Question

我有HTML和PHP代码如下：

HTML

<a href="deleteData.php?id=<?php echo $value['id']?>"><button name="delte" class="btn">Delete</button></a>

deleteData.php

<?php
include ('include/connectdb.php');
$getid = $_GET['id'];
$sql = ("UPDATE tblworkfaire SET status=0 where id = ".$getid);
$res = mysql_query($sql) or die (mysql_error());

?>

除了删除记录后，记录仍然显示在页面上直到刷新，这样做很有效。如何修复此问题。任何人都有任何想法可以帮助我。谢谢，

Answer 1

尝试这样的事情---

jQuery.ajax({
        type: "GET",
        url: deleteData.php,
        data:{'id':id},
        success:function(results)
        {   
                 .....
        }
        });

Answer 2

您应该使用Ajax。尝试使用jQuery：
http://api.jquery.com/jQuery.ajax/

然后onSuccess方法也使用jQuery删除行。

Answer 3

以下是删除记录的完整源代码而不刷新页面。

按照步骤

<强>步骤1：

DBConnect.php

  class DBConnect
  {
    function DBConnect()
    {
       $link= mysql_connect("localhost","root","")or die("Local Host Error".mysql_error());
       mysql_select_db("test");
    }

    function viewData()
    {
      $query = "SELECT * FROM test_mysql";
      $resultset = mysql_query($query);
      return $resultset;
    }

    function DeleteData($userID)
    {
      $query = "DELETE FROM test_mysql WHERE id=".$userID;
      $resultset=mysql_query($query) ;
    }
  }

<强>步骤2：
 delete.php

   include_once'DBConnect.php';    
   if(isset($_REQUEST['userid']) && $_REQUEST['userid'])    
   {    
     $delObj= new DBConnect();    
     $delObj->DeleteData($_REQUEST['userid']);    
   }

第3步：
 index.php

    <html>
    <head>
    <title></title>
    <script type="text/javascript">
    function deletedata(id)
    {
      var xmlhttp;    
      if (id=="")
        {
            document.getElementById("Display").innerHTML="";
            return;
        }
      if (window.XMLHttpRequest)
        {// code for IE7+, Firefox, Chrome, Opera, Safari
            xmlhttp=new XMLHttpRequest();
        }
      else
      {// code for IE6, IE5
            xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
      }
      xmlhttp.onreadystatechange=function()
      {
            if (xmlhttp.readyState==4 && xmlhttp.status==200)
            {
              window.location.reload()

            }
      }
          xmlhttp.open("GET","delete.php?userid="+id,true);
          xmlhttp.send();

    }
    </script>
    </head>
    <body>
    <?php 
    include 'DBConnect.php';
    $ViewObj= new DBConnect();
    $ResultSet=$ViewObj->viewData();
    ?>
    <span id ="Display">
    <table align="center" border="1" width="50%" cellpadding="4" cellspacing="4">
    <tr>
      <th>ID</th>
      <th>Name</th>
      <th>operation</th>
      <th align="center">Action</th>
    </tr>
    <?php
    while($row= mysql_fetch_array($ResultSet))
    {
    ?>
    <tr>
      <td><?php echo $row[0];?></td>
      <td><input type="text" name="txt"></td>
      <td><?php echo $row[1];?></td>
      <td align="center"><a href="#" onClick="deletedata('<?php echo $row[0];?>')" style="color:#00F"><b>Delete</b></a></td>
    </tr>
    <?php
    }
    ?>
    </table>
    </span>
    </body>
    </html>

如果您感觉有任何问题，请告诉我。我们会帮助您。谢谢。

Answer 4

使用重定向（'my_original_page.php'）它会重定向到您的主页，但应该在删除查询被执行后放置

Answer 5

你必须为此使用AJAX

使用本教程

Deleting values from MySQL database with AJAX without page reload (edited)

它会帮助你。

Answer 6

Creaet Delete.php文件

 include_once'DBConnect.php';
 if(isset($_REQUEST['userid']) && $_REQUEST['userid'])
 {
 $delObj= new DBConnect();
 $delObj->DeleteData($_REQUEST['userid']);
 }

创建DBConnect.php文件

<?php

class DBConnect
{
function DBConnect()
{
    $link= mysql_connect("localhost","root","")or die("Local Host Error".mysql_error());
    mysql_select_db("mydb");

}

 function viewData()
{

    $query="select * from userinfo";
    $resultset=mysql_query($query) ;

    return $resultset;


}

function DeleteData($userID)
{

    $query="DELETE from userinfo where id=".$userID;

    $resultset=mysql_query($query) ;

}


}

?>

创建index.php文件

<script>
function deletedata(id)
{
    var xmlhttp;    
    if (id=="")
      {
          document.getElementById("Display").innerHTML="";
          return;
      }
    if (window.XMLHttpRequest)
      {// code for IE7+, Firefox, Chrome, Opera, Safari
          xmlhttp=new XMLHttpRequest();
      }
    else
    {// code for IE6, IE5
          xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
    }
    xmlhttp.onreadystatechange=function()
    {
          if (xmlhttp.readyState==4 && xmlhttp.status==200)
          {
            window.location.reload()

          }
    }
        xmlhttp.open("GET","delete.php?userid="+id,true);
        xmlhttp.send();

}
</script>    




<?php include 'DBConnect.php';
$ViewObj= new DBConnect();
$ResultSet=$ViewObj->viewData();?> // I have created one function which will get all the data from the database if you don't want to do this just call deletedata() function onClick event and pass Record ID as agrument which you want to delete on DELETE button.
<br /><br /><br />
<span id ="Display">
<table align="center" border="1">
<tr>
      <th>Name</th>
      <th>operation</th>
</tr>
<?php
while($row= mysql_fetch_array($ResultSet))
{?>


<tr>
    <td><input type="checkbox"></td>
    <td><?php echo $row[1];?></td>

    <td align="center"><a href="#" onclick="deletedata('<?php echo $row[0];?>')" style="color:#FF0000"><b>Delete</b></a>

    </td>
</tr>

<?php 


}
?>
</table>

我认为这会对你有所帮助:)。

你可以使用php函数 header（'location：yourPage.php'）; 或者在Ajax的帮助下使用。
