Why is My Login Form Failing to Connect to MySQL and How Can I Fix It Using mysqli_fetch_array()?

Can't Connect Login Form to MySQL Database

This inquiry pertains to a login form that is failing to establish a connection with a MySQL database. The user has specified a database schema, and the login and registration processes are shown, utilizing password hashing and verification to ensure data security.

The Source of the Issue

The main problem lies in the improper use of mysqli_fetch_assoc(). This function is not suitable for retrieving a single row of data, as it assumes multiple rows are present. Instead, the proper method is to use mysqli_fetch_array(), which retrieves a single row as an associative array.

The Corrected Code

To resolve the issue, replace the problematic line:

if ($row = $result->fetch_assoc()) {

with the correct code:

if ($row = $result->fetch_array()) {

This modification ensures that the row data is fetched correctly, enabling the login process to verify the password and proceed accordingly.
