No added datainto database, and not shown in table append using AJAX and PHP

Question

I am still in the same problem in this link here. So, I used the append method. And here is the AJAX code:

Answer 1

[1] Why are you catching value of a button

var selectW = $('#insert_new').val();

I think there is no need for that.

[2] Add this before ajax call

dataString = 'selectW='+ selectW + '&select_at='+ select_at + '&pay='+ pay+ '&facture='+facture+ '&select_opt='+ select_opt;

[3] In ajax call set `data' as

data: dataString,

instead of

 data: {'text': insert_new, 'text': selectW, 'text': select_at, 'text': pay, 'text': facture, 'text': select_opt},

[4] Why are you catching response, you are not sending any string back from insert_buy.php

          if(response=="success")
          {

as you are not getting return value as "success", else part is getting executed and getting alert message as "No data added".
