Problem when displaying data in input

I'm having problems when it shows me the data well in the imput. I have two options one to add and one to edit, adding data is no problem, but when editing, in the imput I printate the data but not everything, that is, for example, if I have an input with several words for example the surnames, only the first surname appears to me, it does not appear to me if it has a space and then another word. The problem is that if I leave it like this when I click on the edit button, it is saved only with the first data and if that data has more text, it disappears. I do not know if I explain myself ... Is this the subject of the database?

if($_GET){

    $id= $_GET['id'];
    $sql_unico = 'SELECT * FROM reportes WHERE id=?';

$gsnet_unico = $pdo->prepare($sql_unico);
$gsnet_unico->execute(array($id));

$resultado_unico = $gsnet_unico->fetch();
}

<?php if($_GET):?>
    <h2>Editar elementos</h2>
