Hi

 

I am trying to create a page which will take session information and allow the user to update there record in the mysql database my friend gave me the following code but it wont work, anyone got any ideas whats wrong with it?

 

Many thanks

 

// Connect to server and select databse.
mysql_connect("$host", "$user", "$pass")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");

// ***** This part will process when you Click on "Submit" button ***** 
// Check, if you clicked "Submit" button 
if($_POST['Submit']){

// Get parameters from form. 
$username=$_POST['username'];
$forname=$_POST['forname'];
$password=$_POST['password'];


// Do update statement. 
mysql_query("update week9 set username='$username', forname='$forname', password='$password'");

// Close database connection. 
mysql_close();
}
?>

<!-- set this form to POST method and target this form to itself ($PHP_SELF;)--> 
<form id="form1" name="form1" method="post" action="<? echo $PHP_SELF; ?>">
<p>Username : 
<!-- name of this text field is "name" -->
<input name="name" type="text" id="username" value="<? echo $row['username']; ?>"/>

The first thing that stuck out to me was you're not specifying what record you want to update.

 

You have:

 

// Do update statement. 
mysql_query("update week9 set username='$username', forname='$forname', password='$password'");

 

Should be something like:

 

// Do update statement. 
mysql_query("UPDATE `week9` SET `username`= '$username', `forname` = '$forname', `password` = '$password' WHERE `id` = '$id' ");

 

Fix that first then post any errors.
