how to pass a Javascript array from Javascript to PHP through Jquery/Ajax?
Question
I would like to know how I can pass a Javascript array from Javascript to PHP through Jquery/Ajax . In fact I created two files: t1.html and moslem3.php . The code of each file is below:
The code of t1.html:
<html>
<head>
</head>
<body>
<script type="text/javascript">
$(document).ready(function() {
var table = ["actor", "subject", "object"];
$.ajax({
type: "POST",
url: 'moslem3.php',
data: table
});
});
</script>
</body>
</html>
The code of moslem3.php:
<?php
$myArray = $_REQUEST['table'];
echo $myArray;
?>
The file moslem3.php displays this message:
Notice: Undefined index: table in C:\wamp\www\test1\moslem3.php on line 2
So my question is: where is the wrong here exactly?..Is there any one who has any idea?
Thanks in advance.

PHP doesn't inherently know anything about the JavaScript variables being used, such as var table . Its insights for the $.ajax() request are completed limited to the data structure.
So, for PHP to know about a 'table' parameter in $_REQUEST , the data needs to include it that as a named value:
data: { table: table }
This defines the data as an Object with a property table assigned to the value of the variable by the same name.
You can witness the difference using $.param() , which $.ajax() uses:
var table = ["actor", "subject", "object"];
console.log($.param(table));
// "undefined=&undefined=&undefined="
console.log($.param({ table: table }));
// "table%5B%5D=actor&table%5B%5D=subject&table%5B%5D=object"

Change Jquery
<script type="text/javascript">
$(document).ready(function() {
var table = ["actor", "subject", "object"];
$.ajax({
type: "POST",
url: 'moslem3.php',
data: {t_name:table },
success:function(data){
console.log(data);
}
});
});
</script>
Change in moslem3.php
<?php
$myArray = $_REQUEST['t_name'];
print_r($myArray);
?>
Output:

Try this :
$.ajax({
type : "POST",
url: 'moslem3.php',
cache:false,
async:true,
global:false,
data : {
"table": table }
}).done(function(msg) {
alert(msg);
})
