First, the sound will work only in firefox.
So don't go bashing me for that.
I have it set up so that a shuffled array will be displayed any time the
page is loaded. Hopefully.
What I want to do is to ensure that item one in the menu list will match
what is in the iframe.
$_get[] relies on the values being transferred via a link.
At this point, no link has been clicked on to set the value.
So how do I properly set the intitial value?
<div id="menu1">
<?php
$numbers=range(1,60);
shuffle($numbers);
foreach ($numbers as $play) {
echo "<div class='item'>";
$year=$playme[$play][0];
$rank=$playme[$play][1];
$asong=$playme[$play][2];
$art=$playme[$play][3];
echo $asong;
echo "<br>";
echo $art;
echo "<br>";
echo $year;
echo " # ";
echo $rank;
echo "</div>";
$songid=$numbers[0]; << this reults in"1" always being piinted.
};
?>
</div>

Not so - it uses the query string -
https://en.wikipedia.org/wiki/Query_string - which may be passed via a
clickable link, or as part of a URL

<iframe id="x1" src="audiox1.php?a=foo&b=bar&c=baz" name="alpha"></iframe>
Simply pass the value(s) you need to utilise in the iframe

I tried this
<iframe id="x1" src="audiox1.php?asong=songid" name="alpha"></iframe>
Assigining songid as $songid=$play[0];
Retrieving value through
$number=$_GET["asong"];
echo $number;
Results in "songid" being printed.

Not surprisingly, because that is what you have set as the value for asong
in the iframe link. If you want to pass a value contained in a variable, you
should use the variable, not a string. Look closely at what you are doing
when calling the iframe.
<iframe id="x1" src="audiox1.php?asong=songid" name="alpha"></iframe>

If you copied the example as it was, you never get a value passed to the
frame, if you did make it as you should for appending a php value, then
the problem is that you haven't assigned a value.
Maybe something like http://www.w3schools.com/php could help you on the
way with the simple things.

That's up to you. How you choose default values to display when the page
is first loaded is always up to the developer.
However, if you have a consistency rule, it's probably best to ensure it
applies to the initial defaults as well as subsequent page loads.

That is as expected, you're setting the value of asong in the query
string to the text value songid.
Depending on how you're generating the string:
<iframe id="x1" src="audiox1.php?asong=songid" name="alpha"></iframe>
and assuming that $songid is a php variable containing the numeric songid
that you want to pass, you may wish to replace songid in the above
construction with one of:
' . $songid . '
$songid
{$songid}
I also suggest that you read
http://www.php.net/manual/en/language.types.string.php
very carefully. There are some very important comments there about what
happens inside different types of string literal depending on the quoting
methods used.

You may believe that the mistake was obvious, but you posted a valid url
to a non existent document. In such cases there is no "obvious" fix.

No need to quote the *values*, they are sent as text. Not sure what
you're doing with -alpha-, I assume it is a variable as well...

Sorry, HTML6, which introduces variables, is not widely supported yet.

The safe syntax is
echo "<iframe id=x1
src='audiox1.php?asong={$number}&name={$alpha}'></iframe>";
> No need to quote the *values*, they are sent as text.
Utter nonsense. Depending on the version of HTML and the attribute value,
attribute values MUST be quoted. The safe approach is to *always* quote
attribute values, it certainly is when attribute values or parts of those
are generated like here. Since double-quoting is more common than single-
quoting, double-quoting as it was done by the OP actually is the safe
approach.
You might have misread the original code, which is actually equivalent to
echo '<iframe id="x1" src="audiox1.php?asong='
. $number
. '" name="alpha"></iframe>';
if we assume that the line-break after “$number.'"” was accidental
originally or was inserted when you quoted the original code.
In particular, in your code the value of $alpha must be *URI-encoded* or the
URI-reference that is the attribute value is invalid or the entire HTML
fragment could become invalid (or code-injected) if $alpha contains space or
special characters. Other generated attribute values, unless it is certain
that code injection is impossible (for example with int values), SHOULD be
htmlspecialchars()'d.

