Example analysis of the use method of hook in thinkPHP

This article describes how to use hooks in thinkPHP. Share it for your reference, as follows:

As mentioned earlierTwo configuration call methods for hooks in thinkPHP, let’s further analyze the use of hooks.

1 Create hook behavior:

We define our own tag bits directlyThink\BehaviorsIn it, it can also be placed in the application directory, for example, under the Home module, create a new Behaviors folder and create a new Behaviors folder in the folder

Tag name+

Note: The reason for the need to bring Behavior is shown in the code:

static public function exec($name, $tag,&$params=NULL) {
    if('Behavior' == substr($name,-8) ){
      // The behavior extension must be run entry method      $tag  =  'run';
    }
    $addon  = new $name();
    return $addon->$tag($params);
}

Here I've customized tag name is My

namespace Behavior;
use Think\Behavior;
class MyBehavior extends Behavior
{
  public function run(&$arg){
    echo 'Thinkphp'.$arg['name'].'Function,'.$arg['value'].'middle...';
  }
}

Pay attention to the upper and lower case of class names

2 Add the hook into the hook set

Method 1 (Manual Registration): Add directly to the controller:

Hook::add('addd','Behavior\\adBehavior'); 

Method 2 (automatic registration):

Inside the Conf folder (full pathD:\think\application\Home\Conf\, of course this is my situation):

return array(
//'action_begin'=>array('Home\\Behaviors\\test','Home\\Behaviors\\test'),
 //A tag bit can have multiple behaviors, just use an array. // If it is version 3.2.1, it needs to be changed to // 'action_begin'=>array('Home\\Behaviors\\testBehavior','Home\\Behaviors\\testBehavior'),
 'my'=>array('Behaviors\\MyBehavior')
);

3 Add listening: (I just use the template to listen directly)

If you cannot find the hook method here, pleaseThinkPHP/Common/Added in (of course, it can also be found in other public files):

function hook($hook,$params= array()){
  \Think\Hook::listen($hook,$params);
}

Finally, use it in the template:

{:hook('my', array('name'=>'hook','value'=>'study'))}

I hope that the description in this article will be helpful to everyone's PHP programming based on the ThinkPHP framework.
