Pass Javascript variable to another page via PHP Post

I am having two php pages:
page 1:
<form class="form-horizontal" role="form" method="post" action="Page2.php">
<button id="place-order" class="btn btn-lg btn-success">Place Order</button>
<div id="ajax-loader" style="display:none;"><img src="images/ajax-loader.gif" /></div>
</form>
<script>
var id = Math.random();
$(document).ready(function() {
$('#place-order').on('click', function() {
$(this).hide();
$('#ajax-loader').show();
});
});
</script>
As on form, it redirects to Page2.php, I want to pass the Javascript variable "id" from Page1 to receive it in Page2.
I have tried using cookies, but need an alternative approach.
I am not understanding the transistion from PHP to JS and vice-versa. Help is appreciated.
Thanks in advance
Dear you can do it very easily with ajax. Ajax has data attribute which helps you pass your data from javascript to another page.
This link will help you a lot
https://api.jquery.com/jquery.ajax/
You can use session storage or cookies.
Example for session storage:
// First web page:
sessionStorage.setItem("myVariable", "myValue");
// Second web page:
var favoriteMovie = sessionStorage.getItem('myVariable');
You could use a query string to pass the value to the next page.
Add an ID to the form
<form class="form-horizontal" role="form" method="post" action="Page2.php" id="order-form">
Update the action of the form to add this query string from our JS variable
var id = Math.random();
$('#order-form').attr('action', 'Page2.php?id=' + id);
Get this variable in PHP (obviously you might wanna do more checks on it)
<? $id = $_GET['id'] ?>
We can now use $id anywhere in our PHP and we'll be using the ID generated from JS. Neat, right? What if we want it in JS again though? Simply add another script tag and echo it there!
<script type="text/javascript">
var id = <? echo $id ?>;
</script>
EDIT: Updated to add a little about how it works as you said you're not too sure about the transition between PHP and JS.
PHP runs on the server. It doesn't know much about the browser, and certainly doesn't know about JS. It runs everything and finishes executing before the web page is displayed. We can pass PHP variables to JS by creating script tags and creating a new javascript variable, echoing the PHP value.
JS (JavaScript) runs in the browser. It doesn't know about anything that happens on the server; all it knows about is the HTML file it is running in (hit CTRL+U to see raw HTML). As JS runs at a completely separate time to PHP there is no easy way to transfer variables (e.g. $phpVar = myJSVar). So, we have to use server methods like POST or GET.
We can create a GET or POST request in 2 main ways:
Using a form
Using an AJAX request
Forms work in the way I've outlined, or you can create a hidden field, set the value you want and then check for that. This involves redirecting to another page.
AJAX (Asynchronous Javascript And Xml) works slightly differently in that the user doesn't have to leave the page for the request to take place. I'll leave it to you to research how to actually program it (jQuery has a nice easy API for it!), but it basically works as a background request - an example would be displaying a loading spinner whilst loading order details from another page.
Hope this helps, let me know if something's not clear!

How to get a DIV element from an external webpage in HTML file?

