What I want to do: Add a manager to my manager table.

function connect(){

$config =
    [
        'db' =>[
            'host' => 'localhost',
            'dbname' => 'crobi_solicitacao',
            'username' => 'root',
            'password' => '',
            'charset' => 'utf8'
        ]
    ];


$pdo = new \PDO("mysql:host={$config['db']['host']};dbname={$config['db']['dbname']};charset={$config['db']['charset']}",$config['db']['username'],$config['db']['password']);
$pdo->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);
$pdo->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE,PDO::FETCH_OBJ); //para trabalhar como objeto.
return $pdo;
}


function criar($table, $fields){

// para cadastrar no BD precisa estar na forma de array
if(!is_array($fields)){
    $fields = (array) $fields;
}
//PEGO A DATA PARA O MEU CAMPO 
$data_insert = date('Y-m-d');

$sql = "insert into {$table}" ."(" . implode(',',array_keys($fields)). ','."created_at" .")"." values(". ":".implode(',:',array_values($fields)).",:". "$data_insert" .")";

$pdo = connect();

$insert = $pdo->prepare($sql);

return $insert->execute($fields);
}

To find out how I got a dd ($ sql), I got the following result:

 string(114) "insert into gerente(name,email,area,created_at) values(:gerente,:[email protected],:t,:2018-05-10)"

What do I need to change to do the insertion?

I found the solution for those who need it:

 $sql = "insert into {$table}" ."(" . implode(',',array_keys($fields)) .")"." values(" . ":". implode(',:',array_keys($fields)) .")";

 $stmt = $pdo->prepare($sql);
    $stmt->bindParam(':name', $name);
    $stmt->bindParam(':name', $email);
    $stmt->bindParam(':name', $area);


$insert = $pdo->prepare($sql);

return $insert->execute($fields);

}

In both cases in the line below must be used array_keys :

$sql = "insert into {$table} (" . implode(',',array_keys($fields)). ','."created_at" .") values(:".implode(',:'.array_values($fields)).",:". "$data_insert" .")";

Replace array_values with array_keys .

You can see the error in the query print itself:

'values(:gerente,:[email protected],:t,:2018-05-10)'

These are the values and not tokens.

Another point is that you are adding created_at separately. It should add to the field as well and remove it from the $ sql string:

$fields['created_at'] = date('Y-m-d');
$sql = "insert into {$table} "."(" . implode(',',array_keys($fields)). ') values(:'.implode(',:',array_keys($fields)).")";
