Look at the TEXT label for the Flood Elevation layer.
TEXT ([ELEVATION]')

I've had all kinds of problems before when I miss a " or '

I have two layers that look like this:
LAYER
NAME "Flood Zone"
STATUS ON
DATA "flood_zo"
TYPE polygon
MAXSCALE 300000
UNITS FEET
CLASS
COLOR 68 126 171
OUTLINECOLOR 11 57 92
END
GROUP "Layers"
END
LAYER
NAME "Flood Elevation"
STATUS ON
DATA "flood_el"
TYPE line
UNITS FEET
MAXSCALE 20000
CLASS
COLOR 68 155 255
TEXT ([ELEVATION]')
LABEL
TYPE TRUETYPE
FONT arial
SIZE 8
POSITION cc
COLOR 0 0 0
ANGLE auto
MINFEATURESIZE 1
END
END
REQUIRES "([Flood Zone] = 1)"
END
Notice the "REQUIRES" tag. These two layers cause no problems. However,
I also have these two layers further in the map file:
LAYER
NAME "Buildings"
STATUS ON
DATA "bldg1"
TYPE polygon
MAXSCALE 15000
UNITS FEET
LABELITEM "ADDRESS"
LABELCACHE on
LABELMAXSCALE 6000
CLASS
COLOR 220 149 146
OUTLINECOLOR 190 95 96
LABEL
MINFEATURESIZE 12
TYPE truetype
FONT arial
ANTIALIAS true
ANGLE auto
POSITION cc
COLOR 0 0 0
OUTLINECOLOR 255 255 255
BUFFER 3
SIZE 8
END
END
TOLERANCE 3
TEMPLATE "x"
METADATA
search_field "FULLADDR"
search_fields "FULLADDR"
search_aliases "Address"
END
GROUP "Layers"
END
LAYER
NAME "Buildings 0"
STATUS ON
DATA "bldg0"
TYPE polygon
MAXSCALE 15000
UNITS FEET
CLASS
COLOR 168 168 168
OUTLINECOLOR 97 97 97
END
REQUIRES "([Buildings] = 1)"
END
With the "Buildings 0" layer, if I include the "REQUIRES" tag MapServer
will timeout. If I remove the "REQUIRES" tag everything runs smoothly.
I'm using PHP Mapscript 4.4.1. Before I upgraded (I think it was
Mapscript 4.0) this worked fine. So something has changed between then
and now with the "REQUIRES" algorithm.
Any ideas?
Thanks.
