Re: Custom Fields

Toolbelt and Toolkit have a way to tie into Miva's default validation.

The way you are doing it now won't work, because even if it is blank, Miva's validation for the form will ignore it.

You're better off validating that field using JavaScript before the form is submitted.

Re: Custom Fields

Here's a little page that does what you want I think. It executes the edit when the page is submitted using the onsubmit in the <form tag:
<!DOCTYPE html>
<html>
<head>
<title></title>
<script type="text/javascript">
function trimString(val) {
var valu = val;
valu = rtrimString(valu); //trim trailing spaces
valu = ltrimString(valu); //trim leading spaces
return valu; //return trimed variable
}
function rtrimString(val) //remove trailing spaces
{
var valu = val;
while (valu.charAt(valu.length - 1) == " ") //trim all trailing spaces
{
valu = valu.substr(0,valu.length - 1);
}
return valu;
}
function ltrimString(val) //remove leading spaces
{
var valu = val;
while (valu.charAt(0) == " ") //trim all leading spaces
{
valu = valu.substr(1);
}
return valu;
}

function edit_bike(obj) {
var bike = trimString(obj.bike_field.value);
if (bike == "") {
obj.bike_field.style.background="red";
obj.bike_field.focus();
alert("please enter a value");
return false;
}
alert("OK");
return true;
}
</script>
</head>
<body>
<form action="" onsubmit="return edit_bike(this)">
<input type="text" name="bike_field" />
<input type="submit" value="continue" >
</form>
</body>
</html>

Re: Custom Fields

You could always do the following:

Code:

<mvt:if expr="s.request_method EQ 'POST' AND ISNULL g.YearMakeModel">
          <mvt:assign name="g.YearMakeModel_Invalid" VALUE = "'1'" />
<mvt:else>
           <mvt:assign name="g.YearMakeModel_Invalid" VALUE = "'0'" />
</mvt:if>

or if you understand the logic clearly you could do

Code:


<mvt:assign name="g.YearMakeModel_Invalid" VALUE = "s.request_method EQ 'POST' AND ISNULL g.YearMakeModel" />

That should work as desired.
