I have an array like above but I don't know how to loop it with foreach or section in smarty. Is anyone can give me a hand for this? I spend a daytime for it so please give me some idea. Thank you anyway!!

Answer 1

You could do nested foreach statements

foreach($array as $childArray)
{
    foreach($childArray as $obj)
    {
        echo $obj->0;
    }
}

Although I'm not sure variables are properly named if they have a number at the first character, so you might need to access it using brackets

$obj->{0};

Answer 2

{foreach from=$menu key=k item=v name=menu}
    {if $smarty.foreach.menu.index == 0}
        VietMusic
    {/if}
    {if $smarty.foreach.menu.index == 1}
        ForeignMusic
    {/if}
    {if $smarty.foreach.menu.index == 2}
        SpecialMusic
    {/if}
        {foreach from=$v item=submenu}
             {$submenu}
        {/foreach}
    {/foreach}

I'm write out my array like that but It's not optimize, Is anyone give another idea for this?

Finally I can do it like that,

{foreach from=$menu key=k item=v name=menu}
    {foreach from=$v item=submenu name=sub}
        {if $smarty.foreach.sub.first}
            {$submenu}
        {else}
            {$submenu}
        {/if}
    {/foreach}
{/foreach}
