Edit file

e39m5

I got the code to open a file and read it in a file:
<textarea><? readfile($file); ?></textarea>
but how can i save the edits? how can i make my links have the file name to open stored in them, like edit.php&file=file.html, is that right?

thanx in advance,

hello,

can you please post your code for reading the file into your script. It is really simple to just reverse the code that you already have to store the updated information.

You might want to think about security also.. what happens when a user rewrites the file.html to index.html.. you want to ensure the user is not able to rewrite other parts of your site!

thanks,

i already posted my code reading the file, i just need the code for overwriting what is already there instead of just addning to the bottom of the file. this is in a password protected administrator only page, so unless i want to mess up my whole site, well i dont, so there is no unless, 😃

hello,

check out the php manual for the fopen() function..

Also check out Writing PHP - 7: Reading and writing files over at www.codehelp.co.uk

here is a snippet of code

<?
// read temp.php, write tempinclude=1,
// then insert temp.php into final outputfile
// note: not for use on very small, single line files -
// use fgetc() instead

$maxread=filesize("temp.php");

if (!($fout=fopen($outputfile,"w"))) die ("Cannot create output file.");

fwrite($fout,"<?php\n$tempinclude=1;\n?>");

if (!($fp=fopen("temp.php","r"))) die ("Cannot open temporary file.");

$data = fgets($fp,$maxread);
while ((ftell($fp)<$maxread)) {
	fwrite($fout,$data);
	$data = fgets($fp,$maxread);
}

fclose($fp);
fclose($fout);
?

hope this helps,
