string encoding

[manix]

Hey..

 

I have a form where a user inputs text stuff right and I need to encode it BEFORE sending it to the submit page, and after that I need to decode it and import it into mysql.. What I thought of was to encode it in javascript and then decode in php but after a little googling I found out that php and javascript don't actually have many encoding functions in common and I'm stuck now..

encode or encrypt?

 

It'd be as simple as:

$str = "your users input";
$encode = base64_encode($str);
echo $encode;
echo "<br />";
$decode = base64_decode($str);
echo $decode;

 

base64_encode()

yeah if it was that simple I wouldn't be posting, see that's the problem I don't have $str

 

<textarea id='comment' class='writingarea'></textarea>

		<script type='text/javascript'>
		$.post('usercomments.php', { 
									id: user id here;
                                                                                comment: $('#comment').val()
								},
		function(returned) {
			$('#comments').html(returned).show();
		});
		</script>

use the $_POST you're sending...

$str = $_POST['userinput'];

I need to encode it BEFORE sending it to the submit page

why?

 

edit: you can base64 encode with Javascript as mentioned here... http://stackoverflow.com/questions/246801/how-can-you-encode-to-base64-using-javascript  , then base64_decode() in PHP.

because when I pass cyrillic characters through jquery post ajax they get ruined, and I can't really use get method because of safety reasons (not my call)
