Multiple Variables to be passed in URL - Yii2

Question

I want to generate URL's that can handle multiple parameters as follows.

www.mysite.com/index.php/controller/param1/param2/param3/param4/mySlug

But still be able to be flexible and pass over less information

www.mysite.com/index.php/controller/param1/parama/my_slug_2

We could assume there's always a slug at the end if that makes this easier. Is there anything in the Yii2 urlManager I can implement this.

Just configure your rule with default values of your params like this:

'urlManager' => [
        'enablePrettyUrl' => true,
        'showScriptName' => false,
        'rules' => [
            [
                'pattern' => 'test/<param1:\d+>/<param2:\d+>/<param3:\d+>/<param4:\d+>/<slug>',
                'route' => 'site/test',
                'defaults' => [
                    'param1' => null,
                    'param2' => null,
                    'param3' => null,
                    'param4' => null,
                ]
            ]
        ]
    ],

All the parameters, that have default value are not required and may be skipped. Here are the examples of behaviour:

http://yii2.local/test/slug:

skipped.array (size=5)
  'param1' => null
  'param2' => null
  'param3' => null
  'param4' => null
  'slug' => string 'slug' (length=4)

http://yii2.local/test/2/4/slug

array (size=5)
  'param1' => string '2' (length=1)
  'param2' => string '4' (length=1)
  'param3' => null
  'param4' => null
  'slug' => string 'slug' (length=4)

This looks Good, will come back once implemented to let you know if it worked. – ahervin Nov 09 '15 at 15:10
@ahervin Was it successful to you? – SilverFire Nov 16 '15 at 14:54
I've made note on the task to update this answer when I implement. Apologies for the Delay. – ahervin Nov 16 '15 at 15:41
I'll mark this as correct as it's working sometimes but I need to sort some conflicting rules. – ahervin Nov 20 '15 at 16:00
You always can create your own class that extends `UrlRule` and implement you own logic of handling of multiple optional parameters with the proper order. – SilverFire Nov 21 '15 at 17:57

This works a bit nicer, as it allows for any number of optional params, great if for example you're creating a category tree that may be x levels deep (you also don't need slug if not needed):

In the config:

'urlManager' => [
    'enablePrettyUrl' => true,
    'showScriptName' => false,
    'rules' => [
        [
            'pattern' => 'test/<params:.*>/<slug>',
            'route' => 'site/test',
            'encodeParams' => false,
            'defaults' => [
                'params' => null,
            ]
        ]
    ]
],

You can then get an array of all possible params in the controller:

public function actionTest($params = null, $slug) {     
    
    $params = !empty($params) ? explode('/', $params) : null;
    
    // do whatever...

}

Horrible that this is a 2 year question, and the answer is so simple.

The idea is that for some reason when the ActiveForm is not well configure for the GET requests, specifically on the action, it will cause this weird effect.

Explanation: The reason for the above behavior is due to a unique validation needed in Yii's Html::beginForm method. The query parameters in the action are ignored for GET method so Yii's Html::beginForm uses hidden inputs for each GET parameter to add them back. These hidden inputs gets stacked over the last URI call with every submission. «Yii Forum»

This can get solved by simply adding a well configured action to the $form = ActiveForm.

On Yii2:

$form = ActiveForm::begin([
                'method' => 'get',
                'action' => Url::to(['/search']),
            ]);

This will get rid of this horrible effect. For more info on this read the Yii forum

I hope this helps any other, that runs on the problem.
