复选框的顺序顺序选择的PHP

问题描述

目前，我的HTML代码是：

 < form id =querymethod =postaction =search.php> 
< input type =checkboxname =col_list []value =host> host< / input> 
< input type =checkboxname =col_list []value =atom_name> atom_name< / input> 
 ... 
< input type =submit> / input> 
< / form> 
  

  $ columns = $ _POST [col_list]; 
  

$

解决方案

有什么办法可以得到被选中的复选框的顺序？

您需要添加一些javascript才能获取该信息。

 < input type =hidden =order/><！ - 在表单内 - > 
  

是使用jQuery的例子：

  $（'[name * =col_list]' 
 if（$（this）.prop（'checked'））{
 $（'[name =order]' .val（）+'，'+ $（this）.val（））
} 
}）; 
  

这应该很好地与一个警告：

如果用户取消选中然后re-ckecks一个复选框，它将被添加到

 ，请执行以下操作： host，atom_name

修正了一些拼写错误，这里有一个

At the moment, my html code is:

<form id = "query" method = "post" action = "search.php">
     <input type = "checkbox" name = "col_list[]" value = "host">host</input>
     <input type = "checkbox" name = "col_list[]" value = "atom_name>atom_name</input>
     …
     <input type = "submit">Submit</input>
</form>

And my php code:

 $columns = $_POST["col_list"];

Is there any way is which I can get the sequence in which the checkboxes where checked?

解决方案

you'd need to add a some javascript to get that info.

<input type="hidden" name="order"/> <!-- goes inside the form -->

Here is an examply using jQuery:

$('[name*="col_list"]').change(function(){
   if ($(this).prop('checked')){
       $('[name="order"]').val($('[name="order"]').val()+','+$(this).val())
    }
});

This should work fairly well with one caveat:

If the user un-checks then re-ckecks a checkbox it will be added to order twice.

order should result in something like:

,host,atom_name
