Hello everybody. recently I switched from CakePHP to Yii and I must say I’m more than satisfied with Yii.
I followed the book until chapter 8 page 210 and I’m stuck there. If someone can help it will be apreciated.
On page 210 we have snippet of code so we can access form for adding user to project
The following line was
added to the project show.php view fle's list of link options:
[<?php echo CHtml::link('Add User To Project',array('adduser','id'=>$m
odel->projectId)); ?>]
My question is were exactly to put link above in menu array. I folowed instruction till en of this chapter and
when I try to access page to add user to project I got the message:
PHP Error
