插件設置值不能保存wordpress

Question

我正在處理插件設置。首先，我保存在正常的方式插件設置和它完美的作品

這裏是我的舊代碼：

的index.php

add_action('admin_init', '_register_settings'); 
function _register_settings() { 
    register_setting('_settings_group', '_plugin_slug'); 
    register_setting('_settings_group', '_article_qty'); 
    register_setting('_settings_group', '_search_setting'); 
    register_setting('_settings_group', '_breadcrumbs_setting'); 
    register_setting('_settings_group', '_sidebar_home'); 
    register_setting('_settings_group', '_sidebar_inner'); 
    register_setting('_settings_group', '_comments_setting'); 
    register_setting('_settings_group', '_bgcolor'); 
} 

和settings.php配置

<?php 
    if(isset($_GET['settings-updated'])){ 
     echo 'Settings updated successfully'; 
    } 
?> 
<form method="post" action="options.php"> 
<?php 
    settings_fields('_settings_group'); 
?> 
<input type="text" name="_plugin_slug" id="_plugin_slug" value="<?php echo get_option('_plugin_slug'); ?>"> 

// Same other input fields 

<input type="submit" value="<?php _e('Save Changes','foo'); ?>" name="submit" id="submit"> 

它完美地保存了我的值，但是現在我更改了代碼以註冊設置並調用其值，但不工作，每次我保存值時，它都會在我提交表單後顯示空白頁。

這是我的新代碼：

的index.php

add_action('admin_init', '_register_settings'); 
function _register_settings() { 
    register_setting('_settings', '_settings', '_validate_settings'); 
} 

function kbe_validate_settings($input) { 
    $_clean = array(); 

    $_clean['_plugin_slug'] = isset($input['_plugin_slug']) ? sanitize_title($input['_plugin_slug']) : ''; 
    $_clean['_article_qty'] = intval($input['_article_qty']); 

    $_clean['_search_setting'] = isset($input['_search_setting']) && $input['_search_setting'] ? 1 : 0 ; 
    $_clean['kbe_breadcrumbs_setting'] = isset($input['_breadcrumbs_setting']) && $input['_breadcrumbs_setting'] ? 1 : 0 ; 

    $sidebar_positions = array(0, 1, 2); 

    $_clean['_sidebar_home'] = isset($input['_sidebar_home']) && in_array($input['_sidebar_home'], $sidebar_positions) ? intval($input['_sidebar_home']) : 0; 
    $_clean['_sidebar_inner'] = isset($input['_sidebar_inner']) && in_array($input['_sidebar_inner'], $sidebar_positions) ? intval($input['_sidebar_inner']) : 0; 

    $_clean['_comments_setting'] = isset($input['_comments_setting']) && $input['_comments_setting'] ? 1 : 0 ; 

    $_clean['_bgcolor'] = isset($input['_bgcolor']) ? sanitize_hex_color($input['_bgcolor']) : ''; 

    return $_clean; 
} 

和settings.php配置

<?php 
    $_defaults = array( 
     '_plugin_slug' => 'Knowledgebase', 
     '_article_qty' => 5, 
     '_search_setting' => 0, 
     '_breadcrumbs_setting' => 0, 
     '_sidebar_home' => 0, 
     '_sidebar_inner' => 0, 
     '_comments_setting' => 0, 
     '_bgcolor' => '' 
    ); 

    $_settings = wp_parse_args(get_option('_settings'), $_defaults); 
?> 

<form method="post" action="options.php"> 
<?php 
    settings_fields('_settings'); 
?> 
<input type="text" name="_settings[_plugin_slug]" id="_plugin_slug" value="<?php echo esc_attr($_settings['_plugin_slug']); ?>"> 

// Same other fields 

所以我在哪裏製作錯誤？

好的我得到了你的問題。像你的代碼做一些改變。

在index.php中刪除從BGCOLOR驗證

sanitize_hex_color(); 

Remeber此功能僅去除功能不全例如線

$_clean['_bgcolor'] = isset($input['_bgcolor']) ? sanitize_hex_color($input['_bgcolor']) : ''; 

要改變這種代碼

$_clean['_bgcolor'] = isset($input['_bgcolor']) ? $input['_bgcolor'] : ''; 

現在做一些改變的settings.php。形式

if(isset($_settings['update'])){ 
    unset($_settings['update']); 
      update_option('_settings', $_settings); 
} 

之前添加該代碼，並添加隱藏的輸入字段之前提交按鈕

<input type="hidden" name="_settings[update]" value="update" /> 

希望這將幫助你
