I have a a page where users create and account and edit password if the account already exists. I'm using php - codeigniter 

When users update passwords, the input field currently allows them to change their username as well as their password. I'm trying to make it so that users can only update passwords and not usernames but I have had trouble doing so.

**This is my code**

```
<input required type="text" 
placeholder="page name" 
value="<?= $form_value['name'] ?>" name="name" id="name">

```

I am trying to make it so that the username is printed but it is not updated.

The only thing I can think of is making the input type hidden (as shown in the below code), but then users can minipulate it and change it in the inspect element option of the browser and update their users.

```
<input required type="hidden" placeholder="page name" value="<?= $form_value['name'] ?>" name="name" id="name">

```

I am not sure what to do,
Thanks in advance
