PHP is server-side. Dialog boxes are client-side. You can't do it in PHP.
You can do it in javascript - try comp.lang.javascript. You can even do
something close in HTML, but it's much harder.

This is a job for JavaScript in your browser. PHP doesn't have dialog
boxes because it runs on the server, not on the client.

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

Ah, the PHP-GTK stuff. I'd be happy if that worked well and was
available. But it's more than a years since the website was even updated
- and that was a comment a year after a comment that was itself a year
after any software was last released. And that had nothing for OS X in
which case <raspberry> to it.
So for all practical purposes PHP runs in the server, or possibly on
your machine at the command line.

Tim, GTK is not a browser. I'd still like to see "Pointed Head" tell me
which browsers implement PHP.
And please not I didn't indicate PHP can't run as a CLI on a client
machine. I specifically asked about browsers.

Andre, one way to avoid having to ask whether the person wants to
delete the record is to make deleting it a 2- or 3-action
process.
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.

Don't need to. Unlike you, I know what I'm talking about. But that's
normal for you - your trolling has made you persona non grata in several

.....or simply use an onClick to have a confirm message box pop up.

Exactly! 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.

There is exactly nothing in the OP to suggest that. In fact, it might very
well be possible that the OP was indeed working on client-side code. You
might also want to notice that they were grateful especially for that link:

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. Everything happens via
onclick events and ajax.

You need to be more precise with your terminology. There are no pages, in
particular not with server-side programming.
An (X)HTML document (as it can also be generated by a server-side script)
can contain more than one form, and they can be submitted separatedly.
Also, the target of a form submission can be – in HTML 4.01 Transitional or
XHTML 1.0 Transitional, or in XHTML 1.x with a user-defined DTD, to satisfy
validity constraints – another window (an iframe, a frame, or a tab), in
which case the document in the form's viewport would not change.
In this case, change is the purpose of the form, though. One *wants* to
display a document with a delete confirmation dialog *even if* the client-
side dialog *cannot* be displayed.
If the client-side dialog cannot be displayed (which is the premise of my
suggestion), then "AJAX" would not work either (keep in mind that the term
is not exactly a misnomer in the only regard that the "J" stands for
"JavaScript".)
However, my example is flawed as it is – due to oversimplification –
incomplete: If you would confirm the client-side dialog, the server-side
confirmation dialog would be displayed regardless.
A fix would be to set the submitted value of an `input' element to a certain
different value before submission so that the server side would not generate
the confirmation dialog again, e.g.:
<script type="text/javascript">
function confirmDelete(form)
{
if (window.confirm("Delete this item?"))
{
form.elements["confirmed"].value = "1";
return true;
}
return false;
}
</script>
<form action="delete-dialog.php"
onsubmit="return confirmDelete(this)"
method="POST">
<input type="hidden" name="confirmed" value="0">
<input type="submit" value="Delete">
</form>
Then, on the server-side, e.g.:
<?php
if ($_POST['confirmed'] !== '1')
{
/* this part should be done dynamically by the mentioned framework */
?>
<form action="delete-dialog.php"
method="POST">
<div>
<input type="hidden" name="confirmed" value="1">
<span>Delete this item?</span>
<input type="submit" value="Delete">
</div>
</form>
<?php
}
else
{
/* proceed with deletion */
}
?>
(I am using POST, and not GET, here so that one is less likely to cause
deletion accidentally when navigating the history. A good browser would ask
the user before submitting POST data again.)
More sophisticated approaches include using XHR (colloquially and falsely
called "AJAX") to request, retrieve and display a server generated
confirmation dialog instead of the rather crude, built-in one (BTDT). But
AISB, this would not work without client-side scripting, so it can be safely
excluded as a *fallback* for a server-side solution.

^^^^^^^^^^^^^^^^^^^^^^
Err, that's _client-side (traditional) solution_ (window.confirm), of
course.

IOW, your app cannot be used without client-side scripting, as "ajax"
requires that. With few exceptions, I would consider that bad software
design.

So what should I replace my 15000 lines of javaScript with then? Magic?

Just calling a spade a spade. Or, in your case, calling a stoopid troll
a stoopid troll - just like you've been called in so many newsgroups.

You should rewrite your application so that it works with and without
client-side scripting. That design approach is called graceful degradation.
It is not hard to do (see my example) if you start from the premise that
client-side scripting is not available, instead of the opposite. And 15000
LOCs is probably too much client-side script code. You might want to ask
questions about parts of your code where it is on-topic.

No I don't. This app requires JavaScript to be enabled in order to run.
Y'know, like most applications have a minimum configuration requirement?
Well this is one of those.
> That design approach is called graceful degradation.
So apps should be designed so they still run if someone removes the
processor from the computer? Were you always this mad?

I don't need to ask any questions at this time about my code, you rude
bastard. I expect it could be done with little or no JavaScript, but it
would be piss-poor experience for the user.
Now fuck off and take your shitty useless advice with you.

His basis is that you want to reach as many people as possible and a
certain percentage of them will turn off javascript. Now I ask, what is
that percentage? If you are selling something, how much added revenue
would be gained from having that percentage reach you versus the added
costs for writing AND DEBUGGING AND MAINTAINING a dual system.
Putting into google "percentage of people who turn off javascript" we
get from the very first link:
"According to data collected in 2007, 1.04% have it disabled in the EU,
and 3.05% have it disabled in the US."
So, between one and three percent turn off javascript. I call that no
BFD. I'll put a message in the script for the "page" that javascript is
required for this "page". It just doesn't pass the cost/benefit analysis.
(I, myself, am in the 97% of the US users).

Such global "statistics" are completely useless. What matters are your
own stats from your own website, nothing else.
> So, between one and three percent turn off javascript.
On one of the sites I maintan it's 8.5% for the current month and 12.6%
for the entire year until today. We're in the EU.

In my case, there is no "website", and so the stats are meaningless
anyway, although I appreciate what Shelly was doing. In my case, a
browser with JavaScript (I choose to use Safari), apache, a number of
PHP scripts, and SQLite are the components of my application. These all
come free under OS X, and since its the only platform I have and have an
interest in, that is the platform it runs on. To run it, the user
double-clicks an application icon just as they do with any app.
