Question

我有两到三周的时间来使用Wordpress，我正在编写一个小型自定义系统作为基于wordpress的网站的插件。该系统读取一组json编码文件并将其显示为表格列表。

与我已经保存的一些基本设置一起，我想为这些json文件包含一个简单的文本编辑器，我想知道是否有一种方法可以为options.php脚本“附加”自定义操作处理表单提交，以便向其发送文件路径和内容。

我目前正在考虑写一些ajax，但我之前想在这里问，也许有一种简单的方法来实现这一点。

myplugin.php

function myplugins_menu(){
add_options_page('myplugin configuration','myplugin','manage_options', _
'myplugin_menu','myplugin_options');
//call register settings function
add_action( 'admin_init', 'register_mysettings' );
}

add_action('admin_menu','myplugin_menu');

function myplugin_options(){
    include('admin/myplugin-admin.php');
}


function register_mysettings() {
    //register our settings
    $setting_list=array('mail_title','mail_from','mail_to','recipient');
    foreach ($setting_list as $setting){
        register_setting( 'myplugin-settings-group', $setting );
    }
}

为myplugin-admin.php的

<div class="wrap">
<h2>My plugin</h2>
<h3>My plugin Options</h3>

<form method="post" action="options.php">
<?php settings_fields( 'myplugin-settings-group' ); ?>
<?php do_settings_sections( 'myplugin-settings-group' ); ?>
<table class="form-table">
    <?php
    print_option('Mail Subject','mail_title');
    print_option('Sender address','mail_from');
    print_option('Recipient address','mail_to');
    print_option('Recipient name','recipient');
    ?>
</table>
<?php submit_button(); ?>
</form>

</div>

<?php
    echo "<select name=\"filename\" size=\"1\">";
    $dir = plugin_dir_path( __FILE__ );
    $files = glob($dir."../services/*.json");
    foreach ($files as $filename){
        echo "<option value=\"".basename($filename)."\">".basename($filename)."</option>";
    }
    echo "</select>";

    $dir = plugin_dir_path( __FILE__ );
    $file = file(WP_PLUGIN_DIR."/myplugin/services/010.Luftansa.json");
    echo "<form action=\"".$_SERVER['PHP_SELF']."\" method=\"post\">";
    echo "<textarea Name=\"update\" cols=\"50\" rows=\"10\">";
    foreach($file as $text) {
        echo $text;
    } 
    echo "</textarea>";
    echo "<input name=\"Submit\" type=\"submit\" value=\"Update\" />\n
    </form>";
}

在上面的代码段中，我将_SERVER['PHP_SELF']作为表单的操作，但这会转换为/wp/wp-admin/options-general.php;。

如果我将路径放到我的管理文件中，除了通过http-refresh之类的东西，我就无法返回管理界面。
