spaces in front of form entry values

[tapping]

I have a form that submits to itself. After submiting the form, and if there is a user error, the form entry values are brought back with a space in front of the value. For example the first three digits of a ssn number bring back a space + 428.

Is there a way to keep the values from coming back with a space in front?

Use the Trim function, which trims white space.

In a form field, it might look something like this:
<cfoutput>
<input type="text" name="myField" value='#Trim(myValue)#"/>
</cfoutput>

HTH!

I am already using the trim function. There is still a space in front of the entries after the page reloads. It may have something to do with browsers.

Have you tested with IE and Firefox? If it happens with both browsers, that it probably is not a browser issue.

I've noticed CF places spaces sometimes when I'm calling user defined functions (UDF) and outputing the results to the screen instead of saving the value to a variable. Do you do any UDF processing of your form data?

I am not using many udf. Sample of form entry code below:

<input name="ssn1" type="text" id="ssn1" <cfif isdefined("form.ssn1")> value = "<cfoutput> #form.ssn1#</cfoutput>" <cfelse> value = "<cfoutput>***</cfoutput>"</cfif> onKeyUp ="validotherssn(this);" size="3" maxlength="3" align="left" onKeypress="if (event.keyCode < 48 || event.keyCode > 57 ) event.returnValue = false;" >
<input name="ssn2" type="text" id="ssn2" <cfif isdefined("form.ssn2")>value = "<cfoutput> #form.ssn2#</cfoutput>"<cfelse> value = "<cfoutput>**</cfoutput>" </cfif>
size="2" maxlength="2" onkeyup="validotherssn(this);" onKeypress="if (event.keyCode < 48 || event.keyCode > 57 ) event.returnValue = false;" >
<input name="ssn3" type="text" id="ssn3" <cfif isdefined("form.ssn3")>value = "<cfoutput> #form.ssn3#</cfoutput>" <cfelse> value = "<cfoutput>****</cfoutput>"</cfif> onKeyUp="validotherssn(this);" size="4" maxlength="4" onKeypress="if (event.keyCode < 48 || event.keyCode > 57 ) event.returnValue = false;" > </td>

If you are already doing a Trim( ), perhaps the "space" is some other non-printing character - a tab, cr, lf, etc. Do an Asc(Left(form.ssn1)) and see what the ASCII character is.

And you don't need all those <CFOUTPUT></CFOUTPUT> in your code. It clutters up the landscape and makes it difficult to read. <CFOUTPUT> at the beginning and </CFOUTPUT> at the end will do the job just fine.

I wrote the following code in the form. Return value was 52. I entered 425 as the value of ssn1.

<cfif isdefined("form.ssn1")><CFOUTPUT>#Asc(Left(form.ssn1,1))#</CFOUTPUT> </cfif>

[insuractive]

I think your problem is the space between <cfoutput> and your actual SSN

Try this:

"<cfoutput>#myVar#</cfoutput>"

instead of "<cfoutput> #myVar# </cfoutput>

Or better yet, surround the whole <td> with <cfoutput> so you don't have to keep reusing cfoutput blocks.

> <cfif isdefined("form.ssn1")><CFOUTPUT>#Asc(Left(form.ssn1,1))#</CFOUTPUT>
> </cfif>

Then the first character of form.ssn1 is a 4, not a space or other non-printable character. And I agree with insuractive, the space after <CFOUTPUT> is probably giving you problems.
