PHP数据库更新功能只修改了第一行？

editcrew.php

handlecrewedit.php

这是我修改条目的另一个问题。我不太确定我是否可以简单地复制和粘贴我的删除代码来编辑代码，但这里是我的表的一些粗略估计。与删除功能不同，通过选择编辑功能，它将用户引导到表单页面，并要求他们填写更新的数据。

错误

缺少结束标记？>此处将editcrew.php和handlecrewedit.php文件代码替换为以下代码

editcrew.php

handlecrewedit.php

我认为建议的答案遗漏了一点。 它只更新第一行，因为您使用重定向头退出while循环

<?php
require 'dbfunction.php';
$con = getDbConnect();
$crew_id = $_POST["crew_id"];
$CrewName = $_POST["CrewName"];
$CrewRank = $_POST["CrewRank"];
$StartDate = $_POST["StartDate"];
$EndDate = $_POST["EndDate"];
$PayrollNo = $_POST["PayrollNo"];
$EmployeeNo = $_POST["EmployeeNo"];
$WatchKeeping = $_POST["WatchKeeping"];
$Active = $_POST["Active"];

if (!mysqli_connect_errno($con)) {
    $sqlQueryStr = "UPDATE crewlist SET crew_name = '$CrewName', crew_rank = '$CrewRank', start_date = '$StartDate' "
            . ", end_date = '$EndDate', payroll_no = '$PayrollNo'"
            . ", employee_no = '$EmployeeNo', watchkeeping = '$WatchKeeping', active = '$Active' WHERE crew_id = " . $crew_id . "";
    mysqli_query($con, $sqlQueryStr);
}
header('Location: crewlisting.php');
mysqli_close($con);
?>

将这两行放在while循环之外，它将更新每一行

您的while循环将比：

header('Location: crewlisting.php');
mysqli_close($con);

@Kausha Mehta在这里！对不起，我是新来的，没关系。我给出了解决方案，请查看。@KaushaMehta您好，我有一个关于搜索功能的新查询。我的主页显示所有用户的记录，如何使搜索文本框读取我键入的内容，例如，当我键入“J”时，记录自动刷新为以“J”开头的名称。提前谢谢。如果你在这里创建新的问题和链接会更好。无论你们在新问题中尝试了什么，我都会解释你们的代码，然后我就能解释了。@KaushaMehta我已经有了一个，但谢谢！我会有更多的疑问：很抱歉，我在这里传输时漏掉了它，我会编辑它。很抱歉，但是你能解释更多关于第四个错误的信息吗，因为我相对较新。谢谢你向我解释这些小细节！这有帮助！我会稍后再查看。我已经添加了if-！mysqli_connect_errno$con{$queryStr=SELECT crew_id.FROM crewlist；}$result=mysqli_query$con，$queryStr；-上面的代码，它可以工作，但它更新了整个表。否则就不行了，再次谢谢！我会稍后再试，然后再告诉你@陈俊浩好的，好的，一旦你添加了，请告诉我。嗨@Kausha Mehta，我试过了，但是你的代码不起作用。当我将下面的代码与您的代码合并时，它会更新整个表。只是为了澄清，它需要$queryStr=从crewlist中选择crew\u id才能工作。@陈俊浩不，这不是必需的，因为在editcrew.php中，我在hidden中使用crew\u id字段，所以我在handlecrewedit.php中得到了类似于$\u POST的字段。
