You are not checking to see if the post data exists. Use isset to do that. Ex
if (isset($_POST['media_type'])) {
// Media type field was posted
}


Please do not create separate questions for the same underlying issue: Getting the value of a combo-box using post method

Update specific column in loop

Is this the right way to update a specific column for one row in mysqli_array_fetch? It doesn't work for me.

Your HTML formatting is strange but I think this should accomplish what you want.

Changes/potential improvements:
Using prepared statements in place of inline values.
Moved update outside of while loop since it is irrelevant.
Moved closing form tag inside the while loop. As is you were making multiple forms but every one was a child of the first because it never closed.
The p1s look like they might be headings? If so they should be outside of the loop.
If you want to display a message next to the row that was updated you could move the whole update process before the page process. Assign it to a variable the status to a variable then in the outputting when you are on that record output the message as well.
Your table rows seem to be closing incorrectly.

Php calculation is posting as 0

I am having a problem with getting the calculation to post anything but 0. all other post has the correct info from the form but the calculation is not working. all the data that comes from the inputs and the calculation of the total pallets works. It is just the total price.
The whole form:
if(!checkAdmin()) {
header("Location: login.php");
exit();
}
$page_limit = 10;
// filter GET values
foreach($_GET as $key => $value) {
$get[$key] = filter($value);
}
foreach($_POST as $key => $value) {
$post[$key] = filter($value);
}

It appears you are using $_post (lower case) instead of $_POST (uppercase) for your pallets vars.
Try outputting a print_r($_POST) to see what you are getting in your $_POST array. It could just be you are referencing the wrong vars.

</html>
I need to do a lot of modifications by converting " to ' and ' to " at many places inside the html tags to get the syntax correct for the echo statement... Is there any better way for doing this ??

You should close the PHP tag once a condition is written. First separate the DB logic and other stuff in another file, or at the top of the document:
<?php
$num=1;
mysql_connect("localhost","root","");
mysql_select_db("attendance");
$_SESSION['tablename']=$_GET['dept']."-".$_GET['year']."-".$_GET['sec']."-".$_GET['sem'];
//echo $_SESSION['tablename'];
$_SESSION['subject']=$_GET['subject'];
$_SESSION['datepicker']=$_GET['datepicker'];
$qstr2="select * from `".$_SESSION['tablename']."-total` where date='".$_GET['datepicker']."' and subject='".$_GET['subject']."';";
//echo $qstr2;
$check=mysql_query($qstr2);
$qstr="select * from `".$_SESSION['tablename']."`;";
$result=mysql_query($qstr);
?>
Then start with conditions:
<?php if($check): ?>
<font color='white' align=center face='Lucida Sans Unicode'><h2 class='centered'>Attendence for the selected date was already entered</h2></font><br><br><br><br>
<?php else: ?>
<?php if(!$result): ?>
<p>Invalid details selected</p>
<?php else: ?>
<font color="white" align=center face="Lucida Sans Unicode"><h2>Enter Attendance</h2></font>
<form method="post" action="insertatt.php" ><p align="center">
<table id="box-table-a"; >
<thead>
<tr>
<th scope="col"> Sl.No </th>
<th scope="col"> JNTU No. </th>
<th scope="col"> Name </th>
<th scope="col"> Classes </th>
</tr>
</thead>
<tbody>
<?php $num=1;while($row=mysql_fetch_array($result)): ?>
<tr><td><?= $row['Sl.No']; ?></td>
<td><?= $row['Name']; ?></td>
<td><input type='radio' name='rbtn<?=$num;?>' value=1 /> 1
<input type='radio' name='rbtn<?=$num;?>' value=2 /> 2</td>
</tr>
<?php $num=$num+1; ?>
<?php endwhile: ?>
</tbody>
</table>
<input type='submit' name='submit' value='Post Attendance' />
<input type='reset' name='reset' value='Clear Form' /></p><br><br>
</form>
<?php endif; ?>
<?php endif; ?>
</div>
<footer><div id="footer">© 2013 Team 17</div>
</footer>
This way the php's echo won't disturb your quotation, so you can standartize the quotes to be only double or only single (I didn't change yours)

Fwrite not writing inside of if statement

I have a fwrite writing each business' page but i want it so that it only shows the html of the page when you go to the url with a valid session so i wrote
fwrite($fp,"
However when it writes the page it writes this . The isset statement is gone from the if statement.
<?php
$recid = $_POST['recid'];
$username = $_POST['name'];
$email = $_POST['email'];
$ownername = $_POST['ownername'];
include ("connection.php");
$result = $db->query("UPDATE users SET verified='y' WHERE recid='$recid'");

The reason is because you are using the following line:
fwrite($fp, "if(isset({$_SESSION['id']})) { ?");
Because you are using double quotes it means that the session value {$_SESSION['id']} will be parsed by PHP, before being written to the file via fwrite. If you change your quotes to single quotes you wont have this problem, as PHP will leave single quoted strings alone — i.e. not parse them for variables:
fwrite($fp, 'if(isset($_SESSION["id"])) { ?');
You should also remove the surrounding curly braces on the session var, unless you want your php to be erroneous when it is reparsed.
This is all assuming that the outcome you want in the file is:
if(isset($_SESSION["id"])) { ?

Getting the value of a combo-box using post method

I wanted to use php to get the value of a combo box, and I am using post method...
can anyone tell me how.

?>

</body>
</html>
this is the combo box.

Try:
if(isset($_POST['media_type']){
$value = $_POST['media_type'];
}
Update: Since that doesn't work for you, check to see if you are getting any post variables:
foreach ($_POST as $var => $value) {
echo "$var = $value<br>n";
}
