Paul, Can you tell me what exactly has been changed in drawmap.php? I'm having a few problems with the latest file (modified Sept 30th). It appears the mapimage takes on the size of the querymap. I tested this, and changing the querymap size in my mapfile does in fact change the size of the mapimage. Is it supposed to work like that? Also, the new drawmap file doesn't seem to take in the nWidth and nHeight GET variables from the URL. I used to be able to pass them in, which is handy for changing imagesize on the fly. Also, my legend images do not appear, because it cannot seem to find the template file (see below), even if I use an absolute URL. Does it look in a different place? If I replace the drawmap.php file with the one from June 7th, it all works well again. This is what my PHP log file says if I use the latest version of drawmap: [30-Sep-2004 08:41:51] PHP Warning: [MapServer Error]: generateLegendTemplate(): Error while opening template file. in C:\chameleon\epra\htdocs\widgets\LegendTemplate\LegendTemplate.widget.php on line 503 [30-Sep-2004 08:41:51] PHP Warning: [MapServer Error]: msInsertHashTable: Invalid hash table or key in C:\chameleon\epra\htdocs\widgets\LegendTemplate\LegendTemplate.widget.php on line 503 [30-Sep-2004 08:41:51] PHP Warning: [MapServer Error]: msInsertHashTable: Invalid hash table or key in C:\chameleon\epra\htdocs\widgets\LegendTemplate\LegendTemplate.widget.php on line 503 [30-Sep-2004 08:41:51] PHP Warning: [MapServer Error]: msInsertHashTable: Invalid hash table or key in C:\chameleon\epra\htdocs\widgets\LegendTemplate\LegendTemplate.widget.php on line 503 [30-Sep-2004 08:41:51] PHP Warning: [MapServer Error]: msInsertHashTable: Invalid hash table or key regards, Jacob
The latest change introduced the capability to have persistent queries. I found that I have an un-committed change to drawmap.php that may fix this problem. Essentially drawmap.php is currently always using drawQuery but it should only be using drawQuery if a persistent query was found. I am not sure what the interaction between draw, drawQuery, and the QueryMap object is. I suspect that I should probably modify the QueryMap object temporarily (at least it's size) before doing a drawQuery. I will also check the nWidget / nHeight problem. The LegendTemplate thing is a separate issue unrelated to drawmap I think.
if this isn't fixed by beta 3 then we'll need to address it for RC1. Jacob, did you try with latest CVS?
Yes, I did. Sorry, forgot to mention. I tested it with the sept 30 version of drawmap. I don't get any PHP errors in my log, but it still gets the size from the querymap in the mapfile, ignoring the size of the actual mapobject. I managed to get my templates to work again, but I have to use an absolute URL now. I found the previous solution easier, because I don't like hardcoding the servername (I tend to move sites across laptops and pc's a lot). It still doesn't get the height and width from the POST variables, but this is not a major disaster; version 1.0.4 didn't do this by default either, and it's easy for me to change if I want to. For some reason, when I update from the CVS, I don't get the folder /chameleon/htdocs/common at all. I use wincvs, which says: cvs update -P -d It happened since the CVS was restructured. I started off with a clean copy. Jacob
Was the drawmap.php file updated since sept 30? If it was, then I did not use the latest version (sorry, my mistake).
Got latest version now after some messing about. ....don't like CVS..... All is happy; height and width using POST parameters works, templates work, mapsize no longer coming from querymap size. Sorry for the overload of messages.
no problem :> cvs question replied to via list.
