PHP Form: Select Categories

    Refining my options panel and I want to offer the user the option to select certain categories from a drop down. This works – and even saves. However after the save the drop down list doesn’t “remember” the selection and if you save again changes are lost.

    <select class="aselect" id="<?php echo $value['id']; ?>"  name="<?php echo $value['id']; ?>">
	<option value="0"><?php _e('Select a Category', 'thetimes'); ?></option>
		<?php	global $options;
					foreach ($options as $value) {
						if (get_settings( $value['id'] ) === FALSE) { $$value['id'] = $value['std']; } else { $$value['id'] = get_settings( $value['id'] );
						}
					}

					$categories = &get_categories('type=post&orderby=name&hide_empty=1');

					if ($categories) {
						$find_select = $tt_catbox_1;

						foreach ($categories as $category) {
							$selected = (in_array($category->cat_ID, $find_select)) ? ' selected="selected"' : '';
							echo '<option value="' . $category->cat_ID . '"' . $selected . '>' . $category->cat_name . '</option>' . "\n";
						}
					}
		?>
</select>

    $tt_catbox_1 contains the category ID

    I’ve Googled and found the above code, however I can’t get the “SELECTED” to work quite right. I think I need to pull from the database the settings. How do I do that?

    Solved it…

    <select class="aselect" id="<?php echo $value['id']; ?>"  name="<?php echo $value['id']; ?>">
			<?php
				global $options;
					foreach ($options as $value) {
						if (get_settings( $value['id'] ) === FALSE) { $$value['id'] = $value['std']; } else { $$value['id'] = get_settings( $value['id'] );
						}
					}
				$cats = get_categories('hide_empty=0'); foreach($cats as $cat) { ?>
				<option value="<?php echo $cat->cat_ID; ?>"<?php selected($tt_catbox_1, $cat->cat_ID); ?>><?php echo $cat->cat_name; ?></option>
				<?php } ?>
</select>

    You have done a great job. Have you solved it yourself? I’m usually using php form tutorials in such cases.
