Body
I have the following code: <pre><code>function av_connections_search($string){ global $wpdb; // remove url parameter from string $string = trim($string,'s='); $search = explode('%20',$string); // query the wp_connections database table according to search entry $sql = " SELECT * FROM {$wpdb->prefix}connections WHERE contact_first_name IN (".implode(', ', array_fill(0, count($search), '%s')).") "; // prepare() to prevent sql injection $query = call_user_func_array(array($wpdb, 'prepare'), array_merge(array($sql), $search)); // get query results //var_dump($query); $results = $wpdb->get_results($query); // return if no results if(empty($results)){ return false; } // flush $wpdb cache $wpdb->flush(); // return data to search.php return $results; } </code></pre> where <code>$string</code> looks like ?s=search+these+terms when passed to the function My question, how can I use multiple WHERE statements? I've tried simply: <pre><code>WHERE contact_first_name IN (".implode(', ', array_fill(0, count($search), '%s')).") OR contact_last_name IN (".implode(', ', array_fill(0, count($search), '%s')).") </code></pre> but it fails completely. When I do: <pre><code>WHERE contact_first_name OR contact_last_name IN (".implode(', ', array_fill(0, count($search), '%s')).") </code></pre> it only returns <code>contact_last_name</code>. What am I missing? EDIT: Ok, so I'm quite sure the problem lies within this: <code>$query = call_user_func_array(array($wpdb, 'prepare'), array_merge(array($sql), $search));</code> but, for a lack of sleep I cannot wrap my mind around why it's not merging the array with both WHERE clauses. EDIT 2 Should this not work? It works great if I use the single WHERE clause, but the moment I use OR and another clause, it returns nothing, which makes no sense because this is the query: <code>SELECT * FROM wp_connections WHERE</code>contact_first_name<code>IN (%s, %s) OR</code>contact_last_name<code>IN (%s, %s) " [1]=> string(4) "Mina" [2]=> string(5) "Morse"</code> EDIT 3 I do not believe prepare() is the problem. Consider this (doesn't work): <pre><code>global $wpdb; $string = trim($string,'s='); $search = explode('%20',$string); $how_many = count($search); $placeholders = array_fill(0, $how_many, '%s'); $format = implode(', ', $placeholders); $query = "SELECT * FROM wp_connections WHERE contact_first_name IN($format) OR contact_last_name IN($format)"; $results = $wpdb->query($query, $search); return $results; </code></pre> Even removing prepare completely, same result. What am I missing? If I remove the <code>OR</code> condition and just check one value, it works fine, but OR kills the query. EDIT 4 It turns out this was the solution: <pre><code>$results = $wpdb->query($query, $search, $search); </code></pre> I was missing the second $search variable... *scratching head still

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
