code writes to single file, want to write to selected file

[?foru]

The following writes to a single text file, but I would like to change it to write to the selected file (file1, file2...so on) so more than one area can be updated. (only one area edited at a time though)

<?php
$data_file='content.txt';
$changes='';

if(isset($contents)) {
      $archive=fopen($data_file,'r+');
      flock($archive,2);
      ftruncate($archive,0);
      fputs($archive,stripslashes($contents));
      flock($archive,3);
      fclose($archive);
      unset($contents);
     $changes='<span class="iheadline">Changes made!</span>&nbsp;&nbsp;&raquo;&nbsp;&nbsp;<a href="/">View Changes [+]</a><br />';
}

function getfile($filename) {
   $fd = fopen($filename, "rb");
   $content = fread($fd, filesize($filename));
  fclose($fd);
   return $content;
}

$data=getfile($data_file);
?>

The idea scenario would be to have a dropdown box with the files listed so you can select the one you want to edit.

$data_file = array('file1' => 'file1.txt', 'file2' => 'file2.txt', 'file3' => 'file3.txt', 'file34' => 'file4.txt'); 

I changed $data_file to an array but I'm not sure how it would all tie together to write to the selected file.

Select dropdown can possibly look like this.

<SELECT name="data_file">
<OPTION value="file1">edit file1</OPTION>
<OPTION value="file2">edit file2</OPTION>
<OPTION value="file3">edit file3</OPTION>
<OPTION value="file4">edit file4</OPTION>
</SELECT>

Any ideas/help would be appreciated. Thank you.

$selected_files = array ("file1", "file2");


foreach($selected_files as $data_file)
{
   $content = get_file($data_file);
    $archive=fopen($data_file,'r+');
      flock($archive,2);
      ftruncate($archive,0);
      fputs($archive,stripslashes($contents));
      flock($archive,3);
      fclose($archive);
      unset($contents);
     $changes='<span class="iheadline">Changes made!</span>&nbsp;&nbsp;&raquo;&nbsp;&nbsp;<a href="/">View Changes [+]</a><br />'; 
}

Thank you CrazyChop

This seems like a nice short piece of code to make this work.
foreach($selected_files as $data_file)

When you login to edit files it uses the following URL
index.php?status=connected

What might be the best way to determine which file to edit?

index.php?status=connected&selected_files=file1.txt
with something like...

if (isset($_GET['selected_files'])) {
$selected_files = $_GET['selected_files'];
} 

to get the page from the URL? $selected_files already sets the array in your code, so the above may not work. Thank you

Can you try the following? Create files content.txt, file2.txt, file3.txt, file4.txt in a directory and save the following as a php page in the same directory...

(I am not sure that this is what you exactly want to do.. But I haen't tested yet)

<form action = "<?php echo $_SERVER['PHP_SELF']; ?>" method = GET>

<table>
    <tr><td><b>Select a file to edit:</b></td></tr>
    <tr><td>
    <SELECT name="data_file">
      <OPTION value="content.txt">edit file1</OPTION>
      <OPTION value="file2.txt">edit file2</OPTION>
      <OPTION value="file3.txt">edit file3</OPTION>
      <OPTION value="file4.txt">edit file4</OPTION>
     </SELECT>
     </td></tr>
    
    <tr><td>
    <textarea rows = 3 columns = 20 name = "contents" ></textarea>
    </td></tr>
    
    <tr><td><b><input type = "submit" name = "submit" value = "Edit" ></b></td></tr>
    
</table>


</form>



 <?php
  
function getfile($filename) {
   $fd = fopen($filename, "rb");
   $content = fread($fd, filesize($filename));
  fclose($fd);
   return $content;
}



 if(isset($_GET['submit']))
 {
 $data_file = $_GET['data_file'];
 $contents = $_GET['contents'];
 
 
 $archive = fopen($data_file,'r+');
      flock($archive,2);
      ftruncate($archive,0);
      fputs($archive,stripslashes($contents));
      flock($archive,3);
      fclose($archive);
      unset($contents);
     $changes='<span class="iheadline">Changes made!</span>&nbsp;&nbsp;&raquo;&nbsp;&nbsp;<a href="' .  $data_file . '">View Changes [+]</a><br />';
     echo $changes;

 
 $data=getfile($data_file); 
 
 
 }
 
 ?>

Thank you borris83.

This is working somewhat...seems to update the files, but working with it to get the initial content from the selected file that was already there.
