php - Write to file and send AJAX response at once -

update:

i used solution write data file. seems can't echo data while ajax waiting response. use fwrite.

$filehandle = ''; $filehandle = fopen("export.txt","w"); fwrite($filehandle, $export); 

---

original:

hi there, maybe logic wrong. make ajax call data url. worked far.

but want add file export also.

$handler = new myhandler(); // step 1: data url $dataajax = $handler->getdata($_post['data']); // step 2: write data text file provide download $handler->writetotext($dataajax); echo json_encode($dataajax); 

now console shows me "parsererror" because json data contains string wanted write file. that's bad , unwanted. below test how want write data txt file:

function writetotext($data) {    header("content-type: text/plain");    header("content-disposition: attachment; filename=export.txt");    header("pragma: no-cache");    header("expires: 0");    $title = "";    $title .= "name,quantity,model,price,weight,status"."\n";    echo $title; } 

that how error looks like:

{     "readystate": 4,     "responsetext": "name,quantity,model,price,weight,status\n[{\"domain\":\"text\",\"name\":\"banana\}]",     "status": 200,     "statustext": "ok" }   parsererror
