This week, I ' ve been prepping for a talk on Quercus in which I promised to show a demo of Spring MVC using a PHP view. So, means that I actually had to do it. Turns out it is quite easy and PHP makes for a very nice, compact view technology for Spring MVC. This was a bit of tease since the code for this won ' t go out until at least next week, but since a number of people has been En asking for the while, I thought I ' d give a preview ...

First, let me show how it looks by using the sample "Imagedb" Application this ships with Spring. Here's a screenshot of the app in action:

Basically, you upload an image to the page and it keeps track of what you've uploaded in a database. Here is the JSP and PHP views Side-by-side:

}

} ?>

< table border="1" cellspacing="0" cellpadding="5"> < form action=" Imageupload " method=" POST " enctype=" Multipart/form-data ">

foreach ($images as $image) { ?> < table border="1" cellspacing="0" cellpadding="5">

</table> < P> <%%>

< table border="1" cellspacing="0" cellpadding="5"> < form action=" Imageupload " method=" POST " enctype=" Multipart/form-data ">

</form> </table>

"Cleardatabase" >clear database

< body> </table> < p> </form> </table>

"Cleardatabase" >clear database

<%@ page session="false"%> <%@ page import="Java.util.List, Java.util.Iterator, Org.springframework.samples.imagedb.ImageDescriptor"%> < body> <% List images = (list) request.getattribute("Images") ; for (Iterator it = Images.iterator(); It.hasnext(); { imagedescriptor image = (imagedescriptor) it. Next(); %> < table border="1" cellspacing="0" cellpadding="5">
"10%" >name	<%= image.getname() %>
"2" > "imagecontent?name=<%= image.getname ()%>" height=">
Description (<%= image.getdescriptionlength() %>)	<%= image.getshortdescription() %>
"10%" >name	"Text" name="name">
Content	"File" name="image">
Description	"description" </span> cols=<span class= "St0" > "+" </span> rows=<span class= "St0" > "5" </ Span>>
"2" >"Submit" value="Upload image">
"10%" >name	getName, $image () ?>
"2" > "Imagecontent?name= getName ()?>" height=">
Description ( = $image-getdescriptionlength() ?> )	getshortdescription, $image () ?>
"10%" >name	"Text" name="name">
Content	"File" name="image">
Description	"description" </span> cols=<span class= "St0" > "+" </span> rows=<span class= "St0" > "5" </ Span>>
"2" >"Submit" value="Upload image">

Jsp:

<%@ page session= "false"%> <%@ page= "Java.util.List,"%>
    <%< span="">= (List) request.getattribute ("Images"  < span="">    < span="">  (Iterator it =< span="">=   < span=""> %>
    
 
 
      
     
  
 
   
 
    
Name
 
    
<%= Image.getname ()%>
 
   
 
   
 
    
"Height=" >
 
   
 
   
 
    
Description (<%= image.getdescriptionlength ()%>)
 
    
<%= image.getshortdescription ()%>
 
   
 
  
     
    
 
<%< span="">%>

     
    
 
Clear Database

< span="">

 
 
  < span="">< span="">(?>< span="">< span="">< span=""> 
      
  
  
 
       
   
   
 
    
 
     
Name
 
     
 
 
    
 
    
 
     
->getname ()?> "height=" >
 
    
 
    
 
     
Description (  ->getdescriptionlength ()?>)
 
     
 
 
    
 
   
      
  
  

       
   ?>

      
  
  

What I think is interesting between these, and the PHP, even though it ' s calling Java objects, has a simpl ER syntax. It's not a major issue, but you can see the PHP is as reasonable as any other view for Java.

Now how does you configure it? Just Add the Quercusview class to a urlbasedviewresolver and give a php suffix and you ' re-done:

    < span="">  < span="">  < span=""> < span="">< span="">< span="">< span="">< span="">< span="">< span="">< span="">< span="">< span="">< span=""><   c24>  < span="">  < span="">  < span="">  < span="">  < span="">< span=""> < span="">< span="">< span=""> < span="">< span="">< span=""> < span="">< span=""><   /c55> < span="">  < span=""> 

If you ' re interested in the implementation ... The view is pretty easy-connect up once I learned Spring ' s view API. It ' s essentially a servlet.service () call with a map of model values. So the Quercusview class above are just a modified quercusservlet that injects the model values as PHP globals. I ' m not sure so that's right just yet, but it's a start. The other option would is to put the values as PHP superglobals or in a specialized Spring array.
