    <p>I want to display icons for each tag, just like Stackoverflow does. <img src="https://i.stack.imgur.com/2jVIx.jpg" alt="Heroku"> <img src="https://i.stack.imgur.com/RwvIT.jpg" alt="Android"> <img src="https://i.stack.imgur.com/WVG2m.jpg" alt="Jetty"></p> <p>There are 2 tables related, table_icon and table_event.</p> <p>table_event is for recording the events happened, of course tags to each event; table_tag is for storing tags and icons to them.</p> <p>Here's the structure of table_icon:</p> <pre><code>tag_id tag_name icon (an url to an img) </code></pre> <p>Here's the structure of table_event:</p> <pre><code>event_id name modtime tag </code></pre> <p>In table_event, tag is stored "tag1,tag2,tag3" in tag cell.</p> <p>To make it clearer, Here's an example - </p> <p>Event: "Kobe Got Hurt", related tags: Kobe, Lakers, Injure</p> <p>table_event:</p> <pre><code>event_id ---- 1 name -------- Kobe Bryant got hurt modtime ----- Mar. 13, 2013 tag --------- Kobe,Lakers,injure </code></pre> <p>Corresponding table_tag: (say we have those data in table_tag before hand)</p> <pre><code>tag_id ------ 24 tag_name ---- Kobe icon -------- .../icon/kobe.png tag_id ------ 123 tag_name ---- Lakers icon -------- .../icon/NBA_team_lakers.png tag_id ------ 36 tag_name ---- injure icon -------- .../icon/red_cross.png </code></pre> <p>This is how I extract each tag in PHP:</p> <pre><code>... // Link to Db and table and call smarty. $t_sql = mysql_query("SELECT * FROM event WHERE 1"); $id = array(); $name = array(); $tag = array(); $icon = array(); while($t_row = mysql_fetch_array($t_sql)){ array_push($id, $t_row['event_id']); array_push($name, $t_row['name']); $tag_array = explode(',', $t_row['tag']); array_push($tag, $tag_array); // Don't know how to extract icon for each tag. } $smarty-&gt;assign('tid', $tid); $smarty-&gt;assign('name', $name); $smarty-&gt;assign('tag', $tag); $smarty-&gt;display('event.html'); </code></pre> <p>Any suggestion? Thx in advance!</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.
