    If you are having trouble loading the $config->prependTemplateFile and $config->appendTemplateFile variables, make sure that your FTP user has write permissions to the ProcessWire Configuration File. When config.php is write protected ("chmod 444 config.php", or similar) on the FTP server, you may not notice that changes to config.php are not uploaded to the server.

    With the example shown on the above documentation, the output website page layout is fixed in $config->appendTemplateFile in config.php. If I have a page with a different layout, how to deal with it ?

      There are any number of ways you could do it, but simplest would be just to go to your template settings (Setup > Templates > your-template > Files [tab]), and specify a different append/prepend file for that template.

    Hi Ryan

    I am new to PW, having come from building many sites previously with Concrete5. With the Delayed Output approach, and the use of, does this not leave you with one file solely responsible for the structure of every page on the site? For example, what if I have a home page that is full width. I might also have some pages with sub nav, and hence the need for a sidebar. Maybe on my blog page I might want a three column approach with nav on one side and categories on the other.

    Is responsible for having to structure each of these pages? Or, would you approach this differently by having different versions of ie there might be a,, etc

      James, the can be swapped out with whatever you want on a template-by-template basis (see my reply to Adrian below). However, the reality is that there's often going to be as much similar as there is different, regardless of layout. And you want to avoid repeating yourself. So you might choose to make your include different layout (.inc) files, or simply have something like if($sidebar) then output a sidebar column, etc. The default site profile has an example of this. Another way is to define a $layout variable (or whatever you want to call it) in your that indicates a default layout file. Then any of the template files can choose to change that. Then the file can take that $layout into account to render or include accordingly.

    Suppose hat I have to create a set of new pages which uses a template(say template_2)different than the rest of the website. In my site/config, I have
    $config->prependTemplateFile = '_init.php';
    $config->appendTemplateFile = '_main.php';

    However, I do not want the sidebar and navigation I had defined in the main.php for the template_2. I want to have different footer,header and sidebar. Any suggestions how I can add an exception such that when I load template_2, I should not include the original _init.php and _main.php and should load from some _init2.php and _main2.php?
