我有下面给出的星级评分脚本。它工作正常,但是当我想在处理文件中使用$ _GET变量时,它没有接受它。
此外,我想使用此脚本的注释,但我不能在tuto-star-rating.php
中使用$ _POST或$ _GET。
我可以在$_GET['sid']
中获得index.php
,但我无法在tuto-start-rating.php
中获得sid。这个tuto-start-rating.php
是通过JS调用的。
在index.php中,网址为index.php?sid=1
在tuto-star-rating.php
中,我想使用$ _GET保存餐馆ID,但无法执行此操作。我尝试如下,但它不接受它只接受直接放置数字,如下面的文件代码所示:
$getRest = mysql_real_escape_string($_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,使用不同的表单或通过集成相同的代码将注释系统与此代码集成。

来自your comment,
我可以在index.php中获取sid,但我无法在tuto-start-rating.php中获取sid。这个tuto-start-rating.php是通过JS调用的
由于您将JavaScript作为外部文件包含在内,因此您无法在 tuto-star-rating.js 文件中使用/访问PHP变量,例如$_GET['sid']
。您需要以下列方式更改 index.php 和 tuto-star-rating.js 文件,
<强>的index.php 强>
在 index.php 页面中包含 tuto-star-rating.js 文件之前,请在下面添加以下内容,
<script>var sid = "<?php echo $_GET['sid']; ?>";</script>
// include your tuto-star-rating.js file
<强>的tuto星级rating.js 强>
您需要以下列方式更改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
访问 tuto-star-rating.php 页面中的 sid
超全球,像这样:
$getRest = mysql_real_escape_string($_GET['sid']);
旁注:不要使用mysql_*
函数,从PHP 5.5开始不推荐使用它们,并且在PHP 7.0中完全删除它们。请改用mysqli
或pdo
。 And this is why you shouldn't use mysql_*
functions
答案 1 :(得分:0)
要解决$ _GET ['sid']首先确保 sid 传入url (例如:http://youdomainname.com/?sid = 1)。 然后,将 sid 作为参数传递给 starBar 函数,如下所示:
function starBar($numStar, $mediaId, $starWidth, $sid) {
// your code here
}
当您调用该函数时(在 index.php 文件的最后),请不要忘记传递新参数:
echo starBar(5, 59, 16, $_GET['sid']);
