How do I validate a textarea type field within a CFFORM? 3

[ashw]

Hi I am new at this, so please help.
I have defined this:
<textarea name=&quot;weblinkdescription&quot;
rows=&quot;6&quot; cols=&quot;60&quot;></textarea>
within a <CFFORM></CFFORM> tag
How do I validate this textarea field so that an alert message should pop when the field is left blank, prompting, the user to enter the description.
Looking forward to yor help,
Regards ashw

Your best bet will be to use Javascript. Hope that helps

yes.u will need to write a javascript above ur codes
urform is your form name
place tis script ard the head
<script language=&quot;javascript&quot;>
function check()(
if(document.urform.weblinkdescription.value.length==&quot;0&quot; || document.urform.weblinkdescription.value.charAt(0)==&quot; &quot{
alert(&quot;Enter web link description!!&quot
document.urform.weblinkdescription.focus();
return false;}
}
</script>

finally at your submit button add this onClick=&quot;return check();&quot;

Dear Bondark,
Thanks so much for ur help. I wrote the following code in the head:

<script language=&quot;javascript&quot;>
function check()(
if(document.NewWebLink.weblinkdescription.value.length==&quot;&quot; ||
document.NewWebLink.weblinkdescription.value.charAt(0)==&quot;&quot{
alert(&quot;Enter website description!&quot
document.NewWebLink.weblinkdescription.focus();
return false;}
}

and then above body
onsubmit=&quot;return check()&quot;>

but it shows the following error

ODBC Error Code = S1000 (General error)
[Microsoft][ODBC Microsoft Access Driver] Field 'tblweblink.weblinkDescription' cannot be a zero-length string.

The error occurred while processing an element with a general identifier of (CFQUERY), occupying document position (9:1) to (9:44).

Please help,
regards,
ashw

You have two options either open the database click on the field that is given in the error and set it to allow zero length strings, or you have to check that field and make sure it is not zero length. If you don't know how to check for that in the script let me know and I will write it out.

perharps u set its default to not null?

 

[Wes98765]

Yes that would work but depending on the type of data contained in this feild that could cause extra work. He would most likely have to check conditions to exclude the default value.
