Anyone have a good method of grabbing the current page and reading data
from it?
For example:
<?PHP
 // find all form fields for current page
 function FindFormFields( $page ) {
  if( empty( $page ) ) {
   $data = -1;
  } else {
   if( ( $fh = @fopen( $page, "r" ) ) === FALSE ) {
    $data = -1;
   } else {
    while( !feof( $fh ) ) {
     $line = fgets( $fh, 512 );
     if( eregi( "<input type=\"", $line ) ) {
      $data[] = $line;
     }
    }
    fclose( $fh );
   }
  }
  return $data;
 }

 echo FindFormFields( "http://php.net"; );
?>

The above code would output the following:
Array
(
    [0] =>    <input type="text" name="pattern" value="" size="30"
accesskey="s" />

    [1] =>    <input type="image"

)

Now for the problem I am having and a description of what I am trying to
accomplish:

I want to dynamically generate a form and in doing so I would like to
dynamically generate the following javascript features for said page
  - javascript form validation
  - javascript form field focus

The problem is if I call the current page that is being generated such as
<?PHP
echo FindFormFields( "http://"; . $_SERVER['SERVER_NAME'] .
$_SERVER['REQUEST_URI'] );
?>

Not only does it take a helluva long time to load the page but it also
creates a nested array with duplicate values.


I'm not surprised it's taking a while to load in your browser. I think 
you have a serious nested loop issue there. What you're doing is telling 
the PHP engine to load the same page again. When it does that it's going 
to call your function *again* on the same page. Rinse and repeat.

But i don't understand what putting those tags in an array is going to 
accomplish. Perhaps there's a lot more to this, but i'd be inclined to 
set up my validation in a more targetted manner.
