Smarty

[tangfucius]

SmartyValidate is nice and powerful.
However here is one of the serious problem that I ran into:
Whenever I'm on a page with smartyvalidate, say the first time my input doesn't validate, I put in the correct data, and click on submit, my page validates the data and goes to the next page. Now if I click on the browser's "Back" button, it asks me if I want to re-submit the post data, I click on "Yes", I get a nasty form of "SmartyValidate validator not registered" errors.

Is there anyway to fix this???

Put some checks in your PHP logic before displaying the form... if the form is not registered, then do something about it before displaying.

[tangfucius]

that would require add the checks JUST for smartyvalidate in every single page that uses it, it can easily become a nightmare.

is that how you personally deal with this problem? is there better ways?

I test that the form is registered before the form is drawn. I don't recall that being a nightmare.

I ran into the same issue, and if you code your smarty setup according to the example in the documentation it is unavoidable. I now structure my code like this:

$smarty = new MySmarty();
if (empty($_POST)) {
setupSmarty($smarty);
/* do other stuff, forward to template form */
}
else {
setupSmarty($smarty);
if (is_valid($_POST)) {
/* process form */
}
else {
/* assign $_POST, etc */
}
}

function setupSmarty(& $smarty) {
if (is_registered_form('default')) {
SmartyValidate::connect($smarty);
}
else {
SmartyValidate::connect($smarty, true);
/* register validators */
}
}


Is this pretty much the way people are handling this?

Thanks,

Hi,

you call your "setupSmarty($smarty);" in the >if< and also in the >else< part of your if. So you can it also move it in front of the if-clause..

The duplication was intentional to demonstrate that:

1) The registration of validators has *nothing* to do with whether the PHP script was called with a POST HTTP request or a GET HTTP request

and

2) The lone example in the online documentation is not particularly realistic.

So are you guys going to provide a more useful "starting" example now?

i tried for a while to implement this SmartyValidate, but i couldn't work-around the "back button" problem...

unless this SmartyValidate is properly documented with a fully working example, i can't use it. i am a bit disappointed that this website advertises SmartyValidate that is 100% useless for 90% of all coders.

PS:
please prove me wrong.
