Edit a file with PHP - php

Question

Ok here is what I have going on.
I am listing the contest of a directory so I can edit and delete files.
The code I am using to do that is below (Other then editing as it does not work).
<?php
$directory = ("enctlfiles/");
$dir = opendir($directory);
$files = array();
while (($file = readdir($dir)) != false) {
$files[] = $file;
}
closedir($dir);
sort($files);
print("<TABLE border=1 cellpadding=5 cellspacing=0 class=whitelinks>\n");
print("<TR><TH>File Name</TH><th>Modified Date</th><th>Entries In File</th><th>Delete | Edit</th></TR>\n");
foreach ($files as $file)
{
if (strpos($file, '.jpg',1)||strpos($file, '.ctl',1) ){
echo "<TR><TD><a href=$directory$file>$file</a></td>";
echo "<td>";
echo date("F d Y H:i:s",filemtime($directory. $file));
echo "<td>";
echo count(file($directory. $file));
echo "<td>";
echo "<a href=enctlfiles/dodelete.php?file=$file>Delete</a> | <a href=enctlfiles/editfile.php?file=$file>Edit</a>";
}
}
?>
That lists all of the files in order in a nice pretty table. The delete function works. The edit one not so much . It is due to me not knowing what I am doing I am sure of it.
Here is the contents of the editfile.php
<form action="edit.php" method="post">
<TEXTAREA NAME="save" COLS=150 ROWS=50 wrap="off">
<?php
$dir = ".";
include($dir. '/' .$_GET['file']);
?>
</textarea>
<P><INPUT TYPE="SUBMIT" VALUE="Update File"><INPUT TYPE="RESET">
</FORM>
That populates the textarea with the file contents when you click on the "Edit" link. I don't know if that is the right way to get the data in there to be able to edit the file.
Here is the contents of the edit.php file:
<?php
//I have tried this but it give me that Unable to open file.
//$org = ($_GET['file']) or exit("Unable to open file!");
//This returns me to the prodsh.php page but does not edit the file.
$org = $_POST['save'] or exit("Unable to open file!");
$copy = $org . date("-m-d-Y-His");
copy($org,$copy);
$f = fopen($org, 'w');
fwrite($f, $_POST['save']);
fclose($f);
header('Location: http://somesite.com/GroveTuckey/itemsetup/prodsh.php');
?>
I think the editfile.php and the edit.php file are jacked up but don't know where.
I am trying to learn this and this site has been very helpful when I get stumped on something so I thank you in advance for the help given.
Also I know the danger of editing files via a webpage. This is not public or on a server that is accessible by the world. Right now I don't want to deal with a database.
I have edited files using the below code:
<form action="doedit.php" method="post">
<TEXTAREA NAME="save" COLS=150 ROWS=50 wrap="off">
<?php
include('somefile.ctl');
?>
</textarea>
<P><INPUT TYPE="SUBMIT" VALUE="Update File"><INPUT TYPE="RESET">
</FORM>
With the contents of doedit.php being:
<?php
$org = 'Somefile.ctl';// This is the name of the file in the form above
$copy = $org . date("-m-d-Y-His");
copy($org,$copy);
$f = fopen('somefile.ctl', 'w');//This is the name of said file also.
fwrite($f, $_POST['save']);
fclose($f);
header('Location: http://somesite.com/GroveTickey/editfile.php');
?>
But since the names of the files can be anything I can't put specific names in the script.
This works great other then having to hardcode file names.

Answer 1

You aren't passing the name of the file back to edit.php. Set the form's action to edit.php?file=<?php echo $_GET['file']; ?>.

Answer 2

El codigo para editar lo hice asi:
---Inicio
<? php
$filename = isset($_GET['file']) ? $_GET['file'] : '';
$directory = ("C:\\Linux\\www\\contenido\\"); // Restrict to this directory...
$fn = $directory . $filename;
if (isset($_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 $_SERVER["PHP_SELF"] ?>" method="post">
<textarea rows="25" cols="100" name="content"><?php readfile($fn); ?></textarea>
<hr />
<input type="submit" value="Guardar">
</form>
back to list
And work great
