Yii2 GridView Custom Link rewrite actioncolumn

Recently started with Yii2, really great, but there are many shortcomings, today is to say is the GridView link problem.

<?= Gridview::widget ([    $dataProvider,    $searchModel,    ' columns ' = [' email ', [?>    

This is one of the simplest default gridview,gii generated by this, then the problem comes.
If the user management is not a standalone controller, but under the user controller or the site controller, the Actioncolumn default link is view, UPDATE, delete
But I want to be User-view, user-update, user-delete such a link, and then I modified the next, the code is as follows.

<?= gridview::widget ([ " Dataprovider ' +  $dataProvider,  ' filtermodel ' =  $searchModel,  ' columns ' = [[ ' Yii\grid\serialcolumn '],  ' id ',  ' username ',  ' email ', [ ' class ' =  ' Yii\grid\actioncolumn ',  ' template ' =  {User-view} {user-update} {User-delete} ',],],]); ?>             

As a result, everything is gone, why? Then I opened Yii\grid\actioncolumn, read the source, found that he only rendered the default view, update, delete
If a label such as {User-view} does not exist in the button group (buttons[]), the output is empty.

So we have to add a button, and then the code goes like this.

<?= Gridview::widget ([' Dataprovider ' =$dataProvider,' Filtermodel ' =$searchModel,' Columns ' = [[' Class ' =' Yii\grid\serialcolumn '],' ID ',' Username ',' Email ', [' Class ' =' Yii\grid\actioncolumn ',' Template ' =' {User-view} {user-update} {user-delete} ',' Buttons ' = [The following code comes from the Yii\grid\actioncolumn simple modification of the next' User-view ' =function($url,$model,$key) {$options = [' Title ' = Yii::t (' Yii ',' View '),' Aria-label ' = Yii::t (' Yii ',' View '),' Data-pjax ' =' 0 ',];Return Html::a (' <span class= ' Glyphicon glyphicon-eye-open ' ></span> ',$url,$options); },' User-update ' =function($url,$model,$key) {$options = [' Title ' = Yii::t (' Yii ',' Update '),' Aria-label ' = Yii::t (' Yii ',' Update '),' Data-pjax ' =' 0 ',];Return Html::a (' <span class= ' Glyphicon glyphicon-pencil ' ></span> ',$url,$options); },' User-delete ' =function($url,$model,$key) { $options = [ ' title ' = Yii::t ( Yii ',  ' Aria-label ' = Yii::t (  ' Delete '),  ' data-confirm ' = > yii::t ( "Yii",  ' is you sure do want to delete this item? '), 
                                                                           
                                                                             ' Data-method ' + 
                                                                             ' post ',  ' Data-pjax ' = =  ' 0 ',]; return html::a ( ' <span class= "Glyphicon Glyphicon-trash" ></span> ',  $url,  $options);},]], [],]); ?>         
                                                                               

This is OK, but the code is very disgusting, this is not what I want, so I rewrite the yii\grid\actioncolumn to enhance the function of the template.
Similar to ' template ' = ' {url-link:type} ', here the Url-link is your link address, type is the button type, the default Class 3 button is still there.

For example: ' template ' = ' {User-view:view} {user-update:update} {user-del:delete} '
So the address and style can be easily done, of course, you can still customize the button, the same way as above.

<?= Gridview::widget ([' Dataprovider ' =$dataProvider,' Filtermodel ' =$searchModel,' Columns ' = [[' Class ' =' Yii\grid\serialcolumn '],' ID ',' Username ',' Email ', [' Class ' =' Backend\components\actioncolumn ',' Template ' =' {User-view:view} {user-update:update} {User-del:delete} {User-diy-btn:diy} ',' Buttons ' = [Custom Buttons ' diy ' = function  ( $url,  $model,  $key) { $options = [ ' title ' = Yii::t ( ' Aria-label ' + yii::t (  ' View '),  ' data-pjax ' = Span class= "hljs-string" > ' 0 ',]; return html::a ( ' <span class= "Glyphicon Glyphicon-refresh" ></span> ',  $url,  $options);},]], [],]); ?>             

You just add a DIY type button on the OK, if used, you can write directly to backend\components\actioncolumn here.
The effect is as follows.

That's the ideal state, OK, here's the Actioncolumn code.
I put it in the Backend\components directory, you can also put in other places you like, the namespace change is OK.

<?phpNamespaceBackend\components;ClassActioncolumnExtends \Yii\Grid\actioncolumn{Public$template =' {: view} {: update} {:d elete} ';/** * Overrides the label rendering method. *@param mixed $model *@param mixed $key *@param int $index *@return Mixed * *ProtectedfunctionRenderdatacellcontent($model,$key,$index) {Return Preg_replace_callback ('/\\{([^}]+) \\}/',function($matches)Use($model,$key,$index) {List$name,$type) = Explode (‘:‘,$matches [1].‘:‘);Get button name and typeif (!Isset$this->buttons[$type])) {If the type does not exist, the default is view $type =  ' view ';} if ( "= =  $name) {//name is empty, use type name  $name =  $type;}  $url =  $this->createurl ( $name,  $model,  $key,  $index); return call_user_func ( $this->buttons[$ Type],  $url,  $model,  $key);},  $this->template); }}
