This article mainly introduces "yii2 does not show the corresponding button method when there is no permission". In the daily operation, I believe that many people do not show the corresponding button when yii2 does not have permission. The editor consulted all kinds of materials and sorted out a simple and easy-to-use operation method. I hope it will be helpful for everyone to answer the doubt that "yii2 does not show the corresponding button method when there is no authority". Next, please follow the editor to study!

The main solution is that when we do not give the user a role, the corresponding button is not displayed, rather than commenting the code directly in the view.

1: you need to add the following code directly to the Html::a method

Public static function a ($text, $url = null, $options = []) {if ($url! = = null) {$options ['href'] = Url::to ($url); if (strstr ($options [' href'],'?)) {$newurl = substr ($options ['href'], 0if strrpos ($options [' href'],'?')) } else {$newurl = $options ['href'];} if (!\ Yii::$app- > user- > can ($newurl)) {return false;}} return static::tag (' text, $options) } at this point, the study on "yii2 does not show the corresponding button method when there is no permission" is over. I hope to be able to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it!
