I need to make a comment box using a txt file or anything else

  • 0

I need to make a comment box using a txt file or anything else that can be queried passively, without using a database server. As I’m fairly new to PHP programming the first idea was to use a text file. The code in general to accomplish this, as far as I can think of logically would be :

    <html>
<head></head>
<body>
<form method = "post">
<textarea name = "txt" cols = "25" rows = "5">
Place your comment here ...
</textarea><br><br>
<input type = "submit" value = "Submit" onclick = "<?php
    $com = $_POST["txt"];
    $file = fopen("inrg.txt", "a");
    fwrite($file, "<br>");
    for($i=0; $i <= strlen($com) - 1; $i++)
        {
        fwrite($file, $com[$i]);
        if($i % 37 == 0 && $i != 0)
            fwrite($file, "<br/>");
        }
    fwrite($file, "<br>------------------------------------------");
    fclose($file);
?>">
<br>
</form>
<font face = "Times New Roman"><b><p>Textul introdus este: </p></b></font>
<font face = "Comic Sans MS" color = "red" size = "2" >
<?php
$file = fopen("inrg.txt", "r");
echo fread($file, filesize("inrg.txt"));
fclose($file);
?>
</font>
</body>
</html>

Nothing fancy yet, and it does needs some improvements on the esthetics side. The thing is after I submit something in the comment box, it shows properly but if I do reload in the web browser, the last posted comment it’s posted again as many times as I reload the page.
Also if there’s a way with PHP to make the initial “Place your comment here …” disappear

    Here is one way to do it redirecting the page to itself:

    <html>
<head></head>
<body>
<form method="post">
  <textarea name="txt" cols="25" rows="5"></textarea>
  <br><br> <input type="submit" value="Submit" name="submit" />

  <?php
  if ( isset( $_POST[ 'submit' ] ) ) {
    $com  = $_POST[ "txt" ];
    $file = fopen( "inrg.txt", "a" );
    fwrite( $file, "<br>" );
    for ( $i = 0; $i <= strlen( $com ) - 1; $i++ ) {
      fwrite( $file, $com[ $i ] );
      if ( $i % 37 == 0 && $i != 0 ) fwrite( $file, "<br/>" );
    }
    fwrite( $file, "<br>------------------------------------------" );
    fclose( $file );
   echo '<script type="text/javascript">window.location ="";</script>'; // Add here
  }
  ?>

  <br>
</form>
<font face="Times New Roman"><b><p>Textul introdus este: </p></b></font>
<font face="Comic Sans MS" color="red" size="2">
  <?php
  if (file_exists("inrg.txt")) {
  $file = fopen( "inrg.txt", "r" );
  echo fread( $file, filesize( "inrg.txt" ) );
  fclose( $file );
  }
  ?>
</font>
</body>
</html>
