Answer 1

Well. you may try this, it'll work if your result is not empty

public function export_to_csv($result)
{
    if(!$result) return false;
    ob_end_clean();
    header( 'Content-Type: text/csv' );
    header( 'Content-Disposition: attachment;filename=pedidos.csv');
    $fp = fopen('php://output', 'w');
    $headrow = $result[0];
    fputcsv($fp, array_keys($headrow));
    foreach ($result as $data) {
        fputcsv($fp, $data);
    }
    fclose($fp);
    $contLength = ob_get_length();
    header( 'Content-Length: '.$contLength);
}

Answer 2

Put this code below your loop.

header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="pedidos.csv"');

echo $shtml;

How did you find out the content type application/force-download? I've never heard of it. The proper MIME type for CSV is text/csv

You can find more examples how to use header function in php manual

You need also display $shtml you didn't do it in your code.

Answer 3

you need to echo your content after the header

header('Content-Description: File Transfer');
header('Content-Type: application/force-download');
header('Content-Disposition: attachment; filename=pedidos.csv');
echo $shtml
