[opencms-dev] Load templates dynamically

[Mario Jäger]

Hi,

Overall, your procedure to include a template dynamically is right. But, 
the following remarks:

1) Using OpenCms templates in the right procedure would also use the 
"element" attribute in the <cms:include> tag, like:

<cms:include ... element="head"/>

and

<cms:include ... element="foot"/>

Do you know the procedure to split the template jsp into elements using 
the <cms:template> tag?

2) Instead of hard coding the template files in the jsp, you also could 
use the "template" property. And for example, you could create your own 
second template property for the other user agent, like 
"template_mobile". Then, regarding the remark in (1) you could include 
the template for the other user agent in that way:

<cms:include property="template_mobile" element="head" cacheable="false"/>

The advantage is, that you only need to change the property to change a 
template. And that you can use another template for special subfolders.

3) Since OpenCms V8 there is the <cms:device> tag. With that tag you get 
the device where the page is called from. Code inside that tag is only 
executed for the configured device in the "type" attribute. As example 
using that tag for the device "iPod":

<cms:device type="ipod">
    ...
</cms:device>

Unfortunately, the iPad is still not supported by that tag.

If you use that tag in the template jsp, you only need one template jsp 
then.

Kind Regards,
Mario.
