    <p>I made this code:</p> <pre><code>&lt;?php if($this-&gt;session-&gt;userdata('login_user_id')); $a = $this-&gt;session-&gt;userdata('login_user_id'); $b = mysql_query("SELECT * FROM user WHERE id='$a' AND specialrank='1'") or die(mysql_error()); while($c = mysql_fetch_array( $b )) { Print $c['username']; } ?&gt; </code></pre> <p>basically it creates a session for the logged in user. I want to be able to show more in the print section though, some advanced php code and html form. Is there a way I can do this by reworking the code? It seems I'm limited with regards to which characters I can use within the print statement. Basically, I want to display a form to specific users and not others. I have tried closing the <code>&lt;?php ?&gt;</code> tags after every line to see if that works but it throws up errors of unexpected and expected's etc.</p> <p>EDIT:</p> <p>this is the segment of code I want to show:</p> <pre><code>&lt;?php // update if(isset($_POST['update'])) { $id = $_POST['id']; $emp_salary = $_POST['emp_salary']; $sql = "UPDATE pins SET is_private = $emp_salary WHERE id = $pinDetails-&gt;id"; mysql_select_db('test_db');$retval = mysql_query( $sql );if(! $retval ) { die('Could not change: ' . mysql_error()); } echo "Post is now private&lt;br&gt;&lt;br&gt;"; } ?&gt; &lt;form method="post" action="&lt;?php $_PHP_SELF ?&gt;"&gt; &lt;table width="400" border="0" cellspacing="1" cellpadding="2"&gt; &lt;tr&gt; &lt;td&gt;Private &lt;input name="emp_salary" type="text" id="emp_salary" value="1"&gt; &lt;input name="id" type="hidden" id="id"&gt; &lt;input name="update" type="submit" id="update" value="Change"&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/form&gt; </code></pre> <p>As you can see, simply putting that within the print throws up so many errors.</p>

    2. COCan you add in some of the code you've tried that isn't working? There's nothing wrong with what you're describing - you can certainly include an `if` statement in the loop along the lines of `if ($c['username'] == 'admin') {` to print out specific content - though bear in mind that if your query is just returning a single row, you don't need a `while` loop; a simple `if` should work.

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.
