}
$('.common_selector').click(function(){
filter_data();
});
$('#price_range').slider({
range:true,
min:1000,
max:65000,
values:[1000, 65000],
step:500,
stop:function(event, ui)
{
$('#price_show').html(ui.values[0] + ' - ' + ui.values[1]);
$('#hidden_minimum_price').val(ui.values[0]);
$('#hidden_maximum_price').val(ui.values[1]);
filter_data();
}
});
});
</script>
How can I make an ajax call in wordpress without use of plugin?

Answer 1

Ajax code
<script type="text/javascript">
function filter_data(){
$('.filter_data').html('<div id="loading" style="" ></div>');
var action = 'fetch_data';
var minimum_price = $('#hidden_minimum_price').val();
var maximum_price = $('#hidden_maximum_price').val();
var brand = get_filter('brand');
var ram = get_filter('ram');
var storage = get_filter('storage');
var data = {
action:action, minimum_price:minimum_price,
maximum_price:maximum_price, brand:brand, ram:ram,
storage:storage
};
$.post('/wp-admin/admin-ajax.php',data,function(response){
$('.filter_data').html(data);
});
}
</script>
In you function.php file
add_action('wp_ajax_fetch_data','filter_data'); // for loggedin user
add_action('wp_ajax_nopriv_fetch_data', 'filter_data'); // for non loggedin user
function filter_data()
{
$minimum_price = $_POST['minimum_price'];
$maximum_price = $_POST['maximum_price'];
$brand= $_POST['brand'];
$ram= $_POST['ram'];
$storage= $_POST['storage'];
// here your product filter code
}
