Deserialization of Untrusted Data You should never ever deserialize untrusted data. This can lead to https://owasp.org/www-community/vulnerabilities/PHP_Object_Injection . There is also no reason to transmit data as a serialized object, especially if it's only two strings. HTTP already has an easy way to transmit two strings. Username in Form You supply both a user session and a username. This is redundant information and can lead to user impersonation. Generally, the session should already be associated to the user it belongs. There should be a table somewhere in an in-memory database like: UserId Session ExpiresAt 71257 5ad9aff42efa15cd307f3b467e4a8de4 1632926752 88141 15cff5a3776d357ac508e6631f9787a8 1632934962 71004 2caee914979fe4e3a8a36c2ae48632f7 1632911671 ... ... ... If the username is stored both with the session and given as a request parameter, then one of these is ignored. If it's the one in the request parameter, then you're safe. If it's the one in the session, then you can easily forge requests coming from anyone and impersonate any user, as long as you know their username or user id. Given what you said in your question, I assume the latter is the case.

Well, if you need to be quick, I'd be in the forehead personally.Client - first requestThe server is the answer "ok, request accepted,"The client (on the first reply) goes to the cycle, and once in X seconds asks the server "what is it?"The server responds to "nothing, wait," or "first stage is ready" (then the client responds to stage one, and goes back to the cycle, but is waiting for phase two) etc.For this reason, the long-lost processor on the server has to leave the infu about the status of the request (e.g. processing status) and the crypt that accepts the requests "Nothing there" simply looks at the status and says "this is the stage."Well, if it's on the mind, the crypt that accepts the first (initiating) request should not be processed by itself, but in turn, put and maintain the status of "nothing done," but the processing should be done by a single demon, or a separate crypt, which wrestling around the crown, does some volume and will dry.

Try this. $("#button").on("click", function (e){ e.preventDefault(); var message = $("#text").val(); $.ajax ({ url: "iframe.php", type: "POST", data: {message}, dataType: "html" }); }); $("#button").on("click", function (e){ e.preventDefault(); $.ajax({ url: "chat.html", cache: false, success: function(html){ $("#content").html(html); } }); });

Yours. input'a is the identifier. id='text'And you're begging him. Put it in the variable to the variable. $.ajax:var msg = $('#text').val(); $.ajax ({ ... data: msg, ... Only dataType writes a format in which data will be sent to the server, in your case json:dataType: "json"

Each reference to the page should have its id, e.g. reference to page1.php it will be id="page1"♪Now you just write:$('#page1').click() { //если нажали на page1.php } $('#page2').click() { //если нажали на page2.php }

There are no mistakes in the php code. json and use it instead xml) Also if, after the code in question, foodstore.php We're doing some kind of surgery after. echo '</response>'; You can write. exit();♪It's a very bad practice to send every second a request for a server if you don't need it. The request (to complete the data) should be sent only after the change in the input value, i.e., it would be better to hang the sub-worker to change the value:var input = document.getElementById('userInput'); input.addEventListener('keyup', function() { alert('input changed to: ', input.value); // только после изменения вызываем process process(input.value); }); Function createXmlHttpRequestObject (if you don't need backup to old IE, PARE7) you can remove and do this:var xmlHttp = new XMLHttpRequest(); Functions handleServerResponse and process loyalty except the challenge process Every second: setTimeout('process()',1000);♪ Body onload="process()" We have to remove it, too.HTML:<div>Enter food : <input type="text" id="userInput" /></div> <div id="underInput"></div> JS:var input = document.getElementById('userInput'); input.addEventListener('keyup', function() { // alert('input changed to: ', input.value); process(input.value); }); var xmlHttp = new XMLHttpRequest(); function process(inputValue) { var food = encodeURIComponent(inputValue); xmlHttp.open('GET', 'foodstore.php?food=' + food, true); xmlHttp.onreadystatechange = handleServerResponse; xmlHttp.send(null); } function handleServerResponse() { if(xmlHttp.readyState == 4 && xmlHttp.status == 200){ xmlResponse = xmlHttp.responseXML; xmlDocumentElement = xmlResponse.documentElement; message = xmlDocumentElement.firstChild.data; document.getElementById('underInput').innerHTML = '<span style="color:blue">' + message + '</span>'; } else{ alert('Something went wrong!'); } } It's also always possible to see what's coming back to the server.Ctrl+Shift+Imove on to the deposit Network)And yes, don't read the articles from the resource where you found this lesson, they're very outdated.

