I am trying to paginate some results on keyup. everything is working as intended but not the pagination. how it works is that when I search it has to take my search string from the main page to the searchparent.php and query the database and return the results in paginated table. I get the first page to work but when I click the next button the URL redirects to the seachparent code. Please kindly help. Please see the code below.
<!DOCTYPE html>
<script>
$(document).ready(function(){
$("#serachbox").keyup(function(){
var Search= $("#serachbox").val();
if(Search.length < 1)
{
$("#show").html("");
}
else
{
$.post('searchparent.php',{Search:Search,HiddenA:HiddenA},function(data)
{
$("#show").html(data);
});
}
});
});
</script>
</head>
<body>
<input id ="serachbox" type="text" placeholder="Type learner surname" name="Send" style="width:400px;height:30px;display:none;"/>
</body>
