when debugging asp pages it can be very useful to see exactly what data is being sent when a form is posted. for that reason, i decided to create a handy little function that will display all of the form variable names and values. this function, formdatadump() has the following definition:
sub formdatadump(bolshowoutput, bolendpageexecution)
these two input parameters are boolean values. bolshowoutput, if true, will dump out the form field names and values for all to see. this has the effect of making your html page uglier and harder to read – therefore, if you are testing on a live site, you should set this value to false, in which case the form field names and values will be outputted inside of an html comment tag (<!– form field names and values –>), so that they can only be seen via a view/source.
the second parameter, bolendpageexecution, determines whether or not a response.end is issued in the formdatadump() function. response.end, if issued, ends the processing of the asp page.
below you will find the complete code for the formdatadump() function.
sub formdatadump(bolshowoutput, bolendpageexecution)
dim sitem
what linebreak character do we need to use?
dim strlinebreak
if bolshowoutput then
we are showing the output, so set the line break character
to the html line breaking character
strlinebreak = "<br>"
else
we are nesting the data dump in an html comment block, so
use the carraige return instead of <br>
also start the html comment block
strlinebreak = vbcrlf
response.write("<!–" & strlinebreak)
end if
display the request.form collection
response.write("displaying request.form collection" & strlinebreak)
for each sitem in request.form
response.write(sitem)
response.write(" – [" & request.form(sitem) & "]" & strlinebreak)
next
display the request.querystring collection
response.write(strlinebreak & strlinebreak)
response.write("displaying request.querystring collection" & strlinebreak)
for each sitem in request.querystring
response.write(sitem)
response.write(" – [" & request.querystring(sitem) & "]" & strlinebreak)
next
if we are wanting to hide the output, display the closing
html comment tag
if not bolshowoutput then response.write(strlinebreak & "–>")
end page execution if needed
if bolendpageexecution then response.end
end sub
thats it! to call the function, simply use:
call formdatadump(trueorfalse, trueorfalse)
