That's incorrect.  A form will function

no ids, and it's quite possible for JavaScript 
to address the form elements using only the 
names (in fact, it's easier than via the ids as 
there's a short syntax for it!).


Incorrect or not, it works.

Well, true -- hence the qualifiers in "*primary* identifier" and "*may*
demand"!

8< snip!

True, you can access an input named "myInput" in a form named "myForm"
by simply writing:

document.myForm.myInput.value = "Hello!";

BUT... for CSS, it's also quite easy to reference something by name:

[name="myElement"]
{
color: blue;
font-size: 10pt;
}

Mário:

The key here to remember is that javascript uses

your variables in that form and they will work 
between javascript and php. Such as:


onclick="javascript:GetImage(this);">Einstein 2


Note the change of "this" in your js call -- you 
can do that and not have to provide the number.


Also put in an action="whatever" into your form 
and collect the selection via $_POST['rad'];


That will do what you want.

You could do that.  Also, I'd suggest using $_GET instead of $_REQUEST.
Request works,b ut it is very broad.  $_GET is more specific/secure.

[PHP] JavaScript and PHP

[Mário Gamito]

Hi,

I have this HTML/JS page that switches images clicking on the radio 
buttons and call template.php with the image ID as parameter: 
http://portulan-online.net/einstein.html


Now, I need to make it a PHP page, because it is going to receive a 
parameter from the URL that calls it and pass it as is to template.php



So, einstein.php will be called with a parameter (satellite): 
http://portulan-online.net/einstein.php?satellite=123


After that, in einstein.php, I do:

$satellite = $_REQUEST['satellite'];

Next thing, I need the action in the JavaScript to be, for example:
http://portulan-online.net/template.php?id=3&satellite=123

What I don't know is how to mix the "PHP variable" satellite with the 
image ID here:
document.getElementById('image1').src = 
"http://portulan-online.net/einstein-"; + ID + ".png";


I've tried putting einstein.php all inside an "echo", but the radio 
buttons and the submit button stopped working.


Does anyone knows how to do this ?

Any help would be appreciated.

Warm Regards,
Mário Gamito

Re: [PHP] Javascript and PHP interaction

[Richard Lynch]

What you *COULD* do is this:

Use .htaccess to force your .css files to *really* be PHP files:


  ForceType application/x-httpd-php


[NOTE: Depending on your server configuration, the
application/x-httpd-php part could be *ANYTHING* the sysadmin felt was
appropriate...]

Inside your CSS, you now have the full-blown power of PHP to output
whatever you think is "right" for the CSS.

But you'll need to tell the browser that this *IS* CSS output, so
you'll need:

at the very tip-top.

Note that browsers can cache the CSS, so you'll want to add more
headers to stop that, probably, or have a random value in the LINK tag
in your HTML document.

I think you can not do it with PHP.
But you can do it with javascript. you have to read the offsetWidth
property of the object, then set it's style.width like

if (document.getElementById('whatever').offsetWidth > 300) {
document.getElementById('whatever').style.width = 300;
}

hope that helps

[PHP] Javascript and PHP interaction

[Alain Roger]

Hi,

I would like to know if there is a way how PHP code can extract from
ElementID some property values.

for example, i have the following PHP page :

my main div";
$new_Width = somefunction();
print "my child div";
?>
in my CSS file (which is link to my HTML page), i have :

.maindiv
{
width : 300px;
height : 400px;
background-color : #EEBBEE;
}
.childdiv
{
background-color : #BB;
}

my PHP code should be able :
- to extract the width of id_maindiv ID (so to get 300px) and to reduce it
by 50px

the problem is that i tried with Javascript and if the property
(style:width) is not define DIRECTLY to HTML code (but only in CSS file),
the javascript is not able to return the value (but only 'undefined').
So i would like to know if PHP could help me in this way ?

thanks a lot,

You can only request a new page. Period.
PHP runs on the server, button clicks are evaluated on the client

Re: [PHP] javascript and php

[Jørg V . Bryne]

In general:
We made a script which did this, however a bit limited because of the
client/server-problems mentioned.
The script is part of a registration-form, and pick out a city based on the
zip entered. We didn't want the list of zipcodes and cities in JS since it
would be quite huge.

Don't remember the excacts but in general: (simplified model)

 


Fetch() is a function that opens a new pop-up window at 50x50px, and set the
url-property of this window using JS (ex:)
 var strURL = "find_city.php?zip=" + document.oFrm.zip.value;

The find_city.php script recieves the zip in a get-var, and can connect to
mysql and retrieve the city etc. and closes itself.

find_city then outputs JS (ex):

 opener.document.oFrm.city.value = "$the_right_city";
 self.close();


The "drawbacks" here is a window flashing a short second or so...
You can make this thing run queries or whatever...

Wrote the above from memory, so the syntax might be a bit of, but the flow
is the same.

have a nice day!

You're in a serverside, clientside problem. You want the client to execute
the PHP code, which it cannot. If you want to update the form fields with
some other data, you have to provide the page you sent to the client with
all the needed data beforehand.
