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;
}

So, einstein.php will be called with a parameter (satellite):

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=3satellite=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.

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.

Re: [PHP] Javascript and PHP interaction
What you *COULD* do is this:
Use .htaccess to force your .css files to *really* be PHP files:
Files ~.css
ForceType application/x-httpd-php
/Files
[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:
?php
header(Content-type: text/css);
?
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

Hi everyone,
I am trying to open a new window after a successful function call (I
don't want to use a href. and onclick). Here's what I have, but for
some reason, in IE the new window does not open (I have popup blockers
disabled). It opens in Mozilla, but with the wrong size. What am I doing
wrong here?
if (insert($lname, $fname, $course, $date, $media1,

echo script type=\text/javascript\\n;
echo
window.open(\add.html\,\resizable=no,width=400,height=200\);;

Yes ... some work on sunday ;), at least to read the list
I took no much time to find out a solution for your problem, but a
possible question could be:
?php
$list = array()
while($row = mysql_fetch_object($result)){
$list[] = ''. $row-picture_url .'';
}
echo implode(',', $list);
}
?
Another solution :
?php
$string = ''
while($row = mysql_fetch_object($result)){
$string .= \.$row-picture_url.\,;
}
$string = substr($string, 0, strlen($string - 1);
?
I have no tested the solutions, so could be some sintax error. But to
give you a couple of examples, hope that helps

Re: [PHP] Javascript to PHP?
I've done this stuff recently. I need to pass whole arrays betn. php and
Javascript (2-way), here is some code:
// PHP var. to JS
function arrFromStr (str2convert) { // make an array from string
arr = new Array();
var posOfQt1 = str2convert.indexOf('\');
var posOfQt2 = str2convert.indexOf('\', posOfQt1+1);
i = 0;
while(posOfQt1 != -1) {
arr[i] = str2convert.substring(posOfQt1+1, posOfQt2);
i++;
posOfQt1 = posOfQt2;
posOfQt1 = str2convert.indexOf('\', posOfQt1+1);
posOfQt2 = str2convert.indexOf('\', posOfQt1+1);
}
return arr;
}
Call this function like this:
layerDesStr = '?=serialize($layerDes[0])?';
layerDes[0] = arrFromStr(layerDesStr);
In case you have a variable don't serialize, just do
myJSvar = ?=$myPHPvar?;
JS variables can be sent to PHP by including them in html forms, nothing
special about it.

RE: [PHP] Javascript to PHP?
My apologies if this has been asked a thousand times. I've just joined the list. I has, but you get that... I can't find any information on passing JavaScript variables to PHP on the same page (i.e. not through the POST information of a submitted form). Is this because it's not possible? Short answer is no. PHP is server-side, Javascript is client-side. You can get variables from php to javascript when your php generates the page to be sent to the browser but you can only get variables back from php when you use browser to server communications (that's usually a form - be it get or post method, or a cookie). To take the load off the server, I'm trying to do a bunch of string manipulations and loops in JavaScript and then hand that info off to PHP once it's done. You'll need to create all the javascript from you php page as it generates and then wait for it all to be done client-side and submitted back to the server.

RE: [PHP] javascript and PHP
since php runs on the server, not on the client, you have to pass the value of data back to the server. Normally, this is done via a GET or a POST from a form or by building a URL and using javascript to load it. (i.e. document.location = 'http://myserver.com/mypage.php?data=Hello%20World';) Then your PHP script can execute and see the value of $_GET['data'] HTH, Cal * * Cal Evans * Journeyman Programmer * Techno-Mage * http://www.calevans.com * -Original Message- From: Steve Buehler [mailto:[EMAIL PROTECTED]] Sent: Monday, April 29, 2002 10:30 AM To: [EMAIL PROTECTED] Subject: [PHP] javascript and PHP Does anybody know of a good/short tutorial about passing variables from JavaScript to/from PHP?

RE: [PHP] javascript to php ????
One way I do this is with the following:
?php
if ($submit) {
// Create a php array.
$t_array = explode(,,$x_array);
print_r($t_array);
exit;
}
?
html
head
script language=javascript
var x = new Array();
x[0] = zero;
x[1] = one;
x[2] = two;
/script
/head
body
form name=f method=post
input type=submit name=submit
input type=hidden name=x_array
/form
!--
Use an onSubmit clause in the form tag to execute a function that
sets any hidden form values you need. This little test just falls
through but it doesn't have to.
--
script language=javascript
// set the hidden input to a comma delimited string
document.f.x_array.value = x.toString();
// alert(document.f.x_array.value);
/script
/body
/html
Hope this helps.

No. You have to realise that JavaScript is client side, and PHP is server side, so -- apart from inserting those javascript values into a form and submitting it using code -- PHP and JavaScript cannot interact.

sure. for GET you would just make a request out of the variables,
i.e.:
var url=/mypage.php?value[0]=+value[0]+value[1]=+value[1];
document.location.href=url;
you can do this in a loop if you want. for POST you would use hidden
fields, i.e.:
document.write('input type=hidden name=value[0]
value='+value[0]+'');
document.write('input type=hidden name=value[1]
value='+value[1]+'');
you could do this in a loop too.

Why, sure! In your FORM tag, use ACTION=test.php. You can send your JavaScript variable as part of the form, in a hidden form field such as INPUT TYPE=hidden VALUE=myValue. The value of the variable will be available the next time test.php shows up as $myValue. You can then manipulate it to your heart's delight.

Re: [PHP] javascript VS php
Javascript (js) is client side and PHP is server side. So what you can do to call the php function is by re-submitting the page, with somekind of a flag from the js to call the php function. You write the php parts like: if($flag) callTheFunctions(args); Reuben D.

Re: [PHP] javascript in PHP statement
I am new to php and I am wondering if it is possible to use a javascript
variable in a php statement for example:
// create sql statement
$sql = "select * from main where businesstype = "consultancy" and
top.upper.villagename = != "0";";
As far as I know, no. Unless "top.upper.villagename" is a field in your
database and the rest is that field's contents (couldn't be ... too many
unescaped double quotes and semicolons). Nope, SQL statements don't work
like that and can only refer directly to data in a database, not php or
any other variables.
You might consider using if statements something like this:
if ($top.upper.villagename != '0') {
$sql = "SELECT * FROM main WHERE business = 'consultancy'";
}
Hope this helps

RE: [PHP] javascript in PHP statement
note that javascript and PHP CANNOT interact natively on the same page...one
is client side and one is server side.
you can pass variables between the two in an HTTP request, however.
page1.php:
script type=javascript
function makeSqlQuery(businesstype,village) {
var sqlQuery;
sqlQuery = "SELECT * FROM MAIN WHERE BUSINESSTYPE="
+ businesstype +
" AND VILLAGE="
+ village
location = "php2.php?sqlQuery=" + sqlQuery;
}
/script
form name=thisform
select name=businesstype
/select
select name=village
/select
input type=button
onclick="makeSqlQuery(thisform.businesstype,thisform.village)"
/form
--
this is a silly way to do it, however, and you should just pass the
variables themselves and construct and run the query in a new request using
php.
you use the same page with control structures on it.

Re: [PHP] javascript and php
It is easy to generate javascript through php,but how to call php through javascript. In fact, I'd like to update some form fields according to events on other fields. I can do this using javascript, but the values should be readed in a MySql database. 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.

Re: [PHP] javascript and php
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) form name=oFrm input name=zip onBlur='fetch();'input name=city /form 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): script opener.document.oFrm.city.value = "$the_right_city"; self.close(); /script 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! -Jrg V.
