Global Bootstrap Version

Generally, you may also want to set a default version globally for all Krajee Extensions (instead of setting it for each widget or extension separately). In order to do this, you can setup the bsVersion property within Yii 2 application params (i.e. Yii::$app->params['bsVersion']). To set this up, add this section of code to your application params configuration file (e.g. config/params.php):

'params' => [
    'bsVersion' => '5.x', // this will set globally `bsVersion` to Bootstrap 5.x for all Krajee Extensions
    // other settings
    // 'adminEmail' => 'admin@example.com'
]

If IpInfo::bsVersion property is set, in addition to Yii::$app->params['bsVersion'], the extension level setting (IpInfo::bsVersion property) will override the Yii::$app->params['bsVersion']. If IpInfo::bsVersion property is not set, and Yii::$app->params['bsVersion'] is also not set, IpInfo::bsVersion property will default to 3.x (i.e. Bootstrap 3.x version will be assumed as default).

Yii2 Bootstrap Dependency

You need to install one of yiisoft/yii2-bootstrap or yiisoft/yii2-bootstrap4 or yiisoft/yii2-bootstrap5 extensions manually in your application to enable Bootstrap 3.x or 4.x or 5.x functionality respectively. This dependency has not been pre-built into the composer configuration for Krajee extensions, to allow better control to the developers in configuring their bootstrap library version. If bsVersion is set to 5.x and yiisoft/yii2-bootstrap5 is not installed, then an exception message will be thrown mentioning you to install the yiisoft/yii2-bootstrap5 extension. If bsVersion is set to 4.x and yiisoft/yii2-bootstrap4 is not installed, then an exception message will be thrown mentioning you to install the yiisoft/yii2-bootstrap4 extension. Similarly, if bsVersion is set to 3.x and yiisoft/yii2-bootstrap is not installed, an exception message will be thrown mentioning you to install the yiisoft/yii2-bootstrap extension.

To install yiisoft/yii2-bootstrap5, add the repo to the require section of your application's composer.json.

"yiisoft/yii2-bootstrap5": "@dev"

To install yiisoft/yii2-bootstrap4, add the repo to the require section of your application's composer.json.

"yiisoft/yii2-bootstrap4": "@dev"

To install yiisoft/yii2-bootstrap, add the repo to the require section of your application's composer.json.

"yiisoft/yii2-bootstrap": "@dev"

Override Bootstrap CSS/JS

The Krajee extension asset bundle(s) by default depend on one of the following asset bundles to load the Bootstrap CSS and JS:

• yii\bootstrap\BootstrapAsset and/or yii\bootstrap\BootstrapPluginAsset for bootstrap 3.x (bsVersion = 3 setting)

• yii\bootstrap4\BootstrapAsset and/or yii\bootstrap4\BootstrapPluginAsset for bootstrap 4.x ( bsVersion = 4 setting)

• yii\bootstrap5\BootstrapAsset and/or yii\bootstrap5\BootstrapPluginAsset for bootstrap 5.x (bsVersion = 5 setting)

This is controlled by the property bsDependencyEnabled within the asset bundle (which defaults to true). One can override this and prevent the default yii2 bootstrap assets (CSS & JS) from loading by doing one or all of the following:

• Global Override: Set Yii::$app->params['bsDependencyEnabled'] to false in your Yii 2 application config params.php. This setting will be applied for all Krajee Extension Asset Bundles that depend on Bootstrap assets.

  'params' => [
      'bsDependencyEnabled' => false, // this will not load Bootstrap CSS and JS for all Krajee extensions
      // you need to ensure you load the Bootstrap CSS/JS manually in your view layout before Krajee CSS/JS assets
      //
      // other params settings below
      // 'bsVersion' => '5.x',
      // 'adminEmail' => 'admin@example.com'
  ]
  

• Asset Bundle Specific Override: Set bsDependencyEnabled to false for the specific asset bundle within Yii2 Asset Manager component in your Yii 2 application config file.

  // ...
  'components' => [
      'assetManager' => [
          'bundles' => [
              'kartik\form\ActiveFormAsset' => [
                  'bsDependencyEnabled' => false // do not load bootstrap assets for a specific asset bundle
              ],
          ],
      ],
  ],
  

Icons for Bootstrap

Bootstrap 5.x / 4.x does not include glyphicons or any other icons framework bundled with the library. Krajee extensions therefore will use Font Awesome 5.x icons instead of glyphicons when working with Bootstrap 5.x / 4.x. You can download Font Awesome 5.x icons from the icons website. Alternatively, you can load the free version of Font Awesome from their CDN.

For Krajee extensions and demos, the Font Awesome Free version is used and loaded as the Icons Display Package on all the Yii2 demo layouts. To include font awesome assets on your page, include the following markup on the HEAD section of your view layout file, when bsVersion is set to 4.x or 5.x.

• Option 1: Font CSS version of Font Awesome:

  <!-- on your view layout file HEAD section -->
  <link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.3.1/css/all.css">
  

• Option 2: SVG / JS version of Font Awesome (recommended for cleaner scaling vector icons and features like icon layers):

  <!-- on your view layout file HEAD section -->
  <script defer src="https://use.fontawesome.com/releases/v5.3.1/js/all.js" crossorigin="anonymous"></script>
  

  Alternatively, you can use the FontAwesomeAsset from the kartik-v/yii2-icons package to load the SVG/JS version.

  // on your view layout file
  use kartik\icons\FontAwesomeAsset;
  FontAwesomeAsset::register($this);
  

Composer Package Manager Recommended

Installation via Composer is the recommended and most easy option to install Krajee Yii2 extensions. You can install yii2-ipinfo via composer package manager. Either run:

$ php composer.phar require kartik-v/yii2-ipinfo "dev-master"

or add:

"kartik-v/yii2-ipinfo": "dev-master"

to your application's composer.json file.

