我目前正在尝试为wordpress构建一个插件来构建设置页面。但由于某种原因，当我使用add_action("admin_init", array(class_object, \'function_name\')) 它将运行add\\u action函数，但不会访问回调。它只是跳过了它。

我试着用与主类相同的方式创建一个包含1个函数的测试类，这确实有效。所以我在某处做了一些不同的事情，但我不知道是什么。

这是代码。我已经将代码拆分为3个不同的文件，我将按包含文件的顺序发布它。

Index file for the plugin

include(\'admin/options.php\');


function social_share_menu_item() {
    add_submenu_page("options-general.php", "Social Share", "Social Share", "manage_options", "social-share", \'socialShareOptions\');
}
add_action("admin_menu", "social_share_menu_item");

...

options.php

include_once(\'settings/SocialOptions.class.php\');

function socialShareOptions(){

    $options = array(
        array(
            \'type\'  => \'checkbox\',
            \'name\'  => \'social-share-facebook\',
            \'value\' => 1,
            \'title\' => \'Show Facebook \'
        ),
        array(
            \'type\'  => \'checkbox\',
            \'name\'  => \'social-share-twitter\',
            \'value\' => 1,
            \'title\' => \'Show Twitter\'
        ),
        array(
            \'type\'  => \'checkbox\',
            \'name\'  => \'social-share-instagram\',
            \'value\' => 1,
            \'title\' => \'Show instagram\'
        )
    );

    $socialOptions = new SocialOptions($options);
    $socialOptions->buildSettingsPage();
    add_action("admin_init", array($socialOptions, \'setOptions\') );
}

SocialOptions.class.php

class SocialOptions {

    private $_optionsArray;

    function __construct( $options = array() ) {

        $this->_optionsArray = $options;

    }

    public function setOptions() {

        add_settings_section("social_share_config_section", "", null, "social-share");

        foreach ( $this->_optionsArray as $option) {
            add_settings_field("social-share-facebook", $option[\'title\'], array($this, \'option\'), "social-share", "social_share_config_section", $option);
        }
        foreach ( $this->_optionsArray as $option) {
            register_setting("social_share_config_section", $option[\'name\']);
        }
    }

    public function option( $fieldData ){
        ?>
        <input type="<?php echo $fieldData[\'type\'] ?> " name="<?php echo $fieldData[\'name\']; ?>" value="<?php echo $fieldData[\'value\'] ?>"<?php checked(1, get_option($fieldData[\'name\']), true)?> /><?php echo $fieldData[\'title\'] ?>
        <?php
    }


    public function buildSettingsPage() {

        $html = \'<div class="wrap social-admin-style">

                    <div class="title">
                        <h1>Social Sharing Options</h1>
                    </div>

                    <div class="main-content">

                        <form method="post" action="options.php">

                            \' . settings_fields("social_share_config_section") . \' 

                            \' . do_settings_sections("social-share") . \'

                            \'. submit_button() . \'

                        </form>

                    </div>

                </div>\';

        echo $html;

    }


}

当我创建以下内容时，效果很好：

options.php

include_once(\'settings/SocialOptions.class.php\');

class Test {
    function testing(){
     return \'nothing\';
    }
}

function socialShareOptions(){

    $options = array(
        ...
    );

    $socialOptions = new SocialOptions($options);
    $socialOptions->buildSettingsPage();

    /*NOTE THIS PART*/
    $test = new Test();
    add_action("admin_init", array($test, \'testing\') );
}

Additional information

include_once(\'settings/SocialOptions.class.php\');

$options = array(
    ...
    )
);
$socialOptions = new SocialOptions($options);
add_action("admin_init", array($socialOptions, \'setOptions\'));

function socialShareOptions(){
    global $socialOptions;

    $socialOptions->buildSettingsPage();
}
