changing config.php via php page

[ajinkya9]

I think you need to open the file in append mode. See if this works.

                       $string = '<?php  
$l13 = "'. $_POST["l13"]. '"; 

?>'; 
  
$fp = FOPEN("config.php", "a"); 
FWRITE($fp, $string); 
FCLOSE($fp); 
  
} 
  
?> 
  
<form action="" method="post" name="install" id="install"> 
  <p> 
    <input name="l13" type="text" id="l13" value="">  
    l13 text 
</p> 
   <p> 
    <input type="submit" name="Submit" value="Install"> 
  </p> 
</form>

EDIT: I just replaced 'w' with 'a'
I am just guessing. I have no idea if php has an append mode.

The php do have append mode but it is not used for this purpose

------------------------------------------------------

Either use what gavo said

Or Other possible ways:

1.
Show all the values in the "admin/index.php" from php file when the page loads

If you dont want to show specific values, then you can keep it hidden

Then get all the specific values and save the file

2.
Open the file! Get it all contents using whichever mode you prefer
Then make a regex replacement for the current vars with the new vars
Save the new text

Hope it helps
