gfpdf_settings_tools
Jump To Section
Description
This filter can be used to add new fields to the Tools tab of the Gravity PDF settings page. It's basically a Fields API and all validation, sanitising and saving is handled automatically for you.
The Tools tab doesn't have a submit button like other pages. This page is specifically for action tasks like Setup Custom Templates. If you want to add a new action you should include a new form button and do your processing from the gfpdf_tool_tab_actions action.
Parameters
$fields | array : An associative array that includes a breakdown of the field information. We go into more detail about what each field configuration setting does in our custom PDF configuration guide.
Usage
The following snippet shows you how to add a new button to the Tools tab. Remember, when adding new buttons you also need to do your processing in the gfpdf_tool_tab_actions action.
add_filter( 'gfpdf_settings_tools', function( $fields ) {
/**
* Ensure you prefix the array key and ID to prevent any conflicts
*/
/* Add a colour picker to the Security section of the General Settings page */
$fields['prefix_flush_logs'] = array(
'id' => 'prefix_flush_logs',
'name' => __('Flush Logs', 'prefix-text-domain' ),
'type' => 'button',
'desc' => __('Deletes all existing Gravity PDF log files', 'prefix-text-domain' ),
'std' => __( 'Purge', 'prefix-text-domain' ),
);
return $fields;
} );
The following snippet shows you how to change the label of an existing field:
add_filter( 'gfpdf_settings_tools', function( $fields ) {
if ( isset( $fields['setup_templates'] ) ) {
$fields['setup_templates']['name'] = __( 'Install Custom Templates', 'prefix-text-domain' );
}
return $fields;
} );
