Need advice to make php server side Datatables work properly

Question

There's something weird going on with server-side Datatables from this: https://github.com/n1crack/Datatables .

Don't understand what's going on, i do exactly the same thing as the examples but it simply doesn't work. According to the "where" example https://github.com/n1crack/Datatables/blob/master/public/examples/where/ajax.php , look how simple it should be:

$dt = new Datatables(new MySQL($config));
$dt->query("Select film_id as fid, title, description from film where film_id > 47 and film_id < 83");
echo $dt->generate();

My code:

$config = [ 'host'     => 'localhost',
        'port'     => '3306',
        'username' => 'root',
        'password' => '',
        'database' => 'sys_db_gincana' ];

        $dt = new Datatables( new MySQL($config) );
        $dt->query("
        SELECT seen, id, name, cep, date_format(created,'%d/%m/%Y %h:%i:%s') as created
        FROM user
        ");

        echo $dt->generate();

Now look at what my js console prints from my ajax:

And if if i change the query to:

        $dt = new Datatables( new MySQL($config) );
        $dt->query("
        SELECT seen, id, name, cep, date_format(created,'%d/%m/%Y %h:%i:%s') as created
        FROM user
        WHERE approved = 0 and canceled = 0
        ");
        echo $dt->generate();

the error changes:

A PHP Error was encountered

Severity: Warning

Message: array_merge(): Argument #2 is not an array

Filename: src/Datatables.php

Line Number: 47

: Call to a member function fetch_assoc() on a non-object in on line ：在的非对象上调用成员函数fetch_assoc（） 行

Well, the library is a bit new (january 2015), i wonder if someone that had success using it could help me. Regards

The problem in the WhereBuilder comes from the PHPSQLParser, can you test the latest version from https://github.com/greenlion/PHP-SQL-Parser ? It seems to be a simple SQL statement, so actually it should work. I have moved your issue to GitHub , please follow the changes there.
