Use image from taxonomy term as exposed filter option

Question

I created a view which has an exposed filter for taxonomy terms. Now the next step is to theme the options. I tried the module "Better exposed Filters" but I wasn't satisfied. I would like to have images to click on instead the standard filter. I already have stored the images in the taxonomy fields, so every term has it own image.

I tried to create a template file for the filter, but I don't have any access to the fields, where the image is stored. I could do some hardcoded stuff, but I want it as generic as possible.

Has anyone an idea how to achieve it?

Answer 1

Use "Better exposed Filters" and choose its Display setting as Checkbox
Now you have to do form alter like this

function THEMENAME_form_views_exposed_form_alter(&$form, &$form_state) {
  foreach ($form['TAXONOMY_ELEMENT']['#options'] as $tid => &$name) {
      $term = taxonomy_term_load($tid);
      $name = '<img src="' . file_create_url($term->IMAGE_FIELD_NAME['und'][0]['uri']) . '" />';
  }
}

In my case ::
TAXONOMY_ELEMENT = field_type_tid
IMAGE_FIELD_NAME = field_term_image
