删除按钮和确认 [英] Delete button and confirmation

问题描述

你好我有一个工作链接从我的数据库中删除一行。

 < a href =？action = delete& id =< ;? echo $ id？> '）>< strong>删除此案例< / strong>< / a>< / td> onclick =return confirm（'您确定要删除吗？ 
<？php 
 if（$ _ POST ['action'] ==delete）
 {
 $ id = $ _POST ['id']; 
 
 mysql_query（DELETE FROM rmstable2 WHERE id ='$ id'）; 
 echo（> Case＃$ id已被删除，要查看您的更改，请点击< a href ='/ martinupdate.php？id = $ id'> here< / a>< / b个;<峰; br>中）; 
} 
？> 
  

我正在寻找的是一个链接，而不是我想要的按钮它带来了一个确认，然后删除该行如果是true。

我不希望意外删除。

 <形式> 
< input type =buttonvalue =删除此案例onclick =return confirm（'您确定要删除？'）; 
< a href =？action = delete& id =< ;? echo $ id？>> 
< / form> 
  

解决方案

在文件顶部试试这个：

 <？php 
 
 if（$ _SERVER ['REQUEST_METHOD'] =='DELETE'|| （$ _SERVER ['REQUEST_METHOD'] =='POST'&& $ _POST ['_ METHOD'] =='DELETE'））{
 $ id =（int）$ _POST ['id']; 
 $ result = mysql_query（'DELETE FROM rmstable2 WHERE id ='。$ id）; 
 if（$ result！== false）{
 //无法返回200响应并显示不同的资源，因此重定向。 303表示看到其他页面，并不表示资源已经移动。 
 header（'Location：http：//fully-qualified-url/martinupdate.php？id ='。$ id，true，303）; 
出口; 
 
 
 
 
 
 
 $ b 
以这种形式：
 < form method =POSTonsubmit =return confirm（'您确定要删除此案例吗？'）;> 
< input type =hiddenname =_ METHODvalue =DELETE> 
< input type =hiddenname =idvalue =<？php echo $ id;？>> 
< button type =submit>删除个案< / button> 
< / form> 
  
 
Hi I have a working link to delete a row from my database. 
<a href="?action=delete&id=<? echo $id ?>" onclick="return confirm('Are you sure you want to delete?')"><strong>Delete this Case</strong></a></td>
<?php
    if($_POST['action']=="delete")
    {
         $id = $_POST['id'];

         mysql_query("DELETE FROM rmstable2 WHERE id= '$id'");
         echo("> Case # $id has been deleted as requested. To see your changes please click <a href='/martinupdate.php?id=$id'>here</a></b><br>");
    }
?>
what I am looking to do is instead of having a link I want to have a button that when pressed it brings up a confirmation and then deletes the row if true.

I do not want accidental deletions.
<form>
    <input type="button" value="Delete this Case" onclick="return confirm('Are you sure you want to delete?')"; 
    <a href="?action=delete&id=<? echo $id ?>">
</form>

解决方案
Try this at the top of your file:
<?php

if ($_SERVER['REQUEST_METHOD'] == 'DELETE' || ($_SERVER['REQUEST_METHOD'] == 'POST' && $_POST['_METHOD'] == 'DELETE')) {
    $id = (int) $_POST['id'];
    $result = mysql_query('DELETE FROM rmstable2 WHERE id='.$id);
    if ($result !== false) {
        // there's no way to return a 200 response and show a different resource, so redirect instead. 303 means "see other page" and does not indicate that the resource has moved.
        header('Location: http://fully-qualified-url/martinupdate.php?id='.$id, true, 303);
        exit;
    }
}
With this as the form:
<form method="POST" onsubmit="return confirm('Are you sure you want to delete this case?');">
    <input type="hidden" name="_METHOD" value="DELETE">
    <input type="hidden" name="id" value="<?php echo $id; ?>">
    <button type="submit">Delete Case</button>
</form>
