Can't get wp_dropdown_categories to work inside plugin
I managed to create an external page that shows a drop-down of all my categories inside my custom taxonomy called Frequencies that the user can select. The code is as simple as this (scrape.php):
<?php define( 'WP_USE_THEMES', false ); require( '../wp-load.php' ); // delete the above two lines when using as plugin ?> <?php wp_dropdown_categories(array( 'child_of' => 0, 'class' => 'postform', 'depth' => 0, 'echo' => 1, 'exclude' => '', 'hide_empty' => false, 'hide_if_empty' => false, 'hierarchical' => true, 'id' => '', 'name' => 'cat-dropdown', 'order' => 'ASC', 'orderby' => 'name', 'selected' => 0, 'show_count' => 0, 'show_option_all' => '', 'show_option_none' => __('None'), 'tab_index' => 0, 'taxonomy' => 'frequency', )); ?>
The above displays the following options:
Now, I want to CONVERT the above into doing the same thing, but within the context of a plugin. The idea is the plugin asks the user to select a category and press submit to go to an options page.
So far I have created an admin.php page that contains the following:
<?php include(plugin_dir_path(__FILE__).'scrape.php'); ?>
So I have the plugin that displays a dropdown, but the dropdown only contains ONE option rather than displaying all the categories available under the taxonomy.
The output it as follows:
So the question is, what happens to the other 2 options?
