    <p>I want to display a record from a database in a table with checkboxes in every row. That checkboxes will determine if the user wants to delete that specific row if it will be checked. I was able to display the data from the DB but when i press the delete button nothing happen. Im not sure but i think the error is in my deleting part of the code but i could be wrong. Im not sure. Anyway, here is the code, i just remove some lines</p> <pre><code> &lt;?php $link = mysql_connect("localhost","root", "123"); if(!$link) { die('Failed to connect to server: ' . mysql_error()); } $db= mysql_select_db("abc"); if(!$db) { die("Unable to select database"); } $search = $_POST['search']; $searchbox = $_POST['searchbox']; $query = ("SELECT $search FROM table where $search = '$searchbox'"); $result=mysql_query($query); if($result) { if(mysql_num_rows($result)&lt;=0) { echo "&lt;script type='text/javascript'&gt;alert('The entry does not exist'); location.href = 'admin_home.php';&lt;/script&gt;"; } } switch ($search) { case 'studentnumber': $result = mysql_query("SELECT * FROM table WHERE $search = '$searchbox'"); if($result){ echo "&lt;table class='hovertable'&gt; &lt;tr&gt; &lt;caption&gt;Student Records&lt;/caption&gt; &lt;th colspan='1'&gt; Student Number&lt;/th&gt; &lt;th colspan='8'&gt; $searchbox&lt;/th&gt; &lt;/tr&gt; &lt;tr&gt; &lt;th&gt;Delete&lt;/th&gt; &lt;th&gt;Student Number&lt;/th&gt; &lt;th&gt;College&lt;/th&gt; &lt;th&gt;Course&lt;/th&gt; &lt;th&gt;Status&lt;/th&gt; &lt;th&gt;Last Name&lt;/th&gt; &lt;th&gt;First Name&lt;/th&gt; &lt;th&gt;Middle Name&lt;/th&gt; &lt;th&gt;Address&lt;/th&gt; &lt;th&gt;Gender&lt;/th&gt; &lt;th&gt;Civil Status&lt;/th&gt; &lt;th&gt;Religion&lt;/th&gt; &lt;th&gt;Email Address&lt;/th&gt; &lt;th&gt;Month&lt;/th&gt; &lt;th&gt;Day&lt;/th&gt; &lt;th&gt;Year&lt;/th&gt; &lt;th&gt;Father's Name&lt;/th&gt; &lt;th&gt;Father's Occupation&lt;/th&gt; &lt;th&gt;Mother's Name&lt;/th&gt; &lt;th&gt;Mother's Name&lt;/th&gt; &lt;/tr&gt;"; while($row = mysql_fetch_array($result)) { echo "&lt;tr onmouseover=\"this.style.backgroundColor='#ffff66';\" onmouseout=\"this.style.backgroundColor='#d4e3e5';\"&gt;"; ?&gt; &lt;td&gt;&lt;input name="need_delete[&lt;? echo $rows['id']; ?&gt;]" type="checkbox" id="checkbox[&lt;? echo $rows['id']; ?&gt;]" value="&lt;? echo $rows['id']; ?&gt;"&gt;&lt;/td&gt; &lt;?php echo "&lt;td&gt;" . $row['studentnumber'] .

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.
