What is the error?

Member Avatar for Riu 2009

error it gives after pressing edit button is this

Notice: Undefined index: type in C:\xampp\htdocs\project\admin\users-edit-action.php on line 7

and this id the script on which it gives the error..i think error is due to wrong placement of values in radio buttons..

<?php include("../includes/config.php");?>
<?php
$id=$_POST["id"];
$firstname=$_POST["firstname"];
$lastname=$_POST["lastname"];
$email=$_POST["email"];
$type=$_POST["type"];

$con=mysql_connect($dbserver,$dbusername,$dbpassword);
if (!$con) { die('Could not connect: ' . mysql_error()); }


 mysql_select_db($dbname, $con);
$query=("UPDATE accounts SET firstname='".$firstname."' , lastname='".$lastname." email='".$email."' type='".$type."' WHERE (id='".$id."')");
$result = mysql_query($query);
echo "User has been updated Successfully!!";
mysql_close($con);
?>

I am wondering if your name="type" is causing a conflict as type is used as part of a form elements details. Have you tried changing it to something else and see what happens?

Also, are you sure that one of the radio buttons is being selected?

<input type="radio" name="type" value="<?php echo $type; ?>" /> Student<br />
<input type="radio" name="type" value="<?php echo $type; ?>" /> Teacher<br />

Why are you giving both radios the same value? It can't discrominate between them. I also suggest making one a default with checked="checked".

Member Avatar for Riu 2009

yup i know tht this is the wrong way but i cant understand how would i take the value from data base??? as i want to edit the already filled record then it should be checked already...how can i do that?? i mean how can i get the value of that type whether it is S or T..so that i could edit and change the type when i want to edit it..

Like diafol said (off topic:when did you change your username?) the radio button names need to be unique.

Ipso facto. <- that's latin BTW.

So, you radio buttons need to have unique names!

Now from your PHP file it is quite tedious to go through each name and check if it isset();

So we create a grouped radio button with the [] syntax in the HTML. That way we can just loop through using the foreach syntax.

@diafol well i want to retrieve the value from database.. how would i do that..the values are uniqe as thay are coming from database, i dont know how to check which value is selected in database to update it further..

Member Avatar for simplypixie

Like this:

<input type="radio" name="type" value="Student" <?php if ($type=='Student') { echo 'checked'; } ?> /> Student<br />
<input type="radio" name="type" value="Teacher" <?php if ($type=='Teacher') { echo 'checked'; } ?> /> Teacher<br />
