If you your own custom build then are you sure it's not a case of multiple versions of REGEX on the same system? That used to be a problem in the old days with PHP's local copy of regex conflicting with the system regex, but I don't think that is a problem any more though.<div>

Well, that’s not good is it. Hmmm… I ran a quick test here using this<br>
mapfile:<br>
<br>
MAP<br>
<br>

<br>

<br>
END<br>
<br>
END<br>
<br>
This is against 6.0 latest trunk although I don’t think there have been<br>
any changes in that area…<br>
<br>
I can run something like:<br>
<br>
mapserv -nh "QUERY_STRING=map=test.map&<u></u>mode=map&area=500000000" > test.png<br>
<br>
If ‘area’ parameter is provided as a non-double then the substitution<br>
isn’t done. I believe the substitution validation errors fail silently.<br>
This example works, how different is what you’re doing?<br>

Thanks Steve.<br>
<br>
Tried the following regular expression<br>

"[-+]?[0-9]*\.?[0-9]+".<br>
<br>
For which the internal server error is coming from Apache. No error<br>

EXPRESSION<br>
<br>
Hi,<br>
<br>
I need to compare one attribute from database table in "EXPRESSION"<br>
(under "LAYER") with six different values passed as Variable<br>
Substitution for coloring the layer.<br>
<br>
I did added validation for those variables in the map file, but for some<br>
reason I am getting the below error.<br>
<br></div>
*msValidateParameter(): Regular expression error. Parameter pattern<br>
validation failed.*<br>
<br>
*msEvalRegex(): Regular expression error. String failed expression test.*<br>
<br>
*msValidateParameter(): Regular expression error. Parameter pattern<br>
validation failed.*<div><div><br>
<br>
Could anyone help me with where I am wrong? Below is the map file<br>
content for this layer.<br>
<br>
All the six variables would be numbers (may be a decimal number), Is my<br>
regular expression correct?<br>
<br>
WEB<br>
<br>
VALIDATION<br>
<br>
value_one "^[\d+(\.\d)]*$"<br>
