Hi,

Could someone please explain to me why the following code:

{let options=hash('all', 'All weekdays', 1, 'Monday', 2, 'Tuesday', 3, 'Wednesday', 4, 'Thursday', 5, 'Friday', 6, 'Saturday', 0, 'Sunday')}
	{let selected_option='all'}
	        {section name=Child loop=$options}
			{$:key}: {eq($:key, $selected_option)}<br />
		{/section}
	{/let}
{/let}

...returns the following output:

 all: 1
1:
2:
3:
4:
5:
6:
0: 1

As you might guess, I was expecting only the first iteration to evaluate to true.

Thanks in advance !

Sincerely,

Hi again!

I've closed the bug. The reason for the bug:

This is because of the way PHP works, and the way it converts strings to integers and visa versa. The resolution is to not to compare integers to strings (or to not to compare strings with the number 0).

A resolution to your problem is either to use 7 or -1 as sunday, or use a number for "any".

Kristian
