Not sure what I'm missing here.  I a very similar script updating fields with no problems.   The data is being called from the database without any errors, but as soon as I hit submit whether or not I update a field or not I get a couple of undefined variables.  Did I misplace a curly bracket?

 

thanks,

I get a couple of undefined variables.

 

 

care to share what those errors were so that we don't have to guess?

 

we don't have the ability to run your code with your data, so you must share what you know about a problem in order to help those that would take the time to try and help you with your code problems.

As mac_gyver mentioned, it would be helpful to know the errors.

 

One thing that I noticed is that your select box is named "discipline"

<select name="discipline">

And the code that processes the form submission uses "user_discipline" as the index for $_POST

$user_discipline =mysqli_real_escape_string($conn,$_POST['user_discipline']);

Besides what other posters said...

 

Initially you get the id from a $_GET['id']

That's fine but when you post the form is not being passed because now using POST and not included in the action, the query does not know where to update to a specific id.

 

Pass the id into the update form a hidden type.

<input type="hidden" name="id" value="<?php echo $id;?>"/>

 

 

Now add the $id back in the update submit check

if(isset($_POST['update'])){

 

if(isset($_POST['id']) && is_numeric($_POST['id'])){
        
        $id=$_POST['id'];
        
}

 

//.....rest of code

 

 

You may as well change the GET id one to $id , when query runs you return the $row['id'] anyway

 

if(isset($_GET['id']) && is_numeric($_GET['id'])){
            
        $id=$_GET['id'];
        
        $sql = "select * from hsa_users where id='$id'";

Looking over the code....

 

If $_GET['id'] is not set, then none of the variables are going to be defined.

$row is defined twice and only the second definition counts.

Put in some echo's to see what is going on along the code path.

        $row=mysqli_fetch_assoc($result);    
            
        $run = mysqli_query($conn,$sql);    
            
        $row=mysqli_fetch_array($run);

Also....

 

Place this section before your form, are trying to use all variables that do not exist yet.

}
            
            $user_firstName        =mysqli_real_escape_string($conn,$_POST['user_firstName']);
            $user_lastName        =mysqli_real_escape_string($conn,$_POST['user_lastName']);
            $user_company        =mysqli_real_escape_string($conn,$_POST['user_company']);

with your 60 posts and 2+ months on this forum, you should be at the point, after just a couple (2) or a few (3-4) weeks, of being able to find and fix simple things like undefined variables and undefined indexes in posted form data.

(if you were editing an existing record, you would retrieve that data here...)

This should be better with the changes.

 

Should have a bit more error checking in this though.

session_start();

$conn = mysqli_connect("localhost", "root", "", "hsa_project_hub");


if (!$_SESSION['admin_login']) {
    header("location: admin_login.php");
    exit;
}

$id = '';

// Grab user id from admin_userList.php and pull user info from database    
if (isset($_GET['id']) && is_numeric($_GET['id'])) {
    
    $id = $_GET['id'];
    
    $sql = "select * from hsa_users where id='$id'";
    
    $result = mysqli_query($conn, $sql);
    $row    = mysqli_fetch_assoc($result);
    
    $run = mysqli_query($conn, $sql);
    
    $row             = mysqli_fetch_array($run);

  Yes mac_gyver i did try to find out why I was getting errors.  I have not been at my computer for awhile because I had a family member pass away and I just did not have recall did when I was trying to code every day after work.  I before I took a break I created a nice file management system that associates files with each rfi or submittal in the user has the need.   I just need to get back into things.  I feel like I forgot a lot.
