    <p>I have a webpage which sends a query to my MySQL database to retrieve information about my company's suppliers and echos the results (all fine so far). It then makes a second query to check if there are any known contacts associated with that supplier:</p> <pre><code>while ($row = mysqli_fetch_array($result)) { $contact = $row["contact"]; echo $row["name"] . "&lt;br&gt;" . $row["category"] . "&lt;br&gt;" . "Telephone: " . $row["telephone"] . "&lt;br&gt;" . "Fax: " . $row["fax"] . "&lt;br&gt;" . $row["email"] . "&lt;br&gt;" . $row["address"] . "&lt;br&gt;" . $row["postcode"] . "&lt;br&gt;&lt;br&gt;" . "Contact: " . $contact . "&lt;br&gt;"; $resultContact = mysqli_query($con,"SELECT * FROM contacts WHERE name = '$contact'"); while($rowContact = mysqli_fetch_array($resultContact)) { echo $rowContact["telephone"] . "&lt;br&gt;" . $rowContact["email"]; echo "&lt;br&gt;"; } } </code></pre> <p>(<code>$row</code> is from the first query and works.) However, <code>echo $rowContact["telephone"] . "&lt;br&gt;" . $rowContact["email"];</code> just prints whitespace.</p> <p>Thanks</p> <p><strong>EDIT:</strong> if I use a string literal in the Where clause, it works as it should. However, I used variables in exactly the same way as I am now in the first query and that works! I am confused :(</p> <p><strong>EDIT 2:</strong> the first query: <code>$result = mysqli_query($con,"SELECT * FROM suppliers WHERE LOWER(name) = LOWER('$searchText')");</code></p> <p><strong>EDIT 3:</strong> the result of doing <code>var_dump($resultContact);</code>: <code>object(mysqli_result)#3 (5) { ["current_field"]=&gt; int(0) ["field_count"]=&gt; int(4) ["lengths"]=&gt; NULL ["num_rows"]=&gt; int(0) ["type"]=&gt; int(0) }</code> I'm guessing this means that the query is coming back with the table ok, but the Where clause isn't comparing the contact name as I want it to...</p>

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.
