AJAX文件在在线服务器上造成了一些问题，但离线运行良好

Question

在使用这些链接和通过代码进行验证时，我无法添加或编辑数据，但是当网站处于脱机状态时，成功添加，删除和编辑了数据。无法弄清楚。

我有一个名为category.php的文件，该文件具有与此文件的连接，没有该文件，我可以轻松地添加或编辑数据，但是此文件是必需的。

var manageCategoriesTable;

$(document).ready(function() {
	// active top navbar categories
	$('#navCategories').addClass('active');	

	manageCategoriesTable = $('#manageCategoriesTable').DataTable({
		'ajax' : 'php_action/fetchCategories.php',
		'order': []
	}); // manage categories Data Table

	// on click on submit categories form modal
	$('#addCategoriesModalBtn').unbind('click').bind('click', function() {
		// reset the form text
		$("#submitCategoriesForm")[0].reset();
		// remove the error text
		$(".text-danger").remove();
		// remove the form error
		$('.form-group').removeClass('has-error').removeClass('has-success');

		// submit categories form function
		$("#submitCategoriesForm").unbind('submit').bind('submit', function() {

			var categoriesName = $("#categoriesName").val();

			if(categoriesName == "") {
				$("#categoriesName").after('<p class="text-danger">Brand Name field is required</p>');
				$('#categoriesName').closest('.form-group').addClass('has-error');
			} else {
				// remov error text field
				$("#categoriesName").find('.text-danger').remove();
				// success out for form 
				$("#categoriesName").closest('.form-group').addClass('has-success');
