 Posted: Sat May 17, 2014 9:18 am Post subject: modifying template source from block function |
 |
|
Hi,
I would like to get and modify the whole template from a block function.
How can I do that?
The story:
My block function manipulates fine the content of an xml tag.
However there is a style defined for that tag in the template prior to that in the xml and I would like to change that as well. As I am working with a WYSIWYG editor I will not be able to separately put a smarty tag on the style.
this is the content that the block function gets
| Code: | | <draw:frame draw:style-name="fr1" ...>....</draw:frame> |
I can get the style name 'fr1' from here.
Somewhere before that in the template the style is defined like this:
| Code: | | <style:style style:name="fr1" ...">....</style:style> |
I would need to get the content of the template to find the style element and modify it and put it back to the template source.
Thanks for the help.

| Unfortunately that wouldn't work because I need to get the id from the block first to find the part I need to processes. |

Thanks for the help, that might work.
If I understand it the idea is:
| Code: |
function smarty_block_myfunction($params, $content, $smarty, $repeat) {
...do things with block $content
$id = id_from_block
$smarty->registerFilter("output", do_things_wih_template);
return $content
}
|
1. How can I pass parameters to this filter? (eg. the id I got?)
2. smarty_block_myfunction could be called multiple times in a template, will it register multiple output filters with different parameters |

In the output filter you can read template varibales.
| Code: | | $value = $template->getTemplateVars('foo'); |
Or use regex in the filter to get the name from the 'draw:style-name="fr1"'. |

The output filter sounds good.
I think i will try to put the info that i get in the block into the smarty object, than get them in the filter. Thanks for the help. |
