If anyone can help me to hide the block until a user fail login in or something please :)
First, you have to put your "session_start()" in the first line of your code file.
Second, Php is the server language. So, it will be excute before any others statics language.
In the footer, put something like this (i presume you have jQuery)
$('.alert').hide(); //hide on load page
Put your HTML normaly and in the bottom, make your login check.
If the check is in error, do this :
$('.alert').show();
And that's it.
If your question is "How to show HTML/JS in PHP?", do this :
<?php echo "$('.alert').show();"?>;
in a JS block and "document ready".

php while loop not printing contents of an array horizontally in bootstrap
I am using a while loop in PHP to extract data for some items and print each query like a separate card in the same row as in a shopping cart. Bootstrap seems to print them vertically in separate rows. Expected layout
code

<link rel="stylesheet" href="cart.css"> </head> <body>
<div class="container">
<?php
$connect = mysqli_connect('localhost','root','','cart');
$query = 'SELECT * FROM products ORDER BY id ASC';
$result = mysqli_query($connect, $query);
if (mysqli_num_rows($result)>0) {
while($product = mysqli_fetch_assoc($result)){
?>
<div class="col-sm-4 col-md-3">
<form method="post" class="" action="index.html">

</div>
</form>
</div>
<?php

}
?>
</div>

</html>
I have tried using class="row-fluid" before the start of the loop or even the .product but it doesn't help.
Actual output in normal screen or developer tool
To allow for the products to be shown in 'rows' (horizontally), you need to add a <div class="row"> to your HTML code. I've banged together a small demo, that shows the basic idea (and the use of HEREDOC which allows for (IMHO) cleaner separation of HTML and PHP code).
Function renderProduct() is invoked through a foreach() loop on a dummy product range stored in array $products to imitate your database while loop.
The gist:
<?php
function renderProduct($product = 'n/a') {
$htmlProduct = <<<HEREDOC
<div class="col-sm-4 col-md-3">
<form method="post" class="" action="index.html">
<div class="products ">
<img src="$product" class="img-fluid" />
<h4 class="text-info">$product</h4>
<h4>INR $product</h4>
<input type="text" name="quantity" class="form-control" value="1" />
<input type="submit" name="add_to_cart" class="btn btn-info" value="Add" />
</div>
</form>
</div>
HEREDOC;
return $htmlProduct;
}
$htmlStart = <<<HEREDOC

how to prevent from going back to login page after logging in
I have developed a website in php. The index.php is a login form. After logging in dashboard.php is coming. But when I press the back button in the browser it is redirecting to the login page. How to prevent it. If there is any solution please tell. Thanks in advance. The codes are given below:

I am not sure if I understand the problem correctly, but what if you add a check at the beginning of the index.php file that would redirect you to the dashboard if you are logged in ? Something like this
// index.php
<?php
session_start();
if (isset($_SESSION['status']) && $_SESSION['status'] === "Active") {
header("location: dashboard.php");
}
?>
<!DOCTYPE html>
<html>
<head>
...
this way, if you click back in the browser, you will still go to index.php, but then you will be redirected to the dashboard again if you are already logged in

It looks like my script in login.php is not working. It just shows the text nothing more.

First thing, do all session check in a single file header.php and include this file in all files.
In header.php, modify following code:
<?php
session_start();
$valid = $_SESSION['valid'];
if(!$valid || $valid ==""){
header("Location:index.php");
}
else {
header("Location: home.php");
}
?>
