具有相同名称的多个textarea和PHP处理 [英] multiple textarea with same name and PHP treatment

问题描述

我有一个动态表格，可以在其中添加和删除textarea.textareas的名称是MyTextarea []

I have a dynamic form in which i can add and remove textarea. The name of textareas is MyTextarea[]

<textarea style="display:inline;" name="MyTextarea[]"></textarea>
<textarea style="display:inline;" name="MyTextarea[]"></textarea>

所以当我想用PHP处理这个textarea时，我正在做一个:

So when I want to treat this textarea with PHP i'm doing a :

echo $_POST['MyTextarea'];

所以 Array 会显示在屏幕上，到目前为止还可以

So a Array is display on the screen, up to now it's ok

所以我做一个 print_r($ _ POST ['MyTextarea']); ，我又得到了相同的结果: Array

So I do a print_r($_POST['MyTextarea']); and I have again the same result : Array

我想知道是否有可能使用 [] 来创建多个具有相同名称的textarea来生成数组.

I want to know if it's possible to have many textarea with same name with [] to generate an array.

如果可能的话，我该怎么办，或者我的代码出了什么问题.

If it's possible how can I do, or what's wrong with my code.

谢谢

推荐答案

您正在使用哪种框架，我很确定在某一时刻某些东西会将您数组转换为字符串，也许是对POST变量进行如下处理:

Which kind of framework are you using, I'm quite sure there is something at one point that is casting you're array into a string, maybe something that apply a treatment on POST variable like this:

foreach ($_POST as $key => $value) {
    if ($value && !$is_magic_quotes_gpc) {
        $_POST["$key"] = addslashes($value);
    }

在这种情况下，您必须删除此功能...要确定我在说什么，可以尝试var_dump($ POST [MyTextarea])=>字符串'Array'(length = 5)(应该是数组)

In this case you've to remove this function... To be sure of what I'm talking about, you can try a var_dump($POST[MyTextarea]) =>string 'Array' (length=5) (should be an array)
