Linkable Behavior for Yii2 Components

This extension help creating urls easier in yii2. This behavior provides support for components that have a page to display its contents. The page can be an action in a Module or simply in a Controller. It will be easier to get links related to this record without having to write Url Route over and over again.

Installation

The preferred way to install the library is through composer.

Either run

php composer.phar require --prefer-dist locustv2/yii2-linkable-behavior

or add

{
    "require": {
        "locustv2/yii2-linkable-behavior": "~1.0.0"
    }
}

to your composer.json file.

Usage

Add the behavior to your ActiveRecord that can he hotlinked:

namespace app\models;

use yii\db\ActiveRecord;
use locustv2\behaviors\LinkableBehavior;

class User extends ActiveRecord
{
  //...

    public function behaviors()
    {
        return ArrayHelper::merge(parent::behaviors(), [
            [
                'class' => LinkableBehavior::className(),
                'route' => '/user',
                'defaultAction' => 'view',
                'hotlinkTextAttr' => 'username',
                'defaultParams' => function ($record) {
                    return [
                        'id' => $record->id,
                    ];
                },
            ]
        ]);
    }
}

namespace app\models;

use yii\db\ActiveRecord;
use locustv2\behaviors\LinkableBehavior;

class Photo extends ActiveRecord
{
  //...

    public function behaviors()
    {
        return ArrayHelper::merge(parent::behaviors(), [
            [
                'class' => LinkableBehavior::className(),
                'route' => '/photo',
                'defaultAction' => 'view',
                'linkableParams' => function ($record) {
                    return [
                        'photoid' => $record->id,
                    ];
                },
                'useAbsoluteUrl' => true,
                'defaultParams' => function ($record) {
                    return [
                        'id' => $record->id,
                        'slug' => $record->slug
                    ];
                },
            ]
        ]);
    }
}

With that code in place, you can now use 4 available methods in your User and Photo ActiveRecord:

• getUrlRoute($action = null, array $params = [])
• getUrlRouteTo(Component $component, $action = null)
• getHotlink($action = null, array $params = [], array $options = [])
• getHotlinkTo(Component $component, $action = null, array $params = [], array $options = [])

Examples (assuming that you use pretty urls)

getUrlRoute($action = null, array $params = [])

use yii\helpers\Url;
use app\models\User;

$user = User::findOne(['id' => 123]);

// /user/view?id=123
echo Url::to($user->urlRoute);

// /user/update?id=123
echo Url::to($user->getUrlRoute('update'));

// http://www.yoursite.com/user/profile?id=123&ref=facebook
echo Url::to($user->getUrlRoute('profile', ['ref' => 'facebook']), true);

getUrlRouteTo(Component $component, $action = null)

use yii\helpers\Url;
use app\models\User;

$user = User::findOne(['id' => 123]);
$photo = $user->getPhotos()->one();

// /user/photo/view?id=123&photoid=456&slug=my-first-photo
echo Url::to($user->getUrlRouteTo($photo));

// /photo/user/view?id=456&slug=my-first-photo&uid=123
echo Url::to($photo->getUrlRouteTo($user));

// /user/photo/update?id=123&photoid=456&slug=my-first-photo
echo Url::to($user->getUrlRouteTo($photo, 'update'));

getHotlink($action = null, array $params = [], array $options = [])

use yii\helpers\Url;
use app\models\User;

$user = User::findOne(['id' => 123]);

// <a href="/user/view?id=123">Locustv2</a>
echo $user->hotLink;

// <a href="/user/update?id=123">Locustv2</a>
echo $user->getHotlink('update');

// <a class="text-bold" href="/user/profile?id=123&ref=facebook">Locustv2</a>
echo $user->getHotlink('profile', ['ref' => 'facebook'], ['class' => 'text-bold']);

If you want to use absolute urls, you should set LinkableBehavior::$useAbsoluteUrl to true. If you want to disable hotlinks, you should set LinkableBehavior::$disableHotlink to true. <span/> will be used instead of <a/>

getHotlinkTo(Component $component, $action = null, array $params = [], array $options = [])

use yii\helpers\Url;
use app\models\User;

$user = User::findOne(['id' => 123]);
$photo = $user->getPhotos()->one();

// <a href="http://www.yoursite.com/user/photo/view?id=123&photoid=456&slug=my-first-photo">Locustv2</a>
echo $user->getHotlinkTo($photo);

// <a href="http://www.yoursite.com/photo/user/view?id=456&slug=my-first-photo&uid=123">http://www.yoursite.com/photo/user/view?id=456&slug=my-first-photo&uid=123</a>
echo $photo->getHotlinkTo($user);

// <a class="font-bold" href="http://www.yoursite.com/user/photo/update?id=123&photoid=456&slug=my-first-photo&ref=homepage">Locustv2</a>
echo Url::to($user->getHotlinkTo($photo, 'update', ['ref' => homepage], ['class' => 'font-bold']));