Apologies in advance if this question has been asked earlier. I did find some similar questions on web but I couldn't figure out the answer still. You can say I have never dealt with anything beyond basic HTML. So any help would be appreciated.
I have a HTML file (Say text.html) only for personal use. In the file, there will be an input box for entering text and a submit button. I want that if I clicks on submit, it opens a particular hyperlink from an external webpage based on the input text. I guess it's like "I am feeling Lucky" of Google.
Example: If the user enters "Test" and clicks on Submit, it should open the second result from the page "https://www.google.com/search?q=test"
Here is my HTML:
<!DOCTYPE html>
<html>
<body style="background-color:beige">
<h1 style="text-align:center"><font size="14">Test</font></h1>
<style type="text/css">
</style>
<form id="form">
<div align="center" style="vertical-align:bottom">
<input type="text"
value="Test"
id="input"
style="height:50px;width:200px;font-size:14pt;">
</div>
</form>
<TABLE BORDER="0">
<TD><button class="button" id="button01">SUBMIT</button></TD>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$('#button01').click(function(e) {
var inputvalue = $("#input").val();
window.open("https://www.google.com/search?q="+inputvalue);
});
</script>
Also, here is the example of the div element from the page on which the hyperlink I want to open is on:
<div id="XYZ" class="contentEditValue" style="float:left;width:180px;">
2nd Result
</div>
I have read that it can be achieved with PHP or Jquery and all but they are not something I have ever worked on. Thank you very much in advance for any help!
Appreciate any other alternatives as well.
You shouldn't be able to do that because of security. If that (reading content from iframes, other browser windows...) would be possible, an attacker could add JS keylogger to your internet banking login or read your messages on Facebook. CORS (https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS) is used to block these requests and if the website doesn't say explicitly that you are allowed to do something with its content, most browsers won't allow you that.
You have are missing a }); to close the ready() function
<script type="text/javascript">
$(document).ready(function(){
$('#button01').click(function(e) {
var inputvalue = $("#input").val();
window.open("https://www.google.com/search?q="+inputvalue);
});
});
</script>
Here's a basic example of how to do this in PHP.
Taking JavaScript/JQuery out of the picture, let's just say you have a basic form:
<form>
<input type="text" value="Test" name="input">
<input type="submit">
</form>
Without specifying action or method attributes on the <form> tag, the form will make an HTTP GET request to the URL of the page it is on, so for this example the PHP code will be on the same page as the form. Here's a more detailed description of sending form data if you're interested.
Now that you have a way to pass the input to the PHP script*, there are three basic parts to this problem.
Make a request to the page you want with a query string including your input
http_build_query is an easy way to construct a properly encoded query string to use with your request. For this example we'll use file_get_contents to make the request. There are other ways to do it, including cURL, but let's keep it simple.
$query = http_build_query(['q' => $_GET['input']]);
$page = file_get_contents('http://www.example.com/?' . $query);
I'm not using Google for this example because it's a bit more complicated to find the right links in the response and follow them. (Partially because they don't really want you to do it that way.)
Find the link you want in the response
Don't try to find the link in the response with regex. You'll have problems with it, come back to Stack Overflow to try to solve them, and people will tell you that you shouldn't be using regex, so just skip that part and use a DOM parser.
$doc = new DomDocument;
$doc->loadHTML($page);
$links = $doc->getElementsByTagName('a');
$url = $links[0]->getAttribute('href');
I used getElementsByTagName() to find links, but if the page is more complex an xpath query will work better. Also, I used the first link ($links[0]) because example.com only has one link. $links[1] would get you the second link if it existed.
Follow the link
header("Location: $url");
exit;
If everything goes well, you'll end up where you want to be. But there are a lot of things that can go wrong. If you're requesting a resource that you have no control over, it can change at any time without any advance warning to you, so your code that finds the link may stop working. You may get blocked from making requests. Scraping links from sites like this violates the terms of service on many sites, so check that out beforehand. You may find that the site offers a web API, which should be a much better way to access its content than this.
*You don't really need a form for this; you can just pass the input parameter in the URL to your page.

reCaptcha not shows on my singlepage website

I have some problem with the recaptcha loading.
I trying to remake and modernize one of old my website to a singlepage one with php, javascript and ajax (no jquery!).
Everyting is fine yet, but the recaptca. I use the following method.
index.php contains the "main frame" and the target divs to the HTTPRequest function.
With AJAX I load the PHP page templates to the main target divs.
BUT when my PHP template file looks the following to show the registration last page with the captcha:
<?php
$template = '
.../ some code sits here /...
<div class="w80">
<div class="g-recaptcha" data-sitekey=".../ my sitekey sits here /..."></div>
</div>
<div class="flex-row fr-c mt50a">
<button class="button btn-reg" onclick="switchPage(\'registration_page_2.php\')">« Back</button>
<button class="button btn-reg" onclick="validatePage(\'registration_validate.php\')">Submit your registration</button>
</div>
';
echo $template;
and I load it into one of my divs, the reCaptcha has not been shown. I tried some ways and tricks, but it's not working.
There is no form and submit section at all on my page. I do it with javascript and ajax.
Why I cannot make it works?
Is that possible to bypass form->submit->post method to get reCaptcha alive?
Or is the singlepage the wrong way?
I don't quite understand you but since i can't post a comment, i will attempt to answer anyway.
You don't have to use php to echo the html code, just in-case you didn't know, you can do it like this.
<?php
//php code
?>
<div class="w80">
<div class="g-recaptcha" data-sitekey=".../ my sitekey sits here /..."></div>
</div>
<div class="flex-row fr-c mt50a">
<button class="button btn-reg" onclick="switchPage('registration_page_2.php')">« Back</button>
<button class="button btn-reg" onclick="validatePage('registration_validate.php')">Submit your registration</button>
</div>
<?php //continue code here ?>
and I load it into one of my divs, the reCaptcha has not been shown. I
tried some ways and tricks, but its not works :(
It's hard to tell from the information you have given why it is not being shown
There is no form and submit section at all on my page. I do it with
javascript and ajax.
If your registration_page_2.php and registration_validate.php does not echo the template in your current .php shown, then it certainly wouldn't appear on your page
Why I cannot make it works? Is that possible to bypass
form->submit->post method to get reCaptcha alive? Or is the singlepage
the wrong way?
I think you just did something wrong in the middle. The way you have said is 'form->submit->post' is the right way to go about this
Can you help me to get the solution please?
Using your browser, inspect or view the source code of your page. (For google chrome the hotkey is CTRL+SHIFT+I) Try to find the elements in your page to see if they are loaded, but hidden due to css or the likes. After which, you should give more details.
update your captcha block with adding id recaptcha
<div class="g-recaptcha" id="recaptcha" data-sitekey=".../ my sitekey sits here /..."></div>
add following code in your page load
<script src='https://www.google.com/recaptcha/api.js?hl=en&render=explicit&onload=onReCaptchaLoad'></script>
<script type="text/javascript">
var recaptcha;
var onReCaptchaLoad = function(){
recaptcha = grecaptcha.render('recaptcha',{
'sitekey' : 'YOUR_RECAPTCHA_PUBLIC_KEY',
'theme' : 'white'
});
};
</script>
You can do it with php request
<?php
if(isset($_POST['g-recaptcha-response']) && !empty($_POST['g-recaptcha-response'])){
$recaptcha = $_POST['g-recaptcha-response'];
$recaptcha_secret = 'YOUR_RECAPTCHA_SECRET_KEY'
$verify = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret={$recaptcha_secret}&response={$recaptcha}");
$captcha_success = json_decode($verify);
if($captcha_success->success){
// success
}else{
// error
}
}
?>

