Text & File Editor Lite

[halojoy]

hi

This little text and file editor
will let you edit code in <textarea>
and Save Code into a file.

I have tested script in my system:
WindowsXP, Apache 2.0.55
PHP 5.1.0, magic_quotes_gpc = OFF
It works very well.

I have added some comments
and I think my script is easy to understand.

Would be happy to know any possible bugs.
How script works in other systems, than what I have.
Suggestions for improvements to prevent issues are most welcome.

FileEditorLite-1.0

<?php // FileEditorLite-1.0 by halojoy
set_magic_quotes_runtime(0);

// file to edit
$filename = 'textfile.txt';

if (!is_file($filename)) {
    // if file does not exist, some default code
    $text_code = '<TEXTAREA rows="4" cols="32">
This is some &nbsp; text.
</TEXTAREA>
<?php echo $myname; ?>
This is my code.<br><br />
&lt;/TEXTAREA&gt;

\\\\ "sometin" //
\\n = newline
&amp;lt;/TEXTAREA&gt;

' . "'bravo2'" . '
hejsan!
';
    // create file and save code
    file_put_contents($filename, $text_code);
}else {
    // if file exists, read contents
    $text_code = file_get_contents($filename);
}

// if code is posted from editor, save to file
if (isset($_POST['txarea'])) {
  $text_code=get_magic_quotes_gpc() ? stripslashes($_POST['txarea']):$_POST['txarea'];
  file_put_contents($filename, $text_code);
}

// display code in editor form
$text_display = htmlspecialchars($text_code, ENT_NOQUOTES);
echo 'filename: ' . $filename . "\n";
echo '<form action="" method="POST">' . "\n";
echo '<TEXTAREA rows="24" cols="80" name="txarea">' . "\n";
echo $text_display;
echo '</TEXTAREA>' . "\n";
echo '<p><input type="submit" value="Save Code"></p>' . "\n";
echo '</form>';
?>

Just two suggestions for enhancing functionality (but then it wouldn't be quite so "lite" anymore!). Well, three, but the first one is probably the worst🙂

1. Create/delete files (very hairy to implement webwise - probably not wise)

2. Editing arbitrary files (instead of just "textfile.txt"). Obviously some state identifying the file needs to be maintained - preferably not somewhere the user can get to in order to fiddle it to point to a different file

3. Multiple files on a page.

I will consider some of this, in next version.

This script was mainly intended for use in webareas, where only you have access.
For example for use in your PC if you have personal webserver.
It was assumed you could edit this script and change $filename = 'somefile.xxx'

To update script and add some 'security'
1. add a simple login, restrict folders where files can be saved.
2. add an <input type='text'> for filename
3. I dont think needs to work at more than one file at the time.
......... this is supposed to stay a simple script

thanks for your suggestions

This is a new version: FileEditorLite-1.1

Code is not changed much, but I have made it a bit 'cleaner',
to make it more easy to see how it works.

The only real change is to make sure code is Saved using Unix LF,
by adding this replacement check, in Line 33:

// replace Windows CR+LF with Unix LF ( \r\n with \n )
$text_code = str_replace(chr(13).chr(10), chr(10), $text_code);

Here is full FileEditorLite-1.1

<?php // FileEditorLite-1.1 by halojoy
error_reporting(2047); // E_ALL debug
set_magic_quotes_runtime(0);

// file to edit
$filename = 'mypage.php';

if (isset($_POST['txarea'])) {
  // if code is posted from editor, code = POST
  $text_code=get_magic_quotes_gpc() ? stripslashes($_POST['txarea']):$_POST['txarea'];
}
elseif (is_file($filename)) {
  // else if file exists, code = file contents
  $text_code= file_get_contents($filename);
}else{
  // else file NOT exist, some default code
  $text_code= '<TEXTAREA rows="4" cols="32">
This is some &nbsp; text.
</TEXTAREA>
<?php echo $myname; ?>
This is my code.<br><br />
&lt;/TEXTAREA&gt;

\\\\ "sometin" //
\\n = newline
&amp;lt;/TEXTAREA&gt;

' . "'bravo2'" . '
hejsan!
';
}

// replace Windows CR+LF with Unix LF ( \r\n with \n )
$text_code = str_replace(chr(13).chr(10), chr(10), $text_code);
// save code in file
$save_code = $text_code;
file_put_contents($filename, $save_code);

// display code in editor textarea form
$text_display = htmlspecialchars($save_code, ENT_NOQUOTES);
echo 'filename: ' . $filename . "\n";
echo '<form action="" method="POST">' . "\n";
echo '<TEXTAREA rows="24" cols="80" name="txarea">' . "\n";
echo $text_display;
echo '</TEXTAREA>' . "\n";
echo '<p><input type="submit" value="Save Code"></p>' . "\n";
echo '</form>';
?>

Hi.
I'll change file_put_contents with
fopen etc because of file_put_contents
starts from PHP 5 for a better portability.
Bye.

There will soon not be many using PHP 4 no more.
PHP 5 is mature now. There has been quite many debugged versions.
We should not encourage people to use older versions of PHP.

Two years is a very long time in the computing world.

