Simple PHP editor of text files
To read the file:
<?php
$file = "pages/file.txt";
if(isset($_POST))
{
$postedHTML = $_POST['html']; // You want to make this more secure!
file_put_contents($file, $postedHTML);
}
?>
<form action="" method="post">
<?php
$content = file_get_contents($file);
echo "<textarea name='html'>" . htmlspecialchars($content) . "</textarea>";
?>
<input type="submit" value="Edit page" />
</form>
You create a HTML form to edit the text-file's content. In case it get's submitted, you update the text-file (and redirect to the form again to prevent F5/Refresh warnings):
<?php
// configuration
$url = 'http://example.com/backend/editor.php';
$file = '/path/to/txt/file';
// check if form has been submitted
if (isset($_POST['text']))
{
// save the text contents
file_put_contents($file, $_POST['text']);
// redirect to form again
header(sprintf('Location: %s', $url));
printf('<a href="%s">Moved</a>.', htmlspecialchars($url));
exit();
}
// read the textfile
$text = file_get_contents($file);
?>
<!-- HTML form -->
<form action="" method="post">
<textarea name="text"><?php echo htmlspecialchars($text); ?></textarea>
<input type="submit" />
<input type="reset" />
</form>
