无法回显wpdb结果

Question

I'm pulling information from the WordPress database. It's definitely pulling all the correct information and if I display the information with print_r( $res, true ) it shows what i require which is:

[term_id] => 8 [name] => Africa [slug] => africa [COUNT(a.id)] => 1

I need to echo the COUNT(a.id) but I can't seem to manage this? My full code is here: http://pastie.org/4121409

I have managed to echo all the other information, just not the COUNT(a.id)

Thanks in advance!

Answer 1

When selecting, use column aliases, like this: COUNT(a.id) AS id_count

Then it will appear as the field name in result set, instead of COUNT(a.id) and you will be able to access it by $rs->id_count

Also note that in your original code, line 22 will break the code. It should have been $counter = "COUNT(a.id)";
