$image->size() misses height argument inside a function

[totoff]

Hi all,

I'm having some trouble to get $image->size() working properly inside a function. I have a function that accepts three arguments:

function renderSlides($sites = '', $field = "", $size = "")

Later on inside the function I would like to use this argument for cropping my images:

$slideimage = $slideimage->size($size);

Therefore I set $size in my template:

$size = "690,425";

If I check with var_dump(func_get_args()); it confirms I have a string:

var_dump(func_get_args(2));
[2]=> string(7) "690,425"

Nevertheless if I render the page, I get a PHP warning

Warning: Missing argument 2 for Pageimage::size()

and the image doesn't get cropped/sized properly.

Apologies in advance if this is a dumb question for a PHP pro, but what am I doing wrong here?

Thanks!

You're invoking the function with a single argument of the type "string" and the value "690,425", but size() needs two arguments/values, best of the type int. You cannot fake the comma between function arguments.

list($w, $h) = explode(",", $size, 2);
$w = (int) $w;
$h = (int) $h;
$slideimage = $slideimage->size($w, $h);
