Update sql data from form and checkboxes - php

Question

I have created a form that update the data in a sql column, so far all good.
The problem I have is that I would like to choose what columns are going to be updated, with checkboxes.
So I want to categorize two files as movies, I just check the checkbox and write movies in the form.
But its not only that. Every column is already connected to a checkbox, but I use this checkbox with an delete query, so I can delete multiple rows.
So my question is more like, how can I combine this two function with "one" checkbox.
This is some of my code.
This is my table with the sql outputs, and with the delete button
<?php
$files = mysql_query("SELECT * FROM files WHERE `user_name` = '{$_SESSION['username']}' ORDER BY `file_time` DESC LIMIT $start, $per_page")
or die(mysql_error());
?>
<table id="table-3">
<thead>
<tr>
<th scope="col">Upload User</th>
<th scope="col">Filename</th>
<th scope="col">Upload date</th>
<th scope="col">IP adress</th>
<th scope="col">Category</th>
<th scope="col">Delete</th>
</tr>
</thead>
<?php
while (($row = mysql_fetch_assoc( $files )) !==false)
{
echo "<tr>";
echo "<td>".$row['user_name'] . "</td> ";
?>
<td class="download"> <?php echo $row['file_name']; ?></td>
<?php echo "<td>".$row['file_time'] . "</td> "; ?>
<?php echo "<td>".$row['file_ip'] . "</td> "; ?>
<?php echo "<td>".$row['category'] . "</td> "; ?>
<td>
<form action="delete.php" method="post">
<input type="checkbox" name="done[]" id="<?php echo $row['file_id'] ?>" value="<?php echo $row['file_id'] ?>">
</td>
<?php
}
echo "</tr>";
echo "</table>";
?>
<input type ="submit" value ="Delete">
</form>
This form is the one with the update function
<form action="function.php" method="post">
category: <input type="text" name="category" />
<input type="submit" />
</form>
and
function.php
include('core/inc/init.inc.php');
if(isset($_POST['category'])){
$category = $_POST['category'];
mysql_query("UPDATE files SET category='$category'
/*WHERE category='genom' */ ");
header("Location: profile.php?uid=" . $_SESSION['uid']);
}else{
header("Location: profile.php?uid=" . $_SESSION['uid']);
};
How can I combine these two functions?

You can have multiple submit buttons in the same form. So you can do something like this:
<?php
$files = mysql_query("SELECT * FROM files WHERE `user_name` = '{$_SESSION['username']}' ORDER BY `file_time` DESC LIMIT $start, $per_page")
or die(mysql_error());
?>
<form action="updateordelete.php" method="post">
<table id="table-3">
<thead>
<tr>
<th scope="col">Upload User</th>
<th scope="col">Filename</th>
<th scope="col">Upload date</th>
<th scope="col">IP adress</th>
<th scope="col">Category</th>
<th scope="col">Delete</th>
</tr>
</thead>
<?php
while (($row = mysql_fetch_assoc( $files )) !==false)
{
?>
<tr>
<td> <?php echo $row['user_name']; ?></td>
<td class="download"> <?php echo $row['file_name']; ?></td>
<td><input type="text" name="file_time[<?php echo $row ['file_id']; ?>]" value="<?php echo $row['file_time']; ?>" /></td>
<td><input type="text" name="file_ip[<?php echo $row ['file_id']; ?>]" value="<?php echo $row['file_ip']; ?>" /></td>
<td><input type="text" name="file_category[<?php echo $row ['file_id']; ?>]" value="<?php echo $row['category']; ?>" /></td>
<td><input type="checkbox" name="done[]" id="<?php echo $row['file_id'] ?>" value="<?php echo $row['file_id'] ?>"></td>
</tr>
<?php } ?>
</table>
<input type ="submit" name="submittype" value = "Update">
<input type ="submit" name="submittype" value = "Delete">
</form>
And then, in updateordelete.php:
if($_POST['submittype']=="Delete"){
(do delete code...)
}elseif($_POST['submittype']=="Update"){
(do update code...)
}
For each of the values, you can access them using $_POST['file_category']. For example:
$file_categories=$_POST['file_category'];
foreach($_POST['done'] as $file_id){
echo $file_categories[$file_id];
}
