Layout Class

Calling the Layout Class

Calling the Layout Class

class Layout

Administrators may extensively customize publish pages on a per member role and per channel basis. Since these custom layouts are saved as a serialized array in the database, any additions or deletions to publish page tabs and fields must be synced to any saved layouts. The control panel library provides 4 methods to facilitate custom layout updates.

ee()->load->library('layout');

Add Tabs

`add_layout_tabs([$tabs = array()[, $namespace = ''[, $channel_id = array()]]])`

Parameter	Type	Description
$tabs	`Array`	Associative nested array with the top level where the key is the name of the tab. All fields are represented as nested arrays within the initial array (see below)
$namespace	`String`	Namespace of the add-on
$channel_id	`Mixed`	Limits the channels affected to a single channel ID or array of channel IDs
Returns	`Void`

Adds tabs and any associated fields to currently saved publish layouts. If there is an existing tab with the same name, the method will return false:

ee()->layout->add_layout_tabs($tabs);

$tabs must be an associative array where the top level array(s) is the name of the tab. If the tab contains any fields, as it likely does, include them as elements of their tab’s array, with the field name as a key and containing the required elements: visible, collapse, htmlbuttons and width:

$tabs['pages'] = array(
    'pages_uri' => array(
        'visible'     => 'true',
        'collapse'    => 'false',
        'htmlbuttons' => 'true',
        'width'       => '100%'
    ),
    'pages_template_id' => array(
        'visible'     => 'true',
        'collapse'    => 'false',
        'htmlbuttons' => 'true',
        'width'       => '100%'
    )
);

Delete Tabs

`delete_layout_tabs([$tabs = array()[, $namespace = ''[, $channel_id = array()]]])`

Parameter	Type	Description
$tabs	`Array`	Associative nested array with the top level where the key is the name of the tab. All fields are represented as nested arrays within the initial array (see above)
$namespace	`String`	Namespace of the add-on
$channel_id	`Mixed`	Limits the channels affected to a single channel ID or array of channel IDs
Returns	`Mixed`	`TRUE` if successful, otherwise an array of errors

This method will remove tabs and all associated fields from the saved publish page layouts. The $tabs variable must be an associative array, with the top level array’s key the name of the tab. As in the Layout::add_layout_tabs method, any associated fields should be included as keys within the tab’s array:

ee()->layout->delete_layout_tabs($tabs);

Add Fields

`add_layout_fields([$tabs = array()[, $channel_id = array()]])`

Parameter	Type	Description
$tabs	`Array`	Associative nested array with the top level where the key is the name of the tab. All fields are represented as nested arrays within the initial array (see above)
$channel_id	`Mixed`	Limits the channels affected to a single channel ID or array of channel IDs
Returns	`Mixed`	`TRUE` if successful, otherwise an array of errors

Used to add new fields to an already existing tab. Because custom layouts may have moved the field(s) to a different tab and deleted the tab originally associated with the fields, a new tab will be created if none exists in the layout. The $tabs array takes the same format as the Layout::add_layout_tabs method:

ee()->layout->add_layout_fields($tabs, $channel_id);

Delete Fields

`delete_layout_fields([$tabs = array()[, $channel_id = array()]])`

Parameter	Type	Description
$tabs	`Array`	Associative nested array with the top level where the key is the name of the tab. All fields are represented as nested arrays within the initial array (see above)
$channel_id	`Mixed`	Limits the channels affected to a single channel ID or array of channel IDs
Returns	`Mixed`	`TRUE` if successful, otherwise an array of errors

Used to delete fields without removing the existing tab. This method removes all matching field names from the saved layouts, regardless of the tab they are currently saved in. The $tabs array takes the same format as the Layout::add_layout_tabs method, while $channel_id is an optional parameter that limits the update to layouts associated with a given channel and should generally be omitted from third party usage.

ee()->layout->delete_layout_fields($tabs, $channel_id);
