Template files for CCK fields

Theming Constructed Content Types

After you have designed your content, you will likely want to lay out the presentation of the content. This is most easily done with PHPtemplate-based themes. There are two basic options for theming your content, depending on the level of control you need to exert.

Theming individual fields

This method is straightforward and allows for sensible defaults, but requires a modest amount of setup. Place the "field.tpl.php" and "template.php" files found in the theme folder of the CCK download in your theme's folder. If you already have a "template.php" file, you will need to append the code in this one to your own.

All fields are now rendered using your "field.tpl.php" template. If you want to change them all the same way (for example, to hide every field label), you can make alterations to this file. If you want to change the presentation of one field independently, you should instead make a copy of this file first, and give it the name "field-field_foo.tpl.php" where "field_foo" is the field name as listed on the administration page. Changes you make to this file will be reflected only in that field.

An $items variable is made available to you in your field template. This contains the content of the field you are rendering. It is always an array, so that the syntax is consistent whether or not the field allows for multiple values. Each item has a "view" property that contains the filtered, formatted contents of the item. You should always use this property in your display for security reasons, unless you are very familiar with how to properly process output and avoid scripting exploits.

The included example here ("field-field_my_field.tpl.php") illustrates a minimalistic approach to field theming, for a single-valued field. For a more flexible template, start from the "field.tpl.php" included in the theme folder of the CCK download.

Available variables in field templates :
$items : an array containg the values of the field.
$items[n]['view'] contains the ready-to-use, filtered, formatted value
$label : the label of the field
$label_display : the display settings for the label ('hidden', 'above', or 'inline')
$field_empty : TRUE if there is nothing to display in the field
$field_type : the type of the field,
$field_name : the name of the field,
$field_type_css : same as above, with '-' signs replaced with '_' for use in css properties
$field_name_css : same as above, with '-' signs replaced with '_' for use in css properties
$field : an array containing the full CCK field object
