使用用户定义的对顺序传递多个可选参数/值对 [英] Passing multiple optional parameter/value pairs with user defined pair order

问题描述

说用户要在4或5个字段上搜索，好吗？例如。他可能想以名字，电子邮件，手机甚至页码进行搜索。

我想代码的网址如下：

$ b $

value3 / variable1 / value1

（应该有相同的结果）

或以此格式

  site.com/Controller/Method/variable2/value2/variable4/ value4 
  

一些例子可以澄清我的问题：

  site.com/user/search/firstname/John/mobile/123/page/2 
  

或：

  site.com/user/search/lastname/Smith/email/gmail .com 
  

在一句话中：我不想强迫用户使用特定的订单

解决方案

您可以在控制器上使用_remap函数。

  function _remap（$ method，$ params）
 {
 $ map = array 
 for（$ i = 1; $ i  {
 $ map [$ params [$ i-1] = $ params [$ i]; 
} 
 
 if（$ method [0]！='_'&& method_exists（$ this，$ method））
 return $ this-> $ method （$ map）; 
} 
  

如果要在所有控制器中使用它，写一个自定义控制器来扩展CI_controller和这个函数，并让所有的控制器扩展。

Say user is going to search on 4 or 5 fields, ok? eg. he might want to search by firstname, email, mobile or even page number

I want that codeigniter's url be like this:

site.com/Controller/Method/variable1/value1/variable2/value2/variable3/value3

or

site.com/Controller/Method/variable2/value2/variable3/value3/variable1/value1

(that they should have the same result)

or in this format

site.com/Controller/Method/variable2/value2/variable4/value4

some examples to clarify my question:

site.com/user/search/firstname/John/mobile/123/page/2

or:

site.com/user/search/lastname/Smith/email/gmail.com

In one sentence: I don't want to force the user to use a specific order when setting value to parameters.

解决方案

You can use the _remap function on the controller.

function _remap( $method, $params )
{
    $map = array();
    for( $i = 1; $i < count( $params ); $i = $i + 2 )
    {
        $map[$params[$i-1]] = $params[$i];
    }

    if( $method[0] != '_' && method_exists( $this, $method ))
        return $this->$method( $map );
}

If you want to use it across all your controllers, you would be better to write a custom controller to extend CI_controller with this function, and have all your controllers extend that.
