Question

Unsure how to get this string to work correctly. Keeps making my page blank.

$imagefile = "http://mysite.ca/uploads/pages/large/$flyer['flyer_id']/$page['large_image']";
$imagedata = getimagesize($imagefile);
$imagewidth = $imagedata[0];
$imageheight = $imagedata[1];

I think it has something to do with both variables mixed in with regular text.

Answer 1

Do not embed the variables in your string:

$imagefile = "http://mysite.ca/uploads/pages/large/".$flyer['flyer_id']."/".$page['large_image'];

or wrap them in {}:

$imagefile = "http://mysite.ca/uploads/pages/large/{$flyer['flyer_id']}/{$page['large_image']}";

or remove the quotes around the array key (it is perfectly allowed inside a double-quoted string):

$imagefile = "http://mysite.ca/uploads/pages/large/$flyer[flyer_id]/$page[large_image]";
