Inhalt einer Seite mit $page->get()[Bearbeiten]
Beispiel
<p>Visit us at:
<?php

echo $contact->address;
?>
</p>
Kürzer:
<p>Visit us at: <?=$pages->get("/about/contact/")->address?></p>
Seiten Filtern find()[Bearbeiten]
"Featured" Checkbox im Backend angehakt[Bearbeiten]
<ul>
<?php
$features = $pages->find("featured=1");
foreach($features as $feature)
echo "<li><a href='{$feature->url}'>{$feature->title}</a></li>";
?>
</ul>
Beispiel: Limitierte Ausgabe, Sortieren und in Unterverzeichnis[Bearbeiten]
$pages->find("parent=/about/press/, featured=1, limit=3, sort=-date");
oder
$pages->get("/about/press/")->children("featured=1, limit=3, sort=-date");
Finde in Kategorie
$pages->get("/about/press/")->find("featured=1, limit=3, sort=-date");
Seiten mit Template xyz[Bearbeiten]
$pages->find("template=press_release, featured=1, limit=3, sort=-date");
Ausführliches Beispiel mit Ausgabe
<ul>
<?php
$features = $pages->find("template=press_release, featured=1, limit=3, sort=-date");
foreach($features as $feature) {
echo "<li>" .

"<span class='date'>{$feature->date}</span>" .
"<p>{$feature->summary}</p>" .
"</li>";
}
?></ul>
Felder[Bearbeiten]
Label zu Feldes und Subfeldern ausgeben[Bearbeiten]
Beispiel mit dem Combo Profield. Das Prinzip funktioniert bei allen Feldern.
https://processwire.com/talk/topic/26183-getting-label-of-combo-subfield/#comment-217749
$field = $fields->get('your_combo_field_name');
$settings = $field->getComboSettings();
$subfield = $settings->getSubfield('your_subfield_name');
// get label in current user language
$label = $subfield->getLabel();
// to get in a language other than current user language
$label = $subfield->getLabel('de');
// to get localized description
$description = $subfield->getDescription();
// to get localized notes
$notes = $subfield->getNotes();
// also note you can use getLanguageValue
$label = $subfield->getLanguageValue('de', 'label');
Label eines Felds ausgeben[Bearbeiten]
Geht über das Feld-Objekt.
echo $fields->get("body")->label;
Ist ein Feld leer ?[Bearbeiten]
if($page->summary_de) { ... }
// check whitespace
if(trim($page->summary_de)) { ... }
Datumsfelder formatieren[Bearbeiten]
// aus Datumsfeldern
echo date("Y-m-d", $page->getUnformatted("closing"));
// aus Unix Timestamp mit Vanilla PHP
echo date("Y-m-d", $news->created);
setlocale(LC_TIME, "de_DE.utf8");
$weekday = strftime ( '%A' , $page->getUnformatted("date") );
$date = date("d.m.Y", $page->getUnformatted("date"));
Beispiel aus ProcessWire Blog
setlocale(LC_ALL, array('de_DE','de_DE.iso88591','de_DE.iso885915@euro','de_DE.utf8','de_DE@euro'));
$date = $page->date ? date('d.m.Y',$page->getUnformatted("date")) : date('d.m.Y',$page->getUnformatted("createdStr"));
Optionen eines Select Felds ausgeben (fieldtypeOptions)[Bearbeiten]
$options = $fieldtypes->get('FieldtypeOptions')->getOptions('YOURFIELDNAME');
foreach($options as $option) {
echo $option->id;
echo $option->value;
echo $option->title;
}
Parent von Repeater oder RepeaterMatrix finden[Bearbeiten]
Nutzt man ein Repeater Feld muss man manchmal die Seite herausfinden in der das Feld enthalten ist. Hierfür gibt es die Funktion getForPage().
