SSI and javascript problem

**Cepola** · 01-05-2008, 05:59 AM

Hi folks, i'm new on the forum and this is my first post (who cares?) Well, i'm also new to php and all that stuff, so i've encountered a problem which i think isn't so problematic after all. I didn't know whether to post this thread in the javascript forum or here, but i thought that the actual problem lays in php.
What i was trying to do is the following: a html form with some radio buttons and a second part which depended through a javascript to every single button an which should appear when triggered by the onClick function.
Here is just one case, in order that you understand the whole thing:

HTML Code:

<head>
      <script type="text/javascript">
function AdventPrague()
{
document.getElementById("additional").innerHTML="<?php include(event_forms/advent_prague.htm); ?>";
}
      </script>
        <script type="text/javascript">
</head>
<body>
<label>
<input type="radio" name="event" value="advent_prague" onClick="AdventPrague()">
Advent Prag</label>
<div id="additional"></div>

Everything works when I directly insert HTML through the javascript but it would overload the file size, so i'd like single files to load on every onClick, but the PHP include won't work, as i suppose the server isn' triggered. Can you help please?
PS the whole form is here http://www.musicandfriends.com.hr/form.php

I am pretty sure you will need to use AJAX/HttpRequest but thats my next thing to learn so I unfortunately cant give you any specifics.

Yes this is a Js problem.

As mentioned by Truly this would be best done using the Http request object.

The script below will work.Just pass the requested page (event_forms/advent_prague.htm in this case) as an argument in the AdventPrague function.

HTML Code:

<head>
      <script type="text/javascript">
function AdventPrague(a)
  {
  var xmlHttp;
  try
    {
    // Firefox, Opera 8.0+, Safari
    xmlHttp=new XMLHttpRequest();
    }
  catch (e)
    {
    // Internet Explorer
    try
      {
      xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
      }
    catch (e)
      {
      try
        {
        xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
        }
      catch (e)
        {
        alert("Your browser does not support AJAX!");
        return false;
        }
      }
    }
    xmlHttp.onreadystatechange=function()
      {
      if(xmlHttp.readyState==4)
        {
       document.getElementById('additional').innerHTML=xmlHttp.responseText;
        }
      }
    xmlHttp.open("GET",a,true);
    xmlHttp.send(null);
  }

   </script>
</head>
<body>
<label>
<input type="radio" name="event" value="advent_prague" onClick="AdventPrague('event_forms/advent_prague.htm')">
Advent Prag</label>
<div id="additional"></div>

Nope.
You cannot use a client side script to insert server side php.
Server side code runs and ends before the page is even sent to the client and javascript code starts to run.

Well, now I'd like to know if it's possible to include the AJAX stuff in a variable as i have many functions in which i'd like to reuse it. Tanks in advance!

anyone?

I would guess we are not sure what you mean by;

I vote for this solution

In the original code, you may have problems with codification of html into javascript string.
