[TYPO3-mvc] viewhelper for first char register

[Johannes C. Schulz - EnzephaloN IT-Solutions]

Hey Claus

Thanx a lot! It looks good, but I have to play around until it will work, I think...
My object is "hotel", so the call is {hotel.initialLetter}, or?
I place the php file in the ViewHelpers folder or in ViewHelpers/Widget?
And I have to change templateVariableContainer to MyObjectClass?

Sorry for the dumb questions...

Best regards
Johannes

Hi Johannes,
  
  Perhaps you can use this:
  
  <?php
  
  /**
   * Outputs a letter header if the passed letter is different from the last
   *
   * @package TYPO3
   * @subpackage Fluid
   * @version
   */
  class Tx_Personnel_ViewHelpers_StartLetterViewHelper extends Tx_Fluid_Core_ViewHelper_AbstractViewHelper {
   
   /**
    * Render a select
    * @param string $string
    * @return string
    */
   public function render($string) {
    $letter = strtoupper($string{0});
    if ($this->templateVariableContainer->exists('initialLetter')) {
     $existing = $this->templateVariableContainer->get('initialLetter');
     if ($letter != $existing) {
      $this->templateVariableContainer->remove('initialLetter');
      $this->templateVariableContainer->add('initialLetter', $letter);
      return '<h4>' . $letter . '</h4>';
     }
    } else {
     $this->templateVariableContainer->add('initialLetter', $letter);
     return '<h4>' . $letter . '</h4>';
    }
   }
  }
   
  
  ?>
  
  You can (if you don't need the {initialLetter} Fluid variable) change to use $this->viewHelperVariableContainer->add() … etc. Just remeber that the ViewHelperVariableContainer requires a class name as first argument, the following arguments are just the same as for TemplateVariableContainer.
  
  Cheers,
  Claus