if( get_class($myPage) == 'ProcessWire\RepeaterMatrixPage' || get_class($myPage) == 'ProcessWire\RepeaterPage') {
$forPage = $myPage->getForPage();
//var_dump( $myPage->getForPage());
return $myPage = getImagePage($forPage);
}
Falls man Repeater in Repeatern hat kann man auch eine rekursive Funktion nutzen:
if (!function_exists('getForPage')) {
function getForPage($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( $myPage->getForPage());
//echo("<p>next Level: ".get_class($forPage)."</p>");
return $myPage = getForPage($forPage);
}else if( get_class($myPage) == 'ProcessWire\Page'){
return $myPage;
}
}
}
Searchbar[Bearbeiten]
<!-- search form-->
<form class='search' action='<?php echo $pages->get('template=search')->url; ?>' method='get'>
<input type='text' name='q' placeholder='Search' value='<?php echo $sanitizer->entities($input->whitelist('q')); ?>' />
<button type='submit' name='submit'>Search</button>
</form>
Create Admin User[Bearbeiten]
Reset Password - Passwort zurücksetzen[Bearbeiten]
<?php
require "index.php";
$admin = $users->get('admin1'); // or whatever your username is
$admin->setAndSave('pass', 'geheim');
?>

Solution Paste the following into a file (e.g. "reset.php") in the root folder of the site, then run it.
ProcessWire version >= 2.6.9
require "index.php";
$admin = $users->get('admin'); // or whatever your username is
$admin->setAndSave('pass', 'yo123456');
ProcessWire version < 2.6.9
require "index.php";
$admin = wire('users')->get('admin');
$admin->setOutputFormatting(false);
$admin->set('pass', 'yo12345');
$admin->save('pass');
Editor Link / Login Logout Link[Bearbeiten]
_main.php
<div class="editor">
<?php
if($user->isLoggedin()) {
// if user is logged in, show a logout link
echo "<a href='{$config->urls->admin}login/logout/'>Logout ($user->name)</a>";
} else {
// if user not logged in, show a login link
echo "<a href='{$config->urls->admin}'>∆</a>";
}
// output an "Edit" link if this page happens to be editable by the current user
if($page->editable()) echo "<li class='edit nav'><a href='$page->editUrl'>Edit</a></li>";
?>
</div>

Conditions[Bearbeiten]
Bedingungen durch Oder Operator in Feldern[Bearbeiten]
Wenn das eine Feld leer ist nimm das nächste...
$t = $page->get("long_title|title");
[Bearbeiten]
// If the page has children, then render navigation to them under the body.
// See the _func.php for the renderNav example function.
if($page->hasChildren) {
$content .= renderNav($page->children);
}
// if the rootParent (section) page has more than 1 child, then render
// section navigation in the sidebar
if($page->rootParent->hasChildren > 1) {
$sidebar = renderNavTree($page->rootParent, 3) . $page->sidebar;
}
Rendering[Bearbeiten]
Es gibt viele Möglichkeiten deshalb ein eigenes Kapitel:
ProcessWire - Render Funktionen
$page Object[Bearbeiten]
Siehe auch ProcessWire - Page Object
Zugriff auf $page in Funktionen[Bearbeiten]
Beispiel:
function getTitle() {
$page = wire("page");
$t = $page->title;
oder einfach übergeben.
Variablen zu Render-Datei senden[Bearbeiten]
// you can send vars (here item count)
// use this inside the field rendering script
// ie. $page->_n
$page->set('_n',$n);
$page->set('_type',$item->type);
$out .= $item->render();
Copy and Paste[Bearbeiten]
Einfache Datumssteuerung[Bearbeiten]
Setzt Felder date_begin und date_end voraus.
