How to dynamically pass input name to Jquery Single download page for each user

Without knowing how you are trying to record, I believe the logic you need is this:
HTML Exchange:

<input type="text" name="tamanho[]" id="tamanho" class="form-control porcelana" value="<?php echo $dados->preco; ?>"  />

by:

<input type="text" name="tamanho<?= $dados->id ?>" id="tamanho" class="form-control porcelana" value="<?= $dados->preco ?>"  />

submit = > "controller.php"

 $pdo = db_connect();
 $listar = $pdo->prepare("SELECT * FROM tamanhos");
 $listar->execute();
 while ($dados = $listar->fetch(PDO::FETCH_OBJ)){ 
   $dados->preco = $_REQUEST['tamanho'.$dados->id] ;

$sql = "update tamanho set preco = ? where id = ?";

    $statement = $pdo->prepare($sql);
    $statement->bindParam(1, $dados->preco);
    $statement->bindParam(2, $dados->id);

    $statement->execute();

}
