如何正确编码/解码通过POST发送的变音符号 [英] How to properly encode/decode diacritics sent through POST

问题描述

这是我的问题，让我头疼了一阵子。我需要我的网络应用程序来正确处理任何东欧变音符号（主要是ăĂÎşşŞţŢŢ）。数据库正确处理它们，并且php脚本正确处理它们（所有php脚本使用utf-8编码），但是在处理表单时有问题。

例如，将以下内容插入到数据库中，它被正确处理，字符编码正确，保存正确，正确显示：

  $ insert_value = htmlentities（'ăĂîÎşŞţŢâ'，ENT_COMPAT，UTF-8）; 
  

但是，如果在文本/文本区域输入中输入相同的字符串，并使用POST发送：

  $ insert_value = htmlentities（$ _ POST ['test_string']，ENT_COMPAT，UTF-8）; 
  

这将返回一个空字符串。

我检查了脚本使用Firefox接收到的POST，而不是'şŞţŢ'字符，我得到了奇怪的符号（ºªþÞ），所以我猜这就是为什么htmlentities返回空白。 >

我尝试在表单上设置enctype以进行多部分/表单数据，并且似乎正确地发送它，但是然后将htmlentities应用到它仍然以某种方式拧紧它（例如，如果 $ _ POST ['ta'] =ăĂîÎşŞţŢâ,htmlentities（$ _ POST ['ta']，ENT_COMPAT，UTF-8）返回$ kappa; ）

编辑：非常感谢欺骗，该链接帮助我处理我的Web应用程序的编码，而无需任何htmlentities调用。我推荐这篇文章给任何人在php，html和数据库之间玩弄变音的麻烦。

不要对进入数据库的数据进行HTML编码，处理Unicode前端到Web应用程序。有一些这样的问题，前面提到的文章是最大的。

Here's my problem that has been giving me a headache for a while. I need my web application to properly handle any eastern european diacritics (mostly ă Ă î Î ş Ş ţ Ţ â Â). The database handles them properly, and the php scripts handle them properly (all php scripts use utf-8 encoding), however there is a problem when handling forms.

For example, insert the following to the database, it's handled correctly, characters are encoded properly, saved properly, displayed properly:

$insert_value = htmlentities('ă Ă î Î ş Ş ţ Ţ â Â',ENT_COMPAT, "UTF-8");

If, however, I type the same string in a text/textarea input and use POST to send it:

$insert_value = htmlentities($_POST['test_string'],ENT_COMPAT, "UTF-8");    

this will return an empty string.

I checked the the POST that the script is receiving with Firefox and instead of the 'ş Ş ţ Ţ' characters I get weird symbols(º ª þ Þ), so I'm guessing that's why htmlentities is returning empty.

I tried setting enctype on the form to multipart/form-data and it seems to send it properly but then applying htmlentities to it still somehow screws it up (for example if $_POST['ta'] = ăĂîÎşŞţŢâÂ, htmlentities($_POST['ta'],ENT_COMPAT, "UTF-8") returns $kappa;)

Edit: many thanks to deceze, that link helped me handle the encoding for my web application without any htmlentities calls. I recommend that article to anyone having trouble with juggling diacritics between php, html, and databases.

Don't HTML-encode data that goes into the database, Handle Unicode Front To Back In A Web App. There are a number of gotchas for doing that, the aforelinked article goes through the biggest ones.
