PHP is serverside; everything is parsed before the user ever sees the document. Javascript, on the other hand, is interpretted by the browser. The two languages are unrelated, so it's not possible to call a PHP function through a clientside feature. Some PHP functions can be implemented by javascript. What is it that you intend to accomplish?

something like that:
--------------
<html>
<title></title>
<?php
function roll(){
$link1="</td></tr><tr><td>sub1</td></tr><tr><td>sub2";
}
?>
</head>
<body>
<table width="130" border="1">
<tr>
<td onClick="<? roll(); ?>;">
link1
<? echo $link1; ?>
</td>
</tr>
</table>
</body>
</html>
------------------------------------
thanx.

No, this is not the best approach. You can use <div></div> and use Javascript to add data to DIV layer on click, by using  divid.InnerHTML

Hey Orik,

The best way that I can think of would be to use hidden rows.

<table>
 <tr id="Section1" style="display:none;">
   <td>
     Content
    </td>
  </tr>
  <tr id="Section2" style="display:none;">
    <td>
      Content
    </td>
   </tr>
</table>

Then for you buttons in the onclick call a javascript function that shows or hides rows.

Use this function:

function showHideRow(el, showhide) {
  if (document.all){
        var whichRow = document.all[el];
        if(showhide == "show" ) {
            whichRow.style.display = "";
            } else {
            whichRow.style.display = "none";
              }
  } else if (document.getElementById){
        var whichRow = document.getElementById(el);
        if(showhide == "show" ) {
            whichRow.style.display = "table-row";
        } else {
            whichRow.style.display = "none";
        }
  }
}

So:

onClick="showHideRow('Section1', 'show'); return false;"

will show hidden section1.

onClick="showHideRow('Section1', ''); return false;"

will hide section1.

Hope this makes things easier.

Sean, i'm asking because as i said i have something that is working but there's the browsers issus that are not solved- so if i'm replacing it it's better to have a good start (to have a code that will be more fitbale to other browser than IE).
thanx. ori.

Hey Orik, this will work on mac on ie, safari, mozilla firefox...
and pc: ie, mozilla firefox, netscape all latest versions.

That's all I currently have on my system but the only thing limiting cross-browser would be the javascript function
showHideRow.

 if (document.all){
and
  } else if (document.getElementById){

check for two different document object types so logically you could add as many as you want.

function showHideRow(el, showhide) {
// add opera compat
   if (navigator.userAgent.indexOf("Opera") != -1) { //Opera
     whichRow = eval('document.all.' + el);
       if(showhide == "show" ) {
          whichRow.style.display = "table-row";
       } else {
          whichRow.style.display = "none";
       }
   }  else if (document.all){
       var whichRow = document.all[el];
       if(showhide == "show" ) {
          whichRow.style.display = "";
            } else {
          whichRow.style.display = "none";
              }
  } else if (document.getElementById){
       var whichRow = document.getElementById(el);
       if(showhide == "show" ) {
          whichRow.style.display = "table-row";
       } else {
          whichRow.style.display = "none";
       }
  }
}

This function adds in opera capability.

You can't do what you need with PHP, the concept is wrong in itself. If browser doesn't support DOM, then you can't do it. Mozilla supports DOM, old versions don't, Netscape/Mozilla started supporting it much later than IE.

Could you explain better what you need this code to do? so far, I see Sean's solution as the best and I dont think you'll find a lot of browsers that dont support the mentioned solution. I am pretty sure the vast majority of people that visit your site use either MSIE or the latest Mozilla.

Also, i think you need to understand a bit more of PHP and JS. Like it has been mentioned before, PHP works serverside and JS works clientside, which means that PHP functions work while the document is still being procesed at the web server and JS is processed when the document reaches the browser at the client machine which means you CANT do the onClick call of a PHP function UNLESS you actually referred to another URL.

All is not lost, though. You CAN do some things like submiting to a PHP document using java or you can also navigate to such document using a popup window (if you wish your main window to stay on the same document).

Just a couple of suggestions.. elaborating on your question would help us come up with a solution too.

Hope this helps.
