Editing text files in a directory with PHP - php

Question

I've got a script which lists all the txt files that I have in a directory. I've put a hyperlink each of the results that comes up and I want to the redirect to a simple editor which I have the code for.
This is the code for listing the files in the directory;
<?php
//Open directory
$dir = dir("content");
//List files in directory
while (($file = $dir->read()) !== false){
//Make sure it's a .txt file
if(strlen($file) < 5 || substr($file, -4) != '.txt')
continue;
echo "Page: <a href='content/" .$file. "'>" . $file . "</a><br />";
}
$dir->close();
?>
And the code to edit the file:
<?
if($_POST['Submit']){
$open = fopen("content/body.txt","w+");
$text = $_POST['update'];
fwrite($open, $text);
fclose($open);
echo "File updated.<br />";
echo "File:<br />";
$file = file("content/body.txt");
foreach($file as $text) {
echo $text."<br />";
}
}else{
$file = file("content/body.txt");
echo "<form action=\"".$PHP_SELF."\" method=\"post\">";
echo "<textarea Name=\"update\" cols=\"50\" rows=\"10\">";
foreach($file as $text) {
echo $text;
}
echo "</textarea>";
echo "<input name=\"Submit\" type=\"submit\" value=\"Update\" />\n
</form>";
}
?>
What's the best way to try and do this?
Thanks in advance.

Answer 1

I think you mean this:
in directory list use this:
echo "Page: <a href='editor_script.php?filename=".$file."'>".$file."</a><br/>";
in your editor script use this:
$open = fopen("content/".$_GET['filename'].".txt","w+");
$file = file("content/".$_GET['filename'].".txt");
I' not sure but maybe you have to remove action from form
echo '<form method="post">';
or use url with $_GET['filename']
echo '<form action="editor_script.php?filename='.$_GET['filename'].'" method="post">';
maybe this works too but I'm not sure
echo '<form action="?filename='.$_GET['filename'].'" method="post">';
