Question

我有学校命令。我需要在他们制作的应用程序上创建删除功能。我目前不知道该如何做。我知道如何在laravel中制作CRUD系统，但这是纯PHP。

ip_list = [{'1403': [-56, -58], 'data': '1'},
           {'1403': [-56, -58], 'data': '0'}]

for ip in ip_list:
    if ip.get('data') == '1':
        ip['mac'] = 'xyz'
print(ip_list)
#[{'1403': [-56, -58], 'data': '1', 'mac': 'xyz'}, {'1403': [-56, -58], 'data': '0'}]

在上面，您可以看到它们执行的private function add() { $klantId = -1; if (isset($_POST['inputklanten'])) { $klantId = $_POST['inputklanten']; } $row = $this->getKlantVars($klantId); $rowreservering = $this->getReserveringVars(-1); $row = array_merge($row, $rowreservering); $output = " <form action='?action=add' method='post' enctype='multipart/form-data'> <label>Selecteer klant </label> <select id='inputklanten' name='inputklanten'>" . $this->getKlanten() . " </select> <input type='submit' name='submit_klantselecteren' id='submit_klantselecteren' value='Selecteer klant'/> </form>" . $this->showReserveringForm($row); return $output; } protected function edit() { $reserveringId = -1; if (isset($_GET['reservering'])) { $reserveringId = $_GET['reservering']; } $row = $this->getReserveringVars($reserveringId); $klantId = $row['klant_id']; $rowklant = $this->getKlantVars($klantId); $row = array_merge($row, $rowklant); $output = $this->showReserveringForm($row); return $output; }和edit函数。我希望有人可以帮助我解决这个问题。

目前，这是我的删除功能。当我点击网址中ID为ID的删除按钮时，它会起作用并显示回显

add

Answer 1

    protected function delete()
{
    $reserveringId = -1;
    if (isset($_GET['reservering']))
    {
        $reserveringId = $_GET['reservering'];
    }

    // sql to delete a record
    $sql = ("DELETE FROM `reservering` WHERE `reservering`.`reservering_id` = '$reserveringId';");

    if ($this->connection->query($sql)) {
        $output = "Reservering is succesvol verwijderd";
        return $output;
    } else {
        $output = "Het is niet gelukt om de reservering te verwijderen";
        return $output;
    }
}

我做到了，感谢您的帮助：）

示例功能，但您必须学习。

function delete_products($id) {
    global $db;


    $sql = "DELETE FROM products ";
    $sql .= "WHERE id='" . db_escape($db, $id) . "' ";
    $sql .= "LIMIT 1";
    $result = mysqli_query($db, $sql);

    // For DELETE statements, $result is true/false
    if($result) {
      return true;
    } else {
      // DELETE failed
      echo mysqli_error($db);
      db_disconnect($db);
      exit;
    }
  }

OO

  public function delete() {
    $sql = "DELETE FROM " . static::$table_name . " ";
    $sql .= "WHERE id='" . self::$database->escape_string($this->id) . "' ";
    $sql .= "LIMIT 1";
    $result = self::$database->query($sql);
    return $result;
