表格PHP中每一行的Delete按鈕

Question

<td style="text-align: left;">
    <?php
          echo '<button type="button" class="btn btn-danger delete delete-account"><i class="fa fa-trash-o fa-lg"></i> Delete</a></button> 
                <input type="hidden" value="'. $r['user_id'] .'" name="delete[]">';
    ?>
</td>

我用這段JavaScript編寫了這段代碼：

$('button.delete-account').click(function(e) {
    swal({
        title: "Are you sure?",
        text: " <?php echo $r['user_id'] ?> You will not be able to undo this acction !",
        type: "warning",
        showCancelButton: true,
        confirmButtonColor: "#DD6B55",
        confirmButtonText: "Yes, delete it!",
        closeOnConfirm: false,
        html: false
    }, function() {
        swal("Deleted!", "Your imaginary file has been deleted.", "success");
    });
});

$ r ['user_id'] --->這基本上是一個函數，可以幫助我從數據庫中拉出所有用戶，對於此示例，它將拉出所有user_id。

問題是我每一行都有不同的用戶，當我單擊刪除按鈕時，我得到的是同一個user_id而不是單個ID。

我怎樣才能分別給每個用戶打電話？？？

多謝你們 ：）

Answer 1

更新：無法完全理解您的代碼，但是通過看這個小提琴就可以理解我的想法： 示例

使用創建的按鈕的值設置用戶ID是一種方法。 這樣，您將為每個創建的按鈕分配一個值，該值代表用戶的ID。

<td style="text-align: left;">
    <?php
          echo '<button type="button" value="'. $r['user_id'] .'" class="btn btn-danger delete delete-account"><i class="fa fa-trash-o fa-lg"></i> Delete</a></button>';
    ?>
</td>

然后在您的jquery中，使用jquery的$（this）獲取被單擊的按鈕的值，並通過調用.val（）來獲取被單擊的按鈕的值。 這樣，您為所有創建的按鈕只有一個處理程序。 ：

$('button.delete-account').click(function(e) {
swal({

title: "Are you sure?",
text: $(this).val()+" You will not be able to undo this acction !",
type: "warning",
showCancelButton: true,
confirmButtonColor: "#DD6B55",
confirmButtonText: "Yes, delete it!",
closeOnConfirm: false,
html: false
}, function(){
swal("Deleted!",
"Your imaginary file has been deleted.",
"success");
});
});

代碼未經測試 ...我無法完全驗證代碼的工作方式，因此我只復制了代碼並使用按鈕的值進行了微小的更改。.但是最重要的是讓您有了存儲的想法每個按鈕上用戶的值（id），並在處理中使用$（this）檢索它。

這兩個腳本可以。

show.php

<?php
/* 

Deletes a specific entry from the  table
*/

// connect to the database
include('connect-db.php');

// check if the 'id' variable is set in URL, and check that it is valid
if (isset($_GET['id']) && is_numeric($_GET['id']))
{
// get id value
$id = $_GET['id'];

// delete the entry
$result = mysql_query("DELETE FROM *fillin* WHERE id=$id")
or die(mysql_error()); 

// redirect back to the view page
 header("Location: urlocation.php");
 }
else
 // if id isn't set, or isn't valid, redirect back to view page
 {
header("Location: urlocation.php");
}

?>

delete.php

    <?php
    */  Displays all data from ' table


    // connect to the database
    include('dbconnectfile.php');

    // get results from database
    $result = mysql_query("SELECT * FROM dbase") 
            or die(mysql_error());  

      // display data in table
  echo "<p><b>info</b></p>";

    echo "<table border='2' border-color='#800000' cellpadding='10'>";
    echo "<tr> <th>fill-in</th> <th>fill-in</th><th>fill-in</th><th>Delete</th></tr>";

    // loop through results of database query, displaying them in the table
    while($row = mysql_fetch_array( $result )) {

            // echo out the contents of each row into a table
            echo "<tr>";
            echo '<td>' . $row['rowname'] . '</td>';
            echo '<td>' . $row['rowname'] . '</td>';
            echo '<td>' . $row['rowname'] . '</td>';

            echo '<td><a HREF="delete.php?id=' . $row['id'] . '"><img style="width: 25px; height: 25px; " alt="" src="">Delete</a></td>';
            echo "</tr>"; 
    } 

    // close table>
    ?>

Answer 3

您也可以從輸入中獲取ID（假設您正在使用jquery）

var id = $(e).parent().find('input[type="hidden"]').val();

Answer 4

在html上：

<td style="text-align: left;">
        <?php
              echo '<button type="button" class="btn btn-danger delete delete-account"><i class="fa fa-trash-o fa-lg"></i> Delete</a></button> 
                    <input type="hidden" class="userId" value="'. $r['user_id'] .'" name="delete[]">';
        ?>
    </td>

在js上：

$('button.delete-account').click(function(e) {
   var id = $(this).siblings('input.userId').val();
  swal({
   title: "Are you sure?",
   text: id + " You will not be able to undo this acction !",
   type: "warning",
   showCancelButton: true,
   confirmButtonColor: "#DD6B55",
   confirmButtonText: "Yes, delete it!",
   closeOnConfirm: false,
   html: false
  }, function(){ 
   $.post( "delete.php", { userID: id } );
   swal("Deleted!",
     "Your imaginary file has been deleted.",
     "success");  
  });
});

在delete.php上：

<?php
if(isset($_POST['userID'])){
  $id = $_POST['userID'];
  include('connect-db.php');
  mysql_query("DELETE FROM table_name WHERE userID = " . $id);
}
?>
