这是我的代码：

 $config = array(
    \'id\' => \'tax_meta_box\',          // meta box id, unique per meta box
    \'title\' => \'Tax Meta Box\',          // meta box title
    \'pages\' => array(\'category\'),        // taxonomy name, accept categories, post_tag and custom taxonomies
    \'context\' => \'normal\',            // where the meta box appear: normal (default), advanced, side; optional
    \'fields\' => array(),            // list of meta fields (can be added by field arrays)
    \'local_images\' => false,          // Use local or hosted images (meta box images for add/remove)
    \'use_with_theme\' => get_template_directory_uri() . \'/Tax-Meta-Class/Tax-meta-class\'          
  );
  /*
   * Initiate your meta box
   */
  $my_meta =  new Tax_Meta_Class($config);
  //Image field
  $my_meta->addImage(\'image_field\',array(\'name\'=> __(\'My Image \',\'tax-meta\')));

  $my_meta->Finish();

<?php $terms = get_terms( \'category\' );
            foreach($terms as $p_cat):
                $term_id = $p_cat->term_id;
                $saved_data = get_tax_meta($term_id,\'image_field\',true);
                echo \'<pre>\';
                echo $term_id; // Echoes \'1\' which is the category ID
                echo $saved_data; // Doesn\'t show anything . Wonder Why!!
                exit;

                ?>
