HI,
i'm currently working on some web application and i would like to know
what
is the best way to do what i want.
basically like all application i have a menu and based on selected
item menu
i want to display a page (basically 50 % of this new page is DB
result/grid.
As usual i have 2 divs, one for the menu one for the content of DB to
display.
i would like to know if it's not better to use AJAX to load the
content of
the second div (DB result and other stuff) instead to every time load
a new
page which load menu and content of DB ?
what are your experiences on such thing ?
thx.

Alain:
The only difference the user experiences between having AJAX, or not, is
refreshing the page. If page refresh is not a problem, then don't
complicate your life. On the other hand, if page refresh is annoying, or
not wanted, then AJAX is you're only solution.
But as it has been said before, not all users have javascript turned on
and as such AJAX will not work -- after all, it javascript.
However, there are way to degrade gracefully from a AJAX site to a
normal site. Google
javascript graceful degradation for references.
Please note, going the AJAX route does not make your coding simpler --
it's a different critter. But it does (with help from jQuery et al)
offer exciting new ways to present data.

this is a standard response for me recently; but have you looked in to
using flex 3 to build the clientside?
additionally ajax's main benefit (in my mind) is that it allows you to
pull down/update only the data you need, and not the whole page - often
this means you can skip out a large part of the templating and make the
php server side scripts so much lighter; very beneficial when polling.
Other than that, as everyone has mentioned - it's mainly a cosmetic thing.

yes, flex is flash for developers; the main language is AS3 and it

development wise adobe flex 3 SDK works on linux; afaik flex builder
(the wysiwyg ide for eclipse) doesn't yet.
clientside (the apps you develop) work anywhere flash player 9 does.
a great reason to get in to flex now is that flex 4 will also be
supporting most of the major smartphones so you're app's will work
virtually everywhere (and look nicer + dev time wayyy down).
can you tell I like it? (+it's got native E4X support)

A small clarification as per my understanding -- using AJAX does not limit what should be downloaded -- what needs to be downloaded, needs to be downloaded regardless. However, using AJAX does change how the browser refreshes and cuts down the chatter between the server and client. An AJAX request (GET or POST) is simply done behind the browser's back -- if something needs to be brought forward from the server to the client then it makes no difference if you use AJAX or the standard way. In either case, it requires download time and server contact. If you are not using AJAX, then the browser simply refreshes the entire page with what it has cached and goes to the server for what it hasn't. With AJAX, AJAX simply tells the browser what to refresh and leaves the remainder alone. As I said, using AJAX will cut down on the chatter between the server and client, but that chatter is not reloading everything each time. So, AJAX is not really affecting downloads -- those are determined by the needs of the page and not on the manner of the presentation. Now, one can argue that any contact is downloading and I guess that is technically correct. But I am saying that communication between the server and client is different depending upon what's been cached. It's a bit like my wife calling her sister. If my wife gets the answering service, she leaves a message -- if not they talk. While one can say that a call has been made and received in either case, the amount transmitted is significantly different if her sister answers -- if you get my drift.

[PHP] AJAX and PHP
Hi, i'm playing around with AJAX and PHP to create something like a small desktop application. basically the first step is to log in the system. for that i have a log-in form where users can choose the interface language. here is my problem : when the log-in form runs, it is in English. user can click on some arrow to open another DIV and display all other languages available. a click on a particular flag, will call the PHP page where the log-in form (login field + password field) are stored with dynamic language interface. however, i make no sense for the title of this form to call a PHP page where will be just 1 dynamic text (changing on flag choice). so if you understand well, i have 2 divs (1 for form title, 1 for log-in form itself). and i load thanks AJAX php code into divs. my problem is that i do not want to write a PHP page just for 1 label... it makes sense for a complete form but not for a simple text line or label. So how can i do that without refreshing page. using AJAX and PHP only ? i guess you already faced such situation so i would really appreciate your help. thanks a lot, -- Alain Windows XP SP2 PostgreSQL 8.2.4 / MS SQL server 2005 Apache 2.2.4 PHP 5.2.4 C# 2005-2008
Re: [PHP] AJAX and PHP
Quoting Alain Roger [EMAIL PROTECTED]: Hi, i'm playing around with AJAX and PHP to create something like a small desktop application. basically the first step is to log in the system. for that i have a log-in form where users can choose the interface language. here is my problem : when the log-in form runs, it is in English. user can click on some arrow to open another DIV and display all other languages available. a click on a particular flag, will call the PHP page where the log-in form (login field + password field) are stored with dynamic language interface. however, i make no sense for the title of this form to call a PHP page where will be just 1 dynamic text (changing on flag choice). so if you understand well, i have 2 divs (1 for form title, 1 for log-in form itself). and i load thanks AJAX php code into divs. my problem is that i do not want to write a PHP page just for 1 label... it makes sense for a complete form but not for a simple text line or label. So how can i do that without refreshing page. using AJAX and PHP only ? i guess you already faced such situation so i would really appreciate your help. thanks a lot, -- Alain Making an Ajax request for one little label maybe a bit overkill. As i understand you request the whole form through an Ajax request. And display this to the user? And every language generates a new form? Why not just create the form dynamically with javascript and load the data from PHP. So the form can stay the same for all calls. You just fill it with data depending on the language selected. You can fill the form for instance by sending a JSON encoded object from PHP to javascript. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] AJAX and PHP
you understood right. basically my problem is that the layout avoid it. here is something like my layout : div#0 div#1Lanague (label) : img flag img arrow to show all languages from div#2/div#1 div#2 all flags/div#2 div#3 login field + pwd field + submit button/div#3 /div#0 till now i only use AJAX to refresh the content of div#3 but it does not change the label from div#1 when user selects another language from div#2. if i place the whole form into a PHP i face several questions : - how the ajax will reload this PHP page (reloading itself) in the parent control div#0 ? - when user will click on submit button, where will be loaded the content return of checking if log+pwd are correct ? - how to redirect to another PHP page, when user click on submit button ? the redirection will happen only in the content div, so only in div#0 and not into the browser :-( Al.

Re: [PHP] AJAX and PHP
in fact i meant by redirecting the following thing : - if user wrote a correct pwd and login, the system should redirect [using header(Location ] syntax to launch the application. but if i use such syntax it will be redirected only into the div#0, and not in the browser itslef. is it clearer now ?

It's crystal clear :) I guess you could do it in two ways. Firstly without a redirect. You could just use javascript and CSS to show some sort of error message. Reload the form in the div. And give the user another try to login. If you really want a reload. You have to do it with javascript. You could let PHP send back a status to javascript. And based on that. Either load a div with content. Or do a document.location = ''; Hope it helps.

As noted, that's a javascript question. However your PHP code is
vulnerable to XSS attacks; you should at least encode the output with
htmlspecialchars() so that URLs like
foo.php/scriptalert('hi');/script are safe.
eg. ?php echo htmlspecialchars($_SERVER['PHP_SELF']); ?
