#21916 — values won't transfer

www.mroldies.net/index.php

this is not the same page as the home page as that is still active for the
moment.

I am trying to pass the value in the url to the iframe.
No matter what I try, it won't.
I had to use the \" in order for the link to show properly.
The iframe is named "show".

My thinking is that the javascript has somehow destroyed that.
Queswtion is, how do I make it work so that the value "tune" will pass
properly?






	  <div style="float:left; width:5in; height:6in; overflow:auto;
border:solid 2px #00ff00; padding:10px;">
      <ol>
        <?php
		$numbers=range(1,200);
		shuffle($numbers);
		
		foreach($numbers as $play) {

		$htp="http://mroldies.net/index.php?tune=".$play." target=\"show\"";

		echo "<li>";
		$asong=$playme[$play][4];
		echo "<a class='aplay' href='".$htp."'
data-src='http://mroldies.net/200/";
		echo $asong;
		echo ".mp3'>";
	    echo $playme[$play][2]." - ".$playme[$play][0]." #
".$playme[$play][1];
		echo "<br>";
		echo $playme[$play][3];
		echo "</a>";
		
		echo "</li>\n";
		}
		
		?>
      </ol>
	  </div>

But you reference that in your code below. So that is what will be
used, not some other version.

What javascript? You haven't shown any.

Is the above part of your new mroldies.net file? If so, why are you
loading another copy of it into an iframe within it? And otherwise,
what are you doing inside the iframe to try to obtain the value of
tune?

The above didn't load anything into the iframe when I tried it; I
haven't looked into why. Personally I use open(), write(), and close()
to write an html string into an iframe, which may not be the best way
to do it but works well enough for me.

You quoting is wrong.  In general, if you don't know exactly why you
needed some construct such as the \", it's better to go a read up on
that area.  It's almost impossible to program by trial and error.

I think your question is purely a PHP one, so I've set followups
accordingly.

  If $play is, say, 42, the result of this will be:

  <a class='aplay' href='http://mroldies.net/index.php?tune=42 target="show"'

Can you see how the show attribute is incorrectly inside the
single-quoted href attribute?

Yes - because the string is already delimited with double quotes.

What JavaScript? There is no JavaScript in the code you present here.

Don't put target="show" inside the href attribute. Check the created
HTML - you will hopefully see the error.

You define $htp as:

$htp="http://mroldies.net/index.php?tune=".$play." target=\"show\"";

But then you write:

echo "<a class='aplay' href='".$htp."' ...

So - expand this - it will become:

<a class='aplay'
href='http://mroldies.net/index.php?tune=$play target="show"'

Try to think about the problem - step by step. And not just put together
a bunch of code without caring for details!

If you put just the anchor attributes line by line the code also becomes
much easier to read. Also note that you can enclose double quotes in
single quotes (and vice versa) and there is absolutely no need to define
a separate variable to use an array value.

And finally: Either you have to make sure, that $playme[$play][3] does
not contain any "HTML stuff" or use htmlspecialchars() to encode/escape
special characters so they will be displayed properly.

Here a proposal how it should work (not checked - there may be typos):

<?php
foreach($numbers as $play) {
  echo '<li>';
  echo '<a';
  echo ' class="aplay"';
  echo ' href="http://mroldies.net/index.php?tune='.$play.'"';
  echo ' target="show"';
  echo ' data-src="http://mroldies.net/200/'.$playme[$play][4];
  echo '">';
  echo htmlspecialchars($playme[$play][3]);
  echo '</a>';
  echo '</li>';
}
?>

F'Up to comp.lang.php since this has nothing to do with JavaScript at all.
