我在Wordpress的前端有一个表单，它保存了除复选框数组之外的所有字段。如果我在后端帖子编辑器中勾选框，并且勾号正确显示在前面，它将显示并保存正确的值。然而，在前端勾选方框并不能保存！所有其他字段从字体和背面正确保存。我花了很长时间试图弄明白这一点，但它似乎不起作用，任何帮助都是greatly 非常感谢。代码如下：

$query = new WP_Query( array( \'post_type\' => \'property\', \'posts_per_page\' => \'-1\' ) ); 

if ( $query->have_posts() ) : while ( $query->have_posts() ) : $query->the_post(); 

if(isset( $_GET[\'post\'] ) ) {
    if ( $_GET[\'post\'] == $post->ID ) {
        $current_post = $post->ID;
        $options = $custom_meta_fields[7][\'options\'];
        $checkboxes = get_post_meta($current_post, \'custom_cgtest\', true);
}
}
endwhile; endif; 
wp_reset_query();
global $current_post;

if(isset($_POST[\'submitted\']) && isset($_POST[\'post_nonce_field\']) && wp_verify_nonce($_POST[\'post_nonce_field\'], \'post_nonce\')) {
$post_information = array(
\'ID\' => $current_post,
\'post_title\' => ($_POST[\'post_title\']),
\'post_content\' => esc_attr(strip_tags($_POST[\'postContent\'])),
\'post-type\' => \'property\',
\'post_status\' => \'publish\',
);    

$post_id = wp_update_post($post_information);
if($post_id) { 
update_post_meta($post_id, \'custom_cgtest\', ($_POST[\'cbn\']));
}
}

在页面中：

foreach ($options as $option) {  
    echo \'<input type="checkbox" name="cbn[]" id="\'.$option[\'value\'].\'"\',$checkboxes && in_array($option[\'value\'], $checkboxes) ? \' checked="checked"\' : \'\',\' /> \';
    echo $option[\'value\'];
    }

在函数中。php：

array (  
\'label\' => \'Checkbox Group\',  
\'desc\'  => \'A description for the field.\',  
\'id\'    => $prefix.\'cgtest\',  
\'type\'  => \'cgtest\',  
\'options\' => array (  
    \'one\' => array (  
        \'label\' => \'Option One\',  
        \'value\' => \'one\'  
    ),  
    \'two\' => array (  
        \'label\' => \'Option Two\',  
        \'value\' => \'two\'  
    ),  
    \'three\' => array (  
        \'label\' => \'Option Three\',  
        \'value\' => \'three\'  
    )  
)  
)

如果你需要更多的代码，请告诉我。

echo \'<input type="checkbox" name="cbn[]" id="\'.$option[\'value\'].\'"\',$checkboxes && in_array($option[\'value\'], $checkboxes) ? \' checked="checked"\' : \'\',\' /> \';

echo \'<input type="checkbox" name="cbn[]" id="\'.$option[\'value\'].\'"\'.$checkboxes && in_array($option[\'value\'], $checkboxes) ? \' checked="checked"\' : \'\'.\' /> \';

echo \'<input type="checkbox" name="cbn[]" id="\' . $option[\'value\'] .    \'"\' . ( $checkboxes && in_array( $option[\'value\'], (array) $checkboxes ) ? \' checked="checked"\' : \'\' ) . \' /> \';
