Jak jsi tam psal, ty zadas pozadavek a db ti vrati vysledky ala json, treba. Tak ti to muze vracet jako csv, ten samy php kod. Tak jsem to myslel. Prijde mi to jednodussi nez se drbat s javascriptem, kdyz uz mas vlastne vse hotove.
Pokud to ale nasledne jeste nejak filtrujes u uzivatele, i tak by bylo jednodussi poslat ty filtry php. Hlavne jde o to, ze php ma na csv funkce.
$filters = $_POST['filters']; // samozrejme bys pridal kontroly proti hackingu a tak
$q = "SELECT ... WHERE ".$filters;
$data = ... fetch();
// https://stackoverflow.com/…array-to-csv
function array2csv($data, $delimiter = ',', $enclosure = '"', $escape_char = "\\")
{
$f = fopen('php://memory', 'r+');
foreach ($data as $item) {
fputcsv($f, $item, $delimiter, $enclosure, $escape_char);
}
rewind($f);
return stream_get_contents($f);
}
$list = array (
array('aaa', 'bbb', 'ccc', 'dddd'),
array('123', '456', '789'),
array('"aaa"', '"bbb"')
);
var_dump(array2csv($list));
// ---NEBO---
$f=fopen('php://memory','w');
$header=array("asdf ","asdf","asd","Calasdflee","Start Time","End Time" );
fputcsv($f,$header);
fputcsv($f,$header);
fputcsv($f,$header);
fseek($f,0);
header('content-type:text/csv');
header('Content-Disposition: attachment; filename="' . $filename . '";');
fpassthru($f);```
Tuhle jsem delal pro nejaky program, export csv, json, xml, html table, php array().
