php - Modify article on the fly in Joomla -

i can change title placing next line template:

$doc->settitle('my new title');

but method modify article's 'fulltext' in same way?

short answer: yes, content plugin.

details

if can use $doc->settitle(), assume somewhere before line there's line says:

$doc = jfactory::getdocument();

but document refers whole page, you're setting html <title> tag.

if want change article text, you're dealing result of specific component, i.e. com_content, part of whole document.

there more 1 ways change it.

if want change whole page content in template, have do:

$buffer = $doc->getbuffer(); // ... whatever modification buffer $doc->setbuffer($buffer)

quite simple do, it's not idea put kind of logic in template (if ever want change template, you'll have copy / paste code).

the core of solution same before, put logic in system plugin, hooking on onafterrender event. buffer, modify it, set buffer.

good solution simple modifications and/or if want make sure modifications applies any part of page.

a content plugin applies articles body, product descriptions, , similar text parts.

you should use if want modify parts.
