Hello!
Please help me to include files relatively:
(res==1 ? not_found.lzx : found_result.lzx) and default is empty_result.lzx.

Where is my mistake below?


<class name="l">
<attribute name="href" setter="setHref()"/>
<method name="setHref">
var w = LzBrowser.getInitArg('res');
var hr;
if(w == "1"){
hr="not_found_result.lzx";
}
else if(w == "2"){
hr="found_result.lzx";
}
else{hr="empty_result.lzx";
}
this.setAttribute("href",hr);
</method>
</class>
<l/>


or


<script>
var w = LzBrowser.getInitArg('res');
var hr;
Debug.write(res);
switch(w){
case "1":
hr='not_found_result.lzx';
break;
case "2":
hr='found_result.lzx';
break;
default:
hr='empty_result.lzx';
}
Debug.write(hr);
var url=new LzURL(hr);
</script>
<include href="${hr}"/>



Thank you!

I don't think you can dynamically include an LZX file. Remember that those constraints you're writing are being resolved at run-time, i.e. after the app is downloaded and has started ont he client.

The LZX reference page for <include> shows href as being an URL type tag attribute. The page that explains what the different types are is:

http://www.laszlosystems.com/lps-2.2/docs/reference/info-attribinfo.html#typetag

... but it doesn't mention URL. I've filed a bug on this.

could you build the switch into say PHP code embedded in an HTML wrapper page to select the appropriate lzx page?

Hi, Antun!

Does it mean that a variable ${hr} is not recognizible at all at this 'run-time' moment?

But if i'd like to include dynamically texts or images and so on - wonn't this structure work also?

Ok, I'll try to manipulate with files in another way. And thanks for reply.

Hello, d~l!

If this is the only way to include files dynamically..

The question is remaining:

do you mean simple PHP-code file inclusion or this method:


<body>
<script type="...">
lzEmbed({url:'index.lzx?lzt=swf'});
</script>
</body>


When i put lzEmbed in an HTML code file - it work fine, but when i put it into an JSP code file - it doesn't handles. This make me think that in a PHP code it would be also not recognizible....

I had in mind the approach of building a case switch (in PHP) into your HTML wrapper page.

But if (like me) you are interested in dynamic graphing, driving SVG etc. .. then I wrote up a few experiments here

Laszlo & PHP (http://www.laszlosystems.com/developers/community/forums/showthread.php?s=&threadid=1321&highlight=PHP)

Instead of JSP I have adopted a phpservlet (http://tools.herberlin.de/phpservlet/index.shtml) which is written in java .. allowing PHP to run in CGI mode on Tomcat server.

The same principles apply as in using helloworld.jsp.lzx pre-processed requests.

i.e. call helloworld.php.lzx

But note the warning that this pre-processed request "idiom" may not be supported in future.

I find that php.lzx apps (i.e. with embedded php script) work well .. but of course the apps need to be recompiled each time there is a change.

With PHP you can also have remote server includes. See earlier thread on includes (http://www.laszlosystems.com/developers/community/forums/showthread.php?s=&threadid=1093&highlight=PHP)

You can write a constraint in the form <view src="${...}" />, but the app will make the request for that image at run-time, not at compile-time. A laszlo application can make data and media requests at run-time.
