TYPO3 7.6.10：如何扩展felogin扩展？

Question

I tried to extend the core extension felogin with an extra extension called "feloginextended".

I want to add the first_name and the last_name property of the current user into my logout formular.

This is my overridden template (only the logout part):

<!--###TEMPLATE_LOGOUT###-->
<form class="login-form" action="###ACTION_URI###" target="_top" method="post">
    <div>
        <div class="user">###FIRSTNAME### ###LASTNAME###</div>
        <a class="page-link-button" href="http://tf.lightblue.eu/index.php?id=14">Meine Siegel</a>
        <a class="page-link-button" href="http://tf.lightblue.eu/index.php?id=15">Mein Account</a>
        <input class="form-btn" type="submit" name="submit" value="Logout" />
     </div>

    <div class="felogin-hidden">
        <input type="hidden" name="logintype" value="logout" />
        <input type="hidden" name="pid" value="###STORAGE_PID###" />
        <input type="hidden" name="###PREFIXID###[noredirect]" value="###NOREDIRECT###" />
    </div>
</form>
<!--###TEMPLATE_LOGOUT###-->

Then I added the Controller Classes\Xclass\FrontendLoginController to my extension.

I copied the original file and add some changes in the showLogout function, to set the markers:

 <?php
 namespace Typo3\feloginextended\Xclass;

 use \TYPO3\CMS\Frontend\Plugin\AbstractPlugin;

 /**
  * Plugin 'Website User Login' for the 'felogin' extension.
  */
 class FrontendLoginController extends AbstractPlugin
 {

 /**
 * Shows logout form
 *
 * @return string The content.
 */
protected function showLogout()
{
    $subpart = $this->cObj->getSubpart($this->template, '###TEMPLATE_LOGOUT###');
    $subpartArray = ($linkpartArray = array());
    $markerArray['###STATUS_HEADER###'] = $this->getDisplayText('status_header', $this->conf['logoutHeader_stdWrap.']);
    $markerArray['###STATUS_MESSAGE###'] = $this->getDisplayText('status_message', $this->conf['logoutMessage_stdWrap.']);
    $this->cObj->stdWrap($this->flexFormValue('message', 's_status'), $this->conf['logoutMessage_stdWrap.']);
    $markerArray['###LEGEND###'] = $this->pi_getLL('logout', '', true);
    $markerArray['###ACTION_URI###'] = $this->getPageLink('', array(), true);
    $markerArray['###LOGOUT_LABEL###'] = $this->pi_getLL('logout', '', true);
    $markerArray['###NAME###'] = htmlspecialchars($this->frontendController->fe_user->user['name']);
    $markerArray['###STORAGE_PID###'] = $this->spid;
    $markerArray['###USERNAME###'] = htmlspecialchars($this->frontendController->fe_user->user['username']);
    $markerArray['###USERNAME_LABEL###'] = $this->pi_getLL('username', '', true);
    $markerArray['###NOREDIRECT###'] = $this->noRedirect ? '1' : '0';
    $markerArray['###PREFIXID###'] = $this->prefixId;
    // my custom changes-----------------------------------
    $markerArray['###FIRSTNAME###'] = htmlspecialchars($this->frontendController->fe_user->user['first_name']);
    $markerArray['###LASTNAME###'] = htmlspecialchars($this->frontendController->fe_user->user['last_name']);
    //------------------------------------------------------
    $markerArray = array_merge($markerArray, $this->getUserFieldMarkers());
    if ($this->redirectUrl) {
        // Use redirectUrl for action tag because of possible access restricted pages
        $markerArray['###ACTION_URI###'] = htmlspecialchars($this->redirectUrl);
        $this->redirectUrl = '';
    }
    return $this->cObj->substituteMarkerArrayCached($subpart, $markerArray, $subpartArray, $linkpartArray);
}
}

Then I register my template in the ext_typoscript_setup.txt file:

plugin.tx_felogin_pi1 {
    templateFile = EXT:feloginextended/Resources/Private/Templates/FrontendLogin.html
}

And my final step was the registration of the controller in the ext_localconf.php:

<?php
if (!defined('TYPO3_MODE')) {
    die('Access denied.');
}

$GLOBALS['TYPO3_CONF_VARS']['SYS']['Objects']['TYPO3\\CMS\\Felogin\\Controller\\FrontendLoginController'] = array(
    'className' => 'Typo3\\Feloginextended\\Xclass\\FrontendLoginController',
);
$GLOBALS['TYPO3_CONF_VARS']['SYS']['Objects']['tx_felogin_pi1'] = $GLOBALS['TYPO3_CONF_VARS']['SYS']['Objects']['TYPO3\\CMS\\Felogin\\Controller\\FrontendLoginController'];

If add this changes into the original files of the felogin extension, then I have a solution.

But this way is very dirty and in the future I can't update the felogin extension easily.

I found this "solution": https://forum.typo3.org/index.php/t/202500/ But it don't work for me.

Have anyone an idea or have an other way to bring the first and the last name of the current user to the logout formular?

EDIT: I get everytime a http error 500!

Thanks Felix

The solution is pretty simple. You can just add the markers ###FEUSER_FIRST_NAME### and ###FEUSER_LAST_NAME### to your template and they will be replaced by the right values. This schema is general and can be used on all fields of the user:

###FEUSER_{DB field in uppercase}###. Note that the fields are used with underscores and not the lower camelcase.

This works in TYPO3 6.x and the code looks the same in 7.6 so it should work too.
