[英]HTML form with spanish characters displayed wrong in MySQL database
So I'm sending data to my MySQL database through a HTML form. 因此,我正在通过HTML表单将数据发送到我的MySQL数据库。
When I send a word with special characters like "ñ" or accents "á, é, í.." and when I check the result in the tables those characters are displayed as "ã±". 当我发送带有特殊字符(如“ñ”或带有重音符号“á,é,í..”)的单词时,当我在表格中检查结果时,这些字符将显示为“ã±”。
I tried pretty much everything: 我几乎尝试了所有事情:
my html form page header has 我的html表单页面标题有
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
The form accepts UTF-8 with <form accept-charset="UTF-8">
表单使用<form accept-charset="UTF-8">
I also added to my action php script: 我还添加了我的动作PHP脚本:
mysql_query("SET NAMES 'utf8'");
mysql_query("SET CHARACTER SET'utf8'");
Then I tried htmlentities
然后我尝试了htmlentities
but all the "ñ" were displayed as ã&
但所有的“ñ”都显示为ã&
My database, tables, and fields are set in utf8_general_ci, also tried utf8_spanish_ci but nothing changed. 我的数据库,表和字段都在utf8_general_ci中设置,也尝试过utf8_spanish_ci,但没有任何更改。
I don't know what else to do, is there anything else I am missing here? 我不知道该怎么办,这里还有什么我想念的吗?
This is the PHP script I'am using: 这是我正在使用的PHP脚本:
<?php

$nombre = '';

Your error is the usage of non-multibyte-safe string functions: 您的错误是使用非多字节安全字符串函数:
$_POST["$field"] = strtolower($_POST["$field"]);
$_POST["$field"] = ucwords($_POST["$field"]);
Use multi-byte string functions instead. 请改用多字节字符串函数 。
Apart from that, your form is vulnerable to SQL injection , something that you need to urgently fix . 除此之外,您的表单容易受到SQL注入的攻击,这是您急需解决的问题 。
just use mysql_real_escape_string() no need to do anything else. 只需使用mysql_real_escape_string()即可,而无需执行其他任何操作。 for example: mysql_real_escape_string($user), mysql_real_escape_string($password)); 例如:mysql_real_escape_string($ user),mysql_real_escape_string($ password));
Why are you so worried about how your data is displayed in phpmyAdmin? 您为什么如此担心您的数据如何在phpmyAdmin中显示? The important thing is that you get the right display when you show them again in a html page. 重要的是,当您在html页面中再次显示它们时,您将获得正确的显示。
you may eventually get correct display in database but then you may have wrong display on html 您最终可能会在数据库中获得正确的显示,但随后在html上可能显示错误
But i think set names do the job, it did for my similar problem even with string 但是我认为集合名称可以完成这项工作,即使使用字符串也可以解决我的类似问题
