https://processwire.com/docs/front-end/front-end-editing/

* Mehrere Optionen (im Backend auswählen)
* Option A -> Automatisch
** Kann verwendet werden wenn ein Feld nur einmal auf einer Seite verwendet wird.
* Option B -> API Method Call
** Geeignet für text fields, number fields, dates...
** Nicht geeignet für Files/Images, PageTables, Repeaters or andere Felder über die man iteriert
** Statt get einfach edit nehmen
 <?php echo $page->edit('body'); ?>
* Option C -> HTML Edit Tags
** Anhand ''<edit [feldname]>...</edit>''  findet PW die Felder
** Für Repeater geeignet
** Unterstüzt Inline Editor, wenn das Feld es unterstützt

* Option D -> HTML Edit Attributes
** Gleiche Funktionalität wie Tags
** edit Attribut für div, span, ... statt eigenständiges Tag
** always uses the dialog editor and does not use the inline editor.
 <div edit="events">...</div>

== Konfiguration ==
* PageFrontEdit Modul installieren (Core)
* Für Option A Checkboxen anhaken
* Für Option B-C Templates berarbeiten.
== Options in Detail ==
=== Option A ===
Einfach im Backend anhaken

=== Option B ===
Statt
 $page->get('field_name');
 $page->edit('field_name');
Beispiel 
 <?php echo $page->edit('body'); ?>
=== Option C ===

Beispiel Image Feld 'photo'
<syntaxhighlight lang="php">
<edit photo>
  <img src="<?=$page->image->url?>" />
</edit>
</syntaxhighlight>

Beispiel Repeater, PageTable oder Table Field
<syntaxhighlight lang="php">
<edit events>
  <?php foreach($page->events as $event): ?>
    <div class="event">
      <h3><?=$event->title?></h3>
      <p class="date"><?=$event->date?></p>
      <p><?=$event->summary?></p>
    </div>
  <?php endforeach; ?>
</edit>
</syntaxhighlight>

Beschreibung von Ryan:

By the way, you can also use some more verbose but alternate syntax for the <edit> tags if you prefer. If your editor does syntax highlighting with your HTML, it may be more consistent (the "quotes" are optional of course):

 <edit field="events"> ... </edit>
If your editable region contains multiple fields you want to be edited together, you can specify more than one:

 <edit field="intro,image,events"> ... </edit>
If your field happens to be on some other page other than the one being rendered, you can also specify what page you want to be edited:

 <edit field="events" page="1001"> ... </edit>
The 1001 can be any page ID or path. The above can also be shortened to this if you prefer:

 <edit field="1001.events"> ... </edit>
Or this:

 <edit 1001.events> ... </edit>
If you are using <edit> tags with a field that supports inline editing (like a text or CKEditor field), the inline editor will be used. Otherwise it will open a dialog to the editor.

=== Option D ===
<syntaxhighlight lang="html5">
<div edit="events">
  <!-- code to output events -->
</div>
</syntaxhighlight>
Or to specify a field from some other page (1001):

<syntaxhighlight lang="html5">
<div edit="1001.events"> ... </div>
</syntaxhighlight>
Or to specify multiple fields:

<syntaxhighlight lang="html5">
<div edit="intro,image,events"> ... </div>
</syntaxhighlight>
The "edit" attributes are stripped from the markup that gets output, so the only place you will see them is where you place them in your template file(s).

Worth noting about '''option D''' is that it '''always uses the dialog editor''' and does not use the inline editor.

== Probleme lösen ==
=== Front Page Editing in Repeatern ===
Der Editor zeigt keinen Inhalt. Bei Superadmins funktioniert es aber.
 https://processwire.com/talk/topic/15357-solved-frontend-edit-on-repeater-fields/
 https://github.com/processwire/processwire-issues/issues/183
Lösung: Mit Option C funktioniert es, wenn man noch das page-Attribut mit reinnimmt. Im page Attribut gibt man den Repeater an.
<syntaxhighlight lang="php">
foreach($page->repeater_field as $item) {
  echo "<h3><edit field='title' page='$item'>$item->title</edit></h3>";
  echo "<edit field='body' page='$item'>$item->body</edit>";
}
</syntaxhighlight>

Manchmal auch praktisch wenn man mit fields arbeitet:
<syntaxhighlight lang="php">
// Body
if($page->body){
  $bodyMarkup = "<edit field=\"body\" page=\"$page\">$page->body</edit>";
}
</syntaxhighlight>

Noch ein Kopierschnipsel:
 <edit field="body" page="'.$page.'">'.$page->body.'</edit>
