Question

dd = [ [2,3], [4], [2], [1,2,3] ]

for i in dd:

if len(i)==1:
    dd.remove(i)
    print(dd)
else:
    pass

print(dd)

`$order = $_POST['column_name']` this is what you should have on your server or change `data: { column_name: "sortOrder"},` to `data: { sortOrder: sortOrder},` — Masivuye Cokile, Oct 02 '19 at 12:19
@MasivuyeCokile then i get Notice: Undefined index: column_name in /opt/lampp/htdocs/final/sort.php on line 4 error — Vaibhav Kakade, Oct 02 '19 at 12:22
@Vk check what formdata is being sent from your developer console network tab — Masivuye Cokile, Oct 02 '19 at 12:23
@MasivuyeCokile I get "GET localhost sort.php?column_name=ASC" which seems correct — Vaibhav Kakade, Oct 02 '19 at 12:35
@Vk This is a GET request, not POST. Which method do you really use? — Dharman, Oct 02 '19 at 12:36

Your AJAX call is incorrect.

You are passing an object which has a property called column_name which contains a literal string "sortOrder".

Try something like this:

function sortby(selectObject) {
    var sortOrder = selectObject.value;
    $.ajax({
        url: "sort.php",
        method: "POST",
        data: { column_name: sortOrder },
        success: function(data) {
            $('#allProducts').html(data);
        }
    })
    console.log("called");
}

And then in PHP:

<?php
if(isset($_POST['column_name']) {
    // do something here
} else {
    echo 'No value was passed!';
}

I get No value was passed – Vaibhav Kakade Oct 02 '19 at 12:33
Did you check your network tab in your browser, to see what values are sent? Did you check in PHP the contents of POST array? – Dharman Oct 02 '19 at 12:35
post array is empty and network tab shows proper data – Vaibhav Kakade Oct 02 '19 at 12:42
Check that your method is really POST. From your comment above it looks like it is GET – Dharman Oct 02 '19 at 12:43
Networ shows method GEt but I have used POST in the both the files – Vaibhav Kakade Oct 02 '19 at 12:46
Then you need to investigate where the GET comes from and why. – Dharman Oct 02 '19 at 12:47
does having session affects anything, coz i have session_start on the other page and not on sort.php – Vaibhav Kakade Oct 02 '19 at 12:49
yes you required session on the other page aswell – Ahmed Sunny Oct 02 '19 at 18:02

You have to make following changes in your data object.

function sortby(selectObject) {
        var sortOrder = selectObject.value;
        $.ajax({
            url: "sort.php",
            method: "POST",
            data: { "sortOrder": sortOrder }, // the var you have get from DOM to sent to PHP code
            success: function(data) {
                $('#allProducts').html(data);
            }
        })
        console.log("called");
    }

sorOrder indes is looked into $_POST[] array but it can't found and hence it return you notice.

Thanks everyone, issues is solved. I used type instead of method. :) — Vaibhav Kakade, Oct 05 '19 at 04:18
