In case you want to support admin can control the prices of your app (price for feature item, sponsor item, etc...), this document can help you how to add a setting/user group setting for price with multiple currencies

In this doc, we will use the app To Do List for example.

h2. in Settings

First, we will configure price for featuring a to do list:

Open file Install.php, modify function setSettings with the following code

Code Block

	php
	php


$this->settings = [
    'td_can_user_privacy' => [
        'var_name'      => 'td_can_user_privacy',
        'info'          => 'Allow user add privacy',
        'description'   => 'Enable this setting in case you want your user can use privacy during adding new todo list',
        'type'          => \Core\App\Install\Setting\Site::TYPE_RADIO,
        'value'         => '1',
    ],
    'td_feature_price' => [
        'var_name'    => 'td_feature_price',
        'info'        => 'How much does it cost to feature a todo list?',
        'type'        => \Core\App\Install\Setting\Site::TYPE_CURRENCY,
        'value'       => serialize(['USD' => 2])
    ]
];

...

When you want to get the values of the price, you can use below code:

Code Block

	php
	php


$aFeaturePrice = unserialize(setting('td_feature_price'));
/**
*   $aFeaturePrice will have array type, below is an example
*   ['USD' => 2]
*/

in User Group Settings

Phpfox also support price with multiple currencies in User Group Settings.
For example: we will configure sponsor price for each user groups.

Open file Install.php, modify function setUserGroupSettings with the following code

Code Block

	php
	php


$this->user_group_settings = [
    'td_can_add_new_todo_list'          => [
        'var_name' => 'td_can_add_new_todo_list',
        'info'     => 'Can add new todo list?',
        'type'     => \Core\App\Install\Setting\Groups::TYPE_RADIO,
        'value'    => [
            "1" => "1",
            "2" => "1",
            "3" => "1",
            "4" => "1",
            "5" => "0"
        ],
        'options'  => \Core\App\Install\Setting\Groups::$OPTION_YES_NO
    ],
    'td_user_sponsor_price' => [
        'var_name' => 'td_user_sponsor_price',
        'info' => 'How much does it cost to sponsor a todo list?',
        'type' => \Core\App\Install\Setting\Groups::TYPE_CURRENCY,
        'value' => [
            "1" => serialize(['USD' => 2]),
            "2" => serialize(['USD' => 4]),
            "3" => serialize(['USD' => 7]),
            "4" => serialize(['USD' => 9]),
            "5" => ''
        ],
    ]
];

...

To get the price value, we can use:

Code Block

	php
	php


$aUserSponsorPrice = unserialize(user('td_user_sponsor_price'));
/**
*   $aUserSponsorPrice will have array type, below is an example
*   ['USD' => 2]
*/
