Hello, I'm new to PHP.

I wanted to know about a specific section of PHP about PHP $_GET.

I am trying to link the index.php to index.php?page=downfile&area=1&file_id=1

The page is about an article with a download button.

Do you guys have any idea to code this?

Thanks in advance.

Are you asking how to retrieve url parameters?

PHP Code:

//index.php?page=downfile&area=1&file_id=1

$page = $_GET['page']; //downfile in this case
$area = $_GET['area']; //1
$file_id = $_GET['file_id']; //1 


Maybe, so what do i do to get the page to load? Like do I have to create file for

index.php?page=downfile&area=1&file_id=1

The file is index.php after thing afterward is the query string.

If you're trying to use index.php for both display the article and file downloads, then link download button to index.php?page=downfile&area=1&file_id=1. In the index.php file check for query parametersat the top, if the correct values are present then let the user download the file, otherwise display the article.

Alright, Im getting some stuff going here. But i wanted to know what to do when i link the page like i have:

<a href=index.php?page=downfile&area=1&file_id=1>Some text</a>

Can u explain to me how to do it step by step? Cause right now its showing nothing right now. Just the same index.

The only way a query string is going to make a difference in the output of your script is if you explicitly code it to do so. Here is a trivial example:

PHP Code:

//index.php
if(isset($_GET['page']))
     echo 'Page: ' . $_GET['page'];
else
     echo 'No Page'; 


Where do I insert that code? On my index.php?

The built-in $_GET function is used to collect values from a form sent with method="get".
Information sent from a form with the GET method is visible to everyone (it will be displayed in the browser's address bar) and has limits on the amount of information to send (max. 100 characters).
Example

<form action="welcome.php" method="get">
Name: <input type="text" name="fname" />
Age: <input type="text" name="age" />
<input type="submit" />
</form>
When the user clicks the "Submit" button, the URL sent to the server could look something like this:
http://www.w3schools.com/welcome.php?fname=Peter&age=37
The "welcome.php" file can now use the $_GET function to collect form data (the names of the form fields will automatically be the keys in the $_GET array):
Welcome <?php echo $_GET["fname"]; ?>.<br />
You are <?php echo $_GET["age"]; ?> years old!
