response.write asp - 4/27/2003 5:43:50
Here is what Im trying to do
If statement to response.write " Email" if the field
<%=FP_FieldVal(fp_rs," Email" )%>
contains an address. Blank otherwise.
Heres the tricky bit. This is then a mailto: link.
I just cant get the syntax right.
Can anyone help?
This is what I have so far
<%
if FP_FieldVal(fp_rs," Email" ) = " " then
response.write " "
else
response.write <a href=" mailto:FP_FieldVal(fp_rs," Email" )" >Email</a>
end if
%>
Syntax error

The mailto: link works well. Only problem is that " Email" is displayed even where the field is empty.
Makes me wonder whether
if FP_Field(fp_rs," Email" ) = " " then
response.write " "
is correct. Seems to be.
Any better suggestions anyone?
Thanks

It depends whats in the database, perhaps there are spaces?
if Trim(FP_Field(fp_rs," Email" )) = " " then
response.write " "
To do quotes in asp, you have to be careful to include the right amount.
Consider this :
response.write " Bob said " Hello"
You have 3 quotes. 1 Represents the opening of a string. The 2nd, part of the string is a quote, but still part of the string.
However, vb interprets it as the close of a sting (matched pair) and would generate an error. " Expected end of statement "
Now consider this :
response.write " Bob said " " Hello" "
With 2 quotes, vb now interprets this as a single quote.
However, as there are a total of 5 quotes, an error " Unterminated string constant " will be generated as the string is not closed.
This would be a valid string :
response.write " Bob said " " Hello" " "
Add some html :
response.write " Bob said <font size=" " 10" " face=" " verdana" " >" " Hello" " "
Add a variable:
response.write " Bob said <font size=" " " &Fontsize&" " " face=" " verdana" " >" " Hello" " "

You are using if FP_Field(fp_rs," Email" ) and not if FP_FieldVal(fp_rs," Email" ) ?
