Posted: Thu Nov 20, 2003 9:30 am Post subject: How to get data from an array returned by an object

Let's say I've got this code:

Code:

class Thingy {
function test () {
$myArray['this']='something';
$myArray['that']='something else';
}
}

$thingy = new Thingy();
$smarty->register_object("thingy",$thingy);
....

So now in my template file I have:

Code:

{thingy->test assign="output"}

How do I get ['this'] and ['that'] out of $output? If I display {$output} in my template file I get "Array" so the object is there. If I loop through the array with a {section} tag, it'll loop twice. But no matter what I try I can't get it to print out the values.

I'll go ahead and list what I've tried:

{$output.this} = nothing prints
{$output['this']} = not valid syntax
{$output[this] = nothing prints
{$output[0]} = nothing prints

I know I'm getting my array back. How do I get the data?

you have to return $myArray from the method.

Oh, right, but I do. I just didn't type it into my example.

Code:

class Thingy {
function test () {
$myArray['this']='something';
$myArray['that']='something else';
return $myArray;
}
}

I do that. But when I do this:
{thingy->test assign="output"}

I can't figure out how to reference output['that'].

{$output.that} should do. {thingy->test\|@debug_print_var} should print the array.

I figured it out. I was doing this (this is my real code):

Code:

<?php
// $album->getFolderInfo($dir_id) returns an array
// with name, dir_id, parent_dir_id, and description
$thisDir = $album->getFolderInfo($dir_id);
?>

Then in my template:

Code:

{album->getFolderInfo p1="$thisDir.dir_id" assign="output"}
{$output.name}

I know that thisDir already had these things, but I was just testing out the template. I tried $output.name, $output[name], etc. I also tried p1="$thisDir.dir_id", p1="'$thisDir.dir_id'", p1='$thisDir.dir_id' etc. but none of these would actually pass in the value (they would either pass in Array.dir_id or fail).

Then I did this:

Code:

{album->getFolderInfo p1=$thisDir.dir_id assign="output"}{$output.name}

And it works fine. so my problem was the quotes. Sheesh. I spent a lot of time figuring that out.

I'm only posting all this for others who may find themselves in a simlar situation.

Thanks for the help.

Well, I'm sure glad you found it -- indeed, only use quotes where necessary, especially when passing arrays around. Otherwise, you get similiar results to those you'd get if you tried the same thing in PHP.

lol, it helps when the code snippets you post match your actual broken code example, huh Smile

Thanks for the follow-up!