I am trying to create a JSP Page with frames

I am trying to create a JSP page which will contain multiple section. Each section will contain data fetched from data base using servlet. I tried using frame and have put frame src ="servlet" and in servlet data is being fetched and forward that to jsp which I want to be displayed inside the frame?? Anyone having some idea for this.
I often want to achieve similar things and do so by setting attributes on the HttpServletRequest object.
Servlet:
User user = userBean.getUser(231);
Job job = user.getJob();
request.setAttribute("user",user);
request.setAttribute("job",job);
request.getRequestDispatcher( url ).forward(request, response);
JSP Page
<div id="section1">
${user.name}
${user.age}
</div>
<div id="section2">
${job.title}
${job.wage}
</div>
Notes
Frame is an old HTML Element and not compatible with HTML5
I've used divs in my example, but you could use HTML5 Section to provide more smeantic meaning.
Hope I've understood your problem and this helps.
Good luck

How to get information from Javascript to MySQL database using PHP?

(NEWBIE ALERT)
Hello! I am working on developing a database that stores information that people enter onto these online surveys. I don't have experience with Javascript, but I have worked with PHP and MySQL before. I am currently stuck on how to store the data to the database. Here are a few things about the code:
The person that created the online surveys had the online surveys written in Javascript (saved as HTML files)
Each survey is written in a separate file
Each survey has multiple data to be stored
Every time the user hits the next button, it goes to another page of the survey
I've worked on a project similar to this before, but my forms were only a page, so whenever the user clicks the "Submit" button, I had it go to another webpage written in a separate PHP file (kind of like a "results" page).
WHAT I DON'T UNDERSTAND/NEED HELP ON:
How do I make this so that when the user hits the "Next" button, it not only goes to the next page (what it's doing right now), but also sends the info to be stored in the database?
These surveys should be filled by people on their own computers so the surveys are written in JS (client-side). The storing part should be written in PHP (server-side) and MySQL, correct? Does this mean that I have to create a separate PHP file to create the code for transferring the data to the database or can it all be done in the same file? (I would think that I would need to create a separate file, one for each survey.)
Here's a general structure of how the HTML file:
<!DOCTYPE html>
<html>
<head><link rel="stylesheet" type="text/css" href="survey.css">
<script>
function Q2(){
document.getElementById("Q").innerHTML = "does something...<button type='button' onclick='Q3()'>Next</button>";
function Q3(){
document.getElementById("Q").innerHTML = "does something...<button type='button' onclick='Q4()'>Next</button>";
function Q4(){
document.getElementById("Q").innerHTML = "does something...<button type='button' onclick='Q5()'>Next</button>";
//keeps going until the last question
</script>
</head>
<body>
<h1>Meeting 1</h1>
<p id="Q">Some text...<br><input type="text" name="tweet" style='height: 50px;width: 500px;'><br><br>
<button type="button" onclick="Q2()">Next</button>
</p>
</body>
</html>
I've done a bit of research and looked at a few textbooks. I think AJAX may be something that I need to use? But I'm not too sure. If possible, could someone explain to me what I should be doing? I would like to not only be able to find a solution for this, but understand it as well.
Thank you in advance!!
For sending data to a PHP page using JavaScript, I'd recommend using the jQuery framework, where you can do it in as simple a code as this:
function Q2(){
var tweet = $("input[name='tweet']").val();
$.post("your_receiving_page.php", { data : tweet }, function(response){ //POST to PHP page where $_POST["data"] is the tweet variable
//deal with PHP output here
console.log(response);
if(response=="success"){
//javascript code to go to next page etc.
}
}
}
That way, you make a PHP file called "your_receiving_page.php" (or whatever) and handle the posted data like so:
<?php
$tweet = $_POST["data"];
//do stuff with $tweet, e.g. put it in a database
//...
//then end the code with "success", which is what you're looking for in the JavaScript as a successful callback
exit("success");
