Question

Why does this code fail to display the category name ‘Apples’ using the current WordPress taxonomy system? The Category names are stored in the $wpdb->terms table (wp_terms).

<?php  $ra_category_id = 3;  $ra_category = $wpdb->get_results('SELECT name FROM $wpdb->terms WHERE term_id = '3''); $ra_category_name = $ra_category->name;           ?>  <h3>Category: <?php echo $ra_category_name; ?></h3> 

The table rows are

term_id     name              slug          term_group 1         Uncategorized     uncategorized   0 2         Blogroll          blogroll        0 3         Apples            apples          0 4         Bananas           bananas         0 

Answer 1

$ra_category is the following array:

array(1) {   [0]=>   object(stdClass)(1) {     ['name']=>     string(8) 'Apples'   } } 

So what you want is:

$ra_category_name = $ra_category[0]->name; 

When dealing with query results, always check the whole result with a var_dump(), it helps.

(note that you’re also using $ra_category_id but then hardcoding the value ‘3’ in your query)
