单个php文件中的多个表单

标签： php mysql forms

我目前正在开发一个PHP CMS，我正在尝试为新闻系统创建一个编辑页面。

当用户进入编辑页面并且尚未选择文章时，他们应该获得一个表单来选择要编辑的文章。

当用户选择要编辑的文章时，页面应该（刷新？）显示包含要编辑的所选文章内容的表单。

我的所有网页都包含在我的index.php中，基于p = pagename设置。

当我进入编辑新闻页面时，我看到http://puu.sh/fhYO7/569146d037.png（这是正确的）。

当我选择要编辑的新闻文章时，请将我发送到http://puu.sh/fhZ13/2ca0f7d974.png，其网址为：mysite.com/admin/editnews.php？id = 4

如果我手动输入URL应该是什么：mysite.com/admin/index.php?p=editnews&id=4我得到了这个 - http://puu.sh/fhZ6h/d38e97d0bb.png

我当前的代码： editnews.php 

<?php
    ob_start();
    session_start();

    include_once('includes/connection.php');
    include_once('includes/news.php');

    $news = new AdminNews;

    if (isset($_SESSION['logged_in'])) {
        $newss = $news->fetch_all();

        if (isset($_POST['title'], $_POST['content'])) {
            $title = $_POST['title'];
            $content = br2nl($_POST['content']);

            if (empty($title) or empty($content)) {
                $error = 'All fields are required!';
                header('Location: index.php?p=editnews');
            } else {
                global $pdo;

                $query = $pdo->prepare('UPDATE admin_news SET news_title = ?, news_content = ? WHERE news_id=?');
                $query->bindValue(1, $title);
                $query->bindValue(2, $content);
                $query->bindValue(3, $id);

                $query->execute();

                header('Location: index.php');
            }
        }

        if (isset($_GET['id'])) {
            $id = $_GET['id'];
    ?>
    <!-- POST -->
    <div class="post">

    <!-- POST -->
    <?php

    } else {
        header('Location: index.php');
    }

    ?>

我完全迷失在这一点上（距离它已经10年多了之后才重新开始使用PHP）。

问题是： 我做错了什么，为什么它不会把我发送到正确的网址，为什么当我输入网址时它会显得很奇怪？

您有两种选择：
1.获取表单以发布到index.php而不是editnews.php并处理index.php中的数据。换句话说改变：

<form action="editnews.php" method="post" autocomplete="off">

为：

<form action="index.php" method="post" autocomplete="off">
  1. 使用ajax提交表单而不刷新页面。这意味着您必须在javascript中处理按钮单击并使用ajax调用url editnews.php处理表单

    2. 在jquery中，可以这样做：

    $("#myForm").submit(function() {
    $.post('editnews.php', 
    {
        title: $('#name').val(), 
        content: $('#content').val()
    }, 
    function(data) {
        console.log(data); //response
        $('#name, #content').val(''); /* Clear the inputs */
    }, 
    'text');
    return false; //Stop form from refreshing page
});

你应该尝试在开头写一个斜杠：

header('Location: /index.php?p=editnews');

干杯！

答案 2 :(得分：0)

我终于想出了一个解决方案（它只用了FOREVER）......

首先我所做的是删除了新闻选择表单，只是将选择内容转换为链接标题列表，这些标题会将您带到与＆amp; id =＃的正确链接。

然后我更改了检查以查看是否设置了ID，如果是，则显示要编辑的表单（表单显示错误，因为缺少“和;在我的表单中。” / p>

固定代码： 

<?php
ob_start();
session_start();

include_once('includes/connection.php');
include_once('includes/news.php');
include_once('includes/functions.php');

$news = new AdminNews;
$funct = new UserFunctions;

if (isset($_SESSION['logged_in'])) {
    $newss = $news->fetch_all();

    if (isset($_POST['title'], $_POST['content'])) {
        $title = $_POST['title'];
        $content = nl2br($_POST['content']);

        if (empty($title) or empty($content)) {
            $error = 'All fields are required!';
            header('Location: index.php?p=editnews');
        } else {
            global $pdo;

            $query = $pdo->prepare('UPDATE admin_news SET news_title = ?, news_content = ? WHERE news_id=?');
            $query->bindValue(1, $title);
            $query->bindValue(2, $content);
            $query->bindValue(3, $id);

            $query->execute();

            header('Location: index.php');
        }
    }

    if (isset($_GET['id'])) {
        $id = $_GET['id'];

        $query = $pdo->prepare("SELECT * FROM admin_news WHERE news_id = ?");
        $query->bindValue(1, $id);
        $query->execute();

        $rows = $query->fetchAll();

        //set username to variable
        foreach ($rows as $row) {
            $id = $row['news_id'];
            $title = $row['news_title'];
            $content = $funct->br2nl($row['news_content']);
        }
