Access php array in smarty
I have a object with a method like this: $foo->getId() which returns an integer, and i开发者_开发百科 have an array like:
$array(
1=> array(
"parent_id" => 14
),
2=> array(
"parent_id" => 15
)
);
I need to access parent_id inside the subarray in smarty using the $foo->getId() as index key for $array, something like:
{$array[$foo->getId()].parent_id}
also tried just:
{$array[$foo->getId()]}
But both return error:
syntax error: unidentified token
What am i not doing right?
You can try:
{$array.$foo->getId().parent_id}
If this does not work, I think you have to assign the ID to an other variable beforehand:
{assign var=foo_id value=`$foo->getId()`}{$array.$foo_id.parent_id}
In Smarty 3, this should work:
{$array.{$foo->getId()}.parent_id}
I have just tried to get the same error as you. Funny thing is, the code runs fine. Here we go for the specs: Smarty 3.0.7 with PHP 5.3.4.
My template code:
<html>
<head>
<title>Smarty</title>
</head>
<body>
Hello, {$array[2]["parent_id"]}<br/>
Hello, {$array[$foo->getId()]["parent_id"]}<br/>
</body>
</html>
The php file:
<?php
class Foo {
public function getId() {
return 2;
}
}
// ... smarty config left out ... $smarty has been assigned successfully
$foo = new Foo();
$array = array(
1 => array("parent_id" => 14),
2 => array("parent_id" => 15)
);
$smarty->assign('array', $array);
$smarty->assign('foo', $foo);
$smarty->display('index.tpl');
?>
The Output:
Hello, 15
Hello, 15
Try this:
$array[$foo->getId()]["parent_id"]I will use a variable that way:
$a=array(
1 => array(
"parent_id" => 14
),
2 => array(
"parent_id" => 15
)
);
Then you can access your array like this:
$a[1]["parent_id"]
First, don't forget to pass the tow variables to Smarty
$smarty->assign('array', $array);
$smarty->assign('foo', $foo);
And, in your Smarty Template, use :
{$array[$foo->getId()]["parent_id"]}
Never used smarty, but in PHP you can do:
<?php
class foo {
public function getId() {
return (int)2;
}
}
$array = array(
1 => array(
"parent_id" => 14
),
2 => array(
"parent_id" => 15
)
);
$foo = new Foo;
echo $array[(int)$foo->getId()]['parent_id'];
//15
I've type casted as integer (int)$foo->getID() because the $array indexes are integers, enclosing them in brackets {} type castes them in strings.
(Maybe you should look at Foo::getID() and see if returns a string)
In smarty then, you could do something like this (theoretically, since I can't test it in smarty):
{$array[(int)$foo->getId()]['parent_id']}
//Also check if this works, but I suspect it shouldn't (the syntax it's not valid PHP)
{$array.(int)$foo->getId().parent_id}
Try This. From the php file assign object to smarty variable 'foo'
{assign var="val" value=$foo->getId()}
{$arr.$val.parent_id}
