Question

美好的一天！

我想问一些问题。我有一个名为＆＃34;删除＆＃34;的链接在索引文件中。现在，我想在执行删除操作之前从用户确认。但是，我想将脚本确认为删除文件。我尝试了多种方式，但它没用。但它实际上可以删除，我的问题正是如此，确认框没有提示。还挺＆＃39;在这里库存。请帮忙。

继承我在index.php的代码（链接到删除）：

`<p><strong>Country: </strong> <?php echo $country['countries'];?> &nbsp | 
&nbsp <a href="editcountry.php?id=<?php echo $country['id']; ?>">Edit</a> | 
<a href="deletecountry.php?id=<?php echo $country['id']; ?>" 
class="confirmation">Delete</a></p>`

这是我的delete.php文件：

`<?php
require 'dbconnect.php';
$id = $_GET['id']; ?>

<script>
    function confirmationDelete(){
    var conf = confirm('Are you sure want to delete this record?');
        if(conf==true){
            <?php
                $sql = "DELETE countries FROM countries WHERE id=$id";
                if (mysqli_query($connect, $sql)) { ?>
                    alert("Record Deleted!");
                <?php }
                else { ?>
                    alert("Error Deleting Record!");
                <?php } ?>
        }
   return conf;
    }
</script>`

Answer 1

在

<a href="deletecountry.php?id=1" onclick="return confirm('Are you sure you want to delete this record?')" class="confirmation">Delete</a>

然后在你的deletecountry.php

中

<?php
session_start();
require 'dbconnect.php';
$id = $_GET['id']; ?>
$sql = "DELETE countries FROM countries WHERE id=$id";
if (mysqli_query($connect, $sql)) {
    $_SESSION['msg'] = 'Successfully Deleted';
}
else {
    $_SESSION['msg'] = 'Error Deleting';
}
// redirect to somewhereelse.php

然后在你的somewhereelse.php

<?php
session_start();
if(isset($_SESSION['msg']))
{
    echo '<script>alert("'. $_SESSION['msg'] .'")</script>';
    session_unset('msg');
}
?>

Answer 2

    <a onclick='javascript:confirmationDelete($(this));return false;' href="delete.php?id=1">Delete</a>

    and create javascript function

    function confirmationDelete(anchor)
    {
      var conf = confirm('Are you sure want to delete this record?');
       if(conf)
          window.location=anchor.attr("href");
    }
                or
<a href="delete.php?id=1" onClick=\"javascript:return confirm('are you sure you want to delete this?');\">delete</a>

工作？如何在点击链接后在另一页上打开确认框？
