self submited form problem, sorting, cleaning and array...

[Peuplarchie]

Good day to you all,

         

Here I am again with another question regarding a listing and creating file.

This time I would like to 4 things;

 

  - Clean my code, I clean the list and display only the txt file, but I do it 2 time same for where I display it, I'm sure there is a better way..?

 

- Sort last added message on top.

 

- When I add text, the page does not refresh and show what I just enter, I have to add another text to see it, on and on...

 

- Could I get the result of the listing into an array ?

 

 

Here is my code:

 

<?php

//Receive post 
if(isset($_POST['Submit'])){

// list only txt file 
$extensions = array('txt');
$thelist = "";
if ($handle = opendir('.')) {
   while (false !== ($file = readdir($handle)))
      {
          $ext = strtolower(end(explode('.', $file)));
       
          if (in_array($ext, $extensions) AND $file != "." AND $file != "..")
      {
              $thelist .= '<table border=\"1\" align=\"center\"><tr><td width=\"500\"><a href="'.$file.'">'.$file.'</a></td></tr>';
              $contents = file($file);
              $string = implode($contents);
              $thelist .= '<tr><td>'.$string.'</td></tr></table><br/>';
            
          }
       }
  closedir($handle);
  }


//Show the form
echo "<form action=\"\" method=\"post\">";
echo "<textarea Name=\"update\" cols=\"50\" rows=\"10\">";
echo "</textarea>";
echo "<input name=\"Submit\" type=\"submit\" value=\"Update\" />\n
</form>";

//Show the list
echo "<P>List of files:</p>";
echo "<P>".$thelist."</p>";





// Declare Variables
$text = $_POST['update'];
$your_data = $text;



// Open the file and erase the contents if any
$fp = fopen(date('Y')."-".date('m')."-".date('d')."-".date('G')."-".date('i')."-".date('s').".txt", "w");

// Write the data to the file
fwrite($fp, $your_data);

// Close the file
fclose($fp);

// Confirm saved !
echo "File updated.<br />"; 




//else, if you are not receiving a post...
}else{


// list only txt file 
$extensions = array('txt', 'ou');
$thelist = "";
if ($handle = opendir('.')) {
   while (false !== ($file = readdir($handle)))
      {
          $ext = strtolower(end(explode('.', $file)));
       
          if (in_array($ext, $extensions) AND $file != "." AND $file != "..")
      {
              $thelist .= '<table border=\"1\" align=\"center\"><tr><td width=\"500\"><a href="'.$file.'">'.$file.'</a></td></tr>';
              $contents = file($file);
              $string = implode($contents);
              $thelist .= '<tr><td>'.$string.'</td></tr></table><br/>';
            
          }
       }
  closedir($handle);
  }


//Show the form
echo "<form action=\"\" method=\"post\">";
echo "<textarea Name=\"update\" cols=\"50\" rows=\"10\">";
echo "</textarea>";
echo "<input name=\"Submit\" type=\"submit\" value=\"Update\" />\n
</form>";

//Show the list
echo "<P>List of files:</p>";
echo "<P>".$thelist."</p>";



}
?>

 

 

Thanks for your time !