// Date check
$dateValid = true;
$now = time();
$start = 0;
$end = 0;
if($page->date_begin){
$start = strtotime( $page->date_begin('Y-m-d') . " 00:00:00");
if( !($now >= $start) ) $dateValid = false;
}
if($page->date_end){
$end = strtotime( $page->date_end('Y-m-d') . " 23:59:59");
if( ($now > $end) ) $dateValid = false;
}
if(!$dateValid) return '';
Copyright / Published Date[Bearbeiten]
$published_date = date('d.m.Y',$page->created);
<?= '©'.$published_date ?>
Stylesheets und Skripte mit AIOM[Bearbeiten]
<script src="<?php echo AIOM::JS(array('scripts/jquery-2.2.4.min.js','scripts/jquery.chocolat.js','scripts/jquery.fitvids.js','scripts/jquery.flexslider-min.js', 'scripts/main.js')); ?>"></script>
<link rel="stylesheet" type="text/css" href="<?php echo AIOM::CSS('styles/main.less'); ?>">
<?php echo $homepage->site_title .' '. Date('Y'); ?>
Link zur Seite anhand URL-Pfad[Bearbeiten]
<?php echo $pages->get('/ueber-uns/')->url; ?>
Feld einer Seite[Bearbeiten]
$content_left = $page->get('content_left');
Bild[Bearbeiten]
if($page->main_image){$image = $page->main_image->size(640,960);}
else $image = NULL;
Bild von der Homepage[Bearbeiten]
in _init.php
$homepage = $pages->get('/');
im Template
if($homepage->config_logo){$logo = $homepage->config_logo->width(280);}
else $logo = NULL;
[Bearbeiten]
<ul class='nav-list'>
<?php
// Childrens
foreach(($page->children) as $item) {
if($item->id == $page->rootParent->id) {
echo '<li class="current">';
} else {
echo '<li>';
}
echo '<a class="ajax-link" href="'.$item->url.'">'.$item->title.'</a></li>';
}
?>
</ul>
Auflistung mit div. Feldern aus Kindseiten[Bearbeiten]
/**
* Publications list template
*
*/
$publications = '';
$children = $page->children;
foreach($children as $child){
$publications .= '<div class="box">';
$publications .= '<h2><a class="ajax-link" parent="'. $child->parent->title .'" name="'.$child->title.'" href="'. $child->url. '">'. $child->title . '</a></h2>';
$publications .= $child->body;
$publications .= '</div>';
}
$content = $page->body . $publications;
Minigalerie[Bearbeiten]
Thumbnails / Child Pages
$works = '<div class="gallery">';
$children = $page->children;
foreach($children as $child){
$works .= '<a class="ajax-link" parent="'. $child->parent->title .'" name="'.$child->title.'" href="'. $child->url. '">';
$works .= '<h2>'. $child->title . '</h2>';
if(count($child->thumbnail)){
$works .= '<div class="thumbnail"><img src="'. $child->thumbnail->getThumb('thumbnail') .'" title="'. $image->description .'"></div>';
}
$works .= '</a>';
}
$works .= '</div>';
$content = $page->body . $works . '<br/>' . $page->video;
[Bearbeiten]
// add next button if there is another page next
if($page->next->id){
$next = '<div class="next"><i>Next:</i> <a class="ajax-link" name="'.$page->next->title.'" href="'. $page->next->url .'">'. $page->next->title .'<span class="fa fa-arrow-right"><span></a></div>';
}
$content = '<h2>'. $page->title . '</h2>' . $page->body . '<br/><div class="video">' . $page->video .'</div>' . $next;
Simple Gallery with next Page[Bearbeiten]
$gallery = '<div class="gallery">';
$images = $page->gallery;
// add thumbnail to gallery
if(count($page->thumbnail)){
$gallery .= '<a class="chocolat-image gallery-item" href="'.$page->thumbnail->url.'"><img src="'. $page->thumbnail->getThumb('thumbnail') .'" title="'. $image->description .'"></a>';
}
foreach($images as $image){
$gallery .= '<a class="chocolat-image gallery-item" href="'.$image->url.'"><img src="'. $image->getThumb('thumbnail') .'" title="'. $image->description .'"></a> ';
}
$gallery .= '</div>';
// add next button if there is another page next
if($page->next->id){
$next = '<div class="next"><i>Next:</i> <a class="ajax-link" name="'.$page->next->title.'" href="'. $page->next->url .'">'. $page->next->title .'<span class="fa fa-arrow-right"><span></a></div>';
}
$content = '<h2>'. $page->title . '</h2>' . $page->body . '<br/>' . $gallery . '<br/><div class="video">' . $page->video .'</div>'. $next;
Platzhalter-Seite mit Redirect auf erste Unterseite[Bearbeiten]
Möchte man eine Eltern-Seite für das Menü generieren die keinen eigenen Inhalt besitzt sondern nur Unterseiten enthält, kann man ein Template für diese Seite erstellen, dass den User auf die erste Unterseite weiterleitet.
Diese Lösung ist ein regulärer Redirect. Ob das die Beste Lösung ist müßte man mal überlegen. Auf alle Fälle besser als Duplicate Content.
<?php namespace ProcessWire;
$root = $pages->get("/");
if($page->numChildren){
$session->redirect($page->child()->url);
} else $session->redirect($root->url);
?>
In Funktionen auf Page Objekt zugreifen[Bearbeiten]
Entweder als Parameter übergeben (evtl. by reference) oder wenn ein ProcessWire Objekt in der Funktion vorliegt das vom Wire Objekt abgeleitet ist (fast alle) kannst du dieses nutzen:
$page = $items->wire('page'); // $items is a PageArray - use its wire to get current page
