In Smarty 3.1 template inheritance is a compile time process. All the extending of {block} tags
|
|
is done at compile time and the parent and child templates are compiled in a single compiled template.
|
|
{include} subtemplate could also {block} tags. Such subtemplate could not compiled by it's own because
|
|
it could be used in other context where the {block} extended with a different result. For that reasion
|
|
the compiled code of {include} subtemplates gets also merged in compiled inheritance template.
|
|
|
|
Merging the code into a single compile template has some drawbacks.
|
|
1. You could not use variable file names in {include} Smarty would use the {include} of compilation time.
|
|
2. You could not use individual compile_id in {include}
|
|
3. Seperate caching of subtemplate was not possible
|
|
4. Any change of the template directory structure between calls was not necessarily seen.
|
|
|
|
Starting with 3.1.15 some of the above conditions got checked and resulted in an exception. It turned out
|
|
that a couple of users did use some of above and now got exceptions.
|
|
|
|
To resolve this starting with 3.1.16 there is a new configuration parameter $inheritance_merge_compiled_includes.
|
|
For most backward compatibility its default setting is true.
|
|
With this setting all {include} subtemplate will be merge into the compiled inheritance template, but the above cases
|
|
could be rejected by exception.
|
|
|
|
|
|
If $smarty->inheritance_merge_compiled_includes = false; {include} subtemplate will not be merged.
|
|
You must now manually merge all {include} subtemplate which do contain {block} tags. This is done by setting the "inline" option.
|
|
{include file='foo.bar' inline}
|
|
|
|
1. In case of a variable file name like {include file=$foo inline} you must use the variable in a compile_id $smarty->compile_id = $foo;
|
|
2. If you use individual compile_id in {include file='foo.tpl' compile_id=$bar inline} it must be used in the
|
|
global compile_id as well $smarty->compile_id = $bar;
|
|
3. If call templates with different template_dir configurations and a parent could same named child template from different folders
|
|
you must make the folder name part of the compile_id.
|
|
|
|
|
|
In the upcomming major release Smarty 3.2 inheritance will no longer be a compile time process.
|
|
All restrictions will be then removed.
