我正在尝试在Wordpress中实现以下目标:
我的类别中有一个额外的所见即所得字段,设置为术语元。我将其显示在我的category.php模板文件中。 但是,如果该字段为空,则该类别应检查其直接父级,如果发现那里的字段不为空,则应继承该字段。如果直接父母将其清空,请转到更高级别,检查并显示是否找到。我需要深入5个级别,而不是更多。如果整个继承树中的所有字段均为空,则当然不显示任何内容。
到目前为止,这是我的代码,所以您有个好主意。
$category = get_the_category();
$ancestors = get_ancestors( $category[0]->term_id, 'category' );
$direct_parent_id = $ancestors[0];
$topmost_parent_id = $ancestors[1];
$level = asb_get_cat_level( $cat );
if(function_exists('get_tax_meta')) {
/* First get Section partner fields */
$cat_part = get_term_meta(get_queried_object_id(),'cat_part_wysiwyg', true);
$cat_part_parent = get_term_meta($direct_parent_id,'cat_part_wysiwyg', true);
$cat_part_grandparent = get_term_meta($topmost_parent_id,'cat_part_wysiwyg', true);
/* Construct output for Section partners */
$cat_partner = '<div class="category-partners">' . $cat_part . '</div>';
$cat_partner_parent = '<div class="category-partners"> ' . $cat_part_parent . '</div>';
$cat_partner_grandparent = '<div class="category-partners">' . $cat_part_grandparent . '</div>';
/* Start showing Section partners */
if( !empty($cat_part_grandparent) ) {
print_r($cat_partner_grandparent);
} elseif( !empty($cat_part_parent) ) {
print_r($cat_partner_parent);
} elseif ( !empty($cat_part) ) {
print_r($cat_partner);
} else {
/* Die */
}
}
加上我的functions.php具有以下代码:
function asb_get_cat_level($id, $type = 'category') {
return count( get_ancestors($id, $type) );
}
(我在($ level == 1)等条件条件内使用此函数)
到目前为止,只有最高级的类别显示为“部门”伙伴,但子级没有继承它们。
答案 0 :(得分:0)
我最终使用了这段代码
// Section Partners
function section_partners() {
$cat_id = get_query_var('cat');
$ancestors = get_ancestors( $cat_id, 'category' );
$parent_one = $ancestors[0];
$parent_null = $ancestors[1];
$parent_two = $ancestors[2];
// $level = asb_get_cat_level( $cat );
if(function_exists('get_tax_meta')) {
/* First get Section partner fields */
$cat_part = get_term_meta(get_queried_object_id(),'cat_part_wysiwyg', true);
$cat_part_parent = get_term_meta($parent_one, 'cat_part_wysiwyg', true);
$cat_part_grandparent = get_term_meta($parent_null,'cat_part_wysiwyg', true);
$cat_part_grandgrandparent = get_term_meta($parent_two,'cat_part_wysiwyg', true);
/* Construct output for Section partners */
$cat_partner = '<div class="category-partners"><div>' . $cat_part . '</div></div>';
$cat_partner_parent = '<div class="category-partners"><div>' . $cat_part_parent . '</div></div>';
$cat_partner_grandparent = '<div class="category-partners"><div>' . $cat_part_grandparent . '</div></div>';
$cat_partner_grandgrandparent = '<div class="category-partners"><div>' . $cat_part_grandgrandparent . '</div></div>';
if ( !empty($cat_part) ) { /* if top category has partners */
print_r($cat_partner);
} elseif ( !empty($cat_part_parent) ) { /* if 1 level category has partners */
print_r($cat_partner_parent);
} elseif ( !empty($cat_part_grandparent) ) { /* if 2 level category has partners */
print_r($cat_partner_grandparent);
} elseif ( !empty($cat_part_grandgrandparent) ) { /* if 3 level category has partners */
print_r($cat_partner_grandgrandparent);
} elseif ( empty($cat_part_parent) && !empty($cat_part) ) { /* inherit from top level */
print_r($cat_partner);
} elseif ( empty($cat_part_parent) && empty($cat_part_grandparent) && !empty($cat_part) ) { /* inherit from 1 level */
print_r($cat_partner);
} elseif ( empty($cat_part_grandparent) && empty($cat_part_grandgrandparent) && !empty($cat_part_parent) ) { /* inherit from 2 level */
print_r($cat_partner_parent);
} elseif ( empty($cat_part_parent) && empty($cat_part_grandparent) && empty($cat_part_grandgrandparent) && !empty($cat_part) ) { /* inherit from 2 level */
print_r($cat_partner);
} else {
/* Die */
}
}
}
但是仍然需要修复PHP错误$ parent_one,$ parent_null和$ parent_two返回空。
