Class MLA (Media Library Assistant) Custom Fields List Table implements the "Custom Fields" admin settings submenu table
Extends the core WP_List_Table class.
$default_columns : array
Table column definitions
This array defines table columns and titles where the key is the column slug (and class) and the value is the column's title text.
All of the columns are added to this array by MLA_Custom_Fields_List_Table::_localize_default_columns_array.
$default_hidden_columns : array
Default values for hidden columns
This array is used when the user-level option is not set, i.e., the user has not altered the selection of hidden columns.
The value on the right-hand side must match the column slug, e.g., array(0 => 'ID_parent, 1 => 'title_name').
$default_sortable_columns : array
Sortable column definitions
This array defines the table columns that can be sorted. The array key is the column slug that needs to be sortable, and the value is database column to sort by. Often, the key and value will be the same, but this is not always the case (as the value is a column name from the database, not the list table).
The array value also contains a boolean which is 'true' if the initial sort order for the column is DESC/Descending.
mla_submenu_arguments(boolean $include_filters = true) : array
Process $_REQUEST, building $submenu_arguments
| boolean | $include_filters | Optional. Include the "click filter" values in the results. Default true. |
non-empty view, search, filter and sort arguments
mla_manage_hidden_columns_filter( $result, $option, $user_data) : array
Handler for filter 'get_user_option_managesettings_page_mla-settings-menu-custom_fieldcolumnshidden'
Required because the screen.php get_hidden_columns function only uses the get_user_option result. Set when the file is loaded because the object is not created in time for the call from screen.php.
| $result | ||
| $option | ||
| $user_data |
updated list of hidden columns
mla_manage_columns_filter() : array
Handler for filter 'manage_settings_page_mla-settings-menu_columns'
This required filter dictates the table's columns and titles. Set when the file is loaded because the list_table object isn't created in time to affect the "screen options" setup.
list of table columns
column_default( $item, $column_name) : string
Supply a column value if no column-specific function has been defined
Called when the parent class can't find a method specifically built for a given column. All columns should have a specific method, so this function returns a troubleshooting message.
| $item | ||
| $column_name |
Text or HTML to be placed inside the column
_get_view(string $view_slug, array $custom_field_item, string $current_view) : string
Returns HTML markup for one view that can be used with this table
| string | $view_slug | View slug |
| array | $custom_field_item | count and labels for the View |
| string | $current_view | Slug for current view |
| false HTML for link to display the view, false if count = zero
mla_get_custom_field_status_dropdown(string $selected = 'any') : string
Get dropdown box of rule status values, i.e., Active/Inactive.
| string | $selected | Optional. Currently selected status. Default 'any'. |
HTML markup for dropdown box.
prepare_items() : void
Prepares the list of items for displaying
This is where you prepare your data for display. This method will usually be used to query the database, sort and filter the data, and generally get it ready to be displayed. At a minimum, we should set $this->items and $this->set_pagination_args().
handle_row_actions(object $item, string $column_name, string $primary) : string
Generate and display row actions links.
| object | $item | Attachment being acted upon. |
| string | $column_name | Current column name. |
| string | $primary | Primary column name. |
Row actions output for media attachments.