Probably just a little old-fashioned. json_encodeexample:if (Yii::app()->request->isAjaxRequest) exit(json_encode($data));

If I understood the question correctly, AJAX would help you. Since there is no detail, the answer will be synthesized - https://ru.wikipedia.org/wiki/AJAX Example:$(document).ready(function () { $('#btnSendMessage').click(function (event) { event.stopPropagation(); var data = { 'message': $('#TextBoxSender').val(), } $.ajax({ url: 'MessageHandler', type: 'POST', data: JSON.stringify(data), cache: false, dataType: 'json', processData: false, contentType: "application/json; charset=utf-8", success: function (data) { if (data == true) { alert("Сообщение доставлено"); location.reload(); } else { alert("Внимание! Сообщение не доставлено!"); } }, error: function () { alert("Произошел сбой бла бла бла"); } }); }); ♪Method of communication:[HttpPost] public JsonResult MeesageHandler(string data) { var result = "Сообщение " + data + "принято" return Json(result); }

Good afternoon, your code doesn't quite understand what. I can explain on my fingers how easy it is to use ajax in wordpress.Build a page, give her a sludge (e.g. ajax) and create a template for this page (page-ajax.php)//Тут ставим действие или событие по которому мы будем отправлять запрос на нашу страницу //не обязательно использовать таймер setTimeout(function () { //Раз мы работает с JQUERY, то используем JQUERY //Первым параметром передаем адрес нашей страницы, а вторым параметром callback функцию которая примет то, что мы напишем в шаблоне page-ajax $.post('/ajax', function(data){ alert(data); }); }, 1000); <?php global $wpdb; echo $wpdb->get_var("select count(*) from wp_users"); //У тебя может отличатся название таблицы, если оно не wp_users, замени.

So, async: falsethat's not the same. They're in line.$a = ["url1", "url2", ... "url24"]; $.each($a, function(k, v){ setTimeout(function(){ $.ajax({ url: v }); }, k * 125); }); 125 is 1/8 seconds; k is a mass index, but better an in time variable

AngularJS works a little wrong. To send the parameters as you want, you need to turn them in. {params : {formula: input_value}}♪ It should be:self.calculate = function (event) { var input_value = event.currentTarget.value; console.log(input_value); $http.get('base/calc_logic.php?t=1', {params : {formula: input_value}}) .success(function (data) { console.log('success'); console.log('data:', data); }); };

Decision: To use the event 'afterValidateAttribute'. $('form').on('afterValidateAttribute', function (event, attribute, message) { if (attribute.name === 'samname') { $.ajax({ url: "url-to-action", type: "POST", dataType: "json", data: $(this).serialize(), success: function(response) { if ( typeof(response["form-samname"]) != "undefined" && response["form-samname"] !== null ) { // code here } }, }); return false; } }); Source: https://yii2-cookbook.readthedocs.io/forms-activeform-js/

PHP works on the side of the server, JS on the side of the visitor and there is no direct link between them. PHP only generates a page. ♪ ♪ The only chance you're going to have to accomplish your task (not seeing how wrong it is itself). Generate page according to condition<?if ($num==2):?> <script> function test2(){ .... }; test2(); </script> <?endif?> That is, the scr placed on the page only if the conditions are met.But if I were you, I'd think about the right task.

A little lire.Format https://ru.wikipedia.org/wiki/JSONP presupposes a revolving function around data transfer. It allows JSONP to use the answer as a complete JavaScript code and use it in the body of the current. <script>♪ This is what makes it possible to make cross-country requests.A typical example of the server response in JSONP is:callback123({"foo": "bar"}); In contrast to JSONP, the JSON format does not contain a revolving function and, strictly speaking, is not a fully valid JavaScript code. A typical server response in JSON is:{"foo": "bar"} If you put that answer in the gate <script> that JavaScript passer should give you a syntax error.SyntaxError)Now your problem.In the client code, you're demanding an answer from the server in JSONP, and you're returning an ordinary JSON. This is a problem. To make it work, it's enough to give the old JSONP:header('Access-Control-Allow-Origin: *'); $this->response->addHeader('Content-Type: application/javascript'); $data = array( 'test1' => 12, 'test2' => 'good' ); $this->response->setOutput(sprintf( '%s(%s);', $this->request->get['callback'], json_encode($data) ));

PhantomJS needs to do this or Selenium, but it's not a simple task, and it's going to have to be hard.

You can take json. To this end, move the json-start and put it in your code server.$('#Send').click(function(){ $.post('333.php',{ send1:JSON.stringify(arr) }, function(data) { $(".result").html(data); }); });

Answer to your question:It'll be as fast as you described in the first option.But how do you not shoot yourself and your users with a knee?At least you can save your legs by refusing JavaScript. And AJAX. Seriously... I understand JavaScript, he can be used to invent a bicycle in particularly desperate cases, but AJAX somewhere? AJAX should be avoided in general by designing and designing the site with few exceptions (the nature of the endless tape of content as the WCOF).Create two menus and put them somewhere in your mark:<nav class="menu-mobile"></nav> <nav class="menu-desktop"></nav> And add some of that CSS:.menu-mobile, .menu-desktop { display: none; } /* Для планшетов и меньше */ @media (max-width: 991px) { .menu-mobile { display: block; } } /* Для "квадратных" десктопных мониторов и выше */ @media (min-width: 992px) { .menu-desktop { display: block; } } That's it. The best. an unresourced and fast way to come up with. No JavaScript and no AJAX. And not to be ashamed of others.

If you want to work on dynamically created references, use the function. http://api.jquery.com/live/ ♪ If you don't just have a clicked reference, you probably get the same data, so you don't see the difference.

If you don't have an address for jQuery: $(function(){ location.reload(); _
