Get front-end editable output for field (requires PageFrontEdit module to be installed)
This method requires the core PageFrontEdit
module to be installed. If it is not installed then
it returns expected output but it is not front-end editable. This method corresponds to front-end
editing Option B. See the front-end editor docs for more details. If the user does not have permission to front-end edit then returned output will not be editable.
Use $page->edit('field_name');
instead of $page->get('field_name');
to automatically return an editable
field value when the user is allowed to edit, or a regular field value when not. When field is
editable, hovering the value shows a different icon. The user must double-click the area to edit.
The 2nd and 3rd arguments are typically used only if you need to override the default presentation of the editor or provide some kind of action or button to trigger the editor. It might also be useful if
the content to edit is not visible by default. It is recommended that you specify boolean true for the
$modal
argument when using the $markup
argument, which makes it open the editor in a modal window, less likely to interfere with your front-end layout.
Available since version 3.0.0. This method is added by a hook in PageFrontEdit and only shown in this class for documentation purposes.
Example
// retrieve editable value if field_name is editable, or just value if not
$value = $page->edit('field_name');
Usage
// basic usage
$string = $page->edit();
// usage with all arguments
$string = $page->edit($key = null, $markup = null, $modal = null);
Arguments

Return value
string

Hooking $page->edit(…)
You can add your own hook events that are executed either before or after the $page
method is executed. Examples of both are included below. A good place for hook code such as this is in your /site/ready.php file.
Hooking before
The 'before' hooks are called immediately before each $page
method call is executed. This type of hook is especially useful for modifying arguments before they are sent to the method.
$this->addHookBefore('Page::edit', function(HookEvent $event) {
// Get the object the event occurred on, if needed
$page = $event->object;
// Get values of arguments sent to hook (and optionally modify them)
$key = $event->arguments(0);
$markup = $event->arguments(1);
$modal = $event->arguments(2);
/* Your code here, perhaps modifying arguments */
// Populate back arguments (if you have modified them)
$event->arguments(0, $key);
$event->arguments(1, $markup);
$event->arguments(2, $modal);
});
Hooking after
The 'after' hooks are called immediately after each $page
method call is executed. This type of hook is especially useful for modifying the value that was returned by the method call.
$this->addHookAfter('Page::edit', function(HookEvent $event) {
// Get the object the event occurred on, if needed
$page = $event->object;
// An 'after' hook can retrieve and/or modify the return value
$return = $event->return;
// Get values of arguments sent to hook (if needed)
$key = $event->arguments(0);
$markup = $event->arguments(1);
$modal = $event->arguments(2);
/* Your code here, perhaps modifying the return value */
// Populate back return value, if you have modified it
$event->return = $return;
});
