Hi,

i have two array, each containing several records of two different tables of my database.
One contains the existing calendars, the other one the entries. One field of the entry table contains the id of the calendar the entry belongs to.
The index of each array are the ids of the records.

Looks like this:
$calendars = array(
'10' => array(
'id' => 10,
'name' => "sample calendar"
),
'15' => array(
'id' => 15,
'name' => "another sample calendar"
)
)

$entries = array(
'500' => array(
'id' => 500,
'title' => "sample entry",
'calendarid' => 15
)
)


Now i want to list all entries and the name of the calendar it belongs to.

Code:

ID, Title, Calendar-Name<br>
{foreach from=$entries item=entry}
{$entry.id}, {$entry.title}, {$calendars[$entry.calendarid].name}<br>{/foreach}

Output:

ID, Title, Calendar-Name
500, sample entry,

But why?

If i use the following code it works:

ID, Title, Calendar-Name
{foreach from=$entries item=entry}
{assign var=calendarid value=$entry.calendarid}
{$entry.id}, {$entry.title}, {$calendars[$calendarid].name}<br>{/foreach}


Why is the first way wrong?

Thx in Advance,

easy:

$entry.calendarid = 10 (and 15)

BUT:

$calendars[10] = null

while

$calendars["10"] = array(
'id' => 10,
'name' => "sample calendar"
)

You are confusing (string) associative keys with (integer) indexes. In the second case, you obviate that by not accessing by your stored index values but instead, by the key value found in the array itself (ie: "10").
