, $dataum1, $dataum2, $error )
{
require_once("./include/membersite_config.php");
if(!$fgmembersite->CheckLogin())
{
$fgmembersite->RedirectToURL("login.php");
exit;
}
$user = $fgmembersite->UserFullName();
?>
Html Form来到这里...........
<?php
}
// connect to the database
include('configdb1.php');
// check if the form has been submitted. If it has, process the form and save it to the database
if (isset($_POST['submit']))
{
mysql_query("INSERT INTO comments (comment_id, comments, user) VALUES ('$id', '$text', '$user')")
or die(mysql_error());
?>
但是我声明为登录名的$ user没有插入到db中。请帮忙。
这是我的全部代码：
<?PHP
function renderForm($id, $task, $comments, $assignee, $priority, $status, $dataum1, $dataum2, $error )
{
require_once("./include/membersite_config.php");
if(!$fgmembersite->CheckLogin())
{
$fgmembersite->RedirectToURL("login.php");
exit;
}
?>

尝试此操作（添加"），因为评论可能有特殊的字符：
mysql_query("INSERT INTO comments (comment_id, comments, user) VALUES ('".$id."', '".$text."', '".$user."')") or die(mysql_error());

你有一个名为“提交”的字段吗？ 我的猜测是检查表单是否发布是不正确的。 这就是你永远不会执行查询的原因。
尝试类似：
if (count($_POST) > 0)
// QUERY
