php rawurldecode from javascripts' escape()

[swayze]

Hi,

I'm sending some vars to php from javascript. These vars contain
special chars (like "&" ,",")and also turkish characters. Therefore
I'm using javascripts escape() function to be able to send them
properly. My problem is on the php side. I am using rawurldecode to
convert them back. However, Turkish characters like "I" (capital "I"
with a dot on top) for example still stay encoded as "%u0130".

My page is setup to handle turkish chars and if sent from a database,
display properly. I've googled for an answer and cant find anything.

I've also tried looking at base64 encoding from javascripts' end, to
again decode using base64Decode from php, but nothing seems to work
right.

Does anyone have any sugestions?

Thanks in advance,

Swayze

the doc for rawurldecode() says it decodes percent-encodings, but since
'%u0130' isn't a percent-encoding rawurldecode() doesn't decode it. to my
knowledge there isn't a (PHP) function which decodes your encodings.

encoded as UTF-8 and percent-encoded, as RFC3986 prescribes, 'Ä°' (U+0130)
is represented in URIs as <%C4%B0>. rawurldecode('%C4%B0') here gives me
the letter 'Ä°'.

Try using encodeURIComponent() instead of escape(). The function won't
help you though if you're not using UTF-8.

Instead of dealing with encoding issues manually, I would just create a
hidden form on the fly, fill it in, and submit it.

thanks for the replies. I'll try using encodeURIComponent() and hope
for the best. However, if this does not solve my problem, this form on
the fly, what did you have in mind? (Please bear with me. I'm originaly
a .net programmer :-S )

Let me explain my situation:

Right now I'm using iframes. a left and a right frame.
The left frame accesses the db, uses a web service, displays some
stuff, user interacts with the stuff, reaccesses db, web service ect...
at the end I'm changing, with javascript, the location of the right
frame with something like "parent.RIGHT.location =
'right.php?somevar='+might_have_turk_chars" in order to refresh the
contents. I could just send the right frame some numbers, but the with
all the intensive (and also redundant because the left frame has
already done all of it) webservice and db accesses, the delay can be
rather long. I'm just want to send the data to the right frame to be
appended to the existing data. I've considered updating the right frame
only using javascript, but found that building complex table structures
only using javascript and DOM with tds able to respond to javascript
events a little too challenging.

thaks again,

Well, you would have a form with a hidden fields. Set the target of the
form to the frame you want, set the fields to the correct values, then
call submit() to send it. If the method is GET, then it's equivalent to
doing a location = <url>.

It's not that hard really. The trick is to not try to construct the
page programmatically. Instead, build the HTML of the page as through
you'd on the server side, then do document.open(),
document.write(html), and document.close().
