php - TYPO3 7.6.10: How to extend the felogin extension? -

i tried extend core extension felogin extension called "feloginextended".

i want add first_name , last_name property of current user logout formular.

this overridden template (only 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 added controller classes\xclass\frontendlogincontroller extension.

i copied original file , add changes in showlogout function, set markers:

 <?php  namespace typo3\feloginextended\xclass;   use \typo3\cms\frontend\plugin\abstractplugin;   /**   * plugin 'website user login' 'felogin' extension.   */  class frontendlogincontroller extends abstractplugin  {   /**  * shows logout form  *  * @return string 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;     // 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 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 register template in ext_typoscript_setup.txt file:

plugin.tx_felogin_pi1 {     templatefile = ext:feloginextended/resources/private/templates/frontendlogin.html } 

and final step registration of controller in 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 changes original files of felogin extension, have solution.

but way dirty , in future can't update felogin extension easily.

i found "solution": https://forum.typo3.org/index.php/t/202500/ don't work me.

have idea or have other way bring first , last name of current user logout formular?

edit: everytime http error 500!

thanks felix

the solution pretty simple. can add markers ###feuser_first_name### , ###feuser_last_name### template , replaced right values. schema general , can used on fields of user:

###feuser_{db field in uppercase}###. note fields used underscores , not lower camelcase.

this works in typo3 6.x , code looks same in 7.6 should work too.
