Why Am I Getting a 'Call to a member function bind_param() on a non-object' Error in My Prepared Statement?

Non-Object Call Error in bind_param() for Prepared Statements

When attempting to bind a variable in a prepared statement, it's common to encounter the error "Call to a member function bind_param() on a non-object." This issue occurs when the prepared statement is not initialized properly, resulting in a non-object being assigned to the variable.

To resolve this error, ensure that the prepare() method of the database connection ($DBH) is successful before attempting to bind parameters. The prepare() method validates the SQL statement and returns a prepared statement object on success, or false if the statement is invalid.

In the provided example, the error likely stems from incorrect SQL syntax. The error message suggests that the "username" field may not exist in the "users" table. Verify the validity of the SQL statement and ensure that all table and field names are correct.

Once the SQL statement is valid, check that the prepare() method returns an object. If it returns false, the statement is invalid and the binding operation will not succeed.
