Hi Paul,
I have recently had to upgrade all of my PHP scripts for several
client's applications, to SWIG MapScript, and your fromWKT() note is a
common one in all of my scripts too. Good news though: your/our scripts
are easily updated for SWIG as follows:
$map = new mapObj("simple.map");
$drawLayer = $map->getLayerByName('drawshape1');
$newshp = new shapeObj(MS_SHAPE_POLYGON);
$newshp = $newshp->fromWKT($curwkt);
(the issue is that you must first declare the new shape object
separately, and then next use that same variable to call & load the WKT)
You're correct that the upcoming release will drop the old native
mapscript, so please definitely don't be afraid to jump into existing
tickets (such as this one that lists a few missing SWIG functions
https://github.com/MapServer/MapServer/issues/1822 ) so we can all work
together on making the 8.0 release great.
Thanks for your feedback,
-jeff

The ‘native’ PHP MapScript will go away with MapServer 8. Will all the
functionality be added to the SWIG PHP MapScript before that happens? I tried
the transition with the change to MapServer 7.4 and was unsuccessful do to
missing pieces (or my lack of knowledge). Thankfully, others also needed the
php_mapscript functionality and put forth a tremendous effort to make the
‘native’ PHP MapScript work with PHP 7. Thank you to all that were involved
with that effort. Here I go again, hoping that I will be able to make the
transition and I still do not see a path forward. Of course, just because I
don’t see a path, doesn’t mean there isn’t one. That is why I am asking how to
add a feature to a layer using SWIG PHP MapScript. The following explains how
I have done this in the ‘native’ PHP MapScript.
I use a layer called drawshape1 in a mapfile to highlight something on a map by dynamically adding a feature to that layer.
LAYER
NAME "drawshape1"
TYPE POLYGON
STATUS ON
COMPOSITE
OPACITY 60
END
CLASS
STATUS ON
NAME "tmpshp1"
STYLE
COLOR 0 0 255
END
END
END
I use a WKT to create the shape that is added to the drawshape1 layer. This highlights the WKT on the image returned by drawQuery().
$map = new mapObj("simple.map");
$drawLayer = $map->getLayerByName('drawshape1');
$newshp = ms_shapeObjFromWkt($curwkt);
$drawLayer->set('status',MS_ON);
$test = $drawLayer->addFeature($newshp);
$img = $map->drawQuery();
Presumably, I could do the following.
$map = new mapObj("simple.map");
$drawLayer = $map->getLayerByName('drawshape1');
$newshp = new shapeObj(MS_SHAPE_POLYGON);
$tmpShape = newshp->fromWKT($curwkt);
$test = $drawLayer->addFeature($newshp);
This doesn’t seem to be finished in SWIG mapscript. I see that in the documentation says TODO.
addFeature( https://mapserver.org/mapscript/mapscript.html#shapeobj shape )int
Add a new inline feature on a layer. Returns -1 on error. TODO: Is this
similar to inline features in a mapfile? Does it work for any kind of layer or
connection type?
I could use inline features to accomplish this also. But this also seems to be
missing in SWIG PHP mapscript and has a TODO by it.
addFeature( https://mapserver.org/mapscript/mapscript.html#shapeobj shape )int
Add a new inline feature on a layer. Returns -1 on error. TODO: Is this
similar to inline features in a mapfile? Does it work for any kind of layer or
connection type?
Does anyone know how can I replace this functionality? Will these TODOs be
done before MapServer 8? It is difficult to work on the transition when pieces
are missing.
Thanks,
Paul
