ACF前端的形式更新項

我想用ACF前端形式函數來創建帶定製字段的形式ACF前端的形式更新項

我看到這個問題了創建新名詞，@Alhana ACF front end form to create term 但我想生成表單與舊數據

嗯，我沒有看到這個問題，但如果它仍然是實際的，這是一個解決方案。首先，確保你有ACF組，鏈接到你的分類。您需要ID這組，它可以在URL組編輯頁面上找到，例如：

http://site.ru/wp-admin/post.php?post=340&action=edit

在這種情況下，組ID 。如果你不希望使用硬編碼ID（如果你的組不時改變），你可以得到它，使用組名（在這個例子中的組名是TECHNIC CPT）：

global $wpdb; 
$group_ID = $wpdb->get_var("SELECT ID FROM $wpdb->posts WHERE post_title = 'Technic CPT'");

然後，您需要您正在更新的術語ID。我認爲，這不是nesessary寫得到它，因爲它是WP基礎:)你會用這樣的結尾：

$term_id = 405;

最後，你需要你的分類的蛞蝓。在這個例子中，它是技術。所以，讓我們渲染我們的表單！

acf_form_head(); 
$acf_form_args = array(
    'id' => 'technic_edit_form', 
    'post_id' => 'technic_'.$term_id, 
    'form' => true, 
    'submit_value' => 'Update technic', 
    'field_groups' => array($group_ID), 
    'updated_message' => 'Technic is updated!'; 
); 
acf_form($acf_form_args);

現在您的術語的自定義字段將以此格式顯示。但爲了在編輯後保存術語數據，您需要添加更多代碼。 ACF表格假定您正在保存發佈數據，我們將添加一些邏輯來檢測爲術語保存數據。

add_filter('acf/pre_save_post', 'acf_handle_form_save', 10, 1); 
function acf_handle_form_save($post_id) { 
    // Function accepts id of object we're saving. 
    // All WordPress IDs are unique so we can use this to check which object it is now. 
    // We'll try to get term by id. 
    // We'll get term id with added taxonomy slug, for example 'technic_405'. 
    // For checking term existence we must cut out this slug. 
    $cut_post_id = str_replace('technic_', '', $post_id); 
    $test_tax_term = get_term_by('id', $cut_post_id, 'technic'); 
    // If $test_tax_term is true - we are saving taxonomy term. 
    // So let's change form behaviour to saving term instead of post. 
    if ($test_tax_term) : 
    // Get array of fields, attached to our taxonomy 
    global $wpdb; 
    $group_ID = $wpdb->get_var("SELECT ID FROM $wpdb->posts WHERE post_title = 'Technic CPT'"); 
    $acf_fields = acf_get_fields_by_id($group_ID); 
    // Then sanitize fields from $_POST 
    // All acf fields will be in $_POST['acf'] 
    foreach ($acf_fields as $acf_field) : 
     $$acf_field[ 'name' ] = trim(esc_attr(strip_tags($_POST[ 'acf' ][ $acf_field[ 'key' ] ]))); 
    endforeach; 
    // We need to have some fields in our group, which are just duplicates of standard term fields: name, slug, description. 
    // In this example it's only one field - term name, called 'technic_name'. 
    $name = 'technic_name'; 
    // Update base term info, in this example - only name. 
    $term = wp_update_term($cut_post_id, 'technic', array('name' => $$name)); 
    // If all is correct, update custom fields: 
    if (!is_wp_error($term)) : 
     foreach ($acf_fields as $acf_field) : 
     update_field($acf_field[ 'name' ], $$acf_field[ 'name' ], 'technic_' . $cut_post_id); 
     endforeach; 
    endif; 
    else : 
    // Here is saving usual post data. Do what you need for saving it or just skip this point 
    endif; 
    return $post_id; 
}

請注意：$ _ POST數據驗證可能會更復雜。例如，如果在分類法字段之間存在ACF圖庫或關係，則可能必須驗證值的數組。在我的例子中，我只有普通的文本字段。

希望有幫助！
