[Geomoose-users] Item Query Problems and Question

[Dan Little]

This is actually one of the problematic parts of using MapServer templates.  It can be a real bugger to diagnose when it does work.  Of course, when they do work they work beautifully.

The parameters for processquerytemplate are not related to the features list.  They are "mostly" for internal MapServer business that we don't need to modify, hence, they are functionally both "null."

Dumping the result is the clearest cut way to see if anything is returned.  If the result is blank there are a few causes:
1) Complete feature miss.
2) Malformed Templates.

If you're getting results then I'd lean towards the second and try to figure out why MapServer is being so hateful.  This particular diagnostic task has had me leaning towards getting MapServer *out* of the template business.  Possibly OGR/GDAL bindings to python/ruby + Mako/Erb would be more useful.  This does not help you but I feel better having espoused a potential long term fix to these troubles.  :-)

>I was looking at query.php and dumping the results of some variables.  Around line 359, an array is pushed out to variable $resultfeatures, when I dump that variable using var_export I am able to see that there is results getting passed.  A few lines after that variable there is a line of code "$results = $map->processquerytemplate(array(), false);" which I am guessing processes the feature results using the template specified in the MAP file and pushes it out to html code.  If I do a variable dump on $results it is blank.
