How to update MySql data from HTML using PHP? - php

Question

I am trying to update mysql database from html table with php, but when edit the row that i want to update and press the button to update, field that was suposed to updated becomes empty.
Also when i press update i get this notice:
Notice: Undefined index: status in /storage/ssd1/314/2412314/public_html/status3.php on line 174.
This is my code:
<?php
$db_host='example';
$db_user='example';
$db_pass='example';
$db_name='example';
$con = mysqli_connect($db_host, $db_user, $db_pass, $db_name);
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
if(isset($_POST['update']))
{
$STATUS = $_POST['status'];
$PK= $_POST['pkvara'];
$sql = "UPDATE Radionica SET status = '$STATUS' WHERE pkvara = '$PK'";
$retval = mysqli_query($con,$sql );
if(! $retval )
{
die('Could not update data: ' . mysql_error());
}
echo "Status uspešno promenjen\n";
}
$result = mysqli_query($con,"SELECT * FROM Radionica")
or die("Error: ".mysqli_error($con));
while($row = mysqli_fetch_array($result))
{
echo '<form action="" method="post">';
echo '<tr>';
echo '<td>'.$row['registracija'].'</td>';
echo '<td>'.$row['status'].'</td>';
echo '<td><input type="text" name="sta" value="'.$row['status'].'"><input type="submit" name="update" value="Promeni" /></td>';
echo'<td><input type="hidden" name="pkvara" value="'.$row['pkvara'].'"></td>';
echo '</tr>';
echo '</form>';
}
mysqli_close($con);
?>
