    <p>I am making a social networking site where I want to have a user's pals shown in a PHP generated table. I want to show pal thumbnails and other information below these thumbnails so that if you click on a thumbnail, it takes you to that user's profile. </p> <p>My code:</p> <pre><code>&lt;?php //code for displaying all your pals $query_pal_array = "SELECT pal_array FROM users WHERE user_id='$user_id'"; $pal_array_result = mysql_query($query_pal_array, $connections) or die(mysql_error()); $row_pal_array = mysql_fetch_assoc($pal_array_result); $pal_array = $row_pal_array['pal_array']; $palList = ""; if($pal_array !="") { $palArray = explode(",",$pal_array); $palCount = count($palArray); } else { $palCount = "0"; } //get pal avatars $query_pal_info = "SELECT users.user_id, user_first_name, user_last_name, username, picture_thumb_url, avatar FROM users LEFT JOIN picture ON users.user_id = picture.user_id AND picture.avatar=1 WHERE users.user_id IN ($pal_array)"; $pal_info = mysql_query($query_pal_info , $connections) or die(mysql_error()); $totalRows_pal_info = mysql_num_rows($pal_info ); echo $pal_array; echo "\n&lt;table&gt;"; $j = 5; while ($row_pal_info = mysql_fetch_assoc($pal_info)) { if($j==5) echo "\n\t&lt;tr&gt;"; $thumbnail_user = $row_pal_info['picture_thumb_url'] != '' ? $row_pal_info['picture_thumb_url'] : '../Style/Images/default_avatar.png'; echo "&lt;td width='100' height='100' align='center' valign='middle'&gt;&lt;a href = 'user_view.php?user_id2=$pal_array'&gt; &lt;img src='/NNL/User_Images/$thumbnail_user' border='0'/&gt;&lt;/a&gt;&lt;/td&gt;\n"; $j--; if($j==0) { echo "\n\t&lt;/tr&gt;\n\t&lt;tr&gt;"; $j = 5; } } if($j!=5) echo "\n\t\t&lt;td colspan=\"$j\"&gt;&lt;/td&gt;\n\t&lt;/tr&gt;"; echo "\n&lt;/table&gt;"; ?&gt; &lt;table width="500" border="0"&gt; &lt;tr&gt; &lt;td height="20"&gt;&lt;div class="heading_text_18"&gt;&lt;?php echo $row_user_info ['username']; ?&gt;'s&amp;nbsp;pals &lt;?php echo $palCount ?&gt;&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td class="interactionLinksDiv" align="right" style="border:none;"&gt;&lt;a href="#" onclick="return false" onmousedown="javascript: toggleInteractContainers('pal_requests');"&gt;Pal Requests&lt;/a&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td height="5"&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </code></pre> <p>I have user_id values stored in an array $pal_array. These are pal user_id numbers. When the thumbnails show, they all link to the last user_id in the array. What am I doing wrong. Im just learning PHP.</p>

    2. COok, whats the way to fix it? When I echo $pal_array, I get 94,92 ie, user_id 94 and 92. The 2 thumbnails both link to user 94's profile.

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.
