Dialog boxes are client-side. You can't do it in PHP. You can do it in javascript - try comp.lang.javascript.

Not necessarily.

Wrong, but the question is probably off-topic here regardless.

For example, you might require that they check 2 checkboxes and click a button. A person might accidently check one box and click the button, but it's quite unlikely that they'll check _both_ boxes for the same record by mistake.

And this is done in web applications using a client scripting language (such as JavaScript, not PHP). Whether or not PHP can run on the client in specialized environments is irrelevant. In most cases, it does run on the server and cannot generate confirmation dialog boxes.

For the reasons detailed below, `onClick' (or `onclick' in XHTML) is the
wrong event-handler attribute (and `click' is the wrong event) to use here.

You are still wrong about which language can be used where, and you really
do not know what JavaScript is.
However, more important to notice is that the drawback of a client-side only
solution in the client-server model – assuming this is the case here – is
that – rather obviously – it does not work without client-side support.
There is the NoScript extension, for example, to prevent client-side scripts
from running, as many people have used client-side scripting for rather
dubious purposes.
The client-side dialog – in fact, any client-side code – should augment a
server-side generated solution (to reduce the number of roundtrips to the
server, thus enhancing user experience and reducing server/network load);
with few exceptions, it should not replace it. This can be done easily, for
example:
<form action="delete-dialog.php"
onsubmit="return window.confirm('Delete?')">
<input type="submit" value="Delete">
</form>
The best solution regarding this approach is a server-side framework which
provides the classes to generate the forms (here: both for submitting the
deletion request and confirming it) and the client-side code, so that the
data only needs to be maintained in one place.

Wouldn't you use onsubmit only if you are submitting the entire page?
The onclick allows you to confirm the deletion, send off an AJAX
request, and still stay on the page.

Yes. In my app I never submit any forms at all.

With few exceptions, I would consider that bad software design. PointedEars -- Prototype.js was written by people who don't know javascript for people who don't know javascript.
