How to parse row results from $wpdb -> get_results

Question

I have the following:

$query = 'SELECT * FROM wp_pod_tbl_add_questions WHERE id LIKE '. $id;

                                        $row = $wpdb -> get_results($query);

How do I get the columns named 'id' and 'name' from $row?

Answer 1

foreach( $wpdb->get_results("SELECT * FROM your_table_name WHERE id LIKE' . $id . ';") as $key => $row) {
// each column in your row will be accessible like this
$my_column = $row->column_name;}

Always Try the WordPress Codex: http://codex.wordpress.org/Class_Reference/wpdb#SELECT_Generic_Results

Essentially given the default syntax, the variable $row here is an object containing your results. You could alternately specify the TYPE of result (numeric array, associative array).

Assuming just one result, then $row->id and $row->name should give you the information.

If you get back more than one result, you'd want to loop over the entries in the object.

If you are expecting just one row back, then try using $wpdb->get_row http://codex.wordpress.org/Class_Reference/wpdb#SELECT_a_Row
