    <p>I'm having a strange issue with putting a query into a html table to be displayed in a php/mysql set up. The query will always produce one more result than is shown. For example, if 1 set of results was returned, nothing would show in the table. If there are 5, only 4 get shown. I've tried the same queries with a pre-defined function to produce a table based on a query and it produced the right table with the correct number of results. Here is an example (apologies for the indenting, or lack thereof):</p> <pre><code>$user_id = implode($_SESSION['user_id']); $query = "SELECT name, address FROM user WHERE user_id = '$user_id' ORDER BY date_added DESC"; $result = mysql_query($query) or die ("query failed: " . mysql_error()); echo "&lt;table border='1' style=\"border-collapse: collapse;\"&gt; &lt;tr style=\"background-color: #000066; color: #FFFFFF;\"&gt; &lt;th&gt;Name&lt;/th&gt; &lt;th&gt;Address&lt;/th&gt; &lt;/tr&gt;"; $rowCt = 0; // Row counter while($row = mysql_fetch_array($result)) { if($rowCt++ % 2 == 0) $Style = "background-color: #00CCCC;"; else $Style = "background-color: #0099CC;"; echo "&lt;tr style=\"$Style\"&gt;"; echo "&lt;td&gt;" . $row['name'] . "&lt;/td&gt;"; echo "&lt;td&gt;" . $row['address'] . "&lt;/td&gt;"; echo "&lt;/tr&gt;"; } echo "&lt;/table&gt;"; </code></pre> <p>Any idea why this is happening? Any help would be greatly appreciated, it's been driving me crazy and need to figure it out before I can move on! Thanks.</p> <p><em>EDIT</em></p> <p>I've altered it slightly to loop through the amount of rows as that number is correct, and the table is now the correct size, however the last result is always empty. Any ideas?</p> <pre><code>$rowCt = 0; // Row counter $i = 0; echo mysql_num_rows($result). ' number of rows'; $num = mysql_num_rows($result); //while($row = mysql_fetch_array($result)) while ($i &lt; $num) { $row = mysql_fetch_array($result); if($rowCt++ % 2 == 0) $Style = "background-color: #00CCCC;"; else $Style = "background-color: #0099CC;"; echo "&lt;tr style=\"$Style\"&gt;"; echo "&lt;td&gt;" . $row['name'] . "&lt;/td&gt;"; echo "&lt;td&gt;" . $row['address'] . "&lt;/td&gt;"; echo "&lt;/tr&gt;"; $i++; } echo "&lt;/table&gt;"; </code></pre> <p>Thanks</p>

    1. COecho mysql_num_rows($result); and make sure it returns the number of rows you expect

    3. COI see nothing wrong with your code. Only in you while, you have an if and else, try commenting them out and look what happens, it could do something unexpected. Also i suggest to execute the $query directly in phpmyadmin (if installed) and see the returned dataset to confirm the returned data.

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.
