Dear List,
How can I define a searchitem with two option lists, where the second
depends on the first.
The idea is to have a first list with categories. When a category is
chosen, the second option lists
Will contain the Points Of Interest of this category, and when the item
is selected, the Point
Of interest has to be shown.
I've tried to write this:
<searchitem name="poi_options" description="POI">
<layer type="postgis" name="mg_poi">
<field type="s" name="rubrik" description="Rubrik"
wildcard="2">
<definition type="options" connectiontype="db"
sort="asc">
<dsn
encoding="UTF-8">pgsql://postgres:passw...@localhost/muenster_geschinen<
/dsn>
<sql>SELECT DISTINCT id, rubrik FROM
tbl_poi_rubrik ORDER BY rubrik</sql>
</definition>
</field>
<field type="s" name="name" description="Bezeichnung"
wildcard="2">
<definition type="options" connectiontype="db"
sort="asc" dependfld="rubrik">
<dsn
encoding="UTF-8">pgsql://postgres:passw...@localhost/muenster_geschinen<
/dsn>
<sql>SELECT DISTINCT name FROM tbl_poi WHERE
rubrik_id = [dependfldval] ORDER BY name</sql>
</definition>
</field>
</layer>
</searchitem>
But there is a syntax error, because [dependfldval] isn't replaced by
the value of the first option list.
