From: Carlton Whitehead on 4 Aug 2010 08:33 That is definitely calling out for a loop. When I scan down the lines of code, the only part I see changing is the x after $pic_x. You could make an array with all of the picture details and then replace all of that repeated code with a loop like so: $pics = array('my_first_picture.jpg', 'my_second_picture.jpg', 'etcetera.jpg'); foreach ($pics as $pic) { if (trim($pic) <> "") { echo "<div class='proddetailpics'><a href='#' class='color_thumb'> <img src='/imagedir/$pic' alt='$itemgroup $itemsubgroup' width='60' height='60' onclick=MM_swapImage(' prodimage','','/imagedir/$pic',0) border='0' /></a></div>"; } } For the next step, you can just replace all those single quotes in your HTML with escaped double quotes like so: if (trim($pic) <> "") { echo "<div class=proddetailpics\"><a href=\"#\" class=\"color_thumb\"> <img src=\"/imagedir/$pic\" alt=\"$itemgroup $itemsubgroup\" width=\"60\" height=\"60\" onclick=MM_swapImage(\" prodimage\",\"\",\"/imagedir/$pic\",0) border=\"0\" /></a></div>"; } As others have pointed out, you might want to use single quotes for the PHP value being passed to echo. That would save you from having to escape the HTML double quotes, but then you can't include $variables inside of single quoted strings (you have to concatenate them separately). Pick your poison. The PHP documentation on strings is pretty good, and it couldn't hurt to have a look: http://php.net/manual/en/language.types.string.php Carlton Whitehead On Tue, Aug 3, 2010 at 3:44 PM, Rick Dwyer <rpdwyer(a)earthlink.net> wrote: > > On Aug 3, 2010, at 3:36 PM, Ashley Sheridan wrote: > > > On Tue, 2010-08-03 at 15:32 -0400, Rick Dwyer wrote: > >> > >> On Aug 3, 2010, at 3:15 PM, Sebastian Ewert wrote: > >> > >> > Ashley Sheridan wrote: > >> >> On Tue, 2010-08-03 at 15:00 -0400, Rick Dwyer wrote: > >> >> > >> >>> On Aug 3, 2010, at 2:47 PM, Sebastian Ewert wrote: > >> >>> > >> >>>> Rick Dwyer wrote: > >> >>>>> Hello List. > >> >>>>> > >> >>>>> In the Alt section of the IMG tag below, the variable $myitem has > a value of "Who's There". > >> >>>>> > >> >>>>> echo "<div class='myclass'><a href='#' class='color_thumb'> <img > src='/itemimages/$mypic' alt='$myitem' width='60' .... > >> >>>>> > >> >>>>> When running through W3C validator, the line errors out because of > the " ' " in "Who's". > >> >>>>> I tried: > >> >>>>> $myitem=(htmlentities($myitem)); > >> >>>>> > >> >>>>> But this has no affect on "Who's". > >> >>>>> > >> >>>>> What's the best way to code this portion so the apostrophe is > handled correctly? > >> >>>>> > >> >>>>> > >> >>>>> TIA, > >> >>>>> > >> >>>>> --Rick > >> >>>>> > >> >>>>> > >> >>>>> > >> >>>>> > >> >>>> Use it > >> >>>> > >> >>>> > >> >>>> echo '<div class="myclass"><a href="#" class="color_thumb"> <img > >> >>>> src="/itemimages/'.$mypic.'" alt="'.$myitem.'" width="60" ...' > >> >>> > >> >>> Thanks Sebastian. > >> >>> > >> >>> In the above, what is the function of the period in front of > $myitem? > >> >>> > >> >>> --Rick > >> >>> > >> >>> > >> >> > >> >> > >> >> It is a string concatenation in PHP.
