[bw_field] Display custom fields on the page, without labels or separators

[bw_fields] Display custom fields on the page, with labels and separators

[bw_related]

Display related content. Uses the field definition to determine the search criteria. Works for both noderef type fields and date fields ( using oik-dates ) Now supports the format= parameter to display results using the same logic as [bw_pages] When format=T then it displays results using the same logic as [bw_table]

Actions and filter hooks

Invokes - calls using do_action() or apply_filters()

• oik_fields_loaded

The [bw_new] shortcode invokes the following filters:

• "bw_field_validation_${field_type}"
• "bw_field_validation_${field}"
• "bw_validate_functions"
• "oik_add_new_${post_type}"
• "oik_add_new_format_${post_type}"
• "oik_add_new_fields_${post_type}"
• "oik_set_spam_fields_${post_type}"
• "bw_form_functions", $fields );

The [bw_related] shortcode invokes the following filters:

• "oik_default_meta_value_${field_type}"

Implements - ie. responds to

• "oik_default_meta_value_noderef" - determine the default meta_value for a noderef field type
• "oik_fields_loaded" - define some standard virtual fields
• the rest tbc

Fields displayed by default

Fields are displayed by default in both forms and [bw_fields] displays. You can control these using two values in the options array

'#theme' => false - if you don't want the field displayed by [bw_fields] '#form' => false - if you don't want the form field displayed by [bw_new]

If you don't want the field's label to be displayed by [bw_fields] add: '#label' => false

Frequently Asked Questions

Where is the FAQ?

oik FAQ

What are ._field_name and _node_ref?

For the tag= and category_name= parameters, the code for the [bw_related] shortcode will lookup the current value for the specified field and pass this as the value for the tag or category slug.

• Use ._field_name when the field is directly attached to the current post.
• Use _node_ref._field_name when the field is attached to the post referenced by the _node_ref field.

Can I use _node_ref._field_ref with [bw_fields]

Not yet. But supporting 'fieldref' fields ( field references aka field type 'fieldref') is a planned enhancement.
