ajax type POST POST method to php

Question

I m trying to use the POST method in jQuery to make a data request  So this is the code in the html page    lt form gt  Title    lt input type  text  size  40  name  title   gt   lt input type  button  onclick  headingSearch this form   value  Submit   gt  lt br   gt  lt br   gt   lt  form gt   lt script type  text javascript  gt  function headingSearch f        var title f title value        ajax         type   POST         url   edit php         data   title title          success  function data                center   html data                       lt  script gt    And this is the php code on the server     lt  php   title     POST  title    if  title              echo  title       gt    The POST request is not made at all and I have no idea why  The files are in the same folder in the wamp www folder so at least the url isn t wrong

You need to use data   title  title  to POST it correctly   In the PHP code you need to echo the value instead of returning it

Id advice you to use a bit simplier method -    post  edit php    title     input name  title     val      function resp       alert resp         try this one  I just feels its syntax is simplier than the   ajax s one

Check whether title has any value or not  If not  then retrive the value using Id    lt form gt  Title    lt input type  text  id  title  size  40  name  title  value       gt   lt input type  button  onclick  headingSearch this form   value  Submit   gt  lt br   gt  lt br   gt   lt  form gt   lt script type  text javascript  gt  function headingSearch f        var title jQuery   title   val          ajax         type   POST         url   edit php         data   title title          success  function data            center   html data             lt  script gt    Try this code   In php code  use echo instead of return  Only then  javascript data will have its value