Manual Install

You may also manually install the extension to your project (in case your composer install does not work). Just download the source ZIP or TAR ball and extract the extension asset files and folders into your project. You may need to install dependencies manually and also set the namespaces to the extensions in your Yii2 extensions configurations manually.

bsVersion

• To use with Bootstrap library - you can set this to any string starting with 3 (e.g. 3 or 3.3.7 or 4.x / 3.x)

• To use with bootstrap 4 - you can set this to any string starting with 4 (e.g. 4 or 4.6.0 or 4.x)

• To use with bootstrap 5 - you can set this to any string starting with 4 (e.g. 5 or 5.1.0 or 5.x)

bsColCssPrefixes

array, the bootstrap grid column css prefixes mapping, the key is the bootstrap versions, and the value is an array containing the sizes and their corresponding grid column css prefixes. The class using this trait, must implement kartik\base\BootstrapInterface. If not set will default to:.

[

      self::SIZE_X_SMALL => 'col-xs-',
      self::SIZE_SMALL => 'col-sm-',
      self::SIZE_MEDIUM => 'col-md-',
      self::SIZE_LARGE => 'col-lg-',
      self::SIZE_X_LARGE => 'col-lg-',
      self::SIZE_XX_LARGE => 'col-lg-',
   ],
   4 => [
      self::SIZE_X_SMALL => 'col-',
      self::SIZE_SMALL => 'col-sm-',
      self::SIZE_MEDIUM => 'col-md-',
      self::SIZE_LARGE => 'col-lg-',
      self::SIZE_X_LARGE => 'col-xl-',
      self::SIZE_XX_LARGE => 'col-xl-',
   ],
   5 => [
      self::SIZE_X_SMALL => 'col-',
      self::SIZE_SMALL => 'col-sm-',
      self::SIZE_MEDIUM => 'col-md-',
      self::SIZE_LARGE => 'col-lg-',
      self::SIZE_X_LARGE => 'col-xl-',
      self::SIZE_XX_LARGE => 'col-xxl-',
   ],
];

api

string, the api used for fetching the IP information in json format. Defaults to https://ip-api.com/json/{ip}. Note that this default API service from ip-api is free only for non commercial use. The token {ip} in the API url will be replaced with the source ip address set in ip. You can override this to any other IP API service of your choice. You may need to change the fields, modelClass and detailViewConfig to match your choice.

ip

string, the ip address. If this is not set, the current request user's ip address will be used.

modelClass

string, the model class used for rendering the ip information. Defaults to \kartik\ipinfo\IpInfoModel. To use your own API service or to customize the model, you can extend \kartik\ipinfo\IpInfoModel and set it to your own modelClass.

detailViewClass

string, the Yii2 Detail View widget class used for rendering the ip details information in a tabular form. Defaults to \yii\widgets\DetailView.

detailViewConfig

array, the configuration of the Detail View widget class used for rendering the ip details information in a tabular form. Defaults to \yii\widgets\DetailView.

detailRowOptions

array, the HTML attributes for each detail view table row.

params

array, any additional query or request parameters to pass to the IP API set via api.

requestConfig

array, the default Yii2 HTTP Client request configuration.

cache

boolean, whether to cache ip information in the server cache for the session. If set to true, the Yii2 application cache component will be used for caching. If Yii2 caching component is not set or disabled, the caching will be ignored silently without any exceptions. Using caching, will optimize and reduce server api calls for ip addresses already parsed in the past.

If this is set to true, ensure you have configured the cache component in your Yii2 configuration file similar to the example shown below:

'components' => [
    'cache' => [
        'class' => 'yii\caching\FileCache', // or any other caching component you desire with other settings
    ]
]

template

array, the template configuration for rendering the popover button, popover content, or inline content. This should be set as $key => $value pairs, where $key is one of:

• popoverButton: this is the template for popover button label (applied when showPopover is true)

• popoverContent: this is the template for popover content displayed on click of the button (applied when showPopover is true).

• inlineContent: this is the template for inline content when showPopover is set to false.

The $value is the template setting and can contain tags in braces, which will represent value of each IP position field (set in fields property) fetched from the https://ip-api.com/ API (for example {country_code}, {country_name} etc.). The following additional special tags will be replaced:

• {flag}: Will be replaced with the flag icon rendered based on the showFlag setting.

• {table}: Will render all fields configured via fields in a tabular format of labels and values.

showFlag

boolean, whether to display the country flag in one of the main template sections (defined in template) by parsing the ip address. Defaults to true.

showPopover

boolean, whether to show position details in a popover on click of the flag. If set to false, the results will be rendered inline. Defaults to true. This will use the yii2-popover-x extension by Krajee for rendering the popover.

hideEmpty

boolean, whether to hide / skip display of fields in the Detail View which have empty values (null or empty). Defaults to true.

errorData

array, the markup to be displayed when any exception is faced during processing by the API (e.g. no connectivity). You can set this to a blank string to not display anything. The following tokens will be replaced:

• {errorIcon}: with the icon markup set in errorIcon.

• {message}: any error message returned by api.

errorDataOptions

array, the HTML attributes for error data container. Defaults to: ['title' => 'IP fetch error']. The following special tags are recognized:

• tag: string, the HTML tag in which the content will be rendered. Defaults to div.

    'reverse',
    'mobile',
    'proxy',
]

fields

array, the list of names of fields/ attributes which will be skipped from tabular display. Defaults to empty array (which means no fields will be skipped from display). Note that this setting will override the fields setting.
