Add function from a plugin to the json model

(@gielcobben)

Hello,

I have added a plugin which adds category images to the normal post category. I would like to output the category image URL to the API as a value. I modified the category.php controller by adding:

var $image;

and by adding the following

function import_wp_object($wp_category) {
    $this->id = (int) $wp_category->term_id;
    $this->slug = $wp_category->slug;
    $this->title = $wp_category->name;
    $this->description = $wp_category->description;
    $this->parent = (int) $wp_category->parent;
    $this->post_count = (int) $wp_category->count;
    // image:
    $this->image = z_taxonomy_image_url($this->id);
  }

I’m having a very similar issue.

I am running WordPress 3.9.2 with a custom theme, and I’ve created a custom API controller. I’m using JSON API 1.1.1 and Categories Images 2.4.2.

At the top of the custom controller I have
include_once(ABSPATH.'wp-admin/includes/plugin.php');

Then I use the following code for the category image:
```
$image = '';
if (function_exists('z_taxonomy_image_url')) $image = z_taxonomy_image_url($category->term_id);
```
I have set this up on a development server and a production one. It works fine in development, but in production the function_exists command is failing.

Re gielcobben’s issue, what error are you encountering? Are you getting a php error such as “call to undefined function” or are you getting a false value returned from the z_taxonomy_image_url function?

Further to my last post, if I use is_plugin_active() to detect the categories-images plugin, it returns false, yet in other parts of my code it returns true.

All I can think is that it is something to do with the JSON API plugin.
