i've been searching google for ages and cannot find anything about this that i can understand. basically what i want to know is what is the basic html/php code to write a forms contents to a .txt or .html file.

I'm assuming you don't have a great understanding of either PHP, or HTML forms. As such, this is a complete example. It will create a file called "input.htm" and fill it with the information from the form. It will erase any existing data within the file as well.

PHP Code:


			
<?php

if(isset($_POST['f_name'])) {

  // Below we start off with some HTML

  $out = "<html>\n<head>\n<title> Stuff from form </title>\n</head>\n";

  

  $out.= "<body bgcolor=\"#FFFFFF\">\n";

  $out.= "<b>Name:</b> ".$_POST['f_name']."<br>\n";

  $out.= "<b>Age:</b> ".$_POST['f_age']."<br>\n";

  $out.= "<b>Hair Colour:</b> ".$_POST['f_hair']."<br>\n";

  $out.= "</body>\n</html>";



  // Create / open the file for "w" (writing)

  $fp = fopen("input.htm","w");



  // Put the contents of $out into the file opened with $fp

  fwrite($out,$fp);



  // close the file

  fclose($fp);

}

?>

Then, just below that, Put this code;

HTML Code:

<html>
<head>
<title> The form </title>
</head>
<body bgcolor="#FFFFFF">

<form method="POST" action="<?php echo $PHP_SELF; ?>">
Your name <input type="text" name="f_name"><br>
Your age<input type="text" name="f_age"><br>
Your hair colour<input type="text" name="f_hair"><br>
<input type="submit" value="save info"><br>
</form>

<a href="input.htm" target="_blank">Read the input.htm file</a>

I took your example and used it, but all I wanted to do was erase a file, an error.log file

Heres what ive broken it down to and it works fine, its just for that one text box that I dont want to show, how do I get rid of that and still keep it working..

when I delete this line the text box is gone but the script no longer erases:

<br><input type="text" name="f_name"><br>

PHP Code:


			
if(isset($_POST['f_name'])) { 
  // Create / open the file for "w" (writing) 
  $fp = fopen("error.log","w"); 
  // erase the file 
  fclose($fp); 
}

HTML Code:

 
<center><form method="POST" action="<?php echo $PHP_SELF; ?>">
<br><input type="text" name="f_name"><br>
<input type="submit" value="Press to Clear Log!">
</form>
<a href="error.log" target="_blank">View error.log in Browser Window</a></center><br>

thanks in advance
