I'm having trouble using the <CFINPUT TYPE="TEXT" REQUIRED="Yes"> tag. When I load the form template in my browser, and purposefully leave the TEXT input blank it doesn't throw an error message like it should.

Here is the form code:
Code: 
<CFFORM ACTION="testaction.cfm" METHOD="POST"> 

Please Enter Your Name<BR>
<CFINPUT 
	TYPE="text"
	NAME="Contact"
	SIZE="20"
	REQUIRED="Yes"
	MESSAGE="Name is required!">

<INPUT TYPE="submit" VALUE="Submit">

</CFFORM>

Here is the action code:
Code: 
<CFOUTPUT>

Thanks for your input #form.Contact#!

</CFOUTPUT>

The form is located at
I'm going crazy trying to figure this out. Does anyone have any ideas?

Try this:

I just tried it and it worked:

----------------------------------
<CFFORM ACTION="testaction.cfm" METHOD="POST" NAME="submit">

Please Enter Your Name<BR>



<CFINPUT TYPE="text" NAME="Contact" SIZE="20" REQUIRED="Yes" MESSAGE="Name is required!">

<INPUT TYPE="submit" VALUE="Submit">

</CFFORM>
-------------------------------------

I just added a name to the form.

Yes, but what happens when you do not add a name to the form? Do you get an error message? That is what it is suppose to do, but doesn't.

Great solution bomboy! Works great, and I will probably use that from now on.

However, I would like to know why my original coding won't work. Does anyone know why it doesn't work? It should. Sure would cut down on the amount of coding required if it did work.

try adding 'value = "" ' and see what happens. It's a swing in the dark, like I said I don't use <cfform> stuff. This may force an empty string to start with. not sure.

Thanks for attempting the swing bombboy, but unfortunately it missed. Anyone else care to take a swing at it?

have you got scripting turned on in your browser, as the code that you posted at the start works for me on our server.

CFMX 6.1, IE 6, win XP SP 2

Have you got a error in the bottom left hand corner of your browser window?

Hope this helps!

Yes, scripting is turned on. And no...there is not any error anywhere.

I copied and pasted exactly what was posted and it works fine. If I view source I get this

<SCRIPT LANGUAGE="JavaScript" TYPE="text/javascript">
<!--

function  _CF_checksubmit(_CF_this)
{
	if  (!_CF_hasValue(_CF_this.Contact, "TEXT" ))
	{

		{

	}

	return true;
}

It's wierd. If I copy the CF code and run it, it works. If I view source and copy/paste (from RSedlacek's link), it does just what RSedlacek is describing.



Hope This Helps!

Good point.
I ran the link and when you submit it you will get an error on the page.

line: 14
Error: object expected

line 14 is:
if (!_CF_hasValue(_CF_this.Contact, "TEXT" ))

I think _CF_hasValue() is coming from the .js file, I don't se it mentioned elsewhere. maybe it can't find the file. check for it in the scripts folder under cfide maybe.

My service provider fixed it by doing the following:

"It appears that you were using java script for the form validation and calling it from the cfide directory.
What I did was create a virtual directory called CFIDE and mapped it to the cfide in the webroot of default website."

The java script was automatically generated from the use of CF tags. CF uses tags to call the jscript.

Thanks for posting the solution.
