Hanna Code Snippets

Image from RepeaterMatrix or Repeater

<?php
// include a image from the parent page
if (!function_exists('getImagePage')) {
    
    function getImagePage($myPage, $level=1){
        // if in repeater or repeaterMatrix find the first parent ProcessWire\Page Page
        $maxLevel=5;
        if( get_class($myPage) == 'ProcessWire\RepeaterMatrixPage' || get_class($myPage) == 'ProcessWire\RepeaterPage') {
            $level +=1;
            if($level > $maxLevel) return false;
            $forPage = $myPage->getForPage();
            //var_dump( $myPage->getForPage());

Repeater Matrix Item von beliebiger Seite rendern

Attributes

pageid

    $out .= '<p class="uk-alert">To use this Hanna Code you need the parameters pageid (see admin page tree) and itemid. To tet the available item ids you can set the parameter list=1.</p>';
}
echo $out;

Content einer beliebigen Seite rendern

Hier am Beispiel einer Seite die Charts rendert (Template chart).

chart pageid=1234

<?php namespace ProcessWire;
// if in repeater or repeaterMatrix find the first parent ProcessWire\Page Page
if (!function_exists('getParentPage')) {
    function getParentPage($myPage, $level=1){
        $maxLevel=3;
        if( get_class($myPage) == 'ProcessWire\RepeaterMatrixPage' || get_class($myPage) == 'ProcessWire\RepeaterPage') {
            $level +=1;
            if($level > $maxLevel) return false;
            $forPage = $myPage->getForPage();
            //var_dump( $myPage->getParentPage());
            //echo("<p>next Level: ".get_class($forPage)."</p>");
            return $myPage = getParentPage($forPage);
        }else if( get_class($myPage) == 'ProcessWire\Page'){  
            return $myPage;
        }
    }
}

$parent = getParentPage($page);
$parent->hasChart = true;
$chart = $pages->get($pageid); // this page contains our content. You should ommit appendFile in it's template because we don't want <head> etc. 
$out ='';
$out .= $chart->render();

echo $out;

An Funktion durchreichen

Wenn du die Hanna Formatierung für andere Dinge nutzen willst kannst du den Code auch einfach wieder ausgeben und dann die Seite selbst parsen. Wann das sinnvoll ist musst du selbst entscheiden...

// Hanna code [[more]]:
<?php namespace ProcessWire;
// This tag is handled by template (readMore() Function in helpers.inc)
// so we just pass that tag through
echo('[[more]]');

// IN HELPERS
function readMore($text){
	$readMore = __('Read more');
	$readLess = __('Read less');
	if($text){
		$pos = strpos($text, '[[more]]', true);
		if($pos){
			$moreLink = '<div class="more-trigger" data-more="'.$readMore.'" data-less="'.$readLess.'">'.$readMore.'</div>';
			$before = substr($text,0,$pos);
			$after = substr($text,$pos+8);
			return $before.'<div class="more-text" style="display:none;">'.$after.'</div>'.$moreLink;
		}else return $text;
	}
	return $text;
}

RepeaterMatrixItem aus anderer Seite rendern

Hierbei gibt es ein paar Dinge zu beachten.

Im Backend wird der Hannacode Snippets in den Labels der Items angezeigt. Das kann das Backend zerhauen. Deshalb testen wir ob wir im Admin Bereich sind und geben etwas anderes aus. Außerdem möchten wir im Template auswergen ob es über Hanna aufgerufen wurde. Dann können wir z.B. Container weglassen, die eh schon über das Elternitem kommen.

<?php namespace ProcessWire;
// shows a layoutblock from another page
// can give you a list of all available blocks on a page if you provide a page id
// @param id - Page Id of a Page or of a RepeaterMatrixPage

$out = '';
//$p = $pages->get(5725);
$p = $pages->get($id);
if( gettype($p) == 'object' ){
    $class=get_class($p);
    if($class == 'ProcessWire\RepeaterMatrixPage'){
        // output
        $currentPath = $_SERVER['REQUEST_URI'];
        $isInAdminPage = (strpos($currentPath, '/processwire/') !== false);
        if(!$isInAdminPage) $out .= $p->render();
        else $out .= 'LAYOUTBLOCK VIA HANNA CODE';
    }else if($class == 'ProcessWire\Page'){
        // information
        $out .= '<p>Gewählte Seite: '.$p->title.'</p>';
        $out .= '<h4>Layout Blocks</h4>';
        $out .= '<p>Du hast die Id einer Seite übergeben. Dieser Hanna Code benötigt die ID eines Layout Blocks. Die Seite enthält folgende Layout Blöcke verwenden:</p>';
        $out .= '<ul>';
        foreach($p->layout_blocks as $i => $item){
            $out .= '<li>#'.($i+1).' [[layoutblock id='.$item->id.']] </li>';
        }
        $out .= '</ul>';
    }else{
        $out .= '<p class="uk-alert">Ungültige ID<p>';
    }
}else{
    $out .= '<p class="uk-alert">Die Id gehört zu keiner Seite.<p>';
}

echo $out;
