我需要一些关于我的阻止用户脚本的帮助。我试图让它插入值，然后将被阻止的列从“0”设置为“1”。

它可以很好地插入值，我的意思是它在没有问题的情况下插入了 user_id 和 blocked_id，但是当我尝试将其从“0”设置为“1”时，它会导致我的语法错误。

谁能告诉我我哪里出错了，谢谢。

代码：

<?php

require_once('includes/session.php');
require_once('includes/functions.php');
require('includes/_config/connection.php');

session_start();

    confirm_logged_in();

    if (isset ($_GET['to'])) {
    $user_to_id = $_GET['to'];


}


if (!isset($_GET['to']))
    exit('No user specified.');

$user_id = $_GET['to'];




$result1 = mysql_query("INSERT INTO ptb_block_user (user_id, blocked_id) VALUES (".$_SESSION['user_id'].", ".$user_to_id.")")

$result2 = mysql_query("SELECT ptb_block_user SET blocked='1' WHERE id=".$_SESSION['user_id']."") 


or $result3 = mysql_query("DELETE FROM ptb_block_user WHERE user_id = ".$_SESSION['user_id']." AND blocked_id = ".$user_to_id.""); header("Location: {$_SERVER['HTTP_REFERER']}");



if($result1) 
{ 
$_SESSION['message2']="<div class=\"infobox-profile\"><strong>User Blocked</strong> - This user has successfully been blocked. You will no longer be abler to interact with each other's profiles.</div><div class=\"infobox-close\"></div>"; 
header("Location: {$_SERVER['HTTP_REFERER']}");
} 
else 
if($result3) 
{ 
$_SESSION['message2']="<div class=\"infobox-favourites\"><strong>User Unblocked</strong> - This user has successfully been unblocked. You can now interact with each other's profiles.</div><div class=\"infobox-close4\"></div>"; 
header("Location: {$_SERVER['HTTP_REFERER']}");

}
?>

$result2 = mysql_query("UPDATE ptb_block_user SET blocked='1' WHERE id=".$_SESSION['user_id']."")

使用“更新”而不是“选择”来更改行。
