[FORM FIELD VALIDATION]

poMMo uses a succint method for form field validation based on Smarty Validate.
The Smarty Validate README can be found in inc/lib/smarty-plugins/validate

Field validation rules and their error messages are defined in the PHP file (not .TPL).

The error messages are stored in the template variable $vMsg (array). If a field is found 
invalid, its error message is stored in the template variable $vErr (array).

To simplify validating form fields and processing the error messages, poMMo uses its
custom smarty function "fv".

The "fv" function accepts the following paramaters;
------------------------------------------------------

	validate  =  (field name)
		Activates validation on passed field name. Field name should match
		The name attribute of a form input.
		
	prepend  =  (error message prefix string)
		Sets the default string to be prepended to form validation error messages.
		Default: '' (blank)
		
	append  =  (error message postfix string)
		Sets the default string to be appended to form validation error messages.
		Default: '' (blank)
		
	message  =  (field name)
		If field name is found invalid, print the error message assosiated with
		the invalid field.
		
		NOTE; by default the message is wrapped with the prepend & append strings.
		If you would like to override the prepend + append strings for a particular
		error message, you can pass the "pre" and "post" parameters. e.g.
		
		{fv message="email" pre="<div>ERROR! <br />" post="</div>"}
		

Here is a typical example of using poMMo's {fv} function;
  REMEMBER; Field validation criteria (e.g. "isEmail", "notEmpty", "isPhone")
  	and error messages (e.g. "not a email", "cannot be empty", "not a phone number")
  	are assigned in the PHP file & are not controlled in the Smarty template files.
  	
--------------------------------------------
{* INITIALIZE FIELD VALIDATION *}
	{* Set default error message prefix & postfix *}
	{fv prepend='<span class="error">' append='</span>'}
	
	{* Activate validation on form fields *}
	{fv validate="email"}
	{fv validate="password"}
	{fv validate="captcha"}
	
<form method="post" action="">

<p>
{fv message="email"}
<input type="text" name="email" />
</p>

<p>
{fv message="password"}
<input type="text" name="password" />
</p>

<p>
{fv message="captcha" pre="Having Trouble? <a href='captcha_help.html'>click here</a>" post=""}
<input type="text" name="password" />
</p>

</form>
