    <p>I am using a mysqli prepare statement to query my db with multiple constraints. I have ran the code in a test file of mine and it works perfectly fine. However, when I move the code over to my live file it throws the error below:</p> <blockquote> <p>PHP Warning: mysqli_stmt::bind_result(): Number of bind variables doesn't match number of fields in prepared statement in C:\wamp\www\firecom\firecom.php on line 80</p> <p>PHP Notice: Undefined variable: results in C:\wamp\www\firecom\firecom.php on line 89</p> </blockquote> <p>Both parameters are being set correctly but something is throwing it off.</p> <p>Code: </p> <pre><code>$query = $mysqli-&gt;prepare("SELECT * FROM calls WHERE wcccanumber = ? &amp;&amp; county = ?"); $query-&gt;bind_param("ss", $wcccanumber, $county); $query-&gt;execute(); $meta = $query-&gt;result_metadata(); while ($field = $meta-&gt;fetch_field()) { $parameters[] = &amp;$row[$field-&gt;name]; } call_user_func_array(array($query, 'bind_result'), $parameters); while ($query-&gt;fetch()) { foreach($row as $key =&gt; $val) { $x[$key] = $val; } $results[] = $x; } print_r($results['0']); </code></pre> <p>$query var_dump:</p> <pre><code>object(mysqli_stmt)#27 (10) { ["affected_rows"]=&gt; int(-1) ["insert_id"]=&gt; int(0) ["num_rows"]=&gt; int(0) ["param_count"]=&gt; int(2) ["field_count"]=&gt; int(13) ["errno"]=&gt; int(0) ["error"]=&gt; string(0) "" ["error_list"]=&gt; array(0) { } ["sqlstate"]=&gt; string(5) "00000" ["id"]=&gt; int(1) } </code></pre>

    1. COcan you use && in an sql query? i thought it was AND inside a WHERE clause. try SELECT * FROM calls WHERE wcccanumber = ? AND county = ?

    2. CO@JeffHawthorne Actually, `&&` is a synonym to AND in mysql: http://dev.mysql.com/doc/refman/5.0/en/logical-operators.html#operator_and

    3. COThe `$results` warning is easy -- The server is checking for undefined variables and your local one isn't. Define `$results` before the `while($query->fetch())` loop and it will go away.

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.
