Php 在数组中搜索并在prestashop中使用smarty返回父节点

大家好

我正在编写一个模块，目前在.tpl中，我正在尝试检索当前显示页面的语言id。实际上，我正在编写一些测试代码，以了解是否有所有的元素可以继续

到目前为止，我有：

id={$smarty.get.id_category}
id_language = {$smarty.get.id_lang}
{assign var=my_lang_id value=$smarty.get.id_lang}
my_lang_id= {$my_lang_id}    
languages = {$languages|@print_r}

事实上，我得到了：

id=7
id_language = 6
my_lang_id= 6
languages = Array
(
    [0] => Array
        (
            [id_lang] => 1
            [name] => English (English)
            [active] => 1
            [iso_code] => en
            [language_code] => en-us
            [date_format_lite] => m/j/Y
            [date_format_full] => m/j/Y H:i:s
            [is_rtl] => 0
            [id_shop] => 1
            [shops] => Array
                (
                    [1] => 1
                )

        )

    [1] => Array
        (
            [id_lang] => 6
            [name] => Italiano (Italian)
            [active] => 1
            [iso_code] => it
            [language_code] => it
            [date_format_lite] => d/m/Y
            [date_format_full] => d/m/Y H:i:s
            [is_rtl] => 0
            [id_shop] => 1
            [shops] => Array
                (
                    [1] => 1
                )

        )

    [2] => Array
        (
            [id_lang] => 7
            [name] => English (United Kingdom)
            [active] => 1
            [iso_code] => gb
            [language_code] => gb
            [date_format_lite] => d/m/Y
            [date_format_full] => d/m/Y H:i:s
            [is_rtl] => 0
            [id_shop] => 1
            [shops] => Array
                (
                    [1] => 1
                )

        )

    [3] => Array
        (
            [id_lang] => 8
            [name] => English (Australia)
            [active] => 1
            [iso_code] => au
            [language_code] => en-au
            [date_format_lite] => d/m/Y
            [date_format_full] => d/m/Y H:i:s
            [is_rtl] => 0
            [id_shop] => 1
            [shops] => Array
                (
                    [1] => 1
                )

        )

    [4] => Array
        (
            [id_lang] => 9
            [name] => English (Canada)
            [active] => 1
            [iso_code] => ca
            [language_code] => en-ca
            [date_format_lite] => d/m/Y
            [date_format_full] => d/m/Y H:i:s
            [is_rtl] => 0
            [id_shop] => 1
            [shops] => Array
                (
                    [1] => 1
                )

        )

我的问题是。。。我想从这个数组中检索我当前语言的iso_代码，以及给定语言的iso_代码和语言_代码。。。假设我想用“it”，“it”，因为我当前的语言id是6，然后我想用iso_code=en获得语言的id_lang，这可能吗？或者我走错了方向？

以下是使用smarty进行比较的方法：

PHP测试文件：

$languages = array();
$languages[] = array('id_lang' => 1, 'iso_code' => 'en', 'language_code' => 'en-us');
$languages[] = array('id_lang' => 6, 'iso_code' => 'it', 'language_code' => 'it');
$languages[] = array('id_lang' => 7, 'iso_code' => 'gb', 'language_code' => 'gb');
$smarty->assign('languages',$languages);

{assign var=my_lang_id value=6}

{foreach $languages as $lang}
    {if $lang.id_lang eq $my_lang_id}
       {$lang.iso_code} {$lang.language_code}
    {/if}
{/foreach} 

Smarty测试文件：

$languages = array();
$languages[] = array('id_lang' => 1, 'iso_code' => 'en', 'language_code' => 'en-us');
$languages[] = array('id_lang' => 6, 'iso_code' => 'it', 'language_code' => 'it');
$languages[] = array('id_lang' => 7, 'iso_code' => 'gb', 'language_code' => 'gb');
$smarty->assign('languages',$languages);

{assign var=my_lang_id value=6}

{foreach $languages as $lang}
    {if $lang.id_lang eq $my_lang_id}
       {$lang.iso_code} {$lang.language_code}
    {/if}
{/foreach} 

我希望这就是你需要的，因为我根本不了解普雷斯塔什
