I have a problem with editing user information.
I want the password column to remain unchanged when no input is entered in the password field. Currently, when, for example, I only change the email, the password field is sent empty, and that empty field is saved as a hashed value in the password column.
Is there a way to solve this problem?
Case 1: If possible, I don't want the password change to be separate from the other information, and I want all of these to work correctly in one form tag.
Case 2: The password should not be changed by taking the current password because the admin does not have access to the user's password.
The codes are as follows:
