Hello

I have Facebox javascript to output anything in modal window.
I want to display at modal box a form. Form - it is html code.
The form I do generate in the php code - for now just echo
all elements to buffer and then put buffer to variable.
I have a question - what way I can pass this variable with
form to script?
Or may be other solution to pass from php to javascript
a form?

Heh. I was thinking the same thing when I read the question :)

OP, it's hard to understand what you're trying to do ("Facebox
javascript to output anything in modal window" doesn't mean anything at
all to me). Are you trying to set the value of a JS variable from PHP?
If so, all you need is

<script type="text/javascript">
var myHtmlString = "<?= escapeJS($htmlString) ?>";
</script>

You'll have to provide an "escapeJS" function; maybe something like this:

function escapeJS ($str)
{
$str = strtr($str, array(
"\b" => '\b',
"\f" => '\f',
"\n" => '\n',
"\r" => '\r',
"\t" => '\t',
"'" => "\\'",
'"' => '\\"',
"\\" => "\\\\",
));
return str_replace("</", "<\\/", $str);
}

If you're using XHTML, you'll also need to escape the XML special
characters, or use a CDATA block.

Another possibility would be to fetch the HTML content with an
XMLHttpRequest.

If that doesn't answer your question, you'll need to provide some
details. In the meantime, I'm sure somebody will find a problem with my
escapeJS() example, and we'll have a nice discussion about that ;-)

I have html in the PHP variable like:
$face_form = '<h3>Leave a Reply</h3><div class="cancel-comment-reply">';

I want pass this variable by onclick to javascript. Like:
echo '<a href="#modalcomment" onlick="modalcommenttask(' . $face_form .
');">' . 'TEXT' . '</a>';

But I can't pass variable since it have double quotes:
onlick="modalcommenttask(h3>Leave a Reply</h3><div class="

What the solution to pass html form from PHP to javascript function.

But... I just explained how! You need to escape the string contents, and
you (obviously) need to wrap the string in quotes (double or single),
like you do in PHP.

Since you're putting all of this inside an HTML attribute, so you'll
have to escape the HTML special characters as well (including quotes).
The htmlspecialchars() function does that for you.

Anyway, having escaped HTML in an HTML attribute... brrr. Are you sure
this is the best way to do it?
