PHP update script

Having trouble with this upload script, it grabs and displays the content from the database fine. It won't however update the database although the code is throwing up no errors;
this is the script that displays the content

PHP Code:


			
############### Code



<?php

include("includes/connection.php");



$sql="SELECT * FROM mot";

$result=mysql_query($sql);

?>

<table width="400" border="0" cellspacing="1" cellpadding="0">

<tr>

<td>

<table width="400" border="1" cellspacing="0" cellpadding="3">

<tr>

<td colspan="4"><strong>List data from mysql </strong> </td>

</tr>



<tr>

<td align="center"><strong>Name</strong></td>

<td align="center"><strong>Lastname</strong></td>

<td align="center"><strong>Update</strong></td>

</tr>

<?php

while($rows=mysql_fetch_array($result)){

?>

<tr>

<td><? echo $rows['header']; ?></td>

<td><? echo $rows['content']; ?></td>



// link to update.php and send value of id 

<td align="center"><a href="update_content.php?id=<? echo $rows['id']; ?>">update</a></td>

</tr>

<?php

}

?>

</table>

</td>

</tr>

</table>

<?php

mysql_close();

?>

this next bit of code is the code that user updates the content;

PHP Code:


			
<?php 



include("includes/connection.php");



// get value of id that sent from address bar

$id=$_GET['id'];





// Retrieve data from database 

$sql="SELECT * FROM mot WHERE id='$id'";

$result=mysql_query($sql);



$rows=mysql_fetch_array($result);

?>

<table width="400" border="0" cellspacing="1" cellpadding="0">

<tr>

<form name="form1" method="post" action="update_ac.php">

<td>

<table width="100%" border="0" cellspacing="1" cellpadding="0">

<tr>

<td>&nbsp;</td>

<td colspan="3"><strong>Update data in mysql</strong> </td>

</tr>

<tr>

<td align="center">&nbsp;</td>

<td align="center">&nbsp;</td>

<td align="center">&nbsp;</td>

<td align="center">&nbsp;</td>

</tr>

<tr>

<td align="center">&nbsp;</td>

<td align="center"><strong>Name</strong></td>

<td align="center"><strong>Lastname</strong></td>

</tr>

<tr>

<td>&nbsp;</td>

<td align="center"><input name="name" type="text" id="name" value="<? echo $rows['header']; ?>"></td>

<td align="center"><input name="lastname" type="text" id="lastname" value="<? echo $rows['content']; ?>" size="15"></td>

</tr>

<tr>

<td>&nbsp;</td>

<td><input name="id" type="hidden" id="id" value="<? echo $rows['id']; ?>"></td>

<td align="center"><input type="submit" name="Submit" value="Submit"></td>

<td>&nbsp;</td>

</tr>

</table>

</td>

</form>

</tr>

</table>



<?



// close connection 

mysql_close();



?>

this final bit is the update code for the database which isnt working but not throwing up any errors

PHP Code:


			
<?php

 

include("includes/connection.php");



// If form button has been pressed then do the following 

if(isset($_POST['update'])){ 

// Get id of post 

$id = $_GET['id'];



$header = $_POST['header'];

$content = $_POST['content'];

 

// update data in mysql database 

$sql="UPDATE mot SET header = '$header', content = '$content' WHERE id='$id'";

$result=mysql_query($sql);



// if successfully updated. 

if($result){

echo "Successful";

echo "<BR>";

echo "<a href='mot_edit.php'> View result</a>";

}



else {

echo "ERROR";

}

}

?>

Any help would be much appreciated
