我正在尝试找到一种方法(使用 wordpress 插件 ACF)来输出整个字段组。
我有两个“字段组”，如果其中一个是“事件的”(带有一个复选框)，我想将它们回显到我的模板中。
问题是，如何从一个“字段组”中获取所有字段数据的数组？
现在我正在尝试以下操作:
<?php
$group_ID = 37;
$fields = array();
$fields = apply_filters('acf/field_group/get_fields', $fields, $group_ID);
echo "<pre>";
print_r($fields);
echo "</pre>";
?>
它输出一个字段数组，但据我所知它不包含实际数据:
Array
(
[0] => Array
(
[key] => field_537b79d92081f
[label] => Active-1
[name] => active-1
[_name] => active-1
[type] => true_false
[order_no] => 0
[instructions] =>
[required] => 0
[id] => acf-field-active-1
[class] => true_false
[conditional_logic] => Array
(
[status] => 0
[rules] => Array
(
[0] => Array
(
[field] => null
[operator] => ==
)
)
[allorany] => all
)
[message] =>
[default_value] => 0
[field_group] => 37
)
[1] => Array
(
[key] => field_537b78a4c743e
[label] => Title-1
[name] => title-1
[_name] => title-1
[type] => text
[order_no] => 1
[instructions] =>
[required] => 0
[id] => acf-field-title-1
[class] => text
[conditional_logic] => Array
(
[status] => 0
[rules] => Array
(
[0] => Array
(
[field] => field_537b79d92081f
[operator] => ==
[value] => 1
)
)
[allorany] => all
)
[default_value] =>
[placeholder] =>
[prepend] =>
[append] =>
[formatting] => html
[maxlength] =>
[field_group] => 37
)
[2] => Array
(
[key] => field_537b78c6c743f
[label] => Info-1
[name] => info-1
[_name] => info-1
[type] => textarea
[order_no] => 2
[instructions] =>
[required] => 0
[id] => acf-field-info-1
[class] => textarea
[conditional_logic] => Array
(
[status] => 0
[rules] => Array
(
[0] => Array
(
[field] => field_537b79d92081f
[operator] => ==
[value] => 1
)
)
[allorany] => all
)
[default_value] =>
[placeholder] =>
[maxlength] =>
[rows] =>
[formatting] => br
[field_group] => 37
)
)
我想基本上执行以下操作(请原谅 sudo/损坏的代码，PHP 不是我的语言):
<?php
$group_ID1 = 37;
$fields = array($group_ID1);
if ($fields1['active'] !== null) {
echo "<h1>";
echo $fields1['active']['text'];
echo $fields1['title']['text'];
echo $fields1['content']['text'];
echo "<h1>";
}
$group_ID2 = 38;
$fields2 = array($group_ID2);
if ($fields2['active'] !== null) {
echo "<h1>";
echo $fields2['active']['text'];
echo $fields2['title']['text'];
echo $fields2['content']['text'];
echo "<h1>";
}
?>
我还可以获得如下特定字段数据:
<?php
$field_key = "field_537b78c6c743f";
$field = get_field_object($field_key);
if($field) {
echo "<pre>";
print_r($field);
echo "</pre>";
}
?>
输出如下:
Array
(
[key] => field_537b78c6c743f
[label] => Info-1
[name] => info-1
[_name] => info-1
[type] => textarea
[order_no] => 2
[instructions] =>
[required] => 0
[id] => acf-field-info-1
[class] => textarea
[conditional_logic] => Array
(
[status] => 0
[rules] => Array
(
[0] => Array
(
[field] => field_537b79d92081f
[operator] => ==
[value] => 1
)
)
[allorany] => all
)
[default_value] =>
[placeholder] =>
[maxlength] =>
[rows] =>
[formatting] => br
[field_group] => 37
[value] => testtesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttesttest
)
但我真的需要为每个“字段组”调用每个字段键吗？一个“字段组”中不是所有字段的数组吗？
最佳答案
您可以获得属于一个组的所有字段的数组。函数是:
$acf_fields = acf_get_fields_by_id( $group_ID );
我们需要知道 ACF 字段组 ID。您可以在组编辑页面的 url 中找到它，例如:
http://site.ru/wp-admin/post.php?post=340&action=edit
在这种情况下，组 ID 是 340。如果您不想使用硬编码 ID(如果您的组不时更改)，您可以使用组名(在此示例中组名 id Technic CPT)获取它):
global $wpdb;
$group_ID = $wpdb->get_var( "SELECT ID FROM $wpdb->posts WHERE post_title = 'Technic CPT'" );
输出看起来像这样:
array(1) {
[0] => array(29) {
["ID"] => int(366)
["key"] => string(19) "field_55f05295a59ca"
["label"] => string(29) "Gallery of technic"
["name"] => string(15) "technic_gallery"
["prefix"] => string(0) ""
["type"] => string(7) "gallery"
["value"] => NULL
["menu_order"] => int(6)
["instructions"] => string(155) "Field instructions"
["required"] => int(0)
["id"] => string(0) ""
["class"] => string(0) ""
["conditional_logic"] => int(0)
["parent"] => int(340)
["wrapper"] => array(3) {
["width"] => int(50)
["class"] => string(0) ""
["id"] => string(0) ""
}
["_name"] => string(15) "technic_gallery"
["_input"] => string(0) ""
["_valid"] => int(1)
["min"] => string(0) ""
["max"] => int(10)
["preview_size"] => string(9) "thumbnail"
["library"] => string(3) "all"
["min_width"] => int(475)
["min_height"] => int(365)
["min_size"] => string(0) ""
["max_width"] => string(0) ""
["max_height"] => string(0) ""
["max_size"] => int(2)
["mime_types"] => string(0) ""
}
}
