The reason is that this syntax is not supported:

$users = Users::find(array(
"conditions" => array("username" => "admin")
));

$users = Users::find(array( array('username' => 'admin' ) )); ??

I was doing the documentation as it should be?

That syntax is not supported, you must use:

$users = Users::find(array(
    "conditions" => "username = 'admin'"
));

$users = Users::find(array(
    "username = 'admin'"
));

$users = Users::find("username = 'admin'");

what a dick so it does not work? Why is it not transparent work with the database? I have worked with many ORM but your not be any damn explanation ...

$users = Users::query() ->where("username = :username:") ->andWhere("password = :password:") ->bind(array("username" => "'.$username.'", "password" => "'.$password.'")) ->limit(1) ->execute();

Wow man, are you ok? are you expecting get help talking that way to others?

Explanation of what? Can you point me to the docs/post/example where we say that syntax is supported?

What is this? ->bind(array("username" => "'.$username.'", "password" => "'.$password.'"))

Why are you adding quotes to bound parameters? Other ORM you have worked force you to double quote the data?

tell me how can substitute a variable?

$robots = Robots::query() ->where("type = :type:") ->andWhere("year < 2000") ->bind(array("type" => "mechanical")) ->order("name") ->execute();

This is the condition:

->where("type = :type:") 

It has a placeholder :type:, you pass a value for that using "bind":

->bind(array("type" => "mechanical")) // pass 'mechanical' to replace the :type: placeholder

->bind(array("type" => $type)) // pass a variable with any arbitrary value

->bind(array("type" => $this->request->getPost("type")) // pass a value from the request

$users = Users::query() ->where("username = :username:") ->andWhere("password = :password:") ->bind(array("username" => $username, "password" => $password)) ->limit(1) ->execute();

that is, the data is not replaced by

No, Phalcon does not replace the bound parameters, that task is perfomed by the MySQL server which knows the internal details of the active charset avoiding SQL injections.

$users = Users::query() ->where("username = :username:") ->andWhere("password = :password:") ->bind(array("username" => $username, "password" => $password)) ->limit(1) ->execute(); //$users -- Phalcon\Mvc\Model\Resultset\Simple $users = $users->toArray();

print_r $users 1 shows...

Users::query() will return a resulset of 1 or more records, in your case just use:

//Returns the first record that match the conditions
$user = Users::findFirst(array(
    "username = :username: AND password = :password:",
    "bind" => array("username" => $username, "password" => $password)
));

does not work

I'd rather use the built-in language

$users = Users::find( array( "conditions" => "username = ?1", "bind" => array(1 => $username) ) );

$users = $users->toArray();

Array ( [0] => Array ( [id] => 1 [role] => Administrator [firstname] => not filled [lastname] => not filled [email] => not filled [birthday] => not filled [sex] => not filled [username] => admin [password] => $2a$08$O1BmDY2XkgwjTB1UOEU4DemXMJKtN//TlK4CTvbpBh6 [logins] => 0 [last_login] => 0 ) )

$users = Users::find( array( "conditions" => "username = ?1 AND password = ?2", "bind" => array(1 => $username, 2 => $password) ) );

so I get just 1

my brain does not understand how it works for you here.

why is everyone so stupid to understand and difficult to
