    <p>To start, your code that generates the <em>year</em> fields has a nice syntax error:</p> <pre><code>"SUM(IF(c.datecreated='".$year."',IF(LOWER(c.fullTimeEployeeType)='basic hour rate', c.fullTimeEployeeTypeAmount*2080 , c.fullTimeEployeeTypeAmount),0) ".$year."," </code></pre> <p>The <code>SUM(</code> opening statement is missing a closing parentheses. On top of that, you have a floating <code>".$year."</code> that isn't part of any of the enclosed methods (though, it could be used as an alias; I'm not used to seeing it without a preceeding <code>AS</code> though - so this could be my mistake). To take a guess, I would say to replace the <code>".$year."</code> with a <code>)</code> and that should fix that part:</p> <pre><code>$concatYear .= "SUM(IF(c.datecreated='".$year."',IF(LOWER(c.fullTimeEployeeType)='basic hour rate', c.fullTimeEployeeTypeAmount*2080 , c.fullTimeEployeeTypeAmount),0)),"; </code></pre> <p>If the <code>$year</code> addition is in fact to be an alias, you could add the closing parentheses immediately before it to close the <code>SUM()</code> function.</p> <p>Regarding dynamically binding the variables, my ideal solution actually comes from <a href="https://stackoverflow.com/questions/5300365/dynamically-bind-mysqli-stmt-parameters-and-then-bind-result-php">a similar question/answer</a> on SO (this is a direct copy/paste and I take no credit for it, but I do like it =P):</p> <pre><code> // Get metadata for field names $meta = $stmt-&gt;result_metadata(); // This is the tricky bit dynamically creating an array of variables to use // to bind the results while ($field = $meta-&gt;fetch_field()) { $var = $field-&gt;name; $$var = null; $fields[$var] = &amp;$$var; } // Bind Results call_user_func_array(array($stmt,'bind_result'),$fields); // Fetch Results $i = 0; while ($stmt-&gt;fetch()) { $results[$i] = array(); foreach($fields as $k =&gt; $v) $results[$i][$k] = $v; $i++; } </code></pre>

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.
