Return an array from PHP function to Smarty
At the risk of self-embarrassment, could anyone tell me how to use return here:
function dayCount() {
for ($dayBegin = 1; $dayBegin < 32; $dayBegin++)
{
"<option value=\"".$dayBegin."\">".$dayBegin."</option>";
}
}
My issue is that I am passing this function to Smarty via
$dayCount = dayCount();
$smarty->assign('dayCount', $dayCount);
and
{$dayCount}
but instead the HTM开发者_如何学JAVAL is going straight to the buffer, right before <html> (thanks Hamish), not inside the HTML element I want.
Any help on this?
You need to build up the return statement
function dayCount() {
$return = array();
for ($dayBegin = 1; $dayBegin < 32; $dayBegin++)
{
$return[] = "<option value=\"".$dayBegin."\">".$dayBegin."</option>";
}
return $return;
}
Although this is building up an array like you asked. When outputting it, you would need to implode it.
implode('', $dayCount);
Or otherwise, build up a string instead of an array.
