插件设置值未保存wordpress

Question

我正在进行插件设置。首先，我以正常的方式保存插件设置，它完美地工作

这是我的旧代码：

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');
}

以及设置.php

<?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，但现在我更改代码以注册设置并调用其值，但它不起作用，每当我保存值时，它都会在我提交表单后显示一个空白页。

这是我的新代码：

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;
}

以及设置.php

<?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

那么，我在哪里犯错误呢？

好的，我明白你的问题了。在代码中做一些更改，比如。

在index.php中，从bgcolor验证中删除此函数

sanitize_hex_color();

Remember remove only function not complete line例如

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

更改此代码

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

现在在settings.php中做一些更改。在表单之前添加此代码

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

并在提交按钮之前添加隐藏的输入字段

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

希望这将帮助您
