Smarty

[MrNiceguyD]

Does anyone has an (simple)example of how to use SmartyValidate with a multipage form? I am using the latest versions of SmartyValidate(2.4.0) and Smarty(2.6.9). I am using SmartyValidate on to validate all forms and it works great, i just cant figure out how to get multi-page forms to work.
Any help would be greatly appreciated.

Best regards,

Davy

1) put your form across multiple templates (each page)

2) on each page you have a validator, set the page number:
{validate page="1" ...}

3) prior to displaying a page, set the SmartyValidate::set_page('1')

So for example:

SmartyValidate::set_page('1');
$smarty->display('form_p1.tpl');

// do validation cycle for page 1, then

SmartyValidate::set_page('2');
$smarty->display('form_p2.tpl');

// etc...

Thanks for you quick reply

I have two templates and added the page attribute to the validators like {validate page="1" ...} etc. And in my php code i have done SmartyValidate::set_page('1') and SmartyValidate::set_page('1') prior to displaying the form but i stil get 2 forms on my page. How would u let the form know on what page you are and which form to validate ($_GET or $_SESSION)? btw is it okay to use:

$validator->set_page('2'); instead of SmartyValidate::set_page('1') , ofcourse after creating an instance of the SmaryValidate class first?

Here is my code:

[php:1:657ebe639d]<?php
session_start();

require('../../lib/demo/setup.php');
require('../../lib/Smarty/SmartyValidate.class.php');

$smarty =& new Smarty_Demo();
$validator =& new SmartyValidate();

if(empty($_POST)) {
// new form, we (re)set the session data
$validator->connect($smarty, true);

// register our validators
$validator->register_validator('username', 'UserName', 'notEmpty', false, false, 'trim');
$validator->register_validator('password', 'password:password2', 'isEqual');
// display form
$validator->set_page('1');
$smarty->display('signup_form1.tpl');

// register our validators
$validator->register_validator('firstname', 'FirstName', 'notEmpty', false, false, 'trim');
$validator->register_validator('lastname', 'LastName', 'notEmpty', false, false, 'trim');
$validator->register_validator('emailempty', 'Email', 'notEmpty', false, false, 'trim');
$validator->register_validator('emailvalid', 'Email', 'isEmail', false, false, 'trim');
$validator->register_validator('phone', 'Phone', 'isNumber', true, false, 'trim');
// display form
$validator->set_page('2');
$smarty->display('signup_form2.tpl');
} else {
// validate after a POST
$validator->connect($smarty);
if($validator->is_valid($_POST)) {
// no errors, done with SmartyValidate
$validator->disconnect();
$smarty->display('success.tpl');
} else {
// error, redraw the form
$smarty->assign($_POST);
$validator->set_page('1');
$smarty->display('signup_form1.tpl');
}
}
?>[/php:1:657ebe639d]

I know i am probably forgetting something here.. since it isnt working?
Thanks for your time

They both display because you are displaying both forms in your logic. You need to display page 1 first, than after that validates, display page 2, etc. Something like (untested):

[php:1:13a63ee414]$smarty =& new Smarty;

switch($_REQUEST['page']) {
case "1":
// coming from first form page
SmartyValidate::connect($smarty);
if(SmartyValidate::is_valid($_POST)) {
// first page valid, display second page
SmartyValidate::set_page('2');
$smarty->display('form_p2.tpl');
} else {
// error, redraw first page
$smarty->assign($_POST);
$smarty->display('form_p1.tpl');
}
break;
case "2":
// coming from second page
SmartyValidate::connect($smarty);
if($smarty->is_valid($_POST)) {
// second page is valid, we're done
SmartyValidate::disconnect();
$smarty->display('main_menu.tpl');
} else {
// error on second page, redraw
$smarty->assign($_POST);
$smarty->display('form_p2.tpl');
}
break;
default:
// first time in, or new form
SmartyValidate::connect($smarty,true);
// register all validators
$validator->register_validator('username', 'UserName', 'notEmpty', false, false, 'trim');
$validator->register_validator('password', 'password:password2', 'isEqual');
$validator->register_validator('firstname', 'FirstName', 'notEmpty', false, false, 'trim');
$validator->register_validator('lastname', 'LastName', 'notEmpty', false, false, 'trim');
$validator->register_validator('emailempty', 'Email', 'notEmpty', false, false, 'trim');
$validator->register_validator('emailvalid', 'Email', 'isEmail', false, false, 'trim');
$validator->register_validator('phone', 'Phone', 'isNumber', true, false, 'trim');
// set page, draw form
SmartyValidate::set_page('1');
$smarty->display('form_p1.tpl');
break;
}[/php:1:13a63ee414]

Notice you need to keep track of what page you are on in the form:

Thanks again

How stupid i should`ve seen that lol. I gues its monday...
I have modified my code but i get errors:

Warning: Smarty error: validate: validator id 'username' is not registered. in C:\Projects\davy\lib\Smarty\Smarty.class.php on line 1088

But i do have {validate page="1" id="username" message="<div class=\"error\">User Name Cannot Be Empty</div>"} in my first template.

I cleared my sessions in my browser and my cache, any idea`s?

[php:1:ccd20b54b2]<?php
session_start();

require('../../lib/demo/setup.php');
require('../../lib/Smarty/SmartyValidate.class.php');

$smarty =& new Smarty_Demo();
$validator =& new SmartyValidate();

switch ($_POST['page']) {
case "1":
// coming from first form page
$validator->connect($smarty);

// register our validators
$validator->set_page('1');
$validator->register_validator('username', 'UserName', 'notEmpty', false, false, 'trim');
$validator->register_validator('password', 'password:password2', 'isEqual');

if($validator->is_valid($_POST)) {
// no errors, show page 2
$validator->set_page('2');
$smarty->display('signup_form2.tpl');
} else {
// error, redraw the form
$smarty->assign($_POST);
$smarty->display('signup_form1.tpl');
}
break;

case "2":
// coming from second form page
$validator->connect($smarty);

// register our validators
$validator->set_page('2');
$validator->register_validator('firstname', 'FirstName', 'notEmpty', false, false, 'trim');
$validator->register_validator('lastname', 'LastName', 'notEmpty', false, false, 'trim');
$validator->register_validator('emailempty', 'Email', 'notEmpty', false, false, 'trim');
$validator->register_validator('emailvalid', 'Email', 'isEmail', false, false, 'trim');
$validator->register_validator('phone', 'Phone', 'isNumber', true, false, 'trim');

if($validator->is_valid($_POST)) {
// no errors, done with SmartyValidate
$validator->disconnect();
$smarty->display('success.tpl');
} else {
// error, redraw the form
$smarty->assign($_POST);
$smarty->display('signup_form2.tpl');
}
break;

default:
// first time in, or new form
$validator->connect($smarty, true);

// register our validators
$validator->set_page('1');
$validator->register_validator('username', 'UserName', 'notEmpty', false, false, 'trim');
$validator->register_validator('password', 'password:password2', 'isEqual');

// display form
$smarty->display('signup_form1.tpl');
break;
}

Try registering all your validators only once, like in the example I gave. You certainly don't want to execute register_validator() inside of your validation cycle.

Thanks again Monte,

It works great now
