Php 使用复选框从表中获取多行并将其添加到另一个表中，然后从上一个表中删除
在我的管理员页面中，将显示希望注册到该网站的人员列表 请求被插入到myPhp 使用复选框从表中获取多行并将其添加到另一个表中，然后从上一个表中删除,php,mysql,checkbox,Php,Mysql,Checkbox,在我的管理员页面中，将显示希望注册到该网站的人员列表 请求被插入到myMembersNedReg表中。当用户被接受时，用户的行将移动到members表中 在从membersneedreg获取数据时，我在每行添加了一个复选框，并决定将$num变量作为其值，该值在每个循环中递增 我的问题是，系统如何确认选中了我的复选框，在提交时，所选数据行将从membersNedReg表移动到members表中 我们将非常感谢您的帮助。如果您对我的帖子有任何疑问或需要修改，请随时发表评论 <?php $r

让我们首先将您的MySQL转换为MySQLi。我将在注释/***/中进行一些解释，然后继续讨论代码
如果你想听听我的建议，你应该创建2个表，而不是2个数据库。（根据您的解释，您将membersneedreg
和members
称为数据库）。
假设您的membersneedreg
和成员是表，它们都有相同的列
例如，您可以将其保存为form.php：
<?php
/* ESTABLISH THE CONNECTION */
$con=mysqli_connect("YourHost","YourUsername","YourPassword","YourDatabase"); /* REPLACE THE NECESSARY HOST, USERNAME, PASSWORD, AND DATABASE */
if(mysqli_connect_errno()){
echo "Error".mysqli_connect_error();
}
$result_set = mysqli_query($con,"SELECT * FROM membersneedreg");
$num_messages = mysqli_num_rows($result_set);
echo "<table border='1' align='center'>";
echo "<tr><th>MemberID</th><td>FirstName</td><td>LastName</td><td>Date of birth</td><td>Email</td><td>Address</td><td>PostCode</td><td>UserName</td><td>Password</td><td>Annadale Relationship</td></tr>";
/* FETCH THE DATA BASED ON THE QUERY RESULT_GET */
$num=0; /* THIS WILL BE SET AS YOUR COUNTER */
while($row = mysqli_fetch_array($result_set)){
$memberid1 = $row['MemberID'];
$fname1 = $row['FirstName'];
$lastn1 = $row['LastName'];
$DOB1 = $row['Date_of_Birth'];
$Email1 = $row['Email'];
$Address1 = $row['Address'];
$Postcode1 = $row['PostCode'];
$UserName1 = $row['UserName'];
$Password1 = $row['Password'];
$relationship1 = $row['Annadale_Relationship'];
$num++; /* INCREMENT NUM */
echo "<form action='confirm_mem.php' method='POST'>";
echo "<tr align='center'><th>$memberid1</th>";
echo "<td>$fname1</td>";
echo "<td>$lastn1</td>";
echo "<td>$DOB1</td>";
echo "<td>$Email1</td>";
echo "<td>$Address1</td>";
echo "<td>$Postcode1</td>";
echo "<td>$UserName1</td>";
echo "<td>$Password1</td>";
echo "<td>$relationship1</td>";
echo "<td><input type='checkbox' name='member[$num]' value='$memberid1'></td></tr>";
/* THIS IS IMPORTANT, YOU SHOULD PUT TO AN ARRAY THE VALUE OF THIS CHECKBOX, AND THE VALUE WILL BE BASED ON THE FETCH ARRAY. IN MY EXAMPLE, THE $memberid1 VARIABLE */
}
echo "</table>";
echo "<input type='hidden' name='hiddencounter' value='$num'>"; /* THIS IS FOR THE COUNTING PURPOSES */
echo "<input type='submit' name='submit' value='Add Member'>";
echo "</form>";
?>
不要使用mysql \*-它已弃用，请使用PDO
或MySQLi
我根据我的连接添加并更改了它，但不幸的是，我仍在恢复confirm_mem页面上的4-6个未定义索引和变量错误。注意：未定义索引：第14行调用堆栈#时间内存函数位置1 0.0106 258352{main}（）..\confirm_mem.php:0（！）注意：未定义索引：C:\wamp\www\FinalProject\Webpages\confirm_mem.php中的成员在第15行调用堆栈上#时间内存函数位置10.0106 258352{main}（）..\confirm_mem.php:0（！）注意：未定义变量：x在C:\wamp\www\FinalProject\Webpages\confirm_mem.php在第17行调用堆栈上#时间内存函数位置1 0.0106 258352{main}（）..\confirm_mem.php:0（！）注意：未定义变量：x在C:\wamp\www\FinalProject\Webpages\confirm_mem.php第19行调用堆栈#时间内存函数位置1 0.0106 258352{main}（）..\confirm_mem.php:0（！）注意：未定义的变量：C:\wamp\www\FinalProject\Webpages\confirm_mem.php中的x在第17行调用堆栈#时间内存函数位置1 0.0106 258352{main}（）..\confirm_mem.php:0@akirk541用此for替换for循环(x元=0 ;$x@akirk541你可以试试我更新的答案，它是一个两个文件，第一个保存到form.php，第二个保存到confirm_mem.php