Does it look like one? RTFM.

BULLSHIT!
target="alpha" is a valid attribute, it is not a value.
And there is no $ needed in the values section.

www.shut.the.fuk.up.stu.pid

if it does not exist, you get an error.

Actually, that is the safe *PHP* syntax (after the line-break is removed).
HTML requires another change:
echo "<iframe id=x1"
. " src='audiox1.php?asong={$number}&name={$alpha}'></iframe>";
AISB, conversion of ”&” to “&” or & can and should be done with
PHP's htmlentities() or htmlspecialchars(), respectively. And “echo” should
not be used like above, but like below:
<iframe id="x1" src="audiox1.php?asong=<?php echo $number;
?>&name=<?php echo htmlspecialchars($alpha); ?>"></iframe>
PHP 5.4 and PHP < 5.4 with corresponding php.ini configuration support
<iframe id="x1" src="audiox1.php?asong=<?= $number ?>&name=<?=
htmlspecialchars($alpha) ?>"></iframe>
and
<iframe id="x1" src="audiox1.php?asong=<%= $number %>&name=<%=
htmlspecialchars($alpha) %>"></iframe>
respectively. Usually you would use a template engine or the MVC pattern:
<iframe id="x1"
src="audiox1.php?asong=<?= $this->number ?>&name=<?=
$this->escape($this->alpha) ?>"></iframe>
This is explained and recommended in the first chapter of the PHP manual.

What is the “values section”?

You would use “target="alpha"” to display the result of navigation or form
submission in an “iframe” element with “name="alpha"” instead of the source
window, as the OP apparently intended. ISTM you need to brush up on your
HTML knowledge quite a bit.

What in the world are you talking about? This has nothing to do with
the -target- attribute. You said 'At least the first number is now
displayed.' so I thought you would eventually substitute "alpha" with
some variable content so I suggested it that way, also fixing your URL
by adding the '&' between them.

Ok, you're such an expert at fixing such obvious mistakes, what's the
correct url given that the following url gives a 404:
http://www.sined.co.uk/sined/m.use.html
Prove your answer is correct by telling us what appears at the correct
url.
Explain what makes the "obvious" answer so "obvious".

Norman, you've become confused by Richard's string quoting.
His php strings are single quoted and he uses double quotes for his html.
This means that php variable translation does not take place in the
strings.
In his initial example, name="alpha" was an attribute of the iframe, not
part of the query string of the src url.
This is why he has to replace songid with
'.$songid.'
instead of
$songid
Initially he said he was using this:
<iframe id="x1" src="audiox1.php?asong=songid" name="alpha"></iframe>
But he typically omitted to tell us whether this was in a heredoc or echo
with single quoted strings (or even a nowdoc).
In a heredoc, he could use $songid ( or even {$songid} ) but if it was an
echo with single quotes, he would need to use '.$songid.'
Subsequently he said '.$songid.' worked, so I deduce backwards from that
that richard was using single quoted php string with echo.
This is an example of classic richard, he feeds you half the problem and
the nature of the original problem only becomes clear after you've solved
for all possible variations and he's picked the solution that works. It
would be so much easier if he would learn to ask the right question, but
that's probably a lost cause now.
Mind you, I suspect so is his website. I still haven't worked out what
niche he expects to fill that isn't already fully covered by a
combination of you tube and wikipedia.

Yes, I actually see that now, but then again I usually keep my -id-
and -name- attributes together at the beginning of a tag. Is it required
no, but it sure does make for a bit of consistency when I'm looking for
bugs in the same typical places for the same types of data. It was a
misunderstanding on my part. As a general rule I shy away from doing a
lot of concatenation and "\" escaping as much as I possibly can. I also
try to sway others from it as well but, to each their own. It makes code
painful to debug.

Unless you have a death wish, I wouldn't hold your breath.This is the
