getCMSFields

This is the method you need to call to add / remove / edit fields in the CMS. For a tutorial on how to add your own fields to the CMS see tutorial 2 which covers how to add fields to your page types

// add a another textbox under the Content tab
$fields->addFieldToTab("Root.Content", new TextField("ExtraContent", "Extra Content"));
 
// Make a new tab 'BioPic' and add a image field
$fields->addFieldToTab("Root.BioPic", new ImageField("Picture", "Staff Photo"));

// remove the content text area 
$fields->removeFieldFromTab("Root.Content.Main","Content");
 
// remove the whole reports tab
$fields->removeFieldFromTab("Root","Reports");

// Don't like the title for 'Content'?
$fields->renameField("Content", "A better Title for Content");
