如何使用POST方法从数组中获取值 [英] How to get values from array using POST method

问题描述

如何使用POST方法在另一个页面中获取值？

 < label> 
< input type =radiovalue =1name =jsq [1]checked> 1 
< / label> 
< label> 
< input type =radiovalue =2name =jsq [1]> 2 
< / label>< / br> 
< label> 
< input type =radiovalue =3name =jsq [1]> 3 
< / label> 
< label> 
< input type =radiovalue =4name =jsq [1]> 4 
< / label>< / br> 
< label> 
< input type =radiovalue =5name =jsq [1]> 5 
< / label> 
  

我想获得 jsq [1] 在 myarr [1] 中。我怎么能这样做？

  $ myarr [1] = $ _POST ['jsq [1]']; 
  

解决方案

jsq [1]不只是jsq ...

你几乎在那里，但应该是

  $ myarr [1] = $ _POST ['jsq'] [1]; 
  

使用print_r（$ _ POST）检查这些事情的方法总是一个好主意;或var_dump（$ _ POST）;

How to get value in another page using the POST method?

<label>
    <input type="radio" value = "1" name="jsq[1]" checked>1
</label>
<label>
    <input type="radio" value = "2" name="jsq[1]">2
</label></br>
<label>
    <input type="radio" value = "3" name="jsq[1]">3
</label>
<label>
    <input type="radio" value = "4" name="jsq[1]">4
</label></br>
<label>
    <input type="radio" value = "5" name="jsq[1]">5
</label>

I want to get value of jsq[1] in myarr[1]. How can I do that?

$myarr[1] = $_POST['jsq[1]'];

解决方案

Without going into the question why you're naming them jsq[1] an not just jsq...

you're almost there, but it should be

$myarr[1] = $_POST['jsq'][1];

It's by the way always a good idea to check this king of things using print_r($_POST); or var_dump($_POST);
