在PHP中连续删除记录 [英] DELETE record in a row in PHP

问题描述

我试图删除我的数据库中的记录。所以基本上我创建了一个包含我所有记录的表格。现在我需要做的是当我点击DELETE链接时，它会删除记录选定的行。

I was trying to delete a record on my Database. So basically I created a table that contains all of my records. Now what I need to do is when I click on the "DELETE" link it would delete the record selected row.

下面是它的样子：

所以基本上我在这里有3页。

1. page.php

2. add.php

3. delete.php

So basically I have 3 pages here.
1. page.php
2. add.php
3. delete.php

这是我的page.php文件：

Here's my page.php file:

<table border="1">
    <thead>
        <th>email</th>
        <th>date</th>
        <th>delete</th>
    </thead>

    <tbody>
        <tr>
        <?php 
            foreach($emails as $mail){ ?>
            <td><?php echo $mail['email']; ?></td>
            <td><?php echo $mail['date']; ?></td>
            <td><?php echo "<a href='delete.php?id=". $mail['id']. "'>DELETE</a>"; ?></td>
        </tr>
            <?php } ?>


    </tbody>
</table>

这是我的add.php文件：

Here's my add.php file:

<?php
    require("new-connection.php");

    session_start();

    $email = $_POST['email'];
    if(empty($_POST['email']) AND (filter_var($email, FILTER_VALIDATE_EMAIL) === false))
     {
          $_SESSION['message'] = "email cannot be blank";
     }else{
        $query = "INSERT INTO email_tbl (email, date)
              VALUES('$email', NOW())";       

    $insertEmail = run_mysql_query($query);


    if(run_mysql_query($query))
    {
        $_SESSION['message'] .= "New RECORD has been added correctly!";
    }
    else
    {
        $_SESSION['message'] .= "Failed to add new Interest"; 
    }

    }


    header('Location: email.php');




?>

以下是我的delete.php文件：

Here's my delete.php file so far:

<?php
    require("new-connection.php");

    session_start();


    $query = "DELETE FROM email_tbl
            WHERE id={id} LIMIT 1";       

    $deleteEmail = run_mysql_query($query);


    if(run_mysql_query($query))
    {
        $_SESSION['message'] .= "RECORD has been DELETED correctly!";
    }
    else
    {
        $_SESSION['message'] .= "Failed to DELETE RECORD"; 
    }



    header('Location: email.php');




?>

现在，当我单击删除链接时，它必须实时删除按钮。任何想法？

So now when I click the delete link it must delete the button real time. Any idea?

推荐答案

修改您的delete.php以检索url参数：

Modify your delete.php to retrieve the url parameter:

<?php
    require("new-connection.php");
    session_start();

    $id = $_GET['id'];

    $query = "DELETE FROM email_tbl
            WHERE id='$id' LIMIT 1";       

    $deleteEmail = run_mysql_query($query);


    if($deleteEmail)
    {
        $_SESSION['message'] .= "RECORD has been DELETED correctly!";
    }
    else
    {
        $_SESSION['message'] .= "Failed to DELETE RECORD"; 
    }

    header('Location: email.php');
?>

至于你的add.php，你正在使用这个：

As for your add.php, you are using this:

$insertEmail = run_mysql_query($query);

    if(run_mysql_query($query))

您应该将其更改为这个：

You should change it to this:

$insertEmail = run_mysql_query($query);


    if($insertEmail)

你在做什么现在你通过调用run_mysql_query两次来执行查询两次。这应该解决它

What you are doing right now is you are executing the query twice by calling run_mysql_query twice. This should fix it
