How to pass user identify in a field?

Yii 2.0 General Discussions
1

Hello,

I am trying to pass the logged in user identity in a _form field but cannot work out how to do it, could you please help me?




//This is what I tried but get errors


<?= $form->field($model, $user = \Yii::$app->user->identity); ?>

Thanks,

Ben

If user identity has a username field, that will be:




//This is what I tried but get errors


<?= $form->field($model, $user = \Yii::$app->user->identity->username); ?>

otherwise you are passing entire object.

Sorry Fabrizio I did not understand what you mean.

With the above code I get this:




PHP User Error – yii\base\ErrorException


Exception 'yii\base\InvalidParamException' with message 'Attribute name must contain word characters only.'

What Fabrizio wanted to tell you is that the user identity holds attributes of the currently logged in user…

Try for example:




echo \Yii::$app->user->identity->username; // gives out the username

echo \Yii::$app->user->identity->id; // gives the ID

Regarding your question it should be something like:


echo $form->field($model, 'yourFieldName')->textInput(['value' => \Yii::$app->user->identity->id;]);

"yourFieldName" must be the name of the attribute you want to fill.

For example "user_id" or whatever you called it in your DB.

Sorry, I thought that I was writing in textInput method …

MetaCrawler answered to you.

Thanks to both of you.

Got it working, I have an error about object not set but this was because I was not logged in :-))

Thanks again!
