Now, I want to check if the user put in the right result of the addition! Do I do this on the page register.php? Or, do I do this in the same file (index-wamp.php)? And so on.
I want to know how to process form data.


I think I solved it.
<form action='<?php if ($answer === $hausin) { echo "register.php"; } ?>' method='POST'>

I'm trying to figure out how to get the variable $_GET to work so that the H1 tag turns into what the user imputted

The question I'm trying to answer is below
Create a new PHP file named lab2.php.
Inside, add the HTML skeleton code and give its title “Lab Week 2"
Within the body tag, create a h1 tag that says "Enter the name of your favourite musical artist"
Add a section tag inside the body tag.
Create a form tag and use the $_GET method to get users to input their favorite artist. Store the user input into variables.
Create a submit button for the user to input their favorite artist.
Check whether the variable is empty or not.

i'm gonna hazard a guess and asume that this is some sort of educational task.
but nevertheless here is how i understand the tasks.

//3.Within the body tag, create a h1 tag that says "Enter the name of your favourite musical artist"

} else {

Now if this is some sort of test don't just copy of the internet. Do some fiddling around with the code and try to learn something :-)

solving problems in session? [closed]

Improve this question
I have created two pages , one is index.php and admin.php . In the first page or index.php , i have created a loggin form so that i can access the admin.php page trough the loggin or like this enter image description here
Now by logging in i go to admin.php page. Here is the question what i want to ask about that now when ever i click the back button or next button in the chrome. I am returning to the admin.php page . I have tryed the session_start() and the if(!isset($password) || !isset($user)){}. But this code for obvious reasons doesnt work . So can someone help me out with this ?
The code for the example is here index.php
<?php
session_start();
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel="stylesheet" href="style.css">

</div>
<form action="inc/login.php" method="POST"><br>
<p class="title">Log In</p>
<label for="Username">User :</label>
<input type="text" name="username" id="user"> <br> <!--username -->
<label for="Password">Password :</label>
<input type="password" name="password" id="password" ><br><br> <!-- password -->

<input type="checkbox" name="checkbox" id="chk" ><br><br> <!-- checkbox -->
<input type="submit" name="submit" value="Log in" > <!-- enter -->
</form>
<?php
if(!isset($_GET['Login'])){
exit();
}else{
$check=$_GET['Login'];
if($check=="userEmpty"){
echo "<p class='class_login'>user is empty</p> ";
}elseif($check=="passwordEmpty"){
echo "<p class='class_login'>password is empty</p> ";
}elseif($check=="wrongUser"){
echo "<p class='class_login'>user is wrong</p> ";
}elseif($check=="Password"){
echo "<p class='class_login'>password is wrong</p> ";
};
} ;
?>
<script src="js/main.js"></script>
</body>
</html>
and the code for the admin.php is this one :
<?php
session_start();
if(!isset($username) || !isset($password)){
header("location:index.php?data=closed");
exit();
}
?>
<!DOCTYPE html>

</head>
<body>
<div class="top">
Log Out
</div>
</body>
</html>

Besides using of session_start you need to store something in the session, using something like this:
$_SESSION['userId'] = <value>;
which must be set in your login.php and checked by your admin.php if user has access rigths to visit secured page. I.e. you need to check:
if (isset($_SESSION['userId']) && $_SESSION['userId'] == <value>) {
// access granted
}

Simple PHP to process HTML Form

I am sure this is very simple to many of you!! I am trying to learn basic HTML / PHP form processing. The site is hosted on a local Apache server. I have had PHP working correctly and am happy that the server is working fine.
I have two files, one is settings.html, where the user has a form of 3 elements which they can enter some float values into (humidity, temperature and light tolerances). The submit button triggers a separate file called process.php which should display the three values. The code is as follows:
settings.html:
<!DOCTYPE html>
<html>
<head>
<meta content="text/html; charset=ISO-8859-1" http-equiv="content-type">
<meta http-equiv="refresh" content="179" >
<title>Sparks - Settings</title>
<link rel="stylesheet" type="text/css" href="css/default.css">
</head>
<body>
<div id="logo">
<img style="width: 335px; height: 142px;" alt="ESP8266 Logo" src="images\imgESP8266.png">
</div>
<br>
<form method="post" action="php/process.php">
Humidity Tolerance : <input type="float" name="humTolerance" placeholder="Enter %" /><br />
Temperature Tolerance : <input type="float" name="tempTolerance" placeholder="Enter %" /><br />
Light Tolerance : <input type="float" name="lightTolerance" placeholder="Enter %" /><br />
<input type="submit" value="Submit" />
</form>
</body>
<html>
php/process.php:
<?php //process.php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
$humTolerance = $_POST["humTolerance"];
$tempTolerance = $_POST["tempTolerance"];
$lightTolerance = $_POST["lightTolerance"];
}
echo <<<_END
<html>
<head>
<meta content="text/html; charset=ISO-8859-1" http-equiv="content-type">
<meta http-equiv="refresh" content="179" >
<title>Sparks - Settings</title>
<link rel="stylesheet" type="text/css" href="css/default.css">
</head>
<body>
humTolerance is: $humTolerance<br>
tempTolerance is: $tempTolerance<br>
lightTolerance is: $lightTolerance<br>
</body>
</html>
_END;
?>
This is producing the HTTP ERROR 500 and I can't see why. Please can I have some help? Thanks.

