Title: Sold-out product filter - few lines for cup of coffee
Post by: mrbizzy on February 03, 2011, 13:30:17 PM

Hello Friends!
Idea: Put a checkbox on product browse page:

*when checked - show products that are out of stock
*when un-checked do not show out-of-stock products.

I can make it work for one page load by using form POST or GET.
I can even make it work for the whole session by using joomla sessions.

But i can't make it change the session value when unchecked.

So basically i need a few lines that will:

1. Set session to state "A" when checkbox is checked
2. Set session to state "B" when checkbox is un-checked

Also - after setting it to state "A" it should stay in that state and checkbox should appear as CHECKED until it is unchecked by the user.

The product sorting and filtering i will do myself.

I am open to any other solutions too.

It looks to me that this will only take a few lines of code but i can't find the correct approach.

I would love to buy you a cup of coffee if you help me out with this :)

Regards, Casper

You can use the $_SESSION global variable to record the state. Say $_SESSION['out_of_stock']=1;

You'll need to use 2 inputs...the checkbox and a hidden input to indicate that the user has clicked the checkbox (when a checkbox is unchecked, its value is not posted).

The show out of stock form:

Code Select

<?
$checked = '';
if($_SESSION['showoos']=='1') $checked=' checked ';
?>
<form name="showoos-form" method="post">
	<input type="checkbox" name="showoos" <?=$checked ?> onClick="document.showoos-form.submit" /> Show out of stock items
	<input type="hidden" name="oosclick" value="1" />
</form>

Then, place the following in a global file, probably the best would be /components/com_virtuemart/virtuemart.php:

Code Select

if($_POST['oosclick']=='1'){
	if($_POST['showoos']=='1'){
		$_SESSION['showoos']==1;
	}else{
		$_SESSION['showoos']==0;
	}
}

You'll probably want to use a few 'isset()' in there to stop any warnings on the front end.

Thank you for the effort. but something is missing/not-working here.
After submitting the form checkbox is unchecked again..
Also onClick does not work.. so i tried to add a submit button to test it.

Please keep in mind that when it comes to the coding i am not the brightest person around. So maybe there was something i should ADD in there which i did not understand i have to ????

I goofed the second piece of code...I did a boolean comparison instead of actually setting the variables. Change it to this:

Code Select

if($_POST['oosclick']=='1'){
	if($_POST['showoos']=='1'){
		$_SESSION['showoos']=1;
	}else{
		$_SESSION['showoos']=0;
	}
}

and the first bit of code javascript should have parens..

Code Select

<?
$checked = '';
if($_SESSION['showoos']=='1') $checked=' checked ';
?>
<form name="showoos-form" method="post">
	<input type="checkbox" name="showoos" <?=$checked ?> onClick="document.showoos-form.submit()" /> Show out of stock items
	<input type="hidden" name="oosclick" value="1" />
</form>
