Anybody, please? Some directions?

>> Hi,
>>
>> I am trying to get into writing my own ViewHelpers. The first "bigger"
>> test is a TelephonNumber ViewHelper that transforms phone numbers to
>> links with the href:"tel:*" attr (knowing that modern devices do this
>> automatically, also knowing about the respective meta-tag... as said:
>> this is just for practicing).
>>
>> So far I got this, which works fine (thanks to the vhc collection; the
>> whole thing gets implemented into the cbgooglemaps ext):
>>
>> // Script
>> class Tx_Cbgooglemaps_ViewHelpers_Link_TelephoneNumberViewHelper extends
>> Tx_Fluid_Core_ViewHelper_AbstractTagBasedViewHelper  {
>>    protected $tagName = 'a';
>>    /**
>>     * @param string $number The phone number to parse
>>     * @param string $type The link type ("tel", "skype", "callme",...)
>>     * @return string Rendered phone link
>>     */
>>    public function render( $number, $type='tel' ) {
>>      $linkText = $number;
>>      $tagContent = $this->renderChildren();
>>      if ($tagContent !== NULL) { $linkText = $tagContent; }
>>      $this->tag->setContent($linkText);
>>      $this->tag->addAttribute('href', $type.':' .  $number);
>>      return $this->tag->render();
>>    }
>> }
>>
>> // Template
>> {namespace l=Tx_Cbgooglemaps_ViewHelpers}
>> Telefon: <l:Link.TelephoneNumber
>> number="{phone}">{phone}</l:Link.TelephoneNumber>
>>
>>
>> So far, so good. The problem starts, when there are is a list of comma
>> seperated phone numbers to deal with. I started out with this:
>>
>> public function render( $number, $type='tel' ) {
>>    $explodeStr = ",";
>>    // if $number is an array...
>>    if( strpos( $number, explodeStr) ){
>>      $numberArray = trim( explode( explodeStr, $number ));
>>        foreach ( $numberArray as $num ) {
>>          // how to deal with the $this->tag->foo, when
>>          // there is only one tag?
>>          // how shall the return value be put together?
>>        }
>>    } else {
>>      // code as before
>>    }
>> [...]
>>
>>
>> As the comments already say, I do not know how to deal with the
>> render->children() and the like commands. Also, the final render-command
>> has to be placed outside the foreach loop, right? So what would be the
>> proper way to build it?
>>

>> Thanks for your hints!