As I said in comments:
"the (first) problem is in your heredoc closing identifier it contains spaces before it."
and
"the second one: type="float" isn't a valid type for an input"
You need to replace those input types with ones that are valid.
https://developer.mozilla.org/en/docs/Web/HTML/Element/input
Note that not all browsers support certain HTML5 attributes, see the above as a reference.
So use type="number" or type="text".
PHP with spaces removed before the closing heredoc identifier.
<?php //process.php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
$humTolerance = $_POST["humTolerance"];
$tempTolerance = $_POST["tempTolerance"];
$lightTolerance = $_POST["lightTolerance"];
}
echo <<<_END
<html>
<head>
<meta content="text/html; charset=ISO-8859-1" http-equiv="content-type">
<meta http-equiv="refresh" content="179" >
<title>Sparks - Settings</title>
<link rel="stylesheet" type="text/css" href="css/default.css">
</head>
<body>
humTolerance is: $humTolerance<br>
tempTolerance is: $tempTolerance<br>
lightTolerance is: $lightTolerance<br>
</body>
</html>
_END;
?>
Use PHP's error reporting also:
http://php.net/manual/en/function.error-reporting.php
If you don't have access to logs, then set that to catch and display.

Sacred Purity (hereinafter referred to as "we" and/or "us") operates FOB shipping point, freight prepaid. This means that the responsibility for the goods transfers
from us to buyer (hereinafter referred to as "you") the moment the package leaves our warehouse. Therefore we are NOT responsible for delays, losses, damages,
thefts, confiscations, additional postal fees in transit or at destination, taxes, etc. This list of events we are NOT responsible for is incomplete and may change
at any time. All claims about missing / damaged / delayed / confiscated / modified merchandise must be made directly with the shipping carrier, NOT us.
You should buy shipping insurance if you feel you need it, please contact us if you decide to insure your package. A processed order usually ships within two business
days unless noted, and we make a best effort to ship within one business day. For temporarily out of stock items or delayed shipments, you will be contacted by e-mail
or telephone. Our website does not display quantities available because the turnover is continuous. If an item is permanently unavailable or discontinued, the charge
will be voided or a complete refund will be made to your card. We will notify you if this occurs. Unless otherwise noted, all items ship directly from our shop base in
Thailand. Contact us via e-mail for alternative shipping method / carrier, special
orders or larger orders that you think warrant an insurance.
<br><br>
It is the sole responsibility of the client/buyer to ensure that the items ordered from our online store are permissible for mailing/receipt in the destination country.
We assume absolutely no responsibility for issues arising due to ordering prohibited/restricted items and any subsequent customs/legal issues in the destination or
transit countries. We are not responsible for any additional customs charges or fees once your package has left our facility. Customs charges and fees are the sole
responsibility of the purchaser. If you are unfamiliar with customs regulations, fees and charges, please speak to your local postal or customs office for more information.
If customs fees and charges are refused at the time of delivery, your order MAY be returned and you will not receive a refund for shipment costs. If a package is lost
in transit, confiscated by authorities, damaged, stolen, etc we are NOT responsible and the issue should be taken up with the local postal, custom, and law enforcement
authorities. Again, once a package is shipped we have no responsibility for it and we will offer no refund if something happens to it after shipping. If the package
is returned to us as undeliverable, please contact us to discuss what can be done to send it again.

Assuming your RedirectToURL is a function which accepts parameter as URL. try including below code in your function. if no headers are sent after the php closing tags it will directly set the headers to $url or else will use the javascript redirection.
function RedirectToURL($url)

Button type in a form, with a control script in php page not working as expected

I already posted something similar but I didn't receive good answer mainly for my fault, my way to ask wasn't good.
Now I prepared an example to explain what I'm looking for:
I've got a php file with a form and a control script in it, so I post you the stripped example versions:

<button onclick=\"submit();\">Inserisci!</button>
<!-- <input type=\"Submit\" id=\"Submit\" name=\"Inserisci\"/> -->
</div>
</form>
";
?>
<!-- </div> -->
</body>
</html>
So there is a simple function that controls the only input field.
The php file called does a bunch of things, I've stripped it down to only this.
<?php
require_once("insert_ok.html");
# header('Location: insert_ok.html');
?>
So it only redirects to another page.
My problem is that if I use "input type=\"Submit\" on the first file it works correctly, and if I enter nothing in the filed it stops me, while if I use button onclick=\"submit();\ even if the input field is empty I get the error from the function but then the script let me proceed to the next page.
can you help me?

change
<button onclick=\"submit();\">Inserisci!</button>
to
<button onclick=\"return controllo(document[insert]);\">Inserisci!</button>
