Php mysql用户评分和评论系统

Question

我有以下给定的星级评分脚本。它工作正常，但是当我想在处理文件中使用$ _GET变量时，它并没有采用它。

另外我想使用这个脚本的意见，但我不能在tuto-star-rating.php使用$ _POST或$ _GET。

我可以得到$_GET['sid']在index.php但我不能在tuto-start-rating.php得到sid。这个tuto-start-rating.php是通过JS调用的。

在index.php文件的URL是index.php?sid=1

在tuto-star-rating.php我想用$ _GET保存餐厅ID，但无法做到这一点。我尝试如下，但它不接受它仅接受将直接作为你可以在下面的文件代码中看到的数字：

$getRest = mysql_real_escape_string($_GET['sid']); 
$query = $bdd->execute('INSERT INTO rest_rating (sr_id, media, rate, ip, user) 
VALUES ('.$getRest.', '.$mediaId.', "'.$rate.'", "'.$ipaddress.'", "'.$user.'")'); // We insert the new rate 

我需要帮助使用不同的形式与此代码评论系统集成或整合在一起。

的index.php

    include('comment/dbClass.php');

从your comment，

我可以在index.php中获得sid，但是我无法在tuto-start-rating.php中获得sid。该政党成员 - 开始 - rating.php通过JS称为

既然你包括JavaScript作为外部文件，你不能用/你政党成员星级rating.js访问诸如$_GET['sid'] PHP变量文件。您需要更改index.php和tuto-star-rating。JS文件按以下方式，

的index.php

你包括政党成员星级rating.js文件中的index.php页面只是之前，添加此线下方，

<script>var sid = "<?php echo $_GET['sid']; ?>";</script> 
// include your tuto-star-rating.js file 

政党成员星级rating.js

您需要更改以下列方式你的AJAX请求，

function rateMedia(mediaId, rate, numStar) { 

    // your code 

    $.ajax({ 
     type: 'POST', 
     url: 'comment/tuto-star-rating.php?sid=' + sid, 

     // your code 
    }); 
} 

通过这种方式，您可以使用$_GET 超全局中政党成员星级rating.php页面访问SID，像这样：

$getRest = mysql_real_escape_string($_GET['sid']); 

---

旁注：不要使用mysql_*功能，它们被弃用的PHP 5.5，并在PHP 7.0中完全删除。改为使用mysqli或pdo。 And this is why you shouldn't use mysql_* functions。

Answer 2

为了解决$ _GET [ 'SID']首先确保SID正在通过URL （例如：HTTP：//youdomainname.com/ SID = 1）。 然后，通过SID作为参数传递给starBar功能，你可以看到波纹管：

function starBar($numStar, $mediaId, $starWidth, $sid) { 
    // your code here 
} 

当你调用该函数（在最后的index.php文件）唐“别忘了通过新的参数：

echo starBar(5, 59, 16, $_GET['sid']);
