fetch categories for theme options WordPress
- SOLVED
Hi,
Based on this: http://themeshaper.com/sample-theme-options/
The dropdown box is populated in a static way. I want to populate the dropdown with categories.
I changed the code to get_categories, but the selected item is not saved.
basically, I need to adapt this code because I want the user of the theme to select a category for the homepage slider.

wp_dropdown_categories()

I did use that function to populate the dropdown, but $selected is always NULL
Oleg Butuzov comments:
if you are saving somethere data from the update - its should be inside options.
by default you can use get_option('default_category')
after save it depands on your settings that's is saved.

i think will be better to debug where is select saves. i am not sure you a really saving the values from the dropdown_categories.

wp has a function to do that.
$selected = 'xxx'; //it is your current value
wp_dropdown_categories('name=objname&selected='.$selected);

Monster Coder comments:
you have to populate the $selected value from your storage. if it is stored in database, fetch it before calling the function. if it is stored in wordpress option table, use get_option().
otherwise, put your code so experts can help you better.
paul de wouters comments:
$selected = $options['selectinput']; wp_dropdown_categories('name=sample_theme_options[selectinput]&selected='.$selected);
the rest of the code is unchanged. See attached file or http://themeshaper.com/sample-theme-options/
the $options variable gets populated after the submit. the other values are populated correctly.
