Is it possible to iterate over a multi-dimensional array in smarty?
Can someone provide a simple demo? I can't 开发者_开发百科seem to get my head around the smarty syntax for iterating over an array that looks like the one below. I want to get at values at all levels.
Array
(
[0] => Array
(
[id] => 0
[name] => 12312
[sub24] => Array
(
[0] => Array
(
[classid] => 157
[classname] => 24011010
)
[1] => Array
(
[classid] => 170
[classname] => 24011020
)
[2] => Array
(
[classid] => 183
[classname] => 24011030
)
)
[sub23] => Array
(
[0] => Array
(
[classid] => 60
[classname] => 23011010
)
[1] => Array
(
[classid] => 73
[classname] => 23011030
)
[2] => Array
(
[classid] => 85
[classname] => 23012030
)
)
[sub22] => Array
(
[0] => Array
(
[classid] => 1
[classname] => 22011010
)
[1] => Array
(
[classid] => 13
[classname] => 22012010
)
[2] => Array
(
[classid] => 24
[classname] => 22012020
)
)
)
Not tested, but from the top of my head, something like this.
Note: I'm doing it like this because you said you wanted Smarty Syntax. Normally I'd stuff this into a helper function, create the list/table/whatever there, and just call the helper function from within Smarty.
<html>
<head><title>Smarty Foreach Demo</title></head>
<body>
<p>This code assumes you have $smarty->assign()'ed $var to be your multi-dimensional array</p>
<ul>
{foreach from=$var key=key1 item=lvl1}
<li>Current key: $key1,
Current value:
{if !is_array($lvl1)}
{$lvl1}
{else}
Array:<ul>
{foreach from=$lvl1 key=key2 item=lvl2}
<li>Current key: $key1,
Current value:
{if !is_array($lvl1)}
{$lvl1}
{else}
Even deeper array.. keep doing same stuff!
{/if}
</li>
{/foreach}
</ul>
{/if}
{/foreach}
</ul>
</body>
You can do it like how you iterate over a PHP array:
See here for example.
foreach ($array as $i => $value) {
PrintValue($i, $value);
}
function PrintValue($key, $val)
{
echo $key;
if(is_array($val))
{
foreach($val as $i=>$value)
{
PrintValue($i, $value);
}
}
else
{
echo $val;
}
}
Or, you can use $print_r($arr), this would print everything inside an array, including the array inside array element.
see smarty doc here (example 7.33)
{foreach from=$multi_array item=i}
{if is_array($i) && count($i) > 0}
{foreach from=$i item=j} <!-- if it is an array, lets create a loop from item=i, note the "$" in from=$i -->
Class id: {$j.classid}<br />
Class name: {$j.classname}<br />
{/foreach}
{else}
{$i} <!-- will print id/name of your array -->
{/if}
{/foreach}
