Why Does My PHP Code Throw a 'Call to a Member Function bind_param() on a Non-Object' Error?

Call to a Member Function bind_param() on a Non-Object [Duplicate]

When trying to bind a variable to a prepared SQL statement, the error "Call to a member function bind_param() on a non-object" indicates that the function prepare() has not been called successfully, resulting in a non-object reference when attempting to use bind_param().

One potential cause of prepare() failing is invalid SQL syntax. Ensuring that the table name and field names specified in the query are correct is crucial. The statement "SELECT * FROM users WHERE username = ?" must align with the table and field structure of your database. If any field does not exist, the statement will result in an error and cause prepare() to fail, leading to the bind_param() error.
