It seems as if I found a working way:
// Class
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') {
$explodeStr = ",";
$content = "";
if (strpos($number, $explodeStr)) {
$i = 0;
$numberArray = explode($explodeStr, $number);
foreach ($numberArray as $num) {
$i++;
$content .= "<a href='" . $type . ":" .
self::clearPhoneNumber(trim($num)) . "'>" . trim($num) . "</a>";
if ($i < count($numberArray)) {
$content .= ", ";
}
}
} else {
$content .= "<a href='" . $type . ":" .
self::clearPhoneNumber(trim($number)) . "'>" . trim($number) . "</a>";
}
return $content;
}
/**
* This method strips unwanted characters from the given telephone
number,
* such as white spaces or brackets
*
* @param string $number The number to be parsed
*
* @return string parsed
* @static
* @author Daniel Regelein <daniel.regel...@diehl-informatik.de>
*/
private static function clearPhoneNumber($number) {
$search = array('(', ')', '-', ' ', '/', '\\', '|', '{', '}',
'[', ']');
return str_replace($search, '', $number);
}
}
// Template
{namespace l=Tx_Cbgooglemaps_ViewHelpers}
Telefon: <l:Link.TelephoneNumber number="{phone}" />
I just have my doubts, whether this is a good solution. Doesn't feel
very "Fluid".
I'd apprciate any comments on how to improve this ViewHelper!
Thanks! Robert
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!
Greetings, Robert
