Question

This line:

{$data["bank_data"]["Arrangement"]["id"]}

returns the following error:

PHP (5.3.9) ERROR (E_USER_ERROR):
File: Smarty.class.php
Line: 1092
Type: Smarty error: [in tke-g-admin_scopeofwork.tpl line 10]: syntax error: unrecognized tag: $data[“bank_data”][“Arrangement”][“id”] (Smarty_Compiler.class.php, line 446)

This line:

{$data.bank_data.Arrangement.id}

does not return error. It works correctly.

So, why the first section is wrong? How to use [] to access array.

Answer 1

Judging from the error you posted, you’re using Smarty2. The Docs give you two options for accessing arrays:

{* for string indexes *}
{$some.array.value}
{* for numeric indexes *}
{$some[0][1]}

you can use a variable to provide an index like so

{assign var="key" value="array"}
{$some.$key.value} == {$some.array.value}

using that “trick”, you can also access string indexes containing “special characters” such as ., [] or .

Smarty3 is a bit more flexible in that way:

{$some.{"hello world"}.array["array"]['foo']}

oddly enough {$foo[bar]} is not parsed properly (in Smarty 3.1.10). Threw that on the todo list, though.
