如何使我的 wordpress 插件重定向以形成成功页面或失败页面

Question

我创建了一个插件，可以将数据插入我的本地数据库。但是提交后，我想重定向到成功页面或不成功页面或重复记录页面。下面是我的插件代码。当点击提交时，数据库插入工作得很好，但我收到重定向页面的 404 错误。 php、apache 或 mysql 日志中也没有错误。

<?php
/*
plugin name: deano plugin
description: deano test database to insert data into books table
author: Dean-O

*/
$path = preg_replace('/wp-content.*$/', '', __DIR__);
require_once($path.'/wp-load.php');
function deanoinsertdata() {
/**
* Dean-O database insert book function
*/
global $wpdb;
if(isset($_POST['submitbtn'])){
    $data=array(
        'wp_id'=>$_POST['wp_id'],
        'title'=>$_POST['title'],
        'author'=>$_POST['author'],
    );
    $table_name = 'books';
    $foundOne = 1;

    $wp_idin = $_POST['wp_id'];
    $titlein = $_POST['title'];
    $authorin = $_POST['author'];

    /*echo ($wp_idin);
    echo ($titlein);
    echo ($authorin);
    */

    /*
    see if the record is already in the table
    */
    $sql = "select * from books"; 
    print $sql;
    $results = $wpdb->get_results($sql);
    foreach($results as $result) {
        if($result->wp_id==$wp_idin && $result->title==$titlein && $result->author==$authorin)
        {
            $foundOne = 0;
        }
    }

    if($foundOne==1) {
        $resultinsert = $wpdb->insert($table_name,$data, $format=NULL);
        if($resultinsert==1) {
             //header('Location: http://localhost/tadpolewp/deano-plugin-successful/'); 
            error_log( 'successful' );
             wp_redirect( "http://localhost/tadpolewp/deano-plugin-successful/", 301 );
            //error_log('Book saved 1');
            //echo "Book Saved 1";
        } else {
            //header('Location: http://localhost/tadpolewp/deano-plugin-failed/'); 
            error_log( 'failed to save' );
            wp_redirect( "http://localhost/tadpolewp/deano-plugin-failed/", 301 );
            //error_log('unable to save');
            //echo "Unable to Save";
        }
    } else {
        //error_log('Duplicate record found');
        //echo "Duplicate recortd found";
        //header('Location: http://localhost/tadpolewp/deano-plugin-duplicate-records/');
        error_log( 'duplicate record' );
        wp_redirect( "http://localhost/tadpolewp/deano-plugin--duplicate-records/", 301 );

    }

我的错...我忘记了 exit();每次重定向后。问题解决了。
