jquery request running more than once - php

Question

I have this code to make a request to a file that process some xls files ( with phpexcel library ) :
$("#applyCalls").click(function(){
$.get("admin/processCalls.php");
});
the processCalls.php looks like this:
include '../phpexcel2/Classes/PHPExcel.php';
include '../phpexcel2/Classes/PHPExcel/IOFactory.php';
date_default_timezone_set('Europe/Bucharest');
$fisierInbound = "inbound.xls";
$fisierOutbound = "outbound.xls";
callsInbound();
function callsInbound() {
global $fisierInbound;
global $current;
global $con;
$identify = PHPExcel_IOFactory::identify('daily/' . $fisierInbound);
$objReader = PHPExcel_IOFactory::createReader($identify);
$objReader->setReadDataOnly(true);
$objPHPExcel = $objReader->load('daily/' . $fisierInbound);
$worksheet = $objPHPExcel->setActiveSheetIndex(0);
$query = mysqli_query($con, "SELECT * FROM users WHERE tip_user='agent' AND NOT (departament='online')");
while($usr = mysqli_fetch_array($query)) {
$data[] = $usr;
}
$worksheetTitle = $worksheet->getTitle();
$highestRow = $worksheet->getHighestRow(); // e.g. 10
$highestColumn = $worksheet->getHighestColumn(); // e.g 'F'
$highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
$dataCalls = $worksheet->getCellByColumnAndRow(2, 2)->getValue();
$dataSubstr = substr($dataCalls, 53);
echo $dataSubstr;
foreach ($data as $db) {
for ($row = 6; $row <= $highestRow; ++ $row) {
$marca = $worksheet->getCellByColumnAndRow(3, $row)->getValue();
$nr = $worksheet->getCellByColumnAndRow(4, $row)->getValue();
if($db['marca'] == $marca) {
mysqli_query($con, "INSERT INTO dailycalls(data, nr, departament, oras, tip, id_user)
VALUES('$dataSubstr', '$nr', '" . $db['departament'] . "', '" . $db['oras'] . "', 'inbound', '" . $db['id'] . "')");
}
}
}
}
The thing is that I get "No data receive Error code: ERR_EMPTY_RESPONSE" (chrome) from processCalls, so the ajax request fails. As it fails I think it is running the file more than once, because I get more results than I need in the db. If I run the file manually I get the results I need. ( side note: the processCalls.php's query runs despite the error I get ). I hope that makes sense.
Thanks!

Answer 1

Check if the click function is getting binded more than once.
If the click function is binded more than once the function will be called multiple times.
$("#applyCalls").off('click', callServer).on('click', callServer);
var callServer = function(){
$.get("admin/processCalls.php");
};

Answer 2

Have you tried this?
$("#applyCalls").unbind("click").click(function(){$.get("admin/processCalls.php");});

Answer 3

Try to use stopPropagation() function.
Also as your PHP doesn't return anything you should use POST instead of GET
To understand the difference between POST and GET have a look at this article
$("#applyCalls").click(function(event){
event.stopPropagation()
$.post("admin/processCalls.php");
});
