Validation without requiring entry

I created a fresh new data bridge backend for a database table a few months back. The project has sat until now. I was doing some final testing and I'm having an issue with form validation. It would appear that all of my form fields that I'm using validation for are requiring an entry on the insert page. I want to validate things like phone numbers for proper format IF there is an entry, but I don't want to REQUIRE an entry. It's fine if the field is left blank.

What determines whether the validation requires entry, vs checking for valid format only if there is an entry?

The "Server Validations" server behavior has a "Allow blank entry" option you can check to allow blank.

The form fields themselves have a "required" attribute you can remove to allow blanks.

Hmm... something else must be amiss then. They were all checked to "Allow Blank Entry". Just to be safe, I unchecked them and saved the changes. Then went back through and rechecked them all. It appears the last of the string stating "false" is what allows a blank entry, and according to the code that is what I have. However, it's still requiring entries on all those before proceeding.

"required" is no where to be found anywhere on the page.

Any other ideas? This is housed only locally so I don't have it up on a server I can point you to easily.

<?php
if ((isset($_POST["Insert"]) || isset($_POST["Insert_x"]))) {
$WAFV_Redirect = "".(htmlentities($_SERVER["PHP_SELF"], ENT_QUOTES)) ."?invalid=true";
$_SESSION['WAVT_tblmasterinsert_Errors'] = "";
if ($WAFV_Redirect == "") {
$WAFV_Redirect = $_SERVER["PHP_SELF"];
}
$WAFV_Errors = "";
$WAFV_Errors .= WAValidateDT((isset($_POST["dateinsert"])?$_POST["dateinsert"]:"") . "",true,"","","",false,"","","",false,1);
$WAFV_Errors .= WAValidateDT((isset($_POST["dateupdate"])?$_POST["dateupdate"]:"") . "",true,"","","",false,"","","",false,2);
$WAFV_Errors .= WAValidateDT((isset($_POST["datestart"])?$_POST["datestart"]:"") . "",true,"","","",false,"","","",false,3);
$WAFV_Errors .= WAValidateDT((isset($_POST["datestop"])?$_POST["datestop"]:"") . "",true,"","","",false,"","","",false,4);
$WAFV_Errors .= WAValidateNM((isset($_POST["weight"])?$_POST["weight"]:"") . "","","","",",.",false,5);
$WAFV_Errors .= WAValidateNM((isset($_POST["price"])?$_POST["price"]:"") . "","","","",",.",false,6);
$WAFV_Errors .= WAValidatePN((isset($_POST["phone"])?$_POST["phone"]:"") . "",false,true,false,7);
$WAFV_Errors .= WAValidatePN((isset($_POST["phone2"])?$_POST["phone2"]:"") . "",false,true,false,8);
$WAFV_Errors .= WAValidatePN((isset($_POST["fax"])?$_POST["fax"]:"") . "",false,true,false,9);
$WAFV_Errors .= WAValidatePN((isset($_POST["mobile"])?$_POST["mobile"]:"") . "",false,true,false,10);
$WAFV_Errors .= WAValidateEM((isset($_POST["email"])?$_POST["email"]:"") . "",false,11);

if ($WAFV_Errors != "") {
PostResult($WAFV_Redirect,$WAFV_Errors,"tblmasterinsert");
}
}
?>

That server code looks correct. I'd need to test it in action to debug further. Can you put it up on a live site?

Yeah I was afraid of that. Let me set up a live server and post...

OK Live version up. See PM for access.

You are using regular expression validation, but your regular expression doesn't allow a blank option. Can I get FTP access? I can try to update your .js files to account for this scenario.

See PM

It looks like you are using a space when there is no value in the field. The space is what is keeping it from allowing it to pass as blank.
