Get the name of a HTML file from a PHP script

Question

I want to somehow check the name of HTML file which has a submit button which goes to 'updatecart.php', in this php file I wanted to do an IF statement such as:

updatecart.php - Pseudo code:

IF(calling HTML file == "book1.html"){

// INSERT BOOK1 DATA INTO DATABASE TABLE (SQL)

}

IF(calling HTML file == "book2.html"){

// INSERT BOOK2 DATA INTO DATABASE TABLE (SQL)

}

etc...

I basically have multiple HTML files which all have a form with action set to action = "updatecart.php" and I want to insert different data into the same database table depending on which page the form was submitted.

So I need to find the name of the HTML page from which the form was submitted.

You can use $_SERVER['HTTP_REFERER'], to get the requesting page, but this is not always completely dependable. A better way to go about this would be to put a hidden input unique to the particular page in that page's form and check that instead.

I think it's better to use an input field hidden with value that you want to check.

Eg:

book1.html

<form action="updatecart.php" method="post">
 <input type="hidden" name="filename" value="book1" />
</form>

book2.html

<form action="updatecart.php" method="post">
 <input type="hidden" name="filename" value="book2" />
</form>

And you can check it by,

<?php

$filename = $_POST['filename'];

if ($filename === 'book1') {
 // INSERT BOOK1 DATA INTO DATABASE TABLE (SQL)
} else if ($filename === 'book2') {
 // INSERT BOOK2 DATA INTO DATABASE TABLE (SQL)
}
?>

Thanks, Is there a reason why you left out method = 'post' in book2.html?

Sry! I forgot to put method = 'post' in book2.html. See the above updated one.

No problem, also the 3 equals === is new to me, I use ==

You can find the difference b/w === and == from here, stackoverflow.com/questions/80646/…
