html coder here, new and terrified * of php!!
aaaaaa!
i'm trying to bury a JS script to rotate a photo, in a page i
converted from html to php.
the conversion went well, it was to use a php session cookie to
stop the repeating of an embedded video file on a per session
basis; i amended the php code to display a still pic if the session
cookie value was nil.
worked fine.
thought I'd try integrating a tested and true JS image random
rotator script into the echo command, but the problem was the
syntax of the single quotes and double quotes needed in the
doc.write and variable sequences in the JS.
i tried escaping the double quotes (my echo used double quotes),
but to no avail.
here's the JS CODE i use in the tail end of my PHP. "picnumber" is
the variable holding the randomly assigned number that chooses the
picture.
any help much appreciated..

{ echo "
<script language='JavaScript1.2'>
<!-- begin
document.write(\"'<img src='images/swap/'+ picnumber +
'.jpg'>\");
// end -->
</script>
"; }

thanks
the single quote is actually necessary in JS when you're using
document.write to add strings in series (is it called "concatenating"
or something?). so the <img src...> statement was broken down into 3
seperate stings to be re-joined - all within the double-quote nested
doc.write stmt. my mistake was to leave the image path in single
quotes; instead I tried "escaped double quotes" to complete the image
path, like so,
{ echo "<script language='JavaScript1.2'>\n";
echo "<!-- begin \n";
echo "document.write('<img src=\"images/swap/' + picnumber
+'.jpg\"
width=\"320\" height=\"240\" border=\"0\" alt=\"Fitness Training
Image\">');\n";
echo "// end -->\n";
echo "</script>"; }
but no avail. still no pic shows up.
anyway. i get really confused with all the nested stuff and
single-double quotes. i may try that "heredoc" thing that Thomas
suggested. I'll need a couple of beers first. Friday night on
Javascript? Bad!
height and border. Only non-numeric data.
element attributes in that case, regardless of attribute value type.
2. You shouldn't use XHTML for web pages - it's not well supported by
some browser, not the least being IE 6 and 7.
HTML does NOT require quotes on numeric attributes.
Haha, where did you get that from? I've been building sites for ages
now with the XHTML doctype (transitional or strict, validates) and
never had any problems. I don't think I've ever had the desire or a
reason to use single quotes in HTML...

Try google. It's well documented.
