I want to nest the output of one plugin inside the values provided to another:-
The 'outer' plugin is the SQL plugin, the inner one is my own which
expands a link parameter, thus I want to write something like this:-
<sql db="sqlite:////var/www/boat/data/meta/boat.db" wikitext="enable"
special="plain"..>
SELECT Summary from bePlaces where Name like '<xv>name</xv>'</sql>
The<xv>name</xv> expands to a place name and is fed into the SELECT
being run by the SQL plugin.
Is this even possible and, if so, how does one do it? I obviously need
to get Dokuwiki to run the<xv> plugin expansion before the<sql> one.
Any/all advice would be very welcome.
You appear to be using plugin:sql, which is a syntax plugin. If you
look at the code in syntax.php, in the handle method, you will find the
following case:
DOKU_LEXER_UNMATCHED
It is here that the queries are collected (and subsquently passed on to
the render method). Before allowing the queries to be passed along,
replace your place holders with the values from the query string.
case DOKU_LEXER_UNMATCHED:
$queries = explode(';', $match);
/* add the following code */
$name = $_GET['my_name'];
$queries = str_replace('<xv>name</xv>', "<xv>$name</xv>",$queries);
This will replace the place-holder 'name' with the same value in each
query in the array. This should work, and if you have multiple
place-holders to replace you can do them one at a time or all at once
using arrays (see the php documentation).
