Regards, Tim I would use an iframe for this.Didn't test following code, but shoudl work though. iframe name=imgupload/iframe form action=upload.php method=post target=imgupload enctype=multipart/form-data input type=fileinput type=submit value=upload/form and now just make sure that your upload.php script doesn't return anything, or it will be displayed inside the iframe :) If you want to know when upload is done, you should check that through AJAX. you could give the upload an unique number, and store the results of the upload in a database for example, then request that id once in 10 seconds lets say, and when it's done it will return something useful :) Tijnema -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Saving css state in javascript and passing to php via form submit
The weather in here gets stormy easily i see :D
Anyways thanks Richard, that's the kind of idea i was orginally looking for,
before opting for the ajax way, which is only going to optimize my
application more and give me more flexibility in doing what i need.
Have looked up javascript and DOM and now understand how to dynamically
create content from javascript that can later be interpreted by a php form.
In any case everyones input was great, got a lot of ideas out of it.
Thanks all ;)
P.S. Sorry for the delicately on/off topic, was inbetween languages here,
and since i'm more familiar with your input i oppted for this list ;)

So now in the PHP part, to force this at least nominally
on-topic, you have a nice array in $_POST['styles'] with an
index by div in order, that you'd process like any $_POST
value which is an array:
if (isset($_POST['styles']) is_array($_POST['styles'])){
foreach($_POST['styles'] as $d = $style){
//do something with div's $style, indexed by $d
}
}
You could presumably get each div's id with div.id or
somesuch, and use that instead of 'd' above.

It's which are there more of? :-) In other words, if you have 100 $40,000 Sun servers, and you have two options: Throw some PHP on them all, to process this stuff in 0.03 seconds Throw some JS out, and let the client side process it in 0.06 seconds Note that you probably have zillions of visitors with over-powered desktop machines, for the most part. Which is going to make your overloaded servers seem faster? Not that I've ever done this, mind you, but I suspect that it's another case where a raw benchmark isn't really applicable in the Real World, for most cases where you'd even want to benchmark it.

[PHP] Saving css state in javascript and passing to php via form submit
Hello all, I have a little dilemna here: I am using php/css/mysql to generate a hierarchical table of categories and sub-categories and sub-sub.. Etc.. A screenshot can be found here: http://www.internet46.fr/mehim/screenshot.jpg Now i'm also using javascript to hide show blocks of divs to hide/show sub categories.. Typical.. My issue is on page reload, i have a form on the same page, when a category is clicked, the categorie info displays and you can update the info through this form (table and form on same page). My issue comes when i post the data, the page comes back and my category tree folds up which is normal because all divs are set to display:none;. I have managed to pass a post/get called lastclicked that gets the nodepath of that element and combined with php to generate javascript that will unfold the tree and highlight the last clicked element... I would like to go one step further and save the entire state of the tree, say several parent categories are unfolded and i click a subcategorie to display my form, i want that entire state un unfolded categories to be displayed not just the clicked category, of course i can get this state and save it in a javascript array, but my issue is when i post my form how do i pass that state data generated by javascript back to the page, to be able to unfold the tree in the state it was previously?

Cookies are nearly the same as sessions, i found this article (with examples) that goes about parsing cookies from javascript. So you could also do it with cookies. http://www.javascriptkit.com/javatutors/cookie2.shtml Tijnema ps. Maybe you could also use AJAX instead of submitting forms the whole time. In the next version of my framework i would like to, i still havent quite understood the whole concept, not enough research yet, but yes i'll be doing that next ;) (you know deadlines, can't sit and read docs all day etc.. Although i'd rather!) ;) Regards, Tim Really, it's not that hard to use AJAX. You might want to look at www.tizag.com, there it is really easy explained. It's nothing more then making new request to scripts inside javascript. Nice tutorial thanks for that, i'll look it up, maybe intergrate it right away, would really make my day if i could :)) Regards, Tim It's not too hard, but if you already did a lot of work on the form processing, you prefer not to write it all over again i think ;) Tijnema -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Saving css state in javascript and passing to php via form submit
I think you want to use sessions for this :) Ok, i can put the data in the session variable, but i can only get the current state through javascript ie:onsubmit=getstate(); which would get the id's of the blocks that are set to display:block; But in getstate() how do i pass that to php to set that session variable? You could use AJAX to get things from/to PHP, but why should you? You can use session within javascript too i believe. Hmm javascript setting server-side session data?? Sounds weird, but i'll look into it.. server-side session data? i never heard of server-side sessions... AFAIK they are send in the HTTP headers from and to the server. Cookies are nearly the same as sessions, i found this article (with examples) that goes about parsing cookies from javascript. So you could also do it with cookies. http://www.javascriptkit.com/javatutors/cookie2.shtml Ermmm... Isn't $_SESSION a superglobal available only during script execution? Yes it sets a session_id in a cookie to which is sent to the server to identifie the client, but to my knowledge $_SESSION['my_var'] = 'some_data'; is stored server side and set only through a server side script... Now storing data in cookies is client-side, that i agree.. Am i confused or are you confusing me? :P Tijnema ps. Maybe you could also use AJAX instead of submitting forms the whole time.

RE: [PHP] Saving css state in javascript and passing to php via form submit
It's not too hard, but if you already did a lot of work on the form processing, you prefer not to write it all over again i think ;) Actually thanx, that solves my problem if i process my forms/table clicks the ajax way i wont have to reload the page and that takes care of storing the current state :P Regards, Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
