Question

好吧这是现在更新的主要php页面，香港专业教育学院清除了我以前的帖子，使其干净，仅供参考...我在这里发布的帖子只是我的测试页面，这是我的实际页面的精确复制品。只是有不同php页面名称......

include 'include/DB_Close.php';
?>

现在查看我建议和创建的第3个php页面...如果您在代码中看到任何错误，请更正：

最新更新删除php：

<?php
require 'include/DB_Open.php';

$id = $_POST['id'];
$idtodelete = "'" . implode("','",$id) . "'";

$query = "DELETE FROM tbl_main WHERE ars_no in (" . $idtodelete . ")";
$myData = mysql_query($query);

include 'include/DB_Close.php';
?>

感谢所有的帮助...：）

Answer 1

首先要注意的是，请在提交按钮（例如“操作”）上提供相同的名称，并在提交后在服务器端检查值：if ($_POST['action'] == 'Retrieve List') {} else if ($_POST['action'] == 'Delete from DB')

第二个问题，复选框的名称是关键：

<input type="checkbox" name="checkbox[]" value="{$info['ars_no']}"/>

然后在服务器端：

foreach($_POST['checkbox'] as $checkbox) {}

Answer 2

您需要做的是使用提交按钮名称处理更新和删除操作。您需要做的是创建两个具有相同名称但值不同的提交按钮。

这是你的表格：

<form action="" method="post">
    <input name="action" type="submit" id="RetrieveList" value="RetrieveList" />
    <input name="action" type="submit" id="DeletefromDB" value="DeleteFromDB" />
    <input name="Clear" type="reset" id="Clear" value="Clear" />
</form>

我为两个action按钮指定了同名submit。提交此表单后，您可以检查服务器端的$_POST['action']。

你可以这样做：

if ($_POST['action'] == 'RetrieveList') {
    //retreive list functionality
} elseif ($_POST['action'] == 'DeleteFromDB') {
    //delete from dB functionality.
}

<强>更新

您需要像这样更改表单：

echo "<form action='resultgenerator.php' method='post'>";
    echo '<input name="action" type="submit" id="DeletefromDB" value="Delete from DB" />';
    echo "<table width='auto' cellpadding='1px' cellspacing='0px' border=1 align='center'>
            <tr>
            <th align='center'><input id=checkall name=checkall type=checkbox value='' /></th>
            <th align='center'>Remedy Ticket No.</th>
            <th align='center'>Phone/Incident No.</th>
            <th align='center'>Category 2</th>
            <th align='center'>Category 3</th>
            <th align='center'>Status</th>
            <th align='center'>Create Date</th>
            <th align='center'>Severity</th>
            <th align='center'>Ban Type</th>
            <th align='center'>Resolved Date</th>
            </tr>"; 

    while($info = mysql_fetch_array($myData)) { 
        echo"<tr>"; 
            echo "<td align='center'>" . "<input type='checkbox' name='checkbox[]' value='add the id here which needs to be deleted'/></td>";
            echo  "<td align='center'>" . $info['ars_no'] . "<input type=hidden name=ars_no value=" . $info['ars_no'] . " </td>";
            echo  "<td align='center'>" . $info['phone_number'] . "<input type=hidden name=phone_number value=" . $info['phone_number'] . " size='11' maxlength='11' /> </td>"; 
            echo  "<td align='center'>" . $info['category_1'] . "<input type=hidden name=category_1 value=" . $info['category_1'] . "' /> </td>"; 
            echo  "<td align='center'>" . $info['category_2'] . "<input type=hidden name=category_2 value=" . $info['category_2'] . "' /> </td>";
            echo  "<td align='center'>" . $info['status'] . "<input type=hidden name=status value=" . $info['status'] . "' /> </td>"; 
            echo  "<td align='center'>" . $info['create_date'] . "<input type=hidden name=create_date value=" . $info['create_date'] . "' /> </td>";
            echo  "<td align='center'>" . $info['trouble_type_priority'] . "<input type=hidden name=trouble_type_priority value=" . $info['trouble_type_priority'] . " size='1' maxlength='1' /> </td>"; 
            echo  "<td align='center'>" . $info['ban_type'] . "<input type=hidden name=ban_type value=" . $info['ban_type'] . " size='1' maxlength='1' /> </td>";
            echo  "<td align='center'>" . "<input type=text name=resolved_date value=" . $info['resolved_date'] . " size='8' maxlength='8' /> </td>";
        echo "</tr>"; 
    } 

