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.

 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 :

 ?php
 print div class='maindiv' id='id_maindiv'my main div/div;
 $new_Width = somefunction();
 print div class='childdiv' id='id_childdiv'
 style='width:.$new_Width.px;'my child div/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,

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
