Yii can't start gii

Question

I am developing website with PHP Yii Framework and I am now stack, I need to start gii, but I can't do this. when i type www.example.com/index.php/gii or www.example.com/gii it gives me this error :

    /gii/default/login // <- website redirects to here

    This webpage has a redirect loop
    The webpage at http://www.example.com/gii/default/login has resulted in too many redirects.
Clearing your cookies for this site or allowing third-party cookies may fix the problem. 
If not, it is possibly a server configuration issue and not a problem with your computer.

I don't think that the error is because of modified htaccess and main configuration, but anyway here is main.php configuration file:

    'urlManager'=>array(
        'urlFormat'=>'path',
        'showScriptName'=>false,
        'rules'=>array(
            'site/page/<view:\w+>'=>'site/page',
            '<controller:\w+>/<cact:\w+>/<action:\w+>'=>'<controller>/<cact>',
            '<controller:\w+>/<id:\d+>'=>'<controller>/view',
            '<controller:\w+>/<action:\w+>/<id:\d+>'=>'<controller>/<action>',
            '<controller:\w+>/<action:\w+>'=>'<controller>/<action>',
        ),
    ),

and .htaccess :

Options +FollowSymLinks
IndexIgnore */*
RewriteEngine on

#non-www to www
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

# if a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

# otherwise forward it to index.php
RewriteRule ^.*$ /index.php [L]

So can you help me, please?

Answer 1

要使用此路径： index.php?r=gii/default/login ，您必须关闭/protected/config/main.php的url管理器

Answer 2

Also check urlManager 's rules . That was the issue for me:

'components' => array(
    'urlManager' => array(
        'urlFormat' => 'path',
        'showScriptName' => false,
        'rules' => array(
            // ...
            // will handle `gii/default/login` uri and makes infinite redirection loop circle
            '<controller:\w+>/<action:\w+>/<sub_action:\w+>'=>'<controller>/<action>',
            // ...
        ),
     ),
 ),

Like FelikZ mentioned , this might be because you have created a third param in a rule that uses \\w+ instead of the default \\d+ and hence will match "gii" as the controller, "default" as the action and "login" as the ID (or sub action, or whatever is mentioned).

My rules looked like the following:

'<controller:\w+>/<action:\w+>/<id:\w+>'=>'<controller>/<action>',
'<controller:\w+>/<action:\w+>'=>'<controller>/<action>',

The fix is to add the following as the very first rule in order to make gii hit the right place:

'gii/<controller:\w+>/<action:[\w-]+>' => 'gii/<controller>/<action>',

Which should make your entire urlManager config look something like the following:

'urlManager'=>array(
    'urlFormat'=>'path',
    'showScriptName'=>false,
    'rules'=>array(
        'gii/<controller:\w+>/<action:[\w-]+>' => 'gii/<controller>/<action>',

        '<controller:\w+>/<action:\w+>/<id:\w+>'=>'<controller>/<action>',
        '<controller:\w+>/<action:\w+>'=>'<controller>/<action>',
    ),
),

Answer 4

Check if the gii module in your configuration file is there and it is uncommented. If gii is not in there you should add it within the module array.

'modules'=>array(
    'gii'=>array(
        'class'=>'system.gii.GiiModule',
        'password'=>***choose a password***
    ),
),
