通過單擊按鈕從表中刪除自定義的行

此代碼適用於我，但通過單擊此按鈕，沒有任何更改。只有手動刷新我的頁面後才能看到刪除結果。有什麼補充來解決這個問題？通過單擊按鈕從表中刪除自定義的行

<?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)); 
    } 
}

你必須移動的結果集查詢上面的'$ wpdb-> delete'聲明，因爲你得到的結果，顯示它們，然後刪除該行。 – fyrye

好吧，我會試試。 –

您需要跳過輸出行，如果你刪除它。類似這樣的：

<?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>"; 
    } 
}

如果您要刪除該行，則可以避免顯示該行。

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>"; 
    } 
}
