PHP edit file on server? - Inventor - 10-21-2011
Hello,
I am getting a error when I use a post variable to edit a file on the server.
What I want is to enter the name of the file and then edit it.
Here is my code:
First file "editor.php"
PHP Code:
<form action="editpage-2.php" method="post" />
<input type="text" name="page" />
<input type="submit" value="Submit" />
</form>
Second file "editpage-2.php"
PHP Code:
<?php
$firstfile = $_POST['page'];
echo $firstfile; // the file is shown, and is there
$fn = $firstfile;
if (isset($_POST['content']))
{
$content = stripslashes($_POST['content']);
$fp = fopen($fn,"w") or die ("Error opening file in write mode!");
fputs($fp,$content);
fclose($fp) or die ("Error closing file!");
}
?>
<form action="<?php echo $_SERVER["PHP_SELF"] ?>" method="post">
<textarea rows="10" cols="100" name="content"><?php readfile($fn); ?></textarea><br />
<input type="submit" value="Save" VALUE="Refresh">
</form>
The problem is when I hit the save button, it shows this error:
Notice: Undefined index: page in C:\xampp\..\editpage-2.php on line 3
Warning: fopen() [function.fopen]: Filename cannot be empty in C:\xampp...\editpage-2.php on line 11
Error opening file in write mode!
Is there any thing that I missed?
Thank you all,
Inventor

I can seem to find any reference to the "undefined index: page"...
Code:
<form action="<?php echo $_SERVER["PHP_SELF"] ?>" method="post">
<textarea rows="10" cols="100" name="content"><?php readfile($fn); ?></textarea><br />
<input type="submit" value="Save" VALUE="Refresh">
</form>And yet your script tries to locate it...
PHP Code:
$firstfile = $_POST['page'];
Cleared and should work, still not secure though...
Study the script and look at the changes before you just go on copy-pasting...
Code:
<?php
$firstfile = (isset($_POST['page'])) ? $_POST['page'] : ((isset($_GET['page'])) ? $_GET['page'] : '');
echo $firstfile; // the file is shown, and is there
$fn = $firstfile; // totally wasting resources and space: lulz
if (isset($_POST['content']))
{
$content = stripslashes($_POST['content']);
$fp = fopen($fn,"w") or die ("Error opening file in write mode!"); // fopen($firstfile) // remove $fn
fputs($fp,$content);
fclose($fp) or die ("Error closing file!");
}
?>
<form action="<?php echo $_SERVER["PHP_SELF"].'?page={$firstfile}' ?>" method="post">
<input type="text" name="page" value="{$firstfile}" /><br />
<textarea rows="10" cols="100" name="content"><?php readfile($fn); ?></textarea><br />
<input type="submit" value="Save" VALUE="Refresh">
</form>RE: PHP edit file on server? - Inventor - 10-21-2011
It was not a copy paste.
Thank you for helping me!
Edit:
The page is getting the posted variable from another page "editor.php", not from the current page.
$firstfile = $_POST['page']; Is from the post from the editor.php.
RE: PHP edit file on server? - Gaijin - 10-22-2011
You have your editor.php, and then you have the line in code;
PHP Code:
$firstfile = $_POST['page'];
The code I posted works as intended too, and if it's not what you want then read about using sessions and checking $_POST.
