    Change username
    « on: March 01, 2006, 02:00:04 AM »
    As you have followed a few posts of me you would see that I'm writing a login-script. First of all I would thank robpomeroy for all the help I had from him. (secuirity for the script, and help with pictures in the script!). Now I have a new question. I would like that my users can change there name (not  login name, just there name).

    On all the pages there name is displayed by this code:
    Code: [Select]
    include("username.txt");?>

    and in the txt file this is written:
    Code: [Select]
    <?php echo'username'?>

    Now I would like to have that it is possible to change this name. So I would like to have a textform where you can type your name and a submit button and than your name is changed (in the text file). Does anyone knows how to do this

    Is there a chance you can keep your users' details in a database (e.g. MySQL)?  Your answer will make a big difference to my suggested solution.

      No I don't have mysql on my server, not even msql. But the thing I actually want is: that the name you typed in the box, wil be changed in the textfile. Example if you type Blackberry and then submit, that the textfile <?php echo'username'?>, will be changed to <?php echo'blackberry'?>

      something like...

      Code: [Select]
      <?
      rename("/dir/username.txt", "/dir/newNAME.txt");
      $read = file_get_contents(username.txt);
      $replace = str_replace("username", "newName", "$read");
      $fp = fopen("username.txt", "w");
      fputs($fp, $replace);
      fclose($fp);
      ?>

      if you dont understand a command ther explained on php.net or i'll be happy to fit it in your code if you posted it?

      http://something like...

      [code]
      <?
      rename("/dir/username.txt", "/dir/newNAME.txt");
      $read = file_get_contents(username.txt);
      $replace = str_replace("username", "newName", "$read");
      $fp = fopen("username.txt", "w");
      fputs($fp, $replace);
      fclose($fp);
      ?>
      [/code]

        fclose($fp);
        ?>

        thanx for the code... But it isn't exactly what I want to. I want that de username.txt file stays with the same name, only the text within it should change. This is my submit form

        <body>

        <form name="post" method="post" action="config.php">

        <head>

        <title></title>

        </head>


        &nbsp;

        <p>&nbsp;</p>

        <p><font face="Arial" color="#000080">Type your new name </font></p>

        <p><font face="Arial" size="2"> <input type="text" name="name" value="" maxlength="90" size= 22 tabindex="1">


        <input type="submit" name="Submit" value="Toevoegen" tabindex="1">

        </font>

        </form>

        </body>

        then simply take away the part that changes the text file,
        config.php
        Code: [Select]
        <?

        $nename = $_POST['name']
        $read = file_get_contents(username.txt);
        $replace = str_replace("username", "$nename", "$read");
        $fp = fopen("username.txt", "w");
        fputs($fp, $replace);
        fclose($fp);
        ?>

          Thank you for the scrip, but when I install it, it doesn't work....  :(. I don't know why but the file config.php gives just a white screen. Btw I think your script only change the word USERNAME if it is in the textfile. But what if I want to change my name again after username: example to blackberry, how do I change that then....

          It only changes the word username to a new word, and it appers blank because it dosent desply any html. Presumabley you already no the name in the textfile if ther logged in?
          if not i have some code i created and you can use it to find out the username in the file.
          At the moment i'm at collage i'll post it when i get home

            Itstead of the text file containg echo (name) just put the name in it.
            eg "Fred"

            once done that just get the context of that file and echo it.
            Code: [Select]
            <?
            $read = file_get_contents(username.txt);
            echo ("$read");
            ?>
            config.php
            Code: [Select]
            <?

            $newname = $_POST['name']
            $read = file_get_contents(username.txt);
            $replace = str_replace("$read", "$nename", "$read");
            $fp = fopen("username.txt", "w");
            fputs($fp, $replace);
            fclose($fp);
            ?>

              I don't think this will work the way you want it to, blackberry.  The contents of the username.txt file will be served up to all visitors to your web site.  So if one person changes it, every other person seeing the next page will be faced with the wrong username.

              How about instead using a cookie stored on the user's PC?  No need to change any file on your server then.  Their usernames get stored as a cookie on their PC - you can check for the presence of it and respond accordingly.

              What do you think?

              Incidentally, when you were seeing a white page aboe, that may also have been because there was an error in the php - a missing semicolon at the end of the first line.  If display_errors is set to off in php.ini, then you will not get a report - just a blank page.
