[SOLVED] Flat file and passing data

[Schlo_50]

Hey guys,

 

I am currently working on a project whereby users login to my website (which is working) and then using a form add new links/tabs to their navigation bar (which i need help developing). So for instance if the user had 'home/search engines/favourites' as links on their navigation bar and they wanted to add auction sites as a group title they fill out the form which wants the name of the link and the URL it goes to.

 

So far i can make the form send the link name and URL to my flat file database (usertabs.txt) but i also need the form to once submitted automatically insert the users username before the link and URL to make their new link unique to them. So in the flat file the structure will be:

 

username|Link name|URL

 

The usernames etc are stored in a separate .txt file.

I have this code so far which is the basis for uploading new links to a users navigation bar. $userid is the variable i want to be associated with the user who is logged on.

 

function addtab($name,$link){
if ($_POST['submit'] == "submit")
{
$file_name = "usertabs.txt";
$open_file = fopen($file_name, "a+");
$file_contents= $_SESSION['$userid)'] . '|' . $_POST['name'] . '|' . $_POST['link'] ."\n";
fwrite($open_file, $file_contents);
fclose($open_file);
echo "New Tab successfully uploaded";
}
}

 

This is how i check user existance if this helps?

 

$pfile = fopen("users.txt","r");
    rewind($pfile);

    while (!feof($pfile)) {
        $line = fgets($pfile);
        $tmp = explode(':', $line);
        if ($tmp[0] == $user) {

 

I am really stuck and i just don't know how to make the upload a new link part add the users username if they are logged in.

 

Anyone any suggestions or help?

 

Thanks!

Are your users logged in using sessions? If so, simply store the users username in the $_SESSION array ($_SESSION['username']) and use that.

 

$file_contents= $_SESSION['username'] . '|' . $_POST['name'] . '|' . $_POST['link'] ."\n";

Yeah--->

 

<?php
