isset($_POST['submit']) not true

In a form I have replaced the submit button with the second line of code, as
follows (I wont go into the reasons here, to keep my question
straightforward)

echo "<form name=\"$this->formName\" id=\"$this->formName\" action=\"" .
$_SERVER['PHP_SELF'] . $theGETString . "\" method=\"POST\" >\n";
echo "<a href=\"javascript:document.forms['$this->formName'].submit();\"
class=\"button\" >Submit Form</a>\n";
echo "</form>\n";

The form APPEARS to get POSTed, however, in the form it is posting to, where
I have:

if (isset($_POST['submit'])) {
//this never gets executed!
}

My question is why not? Previously, if I created my submit button the
standard way:
echo "<input type=\"submit\" name=\"submit\" value=\"Submit Form\"
class=\"button\">

In my POSTed to form, it would get executed where if
(isset($_POST['submit'])) . Does anyone idea why I am unable to replace my
submit button here, or a workaround?

You took out the variable named 'submit' hence it is no longer set.

The work-around:
put this on your form
echo '<input type="hidden" name="submit" value="true">';

It places a form element called "submit" on your form, which you then later
check in the code to see if it was sent. Without the submit button it never
will be sent to server unless you have something to replace it with.

One thing I'd like to say that it's not generally a good idea to replace the
submit button with a javascript/link. Some people don't use javascript and
therefor they're unable to access your page if it relys on javascript. I
simply can't believe your situation really requires replacing the button
with a link until you explain why. I mean with css you can modify the
appearance of a button to look anything you like, even a link. Still not
satisfied? It can be an image as well... So why not? What's with the link?

How do I put it back in there without using the submit button itself?

See Kimmo's answer...<input type='hidden' name='submit' value='TRUE'>

You no longer have a button named submit posting to the other page, so
there is no longer a variable initialised in the $_POST array called
"submit". A way you can check if a form has been posted (assuming there
are any form values in the form) is to do the following check:

if(sizeof($_POST)) {
// do something
}

or to put a hidden field in the form (called eg "submit") and test for
that.

Ideally you should not use Javascript to submit a form at all as people
may have it disabled and then the form won't work at all. There are
obvious exceptions to this such as when creating an app for your own
purpose or for an Intranet where you can control what's going on in the
browsers.

I need to make the page appear exactly the same as a java applet which
resides in it. Therefore, I took out the botton images from the look and
feel package so that the page appears exactly like the applet. Enclosed
below is the page as rendered ( I assume this is what you are asking, yes?)
and the css file that it requires to render the buttons:

Oh, Sorry Kimmo -- I completely missed your first paragraph of your
response. But won't that make submit==true even if the reset button is then
hit? -Ike

No, because only hitting submit submit's the form. Hitting reset does not
send form data, it just rests the values.

Hmm.. okay, but why not

<div class="hbuttons">
<input type="reset" value="Reset Form" class="button" value="Reset Form"
onMouseOver="this.className='button_hover';"
onMouseOut="this.className='button';">
<input type="submit" name="submit" class="button" value="Submit Form"
onMouseOver="this.className='button_hover';"
onMouseOut="this.className='button';">
</div>

and

.hbuttons a, .hbuttons button{
display: block;
text-decoration: none;
font: 11px Arial;
color: black;
width: 140px;
height: 25px;
float: left;
display: inline;
margin-right: 8px;
background-image:url(backgroundbutton.gif);
background-repeat: no-repeat;
padding-top: 4px;
text-align:center;
border:none
}

..hbuttons a:hover, .hbuttons a#current, .hbuttons button_hover {
background-image:url(foregroundbutton.gif);
}

The only two changes would be that user with no javascript would
1) not get the hover-effect
2) still be able to submit the form.

The benefit of 2 exceeds the disadvantage of 1, so it would make sense to
use it.
