Protect

aMember Pro provides almost zero-programming integration API to interface with third-party scripts.

Note: try to use http://example.com/amember/admin-plugin-maker. It is a great tool that will make an integration plugin template for you.

Without single-login, you have to define only 3 variables and 3 functions:

• $guessTablePattern and $guessTableFields - 3rd party script users table name without prefix, and some fields from it
• $groupMode - can be GROUP_NONE for no user groups (user can be just enabled/disabled), GROUP_SINGLE if customer is assigned to 1 usergroup only, and GROUP_MULTI if user can be assigned to multiple user groups in the same time
• createTable() : set relations between customer table fields in 3rd party script, and aMember fields
• getPasswordFormat() : a constant from SavedPass class or an unique string for new password format
• getAvailableUserGroups() : return groups list from 3rd party script (required if $groupMode is not GROUP_NONE)

There is a simple example based on SMF plugin:

// file am/application/default/plugins/protect/smf.php
class Am_Protect_Smf extends Am_Protect_Databased
{
    const PLUGIN_STATUS = self::STATUS_DEV;
    const PLUGIN_REVISION = '@@VERSION@@';

    const SMF = 'smf';

    protected $guessTablePattern = "members";
    protected $guessFieldsPattern = array(
        'ID_MEMBER', 'memberName',
    );
    protected $groupMode = self::GROUP_SINGLE;

    public function afterAddConfigItems(Am_Form_Setup_ProtectDatabased $form)
    {
        parent::afterAddConfigItems($form);
        // @todo eliminate necessarity of prefix here!
        $form->addText('protect.smf.cookie')->setLabel('SMF Cookie Name');
    }
    public function getPasswordFormat()
    {
        return self::SMF;
    }

    public function cryptPassword($pass, &$salt = null, User $user = null)
    {
        $salt = substr(md5(mt_rand()), 0, 4);
        return sha1(strtolower($user->login) . $this->un_htmlspecialchars(stripslashes($pass)));
    }

    /// what the shit is it for in password hashing? who knows...
    function un_htmlspecialchars($string)
    {
        return strtr($string, array_flip(get_html_translation_table(HTML_SPECIALCHARS, ENT_QUOTES)) + array(''' => '\'', ' ' => ' '));
    }

    public function getLoggedInRecord()
    {
        if (!$this->getConfig('cookie')) return;
        $cookie = @$_COOKIE [ $this->getConfig('cookie') ];
        if (!$cookie) return;
        $vars = unserialize($cookie);
        if (!$vars[0]) return;
        $user_id = (int)$vars[0];
        $pwd       = $vars[1];
        if (!$user_id || !$pwd) return;
        $record = $this->getTable()->load($user_id, false);
        if (!$record->isLoaded()) return;
        if ($pwd != sha1($record->passwd . $record->passwordSalt)) return;
        return $record;
    }

        $data = array(

            sha1($record->passwd . $record->passwordSalt),
            time() + 3600, // expires
            0, // cookie state
        );
        Am_Controller::setCookie($this->getConfig('cookie'), serialize($data));

        // update user record
        $ip   = $_SERVER['REMOTE_ADDR'];
        $ip2 = $_SERVER['REMOTE_ADDR'];
