Hi Everett!
I'm trying to implement a new custom field type (eventually this will be part of a project to integrate popcornmaker into WordPress -- cf. http;//popcorn.webmaker.org). For now I have just copied the simplest case I could find -- the contents of fields/text.php -- into the functions.php of my theme. I've them made trivial find/replace substitions, but my new field type doesn't show up in the list at admin.php?page=cctm_fields&a=list_custom_field_types
Any hints? Thanks as always for my favorite plugin! Here's the code from functions.php:
include_once ( CCTM_PATH . '/includes/CCTM.php');
include_once ( CCTM_PATH . '/includes/CCTM_FormElement.php');
class CCTM_popcorn extends CCTM_FormElement
{
public $props = array(
'label' => '',
'name' => '',
'description' => '',
'class' => '',
'extra' => '',
'default_value' => '',
'is_repeatable' => '',
'output_filter' => '',
'required' => '',
// 'type' => '', // auto-populated: the name of the class, minus the CCTM_ prefix.
);
//------------------------------------------------------------------------------
/**
* This function provides a name for this type of field. This should return plain
* popcorn (no HTML). The returned value should be localized using the __() function.
*
* @return string
*/
public function get_name() {
return __('Popcorn', CCTM_TXTDOMAIN);
}
//------------------------------------------------------------------------------
/**
* This function gives a description of this type of field so users will know
* whether or not they want to add this type of field to their custom content
* type. The returned value should be localized using the __() function.
*
* @return string popcorn description
*/
public function get_description() {
return __('Popcorn fields implement the standard <input="popcorn"> element. "Extra" parameters, e.g. "size" can be specified in the definition.', CCTM_TXTDOMAIN);
}
//------------------------------------------------------------------------------
/**
* This function should return the URL where users can read more information about
* the type of field that they want to add to their post_type. The string may
* be localized using __() if necessary (e.g. for language-specific pages)
*
* @return string e.g. http://www.yoursite.com/some/page.html
