[PHP] Re: PHP, Javascript, and Forms
Hello, on 05/30/2006 11:03 PM Beauford said the following: I have a form with about 20 fields in it and have two drop down menus in which the second one changes depending on the previous one. This is done with a javascript which reloads the page. The problem with this is that everything the user has put in so far gets erased when the page reloads. I am using PHP sessions, but at this point these fields are not saved yet. Is there a way to do this using sessions, or some other PHP function. All the javascript I've looked at reloads the page. This also screws up my validation routines. You may want to try this forms generation and validation class. It provides means to do exactly what you want. It comes with several plug-ins that simplify the implementation of controls like you want. There is one plug-in that can link 2 or more select inputs, on which one switches its group of options when another changes the currently selected value. The new group of options can be loaded from a static array or dynamically connecting to the server via AJAX and executing some task that gets the new set options depending on the new linked select value. It comes also with several variants of the plugin that query databases to retrieve the new sets of options. Here is a screenshot of a form using the static array version: http://www.phpclasses.org/browse/view/html/file/9879/name/test_linked_select_page.html There is also a more generic plug-in form submitting the form using AJAX. This means that you can submit the form without reloading the page. In response you can tell the class to make the current browser page be updated arbitrarily. There is now even a plug-in to integrate with Google Maps, but that is anothe story: The class and all plug-ins are available here. See the dependent classes too for more third party plug-ins: http://www.phpclasses.org/formsgeneration -- Regards, Manuel Lemos Metastorage - Data object relational mapping layer generator http://www.metastorage.net/ PHP Classes - Free ready to use OOP components written in PHP http://www.phpclasses.org/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Where is this being called from? Checkboxes don't have a length...
if u declare is like name=list37 doesnt PHP get that as an array
even though it doesnt have the square brackets?
No, you need the square brackets to return an array of values.
Otherwise you'll only get the first one.

Could you not use an id for the object as well as a name?

Hi,
I'm trying to integrate some JavaScript functions in PHP, but so far, no

How can i do this ?
How to tell PHP, that def(word) is a JS function in js.php file ?
I've tried include ('js.php'), etc., but got no results :(
Any help would be apreciated.
Well... you can easily send the Javascript function to the browser with
something like:
$js = file_get_contents('js.php');
echo $js;
HOWEVER... there isn't really a way for PHP to use that Javascript
function. PHP works on the *server* side, whereas Javascript works on
the *client* side.
Now back in PHP4 there was an extension for using Java with the PHP
interpreter, but AFAIK that extension has not been adapted for PHP5 yet.
And PHP5's object model is *closer* to the Java model. So my best
guess is that whoever wrote that extension decided that it was more
trouble than it was worth to get Java working within PHP5?
Definitely worth your time to read this:

[PHP] Re: PHP Javascript compatibilty
I'm developing a WYSIWYG editor using PHP and Javascript (for COM). However, I start having problems when I try to display the page using the .php extension. The Javascript is not working. However, when I save it to HTML, it worked fine. Can anyone please help me? Why is this so? What can I do to get Javascript working with PHP with ease? Any articles on this? Thanks a lot... again. :) If you show me some code I can look at, I might be able to assist you.

Thanks //Mårten _ Chatta med vänner online, prova MSN Messenger: http://messenger.msn.se I'm not quite sure what you are trying to do. Javascript is executing on the browser, php executes on the server, therefore to get anything from the Javascript to php your browser will have to communicate with the server via a request. This could be a form submission, which might be a POST or a GET. Alternatively, it is also possible to send data to a php script via a url e.g. myscript.php?myfield=myvalue. That means that wherever you can get Javascript to cause the browser to issue a request for a url, if the target at the other end is a php script then you can send data to that script. I don't know what you are trying to do, and this is all pretty obscure stuff, but you could for example put a hidden 1x1 image in the page and then get your Javascript to change the location of this image to be a php script with a variable passed on e.g. something like dummyimage.location = /myscript.php?myfield=+myjsvalue; As long as you get the php to send back another empty 1x1 pixel, e.g. via a header(Location: 1x1pixel.gif), then your browser page will stay the same as ever. As it happens I do sometimes do just this in Javascript but it's to get a new dynamic image back without reloading a page. Go to http://tandridge.cpfc.co.uk/tables/0222/graph/2/d7 and then select something different in the Team 1 or Team 2 selection box, and watch the graph at the bottom of the page to see this happen. In the source look for the Javascript function chteam_id() to see how it's done here.
