When using wp_redirect() you will facing Header error “PHP Warning: Cannot modify header information – headers already sent by …… wp-includes/pluggable.php on line 1228”
To solve this problem you need to change the PHP.ini value. In PHP.ini find
var ajaxurl = '<?php echo admin_url() ?>admin-ajax.php'; jQuery(document).ready(function () { jQuery.ajax({ url: ajaxurl, data: { //This action must same with the PHP function name "action": "ajax_request", "params": "wordpress ajax" }, success:function(data) { //This is the result return from PHP function console.log(data); }, error: function(errorThrown){ //This is the error return console.log(errorThrown); } }); });
$(document).on("keydown", "#number", function(e) { var key = e.charCode || e.keyCode || 0; if (key == 8 || key == 9 || key == 13 || key == 46 || key == 110 || key == 190 || (key >= 35 && key <= 40) ||(key >= 48 && key <= 57) || (key >= 96 && key <= 105)) { return; } else { return false; } });
