Getting And Recording A Portion Of The Address Bar Similar to AIM subprofiles features

[snlildude87 0]

Does anyone know how to get a portion of the URL, record it somewhere, and display it later? For example, for something like index.php?name=blah, "blah" would be taken out, recorded, and displayed wherever you want it to.That was a terrible explanation, but imagine those AIM subprofiles where each time a user visits, it remembers who you are and how many times you've visited.Thank you in advance!

i used to know how to do that. i know it would end up being $blah and you take the value from that

If the URL was "myfile.php" and they typed "myfile.php?hello=yes" then in the PHP code you do this:

<?php$hello = $_GET['hello'];echo "hello = " . $hello;?>

And the output will be "hello = yes"

OOO!! I'd have to try that sometime.Now, how would you store $hello so you can use it some other time?

If you mean a file, you can do this:

<?php$hello = $_GET['hello'];$file = "info.txt";$handle = fopen($file, 'a'); //Says to open file (or create file) for writing and starts the pointer at the endif(!fwrite($handle,$hello)) //If it can't write{        echo "Could not save information";}else{        echo "Information saved!";}fclose($handle); //Closes file connection?>

It turns out this is not simple as it seems - not for me, at least.

 

This is what I did:

1. Created a blank info.txt file

2. Created a blah.php file (I chose a random name)

3. Copied your code above to blah.php

4. Saved blah.php

5. Uploaded info.txt to my public_html/www folder

6. Uploaded blah.php to my public_html/www folder

7. Changed info.txt's and blah.php's permissions to 777 - just in case

8. Went to sang.trap17.com/blah.php&hello=yes

9. The browser redirected me to my custom 404 error page

 

Is there a step I'm missing in this seemingly easy process because my PHP knowledge is severly limited?

 

Please post a reply. Thank you!

Sorry, didn't see this. When you're putting a variable in the address bar, the first variable has to be after a question mark, not an ampersand. Each subsequent variable is after an ampersand. Like this:

 

site.trap17.com/blah.php?hello=yes&goodbye=no&sixtimesnine=42

Bee! I got the page to work...all by myself! No offense to you of course.

I went to the library and checked out a book called Sams Teach Yourself PHP4 in 24 Hours. There is a section in there on how to read and write files, so I used their examples as a guide for my own code. Of course, I used your code as a template. Here is the final code that works:

<?php$hello = $_GET["name"];$file = "info.txt";$handle = fopen($file, "a"); //Says to open file (or create file) for writing and starts the pointer at the endfwrite($handle, $hello); //takes whatever is in the address bar and append to info.txtfwrite($handle, ";\n"); //adds a newlinefclose($handle); //Closes file connection?>

I created a info.txt and placed it in the same directory as my blah.php file.

Aren't you proud of me? I have barely no knowledge of PHP whatsoever! Man, I'm excited!

Some of the first things I did were with fwrite, it's a pretty neat command. Maybe soon you'll be coding a forum with a flat file database like me =O I gave up on that though when I came to Xisto, becausee mySQL is a lot easier.

Try looking into the parse_url() function - it allows you to disassemble the URI, after which you could, for example, split() it. For example:

$purl = parse_url($url);$query = split('=',$purl['query']);

Try looking at the $_SERVER variable, namedly the REQUEST_URI index.
