通过单击按钮从表中删除自定义的行

此代码适用于我，但通过单击此按钮，没有任何更改。只有手动刷新我的页面后才能看到删除结果。有什么补充来解决这个问题？通过单击按钮从表中删除自定义的行

<?php 
foreach($results as $value){ 
    echo "<tr>"; 
    echo "<td class='posts column-posts'>".$value->id."</td>"; 
    echo "<td class='email column-email'>".$value->email."</td>"; 
    echo "<td class='description column-description'><div id='col-container'>".$value->details."</div></td>"; 
    $delRow = "delete_registration_{$value->id}"; 
    echo "<td class='posts column-posts'><input type='submit' name= $delRow value='delete'/></td>"; 
    echo "</tr>"; 
    if(isset($_POST[$delRow])){ 
     $wpdb->delete('conference_register', array('id' => $value->id)); 
    } 
}

你必须移动的结果集查询上面的'$ wpdb-> delete'声明，因为你得到的结果，显示它们，然后删除该行。 – fyrye

好吧，我会试试。 –

您需要跳过输出行，如果你删除它。类似这样的：

<?php 
foreach($results as $value){ 
    $delRow = "delete_registration_{$value->id}"; 
    if(isset($_POST[$delRow])){ 
     $wpdb->delete('conference_register', array('id' => $value->id)); 
    } else { 
     echo "<tr>"; 
     echo "<td class='posts column-posts'>".$value->id."</td>"; 
     echo "<td class='email column-email'>".$value->email."</td>"; 
     echo "<td class='description column-description'><div id='col-container'>".$value->details."</div></td>"; 
     echo "<td class='posts column-posts'><input type='submit' name= $delRow value='delete'/></td>"; 
     echo "</tr>"; 
    } 
}

如果您要删除该行，则可以避免显示该行。

foreach($results as $value){ 
    if(isset($_POST[$delRow])){ 
     $wpdb->delete('conference_register', array('id' => $value->id)); 
    } 
    else { 
     echo "<tr>"; 
     echo "<td class='posts column-posts'>".$value->id."</td>"; 
     echo "<td class='email column-email'>".$value->email."</td>"; 
     echo "<td class='description column-description'><div id='col-container'>".$value->details."</div></td>"; 
     $delRow = "delete_registration_{$value->id}"; 
     echo "<td class='posts column-posts'><input type='submit' name= $delRow value='delete'/></td>"; 
     echo "</tr>"; 
    } 
}
