更改多维数组中的值

Question

我正在尝试更改多维数组中的数组的值，给定条件。

$arg_pub = array(
    'post_type' => 'pubs',
    'order' => 'ASC',
    'orderby' => 'meta_value_num',
    'meta_key' => 'pub_y',
    'meta_query' => array(
        array(
            'key' => 'pub_y',
            'value' => array( $_period_from, $_period_to),
            'type' => 'numeric',
            'compare' => 'BETWEEN'
        ),
    ),      
    'tax_query' => array(
        array(
            'taxonomy' => 'index',
            'field'    => 'slug',
            'terms'    => array('one', 'two', 'three'),
        ),
        array(
            'taxonomy' => 'class',
            'field'    => 'slug',
            'terms'    => array('aaa', 'bbb', 'ccc'),
        ),
        array(
            'taxonomy' => 'author',
            'field'    => 'slug',
            'terms'    => array('joe', 'peter', 'mark'), //array to be changed
        ),
    ),
);
if ( $some_condition ) {
    // I want to only replace the values from this specific array from the $arg_pub:
    // terms => array('joe', 'peter', 'mark')
    $arg_pub['tax_query'][...]['terms'] = array('susan', 'martha');
    // EDIT: with [...] I mean that I don't know what to write there.
    // The position for this array won't be always [2], it could change.
}

是否有必要做一个 foreach 循环？任何帮助将不胜感激！

Answer 1

不确定省略号在做什么，但你试过吗：

$arg_pub['tax_query'][2]['terms'] = array('susan', 'martha');

===

更新：

这对你有用吗？

...
'tax_query' => array(
    'index' => array(
        'taxonomy' => 'index',
        'field'    => 'slug',
        'terms'    => array('one', 'two', 'three'),
    ),
    'class' => array(
        'taxonomy' => 'class',
        'field'    => 'slug',
        'terms'    => array('aaa', 'bbb', 'ccc'),
    ),
    'author' => array(
        'taxonomy' => 'author',
        'field'    => 'slug',
        'terms'    => array('joe', 'peter', 'mark'), //array to be changed
    ),
),
...
$arg_pub['tax_query']['author']['terms'] = array('susan', 'martha');

更新 2：

试试这个：

foreach($arg_pub['tax_query'] as &$taxq){
    if($taxq['taxonomy'] == 'author'){
        $taxq['terms'] = array('susan', 'martha');
    }
}

Answer 2

只需将...替换为 2 ：

$arg_pub = array(
    'post_type' => 'pubs',
    'order' => 'ASC',
    'orderby' => 'meta_value_num',
    'meta_key' => 'pub_y',
    'meta_query' => array(
        array(
            'key' => 'pub_y',
            'value' => array( $_period_from, $_period_to),
            'type' => 'numeric',
            'compare' => 'BETWEEN'
        ),
    ),      
    'tax_query' => array(
        array(
            'taxonomy' => 'index',
            'field'    => 'slug',
            'terms'    => array('one', 'two', 'three'),
        ),
        array(
            'taxonomy' => 'class',
            'field'    => 'slug',
            'terms'    => array('aaa', 'bbb', 'ccc'),
        ),
        array(
            'taxonomy' => 'author',
            'field'    => 'slug',
            'terms'    => array('joe', 'peter', 'mark'), //array to be changed
        ),
    ),
);
if ( $some_condition ) {
    // I want to only replace the values from this specific array from the $arg_pub:
    // terms => array('joe', 'peter', 'mark')
    $arg_pub['tax_query'][...]['terms'] = array('susan', 'martha');
}
