I am fairly new at PHP.
Is it possible to post data to a database on visit of a URL?
I want the user to scan a QR code that open up a link that just echo a message. But in the back end the date and time is recorded to a database. How would I do that?
Thanks again
Yes, it is very possible...
yourscript.php
<?php
$somedata=isset($_GET['somedata'])?$_GET['somedata']:null;
$conn=getYourDBConnction();
$sql='INSERT INTO yourTable(datatime,somedata) VALUES(NOW(),?);
$stmt=$conn->prepare($sql);
$stmt->execute(array($somedata));
echo('response');

I have a phpmyadmin database that stores data from a simple form. Now i just have to make a page that shows all the answers nicely. How do i import data from that database to the new page?
Fixed: I learned some simple php and then i was good to go. Sorry for any inconvenience.
you need to write query to fetch data from your database and Display it on another page

Hello I have to create a function which generates a barCode INT25 in php. Any ideas how to do it. The function should generate the image and give back the url where to find it.
Thank you very much
There are many examples, and libraries/classes, that can assist in this. Most of these, when you create the image, you save it instead of discarding. Then you can also post the url, or save it in a database for later use. Some examples are as follows:
