Problem with editing contents

miikha27

I have problem when I try to edit contents of text file in form fields and saving edited result into text file. My edit front page code look like this:

<?php

$handle = fopen("file.txt", "r");

if($handle)
{
while (!feof($handle)) {

$contents = fgets($handle);
$first_token = strtok($contents, '=');
$second_token = strtok('=');

<?php
}
}

fclose($handle);
?>

Code load contents of text file into form fields. But when I try to save contents to text file then my code save only two last form fields but other fields it ignore. How I can save all contents of form fields to text file.

There are some issues in yout code:
- you're starting the form a bunch of times (for every line) and then you're ending it once
- you've got inputs with the same name - so probably the browser assigns the last pair to them. You should name them net[] and ip[]. That allows you to use $POST['net'] and $POST['ip'] as coresponding arrays.
- you're closing file even if it failed to open
- it's easier to use [man]file()[/man] to read files;
- you're not using [ PHP] tags while posting php code in this forum.

<?php
$file = file("file.txt");
if(is_array($file))
{
?>
 <form action="match.php" method="post" enctype='multipart/form-data'>
<?php
 foreach ($file as $contents) {
  $first_token = strtok($contents, '=');
  $second_token = strtok('=');
  // I'd use list($first_token,$second_token) = explode("=",$contents)
?>
  <p><input type="text" name="net[]" value="<?php echo $first_token; ?>"/>
  <p><input type="text" name="ip[]" value="<?php echo $second_token; ?>" />
<?php
 } //foreach
?>
 <p><input type="submit" name="submit" value="Save" /></p>
 </form> 

<?php
}//if
?>
