仅在后端的某些页面上显示ACF字段

时间：2012-05-18 作者：Chris

我用高级自定义字段创建了一些自定义字段，并将它们设置为显示在名为X的自定义帖子类型中（帖子类型等于X）。

但我只需要将它们显示在这个自定义帖子类型的特定页面上，而不是所有页面上。

我该怎么做？

您不能通过ACF设置页执行此操作吗？您可以选择Post并将其设置为与标题相等。

事实证明，在显示标题下拉列表时，ACF不会查询自定义类型。要包含所有帖子类型，请在/core/admin/meta\\u box\\u位置。php，更改

<div rel="post">
    <?php 

    $choices = array();
    foreach(get_posts(array(\'numberposts\'=>\'-1\')) as $v)
    {
        $choices[$v->ID] = $v->post_title;
    }

    $this->create_field(array(
        \'type\'  =>  \'select\',
        \'name\'  =>  \'location[rules][\'.$k.\'][value]\',
        \'value\' =>  $rule[\'value\'],
        \'choices\' => $choices,
    ));

    ?>
</div>

至

<div rel="post">
    <?php 

    $choices = array();
    foreach(get_posts(array(\'numberposts\'=>\'-1\', \'post_type\'=>\'any\')) as $v)
    {
        $choices[$v->ID] = $v->post_title;
    }

    $this->create_field(array(
        \'type\'  =>  \'select\',
        \'name\'  =>  \'location[rules][\'.$k.\'][value]\',
        \'value\' =>  $rule[\'value\'],
        \'choices\' => $choices,
    ));

    ?>
</div>

如果您指的是删除您在帖子中通过PHP添加的某些字段。php或post new。php，当post类型满足特定条件时，可以使用acf\\u remove\\u local\\u field（$key）函数-请参阅https://www.advancedcustomfields.com/resources/register-fields-via-php/

我遵循以下思路：

<?php
// Add Local Field Groups and Local Fields
add_action(\'init\', array($this, \'function_to_add_fields_to_all_post_types\'), 999);

// Notice how the priority is higher on this set of add_action functions so it runs after the initial setup of the fields

// Remove Fields From Edit Post Screen
if ( $pagenow == \'post.php\' && get_post_type($_GET[\'post\']) != \'cpt\' ) {
    add_action(\'init\', array($this, \'remove_fields_from_cpt\'), 9999);
}

// Remove Fields From New Post Screen
if ( $pagenow == \'post-new.php\' ) {
    if(!isset($_GET[\'post_type\']) || $_GET[\'post_type\'] != \'cpt\'){
        add_action(\'init\', array($this, \'remove_fields_from_cpt\'), 9999);
    }
}

function function_to_add_fields_to_all_post_types(){
    // Add Local Fields using acf_add_local_field_group() or acf_add_local_field()
}

function remove_fields_from_cpt(){
    // Note: The \'key\' for your field is not the same as it\'s \'name\'
    acf_remove_local_field( \'key\');
}

我发现，仅在特定的管理屏幕上添加特定的字段就破坏了一些Ajax查找功能，因此添加到全部，然后从特定的管理屏幕中删除。

也许有一种更有效的方法可以做到这一点，但这对我来说很有效。

以下是一种更有效的方法：

这将检查编辑和添加屏幕，并使用“acf\\u remove\\u local\\u field（$key）”功能按键删除所选字段。

add_action(\'init\', \'remove_fields_from_cpt\', 9999);
function remove_fields_from_cpt(){
    global $pagenow;
    // Remove ACF fields from add/edit post
    if ( in_array( $pagenow, array( \'post.php\', \'post-new.php\' ), true )  
    && isset($_GET[\'post\']) || isset($_GET[\'post_type\']) 
    && in_array(\'YOUR_POST_TYPE\', array(get_post_type( $_GET[\'post\']), 
    get_post_type( $_GET[\'post_type\']) )) ) {
        $key = \'FIELD_KEY\';
        acf_remove_local_field($key);
    }   
}

结束

<div rel="post"> <?php $choices = array(); foreach(get_posts(array(\'numberposts\'=>\'-1\')) as $v) { $choices[$v->ID] = $v->post_title; } $this->create_field(array( \'type\' => \'select\', \'name\' => \'location[rules][\'.$k.\'][value]\', \'value\' => $rule[\'value\'], \'choices\' => $choices, )); ?> </div>

<div rel="post"> <?php $choices = array(); foreach(get_posts(array(\'numberposts\'=>\'-1\', \'post_type\'=>\'any\')) as $v) { $choices[$v->ID] = $v->post_title; } $this->create_field(array( \'type\' => \'select\', \'name\' => \'location[rules][\'.$k.\'][value]\', \'value\' => $rule[\'value\'], \'choices\' => $choices, )); ?> </div>

<?php // Add Local Field Groups and Local Fields add_action(\'init\', array($this, \'function_to_add_fields_to_all_post_types\'), 999); // Notice how the priority is higher on this set of add_action functions so it runs after the initial setup of the fields // Remove Fields From Edit Post Screen if ( $pagenow == \'post.php\' && get_post_type($_GET[\'post\']) != \'cpt\' ) { add_action(\'init\', array($this, \'remove_fields_from_cpt\'), 9999); } // Remove Fields From New Post Screen if ( $pagenow == \'post-new.php\' ) { if(!isset($_GET[\'post_type\']) || $_GET[\'post_type\'] != \'cpt\'){ add_action(\'init\', array($this, \'remove_fields_from_cpt\'), 9999); } } function function_to_add_fields_to_all_post_types(){ // Add Local Fields using acf_add_local_field_group() or acf_add_local_field() } function remove_fields_from_cpt(){ // Note: The \'key\' for your field is not the same as it\'s \'name\' acf_remove_local_field( \'key\'); }

add_action(\'init\', \'remove_fields_from_cpt\', 9999); function remove_fields_from_cpt(){ global $pagenow; // Remove ACF fields from add/edit post if ( in_array( $pagenow, array( \'post.php\', \'post-new.php\' ), true ) && isset($_GET[\'post\']) || isset($_GET[\'post_type\']) && in_array(\'YOUR_POST_TYPE\', array(get_post_type( $_GET[\'post\']), get_post_type( $_GET[\'post_type\']) )) ) { $key = \'FIELD_KEY\'; acf_remove_local_field($key); } }

一切都好吗<我需要wp-list-table 也要显示custom-fields 在每个custom-post 我有，但我不知道如何做到这一点，在这幅图中，它显示了带有字段的表格：Title, Author and Publication Date: 我想要的是能够选择custom-fields 将出现，例如以下示例Title, Carta, Naipe, Author, and Date of Publication:
