HTML:
<input type="text" class="form-control" name="invoice" id="invoice" placeholder="piece">
<input type="text" class="form-control" name="pieces[]" id="pieces" placeholder="Qty">
I want to pass fields from ajax to php. I am using following code in ajax.
var inv = $("#invoice").val();
var pieces = $("#pieces").val();
$.ajax({
type: "POST",
url: "query.php",
data: "piece="+pieces+"&inv="+inv,
success: function(data){
$("#result").html(data);
}
});
following is the PHP code:
<?php
$piece = $_POST[piece];
foreach ($piece as $key => $value) {
$query = mysql_query(insert into items values('$value', '$_POST[inv]');
}
?>

Answer 1

Try this code
jQuery
var inv = $("#invoice").val();
var pieces = $("#pieces").val();
$.ajax({
type: "POST",
url: "query.php",
data: {'in':inv,'pi':pieces},
success: function(data){
$("#result").html(data);
}
});
php
<?php
$pieces = $_POST[piece];
foreach($pieces as $piece){
{
$query = mysql_query(insert into items values ('$piece','$_POST[inv]');
}
?>

Answer 2

Try this:
JQuery:
var inv = $("#invoice").val();
var pieces = $("#pieces").val();
$.ajax({
type: "POST",
url: "query.php",
data: {'in':inv,'pi':pieces},
success: function(data){
$("#result").html(data);
}
});
Php code :
<?php
$inv = $_POST['in'];
$piece = $_POST['pi'];
$query = mysql_query(insert into items values '$piece','$_POST[inv]');
?>
This is the simple example, please use mysql encapsulation to get value for preventing sql injection.