PHP 5.1.4 Released: 04 May 2006 ( 11th version of PHP 5 )

PHP 5.0.0 * Released: 13 July 2004 ( first PHP 5, two years ago )

Same way we should not write scripts that depend on:
- register_globals ON
- allow php shorttags
....... and a couple of other bad issues that some still like to stick to.

By using modern, developed and stable PHP versions and write for recommended php.ini settings
we are doing everybody and the PHP itself a big favour.
But nobody can force anybody. Only encourage by setting a good example.

It is upto each, if they want to stay with 'old habbits'
or use new practical, powerful and userfriendly functions.
Like the choice here:

<?php

file_put_contents($filename, $save_code);

// or this way

$handle = fopen( $filename, 'wb' );
$fwrite ( $handle, $save_code );
$fclose ( $handle );

?>

Hi there and thanks for this code!!

I have placed both version 1 and 1.1 into this folder. As you can see I am getting some errors and would love your input.

On version 1 (version1.php), the text area seems to call the txt file perfectly but when I click Submit, I get an error. And version 1.1 (called version2.php) gets an error on page load.

They are located here:
http://www.adventurecapital.biz/textedit/

My server is FreeBSD with:
PHP Version 4.4.2
PHP API 20020918
PHP Extension 20020429
Zend Extension 20050606
magic_quotes_gpc On On
magic_quotes_runtime Off Off
magic_quotes_sybase Off Off

Many thanks!!!!
Cm

Well, halojoy's script isn't very portable - you must be using PHP 5.

Really? I see loads of people still using PHP4 today (including cougar01). I myself use PHP4 at home, on 3 out of 3 websites I code for, and at work. I don't plan on upgrading any of these instances to PHP5 as far as I can see... sure, maybe I'm limiting myself, but you know what they say about things that aren't broken. (..Don't fix them).

Why not just use an abacus then?

Touché!

I don't want to turn this into a PHP4 vs PHP5 thread, so I'll just end by saying... I personally don't see any benefits (at this time) in upgrading to PHP5. I don't use OOP, and I can live without functions like [man]file_put_contents/man simply because I know how to [man]fopen[/man] a file with a mask of w/w+/a/a+ and [man]fwrite[/man] data to that file, remembering to [man]fclose[/man] the file when I'm done with it. shrug

[Shrike]

I guess it depends on what work you do with PHP. If you want use the features of version 5 to the full you simply can't go back to 4.

Hello again people.
Just went back and tested my Text & File Editor Lite. It was relesed here, in June 2006.
My current setup is PHP 5.2.4 with >>>> php.ini-recommended settings

# Apache 2.2.6 for Windows 32
# .htaccess PHP settings

php_flag short_open_tag OFF
php_flag magic_quotes_gpc OFF
php_flag register_globals OFF
php_value error_reporting 2047

The editor script itself turns OFF:
set_magic_quotes_runtime(0)

I really wasnt expecting such an old and simple 1 file script to work without issues.
1312 bytes, with Unix \n line endings.
But to my surprise 🙂 was no error.
The PHP code I entered was written perfectly into target file.

<?php // FileEditorLite-1.1 by halojoy
// Version released: 03 July 2006
error_reporting(2047); // E_ALL debug
set_magic_quotes_runtime(0);

// file to edit
$filename = 'mypage.php';

I am happy 🙂
I may even start using this for some basic webscripts ( blog, guestbook, lite-cms )
that I am currently writing code for.
Not always we would need such great JAVA based editors like

SPAW Editor PHP Edition v2 - DEMO of a great WYSIWYG web addon Java

Size compare:
SPAW PHP v.2.0.6 (Dec 2007)   1 165 731 bytes
Text & File Editor Lite-1.1       1 312 bytes

.... but of course, like with TinyMCE and FCKEditor, SPAW PHP Editor is in a totally different league.

Still I love my little script.
It is 'my style' of KEEP IT SIMPLE coding.
If you would find any small bugs, I will fix this in next release.

Thanks for anyone testing my script.
And also to Weedpacket, who helped me once and gave me a hint to use:
$text_display = htmlspecialchars($save_code, ENT_NOQUOTES);

Regards 🙂
halojoy - is no pityful killer - havent got the guts
- but gets much more pleasure to Write Killer Scripts in PHP 5
You do not need a bunch of B-52 bombers Aeroplanes

to kill a few foreign members of one family or some youngsters in some schools.
It is often enough to fire your handgun or your riffle a few times.
Until you get the result .... you desire.

[laserlight]

Instead of:

error_reporting(2047); // E_ALL debug

Just write:

error_reporting(E_ALL);

The comment is inaccurate anyway since 2047 is not E_ALL but a combination of all the error reporting flags except E_ALL, E_STRICT and E_RECOVERABLE_ERROR.

Also, note that magic_quotes_runtime is deprecated.

Bye.

This is no longer an issue.
Even most Free webhosts, support php 5.

Lies hier weiter: http://gophp5.org/sites/gophp5.org/files/gophp5_logo.png

Question 1:
-- is there anything I could add to my code .. for improvement?
Without making my Text Editor too bloated.
Like to keep it very, very Lightweight Easy and Secure 🙂

That was one huge bump. Anyways halojoy, you are right. Most do support PHP5.
