I'm trying to use session variable $_SESSION['name'] on the second page i.e review.php.
but it gives me nothing on the second page.How to use Session variable on the second page?
This is index.php
<?php
session_start();
$connect = mysqli_connect('localhost','root','root','review');
if(isset($_POST['submit']))
{
$id = $_POST['id'];
$_SESSION['name'] = $id;
}
?>

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css">
</head>
<body>
<form action="review.php">
<input type="text" name="id" placeholder="id">
<input type="password" name="password" placeholder="password">
<input type="submit" name="submit" class="btn btn-success">
</form>
</body>
</html>
here is review.php
<?php
session_start();
$connect = mysqli_connect('localhost','root','root','review');
if(isset($_SESSION['name']))
{
echo $_SESSION['name'];
}
else{
echo "nothing";
}
?>
You have 2 problem:
You send submitted form to review.php, so you should read form data in review.php
You did not set form method. As default method is GET, but you read $_POST variable. (What is the default form HTTP method?)
So you should change index.php as follow:
<?php
session_start();
$connect = mysqli_connect('localhost','root','root','review');
if(isset($_POST['submit']))
{
$id = $_POST['id'];
$_SESSION['name'] = $id;
}
?>

I don't get the PHP $_SESSION working when I try to echo the result on the first page. The error message states basically that the variables are undefined.
The path i want to use:
1st page = form 1
2nd page = form 2
Go back to 1st page = form 1 with all input filled from previous submit + all data from the 2 forms in a text.
Is that possible ?
Page 1 = index.php:
<?php session_start(); ?>
<!DOCTYPE html>
<html lang="fr">
<head>
<meta name="viewport" content="width=device-width, initial-scale=1" />
</head>
<body>
<form action="overview.php" id="regForm" method="post">
<div class="tab">
<h2>1. Your info</h2>
<p><input type="text" placeholder="Prénom" name="fname" value="<?php echo htmlspecialchars($_SESSION['name']); ?>"></p>
<p><input type="text" placeholder="Nom" name="name" value="<?php echo htmlspecialchars($_SESSION['name']); ?>"></p>
<input type="submit" value="Valider">
</div>
</form>
<?php echo "Your name is :",$_SESSION['name'], "and your first-name is ", $_SESSION['fname'];?>
<?php echo "Your e-mail is :", $_SESSION['email'] ;?>
</body>
</html>
Page 2 = overview.php:
<?php session_start(); ?>
<?php
$_SESSION['fname'] = $_POST['fname'];
$_SESSION['name'] = $_POST['name'];
?>
<form action="index.php" id="regForm" method="post">
<h2>1. Tes informations personnelles</h2>
<p><input type="text" placeholder="e-mail" name="email"></p>
<input type="submit" value="Valider">
</form>
Back to Page 1 = index.php:
<?php session_start(); ?>
<!DOCTYPE html>
<html lang="fr">
<head>
<meta name="viewport" content="width=device-width, initial-scale=1" />
</head>
<body>
<form action="overview.php" id="regForm" method="post">
<div class="tab">
<h2>1. Your info</h2>
<p><input type="text" placeholder="Prénom" name="fname" value="<?php echo htmlspecialchars($_SESSION['name']); ?>"></p>
<p><input type="text" placeholder="Nom" name="name" value="<?php echo htmlspecialchars($_SESSION['name']); ?>"></p>
<input type="submit" value="Valider">
</div>
</form>
<?php echo "Your name is :",$_SESSION['name'], "and your first-name is ", $_SESSION['fname'];?>
<?php echo "Your e-mail is :", $_SESSION['email'] ;?>

Do you guys see any issue that prevents the code to run ?
Just found out the "WHY".
I basically blocked cookies when I started the project which prevent $_sessions to work properly.
So make guys sure that cookies are enabled on your website. The kind of things that waste an hour of work ...
So the goal is to take the input from a form append it to the end of the URL and then return the HTML from that page.
I am not entirely sure how to take the forms value (in this case $2) and attach it to the URL.
<html>
<head>
<title>Metar Test</title>
</head>
<body>
<form action="" method="POST">
<p>IACO Code: <input type="text" name="$2" value=""></p>
<input type="submit" name="submit" value="Submit">
</form>
<?php $html=file_get_contents("http://www.metar.mysite.net/metar?id=$2")?>
<?php echo $_POST ["$html"];?>
</body>
</html>
On submit any input from a form with method="POST" will be stored in the $_POST global. You can access it from there and append it to your URL string.
<html>
<head>
<title>Metar Test</title>
</head>
<body>
<form action="" method="POST">
<p>IACO Code: <input type="text" name="iacoCode" value=""></p>
<input type="submit" name="submit" value="Submit">
</form>
<?php
if (isset($_POST["iacoCode"])) {
$html = file_get_contents("http://www.metar.mysite.net/metar?id=" . $_POST["iacoCode"]);
echo $html;
}
?>
</body>
</html>
Using the IF statement to check if it is set will prevent it from loading the URL with no variable.
The way we extract data via php from a form is like below
<html>
<head>
<title>Metar Test</title>
</head>
<body>
<form action="" method="POST">
<p>IACO Code: <input type="text" name="$2" value=""></p>
<input type="submit" name="submit" value="Submit">
</form>
<?php $html=file_get_contents("http://www.metar.mysite.net/metar?id=$_POST['$2']")?>
<?php echo $_POST ["$html"];?>
I hav a Php code. It connects with the server and database, but it does not validate my form data with mysql database table. I hav same exact code which executes, but the following does not execute.........