    echo "</table>";

echo "</form>";

现在，您可以在 resultgenerator.php 文件中查看：

if ($_POST['action'] == 'DeleteFromDB') {
    $ids_to_be_deleted = isset($_POST['checkbox']) ? $_POST['checkbox'] : array();
    //$ids_to_be_deleted will contain all the checked id's from the other page. You can get all those values in the array. Handle the remaining operation for delete here.
}

NEW UPDATE：

因此，如果您使用jQuery提交表单，那么最好将表单提交绑定更改为按钮上的单击功能。您可以将表单更改为：

  <link href="jquery-ui-1.10.2.custom/css/dark-hive/jquery-ui-1.10.2.custom.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="jquery-1.9.1.min.js" ></script>

<link rel="stylesheet" href="style.css" />
<script type="text/javascript" src="SMP1_deletefromDB.js"></script>
<script type="text/javascript">
    $(document).ready(function(){
        $("#RetrieveList").on('click',function() {
            var xid = $('#XiD').val();
            var date = $('#Date').val();
            $.post('resultgenerator.php',{xid:xid, date:date}, function(data){
            $("#results").html(data);
            });
            return false;
        });

        $("#DeletefromDB").on('click',function() {
            //get xid for delete like you do above. create a page delete.php or something and make an ajax call to some page to delete data
            return false;
        });
    });

这里我所做的是更改表单提交上的绑定事件，并在输入类型按钮的单击事件上绑定。我将类型提交更改为按钮。

现在，您可以检查每个按钮的单击事件并处理操作。

<强>更新

假设您在结果div中有检索到的列表。当用户选中复选框并单击删除按钮时，您可以使用以下脚本处理它：

$("#DeletefromDB").on('click',function() {
     //get all the checked values from checkboxes
     var ids = $('input[name=checkbox]:checked').map(function () {
         return this.value;
     }).get(); 

     if (ids.length === 0) 
         return false; //show some error message

     //post to delete.php file. In delete.php you can get the id's in $_POST['id'] as multidimensional array. You can handle the delete operation based on that
     $.post('delete.php',{id : ids}, function(data){
         //handle the message based on success or error
     });

      return false;
});

更新：

这可以是 delete.php 文件

$ids = isset($_POST['id']) ? $_POST['id'] : '';

if (!empty($ids)) {
   //implode the id's separated by commaas
   $ids_to_be_deleted = implode(',', $ids);

   $query = "DELETE FROM your_table WHERE field_to_be_checked IN ($ids_to_be_deleted)";
   //now run your query using mysql_query

}

NB：：自PHP 5.5.0起，不推荐使用mysql *函数，将来会删除它们。相反，应使用MySQLi或PDO_MySQL扩展程序

希望这可以帮助你：）

Answer 3

您可以使用下拉列表，您可以选择是否要检索或删除：

<select name='choseaction'>
<option value="RetrieveList">Retrieve List</option>
<option value="DeletefromDB">Delete from DB</option>
</select>

然后使用单个提交按钮。

<INPUT TYPE ="Submit" Name ="Submit" VALUE ="Submit">

之后你可以这样验证：

  if ($_POST['choseaction']=='RetrieveList')
   {
   ...
   } else if ($_POST['choseaction']=='DeletefromDB')
     {
     ...
     }

希望这有帮助！美好的一天。

需要通过复选框删除选定的行，只需一个删除按钮
