与号进去，PHP [英] Ampersand in GET, PHP

问题描述

我有一个简单的表单，生成一个新的照片库，发送标题和到MySQL的描述，将用户重定向到一个页面，在这里他们可以上传照片。

I have a simple form that generates a new photo gallery, sending the title and a description to MySQL and redirecting the user to a page where they can upload photos.

一切正常，直到符号输入公式。该信息是从一个jQuery模态对话框到PHP页面，然后提交条目发送到数据库。阿贾克斯成功完成后，用户被发送到上传页面用GET URL来告诉它上传到相册什么的页面 -

Everything worked fine until the ampersand entered the equation. The information is sent from a jQuery modal dialog to a PHP page which then submits the entry to the database. After Ajax completes successfully, the user is sent to the upload page with a GET URL to tell the page what album it is uploading to --

$.ajax ({
    type: "POST",
    url: "../../includes/forms/add_gallery.php",
    data: $("#addGallery form").serialize(),
    success: function() {
        $("#addGallery").dialog('close');
        window.location.href = 'display_album.php?album=' + title;
    }
});

如果标题有一个符号，在上传页面上的标题字段不正确显示。有没有一种方式来逃避符号的GET？

If the title has an ampersand, the Title field on the upload page does not display properly. Is there a way to escape ampersand for GET?

感谢

推荐答案

在一般你要 URL-CN $ C $ Ç任何事情，当你把它们作为你的网址的一部分，是不是完全字母。

In general you'll want to URL-encode anything that isn't completely alphanumerical when you pass them as parts of your URLs.

在URL编码，＆安培; 被替换％26 （因为0X26 = 38 =的ASCII $ C $了C ＆安培; ）

In URL-encoding, & is replaced with %26 (because 0x26 = 38 = the ASCII code of &).

要做到这一点在Javascript中，你可以使用函数<一href="http://www.w3schools.com/jsref/jsref_en$c$cURIComponent.asp"><$c$c>en$c$cURIComponent:

To do this in Javascript, you can use the function encodeURIComponent:

$.ajax ({
    type: "POST",
    url: "../../includes/forms/add_gallery.php",
    data: $("#addGallery form").serialize(),
    success: function() {
        $("#addGallery").dialog('close');
        window.location.href = 'display_album.php?album=' + encodeURIComponent(title);
    }
});

请注意， 逃跑 具有<缺点code> + 不是连接codeD，并且将去codeD服务器端作为一个空间，因此应避免（的来源）。

Note that escape has the disadvantage that + is not encoded, and will be decoded serverside as a space, and thus should be avoided (source).

如果你想做到这一点的服务器端在PHP层，则需要使用该功能的 urlen code 。

If you wish to do this serverside at the PHP level, you'll need to use the function urlencode.
