Question

the following returns false and i don’t know how to find out what exactly is wrong.

$stmt = $dbo->stmt_init();
if($stmt->prepare("INSERT INTO transactions ('id', 'time') VALUES ('',?)")) // returns false
{
}

i have another statement which does an select open at that time. is it a problem to have more than one statements?

Answer 1

Have you verified that you are connecting to the database successfully?

/* check connection */
if ( mysqli_connect_errno() ) {
    printf("Connect failed: %s\n", mysqli_connect_error());
}

As far as figuring out what’s wrong with your prepared statement, you should be able to display $stmt->error, which will return a string description of the latest statement error, and $dbo->error, which will return the latest mysqli error.

printf("Error: %s.\n", $stmt->error);
