    <p>I am making a user management system what i want to do is when the user is logged in he cant see (ex. sales employee) he cant see links for other departments, what I'm trying to do is simple but I don't know why its not working, my code is: </p> <pre><code>$departmentidquery = mysql_query("SELECT department_id FROM users WHERE username = '".$username."'"); $departmnetid = mysql_fetch_row ($departmentidquery); &lt;ul&gt; &lt;li&gt;&lt;a href="logout.php"&gt;Logout.&lt;/a&gt;&lt;/li&gt; &lt;li &lt;?php if ($departmnetid[0]!=1){?&gt;style="display:none"&lt;?php } ?&gt;&gt; &lt;a href="admin.php"&gt;Admin Pgae&lt;/a&gt; &lt;/li&gt; &lt;li &lt;?php if ($departmnetid[0]!=2){?&gt;style="display:none"&lt;?php } ?&gt;&gt; &lt;a href="sales.php"&gt;sales Pgae&lt;/a&gt; &lt;/li&gt; &lt;li &lt;?php if ($departmnetid[0]!=3){?&gt;style="display:none"&lt;?php } ?&gt;&gt; &lt;a href="tech.php"&gt;Tech Pgae&lt;/a&gt; &lt;/li&gt; &lt;/ul&gt; </code></pre> <p>The error is:</p> <pre><code>SCREAM: Error suppression ignored for ( ! ) Notice: Undefined variable: departmnetid in C:\wamp\www\Ticket.sys\index.php on line 49 SCREAM: Error suppression ignored for ( ! ) Notice: Undefined variable: departmnetid in C:\wamp\www\Ticket.sys\index.php on line 50 SCREAM: Error suppression ignored for ( ! ) Notice: Undefined variable: departmnetid in C:\wamp\www\Ticket.sys\index.php on line 51 </code></pre> <p>I am sure from the query, I already tried the trick of <code>display:none</code> with <code>&lt;div&gt;</code> and its working, is there a better way to do that? </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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
