How to print a json in Smarty

Question

Am getting a json from an api, how to print the json using Smarty.

Json format

[
    {
        "first_name": "jinu",
        "last_name": "mk",
        "loginid": "[email protected]",
        "timezone": "5.5",
        "team_id": "c964ef415f157ddd99173f5b481ee1e3",
        "user_type": 1,
        "last_login_date": null
    },
    {
        "first_name": "avatar second",
        "last_name": "test",
        "loginid": "[email protected]",
        "timezone": "5.5",
        "team_id": "ec40f5feda8643135bc20be44f897b03",
        "user_type": "3",
        "last_login_date": null
    },
    {
        "first_name": "avatar testing admin",
        "last_name": "amt 1",
        "loginid": "[email protected]",
        "timezone": "5.5",
        "team_id": "ec40f5feda8643135bc20be44f897b03",
        "user_type": 1,
        "last_login_date": null
    }
]

I have tired the following foreach but its not printing anything.

{foreach from=$games item=foo}
     <li>{$foo.first_name}</li>
{/foreach}

Please help me to solve this issue. Thanks

Answer 1

You have 2 possible solutions.

First solution

in PHP you use:

$data = '[
    {
        "first_name": "jinu",
        "last_name": "mk",
        "loginid": "[email protected]",
        "timezone": "5.5",
        "team_id": "c964ef415f157ddd99173f5b481ee1e3",
        "user_type": 1,
        "last_login_date": null
    },
    {
        "first_name": "avatar second",
        "last_name": "test",
        "loginid": "[email protected]",
        "timezone": "5.5",
        "team_id": "ec40f5feda8643135bc20be44f897b03",
        "user_type": "3",
        "last_login_date": null
    },
    {
        "first_name": "avatar testing admin",
        "last_name": "amt 1",
        "loginid": "[email protected]",
        "timezone": "5.5",
        "team_id": "ec40f5feda8643135bc20be44f897b03",
        "user_type": 1,
        "last_login_date": null
    }
]';


$smarty->assign('games',$data);

In Smarty you use:

{foreach from=$games|json_decode item=foo}
     <li>{$foo->first_name}</li>
{/foreach}

However I'm not sure in this case if json_decode is run on $games just once or on each invocation.

Second solution

In PHP you use:

$data = '[
    {
        "first_name": "jinu",
        "last_name": "mk",
        "loginid": "[email protected]",
        "timezone": "5.5",
        "team_id": "c964ef415f157ddd99173f5b481ee1e3",
        "user_type": 1,
        "last_login_date": null
    },
    {
        "first_name": "avatar second",
        "last_name": "test",
        "loginid": "[email protected]",
        "timezone": "5.5",
        "team_id": "ec40f5feda8643135bc20be44f897b03",
        "user_type": "3",
        "last_login_date": null
    },
    {
        "first_name": "avatar testing admin",
        "last_name": "amt 1",
        "loginid": "[email protected]",
        "timezone": "5.5",
        "team_id": "ec40f5feda8643135bc20be44f897b03",
        "user_type": 1,
        "last_login_date": null
    }
]';



$smarty->assign('games',json_decode($data));

In Smarty file:

{foreach from=$games item=foo}
     <li>{$foo->first_name}</li>
{/foreach}

I always recommend using second method, because if possible in Smarty you should avoid using any calculations and just display data.

Answer 2

Try the following:

{foreach from=$games item=foo}
     {assign var=bar value=$foo|json_decode:1}
     <li>{$bar.first_name}</li>
{/foreach}
