maintaining checkbox value between pages

[lara8]

hi, can anybody help me with the following?
I have generated a script that shows a number of images on a page. Under each image a checkbox (default not checked) is shown, of which multiple checkboxes can be checked. Now I also have "Previous 1 2 Next" buttons on this page. When moving to the Next page, I don't want to lose the information of the checkboxes that were checked on the former page. How can I do this when the "Previous 1 2 Next" buttons are a HTML-hyperlink (so not the submit button of the form with the checkboxes)????

Just add a flag to the hyperlinks:

if ($checkbox == "checked") {
$hyperlink .= "&checkbox=checked";
}

if prev/next are normal links then you will have to call javascript when onclick occurs and add checked checkboxes to the link parameters. otherwise you will loose them.

Hello lara,

Your "prev" and "next" links may be not a simply html hyperlink...

It must be a "inteligent" link. So you'll need the javascript code to work.

you must code some like:

<script language=javascript>

function moveto(direction) {
//direction = prev or next, you determine
baseurl = "move.php&direct="+direction;
for (i=0;i<document.yourform.length;i++)
{
if (document.yourform.elements.type == "checkbox")
if (document.yourform.elements.checked)
baseurl = baseurl + "&" + document.yourform.elements.name + "=" + document.yourform.elements.value;
}
location.href=baseurl;
}

</script>


<a href="JavaScript:moveto('prev')">Prev</a> or <a href="JavaScript:moveto('next')">Next</a>


It may work... I don't test, but sounds good

If I am right (50/50 chance) I think you should use cookies or track_vars variables ...read up on that maybe? 🙂