$upass = $_POST['loginPass'];
$res=mysql_query("SELECT * FROM authen WHERE name='$name'");
$row=mysql_fetch_array($res);
if($row['passwrd']==$upass)
{
$_SESSION['user'] = $row['user_id'];
header("Location: welcome.html");
}
else

isset returns boolean
your code should be
if(isset($_SESSION['user']) && $_SESSION['user'] != "")
{
header("Location: welcome.html");
exit;
}
Or
if(!empty($_SESSION['user']))
{
header("Location: welcome.html");
exit;
}
Do following changes in your first code
if(isset($_SESSION['user']) && !empty($_SESSION['user']))
{
header("Location: welcome.html");
}
hope this helps!!,please comment for further queries
When ever I use this piece of PHP, it makes the webpage blank (white) and does not show anything. Here is my code:
<?php
if(isset($_POST['submit'])){
//
$user = $_POST['username'];
$pwrd = $_POST['pwrd'];
//include database connection
include('../includes/db_connect.php');
if(empty($user) || empty($pwrd)){
echo 'Missing information';
}
?>

</head>
<body>
<div id="container">
<form action="Login.php" mthod="post">
<p>
<label>Username</label><input type="text" name="username" />
</p>
<p>
<label>Password</label><input type="password" name="pwrd" />
</p>
<input type="submit" name="submit" value="logIn" />
</form>
</div>
</body>
</html>
After testing different pieces of the PHP code, I have noticed only this code make the page blank
if(empty($user) || empty($pwrd)){
echo 'Missing information';
}
?>
Is this possibly something to do with Apache, or is there something wrong with my PHP?
There are following problem:-
your first if bracket is not closed. So closed it.
your form method is not correct. Spelling mistake:-
So the correct code is here :-
<?php
if(isset($_POST['submit'])){
//
$user = $_POST['username'];
$pwrd = $_POST['pwrd'];
//include database connection
include('../includes/db_connect.php');
if(empty($user) || empty($pwrd)){
echo 'Missing information';
}
}// missing
?>

</p>
<input type="submit" name="submit" value="logIn" />
</form>
</div>

Output:- before submit :- http://prntscr.com/74xhb7
After submit :- http://prntscr.com/74xhmm
Note:- the bracket that i said you to close you can close it based on your convinence. Thanks.
Also don't panic with error you seen in second screenshot. It's because i am not having included files at my end.
I do apologise in advance for my lack of knowledge in PHP and HTML. I have scoured the internet for 3/4 days trying to create what is probably a simple system. I need the user to enter a digit before the next page is loaded. I have an IF statement on my page.
1.php
<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title></title>
<link href="css/style.css" rel="stylesheet" type="text/css" />
<link href="css/reset.css" rel="stylesheet" type="text/css" />
<div id="container">
<div id="authorise">
<form action="2.php" method="post">
<!--Product Comment Box--><br>
<p>Please enter your 4<br> digit authorisation code:<br> <br>
<input type="text" name="digits" />
<input type="submit" name="submit" />
</form>
</div>
</div>
2.php
<?php
if ($_POST['digits'] === '210392')
{echo 'https://www.facebook.com/'
?>
But I need a form first which the user would input the code '210392' and press submit. Then the if statement can take place. I know how to do a form but dont know how to assign that form a variable name 'digits'. All help is appreciated.
A basic form:
<form action="your_file.php" method="post">
<input type="text" name="digits" />
<input type="submit" name="submit" />
</form>
Then in your_file.php:
<?php
if ($_POST['digits'] === '210392') {
// etc.
$_POST is a superglobal array that has all data POSTed to your script. digits in this case is an index in that array. It comes from the name of the input field.
<form action="check.php" method="POST">
<input type="text" name="digits" />
<input type="submit" value="click here" />
</form>
//in check.php
if (isset($_POST['digits']) and $_POST['digits'] == 12345){
header("Location: http://google.com");
}
else {
echo " error !!";
}
study html from w3school
http://www.w3schools.com/html/html_forms.asp
and php
http://www.w3schools.com/PhP/php_forms.asp
<form action="https://scm-intranet.tees.ac.uk/users/l1071039/bobbin/admin.php" method="post">
Password : <input type="password" name="pwd" />
<input type="submit" name="send">
</form>
// admin.php
<?php
if( isset($_POST['pwd']) ){
$pwd = $_POST['pwd'];
}
?>
You first need to create an input with the very important name attribute which you'll use later.
<form method="post">
<input type="password" name="mypassword" />
<button type="submit">Go</button>
</form>
PHP:
//Post method access with $_POST variable:
if ($_POST['mypassword'] == 'my-password') { //Oh, you should probably use SSH and hash the password
//Hooray!
}
Instead of echo, use header.
<?php
if ($_POST['digits'] === '210392')
{
header (loaction:https://www.facebook.com/);
}
?>
