Description

Implement [bw_option] shortcode to display the value for an option field

WordPress stores option fields in the wp_options table. They can either be simple fields or more complex such as serialised fields. In my development database there are over 1300 option fields! We wouldn't want a shortcode for each different option_name I wonder what percentage can be displayed using this shortcode?

This shortcode allows certain option fields to be displayed. It uses oik-fields technology for formatting ? so should this be in oik-fields? Should this shortcode also allow the field to be set? If so, how do we reset it after use? Example:

[bw_option bw_css_options.bw_autop checkbox] 

If the field is serialized then get_option will return an array. So we need to detect this, rather than use oik-fields.

Example

[bw_option wpseo_xml serialized] 

Passing a type of serialized is unnecessary in this case. The dot notation could also return an array.

Usage

$string = bw_option( $atts, $content, $tag );

Parameters

$atts

( array ) optional – shortcode parameters

$content

( string ) optional – not expected… but it could be the title

$tag

( string ) optional – the shortcode

Returns

string the generated HTML
