This plugin provides custom functions needed for the Continuing Education website to be integrated with our main WordPress website. It also provides a widget that can be used to display posts linked to a CustomPress custom post type using CustomPress taxonomy.

After activation, settings for the plugin can be updated via a submenu "CE Custom Functions" under the main administrative Settings menu. Available settings:

• CampusCE data URL - The URL used to retrieve CampusCE data
• CampusCE user key - The special user key that is required to use the data URL
• CustomPress post type - The post type created in CustomPress plugin.
• CustomPress taxonomy - The taxonomy created in CustomPress plugin.
• CustomPress field ID - The field ID created in CustomPress plugin.

Prior to version 2.0, this plugin used CustomPress to manage Custom Post Types, Taxonomies, and Fields.

• In CustomPress settings, delete the Post Type and Taxonomy
• Take a note of the Custom Field name- should be something like _ct_text_562fe946ccfcd
• Delete the Custom Field, making sure not to delete data.
• Follow the instructions in Setup (below).
• Double check that the Advanced Custom Field name matches the the field name you took a note of before
• Deactivate/Remove CustomPress

• Activate Plugin (Single Site)
• Install Advanced Custom Fields from the WordPress plugin repository
  • Go to Custom Fields -> Tools.
  • In the Import Field Groups area, select file, and navigate to the acf-ce-fields.json file in this repo
  • Import
• Go to Settings -> CE Custom Functions
  • Define your Data URL and User Key with data from CampusCE
  • Post Type should be set to ceprograms
  • Taxonomy should be set to ce_program_cross_ref
  • Field ID should be set to _ct_text_562fe946ccfcd

All return an object generated from the data XML as returned from CampusCE. All are static methods of the plugin's CE_Custom_Functions class.

Note: The functions now distinguish between courses and classes. Per the data, classes are an offering of a course. As such, pulling classes will return all available offerings of a course.

  Returns array of course objects. Course object contains CourseID, Title, WebDescr, CategoryID, and NewTag data members.

• cecf_get_classes_by_category_id($category_id)

• cecf_get_category_by_id($category_id)
