RE: [PHP] Calling Javascript-function from php-script ...
I'm not quite sure what you mean... If Javascript were disabled then this whole argument would be moot. Since our method requires Javascript to properly function we're really not interested in that particular situation. :) There are two ways a PHP script (or any scripting language for that matter) can send input to a Javascript. One, by dynamically generating a local Javascript with the lines of code necessary to perform a certain task. Two, by sending information through the URL string to a remote Javascript which runs functions based on that information. Classic Input/Output. It doesn't matter where the input is coming from so long as the program gets what is expecting. So in this sense the two unrelated programs (one server side, one client side) are communicating, just not directly. Bottom line is the method works so I don't understand what there is to debate. See here for a working example http://www.helpelf.com/fetch_data.html It's not very sophisticated yet (all the junk left in the URL, et al). But it does what I'm talking about. You can copy paste this Javascript into any web page and it'll return the same database information gathered by the PHP script. -Kevin -Original Message- From: Alexander Skwar [mailto:[EMAIL PROTECTED]] Sent: Tuesday, March 19, 2002 4:27 PM To: Kevin Stone Cc: [EMAIL PROTECTED] Subject: Re: [PHP] Calling Javascript-function from php-script ... »Kevin Stone« sagte am 2002-03-19 um 14:11:42 -0700 : Not entirely true.

Re: [PHP] Calling Javascript-function from php-script ...
I think the point here is that it be made clear to those who might get confused that the javascript (unless it's a server-side script) is running in a browser and as such there is no way for the server to 'make a call to it by URL.' The Javascript can call the server but the server-side PHP script cannot call the client. Therefore, no PHP script can 'call' a javascript function.

RE: [PHP] Calling Javascript-function from php-script ...
I think the point here is that I'm right and you're wrong *JUST JOKING!* Seriously you're absolutely right, a PHP script can not activate a Javascript function. What I'm saying (and what I wanted the original poster to understand) is that a PHP script CAN send input to a Javascript, and based on that input run a specific function. A Javascript can activate a PHP function in the same way. So in this way a Javascript and a PHP script can in fact communicate. (please note the preceeding a before the words Javascript and PHP.. we're not talking about the languages here only the physical scripts, because we could be talking about any two interpreted languages). *phew* Are we done yet? I really need to get back to work.

RE: [PHP] Calling Javascript-function from php-script ...
Then you need to do it like this:
? if ($myVal == ---) { ?
script language=JavaScript
alert(DOH!);
/script
? }; ?
But you can not make PHP call javascript functions directly.

Re: [PHP] Calling Javascript-function from php-script ...
PHP cannot call a javascript function.
but PHP can examine the incoming variables
and then output Javascript to the browser
to do the appropriate work.
for example, calling $text.php?this=5
pops up an alert saying this=5
test.php
?
print script\n.
alert('this='+. $this .);\n.
/script
?

RE: [PHP] Calling Javascript-function from php-script ...
Not entirely true. Javascript is directly linked to HTML and HTML is
directly linked to PHP so you can have PHP talk to Javascript through
HTML.
So here's a very simple example of a Javascript and PHP script (on
separate servers) talking to one other...
-
html
titlemyhtmlpage.html/title
script language=javascript
if (location.search.substring(1))
{
// Parse and evalulate the returning GET string.
var urlStr =
window.location.search.substring(1);
var name = urlStr.split('=')[0];
var value = urlStr.split('=')[1];
document.write(value);
}
else
{
document.location(
http://www.here.com/myphpscript.php?request=current_time;);
}
/script
/html
-
-
?//myphpscript.php
extract($HTTP_GET_VARS);
$origin = $HTTP_REFERER;
if ($request == current_time)
{
$information = time(); // err.. whatever the time function
is in PHP
header(Location: $origin?return=$information);
}
?
-
In this example the Javascript is activated when the page is visited.
If no information is being passed in the URL string then it
auto-redirects to a PHP script on another server. The PHP script
extracts the variables from the GET string and redirects back to the
originating script with the requested information. Now when the
Javascript reads it itll parse out the value and write it to the screen
closing the loop. Pretty slick eh?
