In my website there is a form with a simple textarea for people to post comments. The problem is that sometimes I receive information in UTF-8 and sometimes in ISO. Is it possible to control that?
Maybe I am doing something wrong, but is it possible that the browser changes the codification of the data it sends?
If you want to be sure of what character set you are accepting, set it in your form
<form method="post" action="/your/url/" accept-charset="UTF-8">
</form>
You can see all the acceptable character sets here: Character Sets
You can always force UTF-8. Then you can send, receive, and store data in UTF-8 ad cover most human languages without having to change character set.
<meta http-equiv="Content-type" content="text/html; charset=utf-8"/>
But... check before encoding, if string is already UTF-8. Else you double-encode it.
function str_to_utf8 ($string) {
if (mb_detect_encoding($string, 'UTF-8', true) === false) {
$string = utf8_encode($string);
}
return $str;
}
Or use
$string = utf8_encode(utf8_decode($string));
So you do not double-encode a string.
I solved this problem by changing mbstring.http_input = pass in my php.ini file
You could encode the $_POST data into UTF-8 using PHP's utf8_encode function.
Something like:
$_POST['comments'] = utf8_encode( $_POST['comments'] );
