jquery - OnClick Function Get Next Record PHP AJAX MYSQL -


i getting stuck example found on topic. see original article: how show next result in mysql on "onclick" in javascript?

i followed example t, exception of using updated functions. anyway, getting stuck on 1 step, hoping explain.

within jquery below, code setting $number , passing number in post action php file. problem is when echo 'count', echos "$number". not sure why not passing actual number such "0" rather string "$number". doing wrong, not sure going on.

jquery

$(function(){   $('#showmore').click(function(event) {      event.preventdefault();      $number = $('.result').size();      $.ajax({        type: "post",        url: "getnext.php",        data: "count=$number",        success: function(results){          $('#results').append(results);        }      });    });

php
passing count variable can use in query, so:

$pst = $_post['count'];

sql

$sql = "select * tablename limit $pst,1";

i went ahead , captured error receiving (see below) - mentioned inserting "$number" instead of actual number.

"fatal error: query failed! sql: select * tablename limit $number,1

any appreciated

problem sending count string $number in case.

your data should be

data: {"count":$number}, //notice `"`

send object.

or 

$data:"count=" + $number,

concate var

i prefer data object more readable.
