我是这个的新手，我不知道为什么“详情”选项卡上没有显示任何内容，但我确实成功地将数据插入到数据库中。有人可以帮我这个吗？

<?php
require ("Data/TaxiData.php");

    closedir($handle);


    $imageArray = array();

    $plate = $_POST["txtCar Plate Number"];
    $price = $_POST["txtPrice"];
    $detail = $_POST["txtDetail"];


    $itaxi = new TaxiEntity(-1, $name, $gender, $faculty, $type, $plate, $price);

function GetitaxiTypes() {
  $TaxiData = new TaxiData();
    return $TaxiData->GetitaxiTypes();

}
?>

所以，这是TaxiData.php。也许这里出了问题。

    <?php

require（“Entities / TaxiEntity.php”）;

类TaxiData {

    require ('mysql_connect.php');

    mysql_connect($db_host, $db_username, $db_pass) or die(mysql_error());
    mysql_select_db($db_name);
    $result = mysql_query("SELECT DISTINCT type FROM itaxi") or die(mysql_error());
    $types = array();


    while ($row = mysql_fetch_array($result)) {
        array_push($types, $row[0]);
    }


    mysql_close();
    return $types;
}


function GetitaxiByType($type) {
    require ('mysql_connect.php');

    mysql_connect($db_host, $db_username, $db_pass) or die(mysql_error());
     mysql_select_db($db_name);

    $query = "SELECT * FROM itaxi WHERE type LIKE '$type'";
    $result = mysql_query($query) or die(mysql_error());
    $TaxiArray = array();


    while ($row = mysql_fetch_array($result)) {
        $id = $row[0];
        $name = $row[1];
        $gender = $row[2];
        $faculty = $row[3];
        $type = $row[4];
        $plate = $row[5];

更新： 这是数据库 database

答案 0 :(得分：1)

看起来你错过了一些代码

function Insertitaxi() {
    $name = $_POST["txtName"];
    $gender = $_POST["txtGender"];
    $faculty = $_POST["txtFaculty"];
    $type = $_POST["txtCar Type"];
    $plate = $_POST["txtCar Plate Number"];
    $price = $_POST["txtPrice"];
    $detail = $_POST["txtDetail"];


    $itaxi = new TaxiEntity(-1, $name, $gender, $faculty, $type, $plate, $price);
    $TaxiData = new TaxiData();
    $TaxiData->Insertitaxi($itaxi);
}

这条线  $itaxi = new TaxiEntity(-1, $name, $gender, $faculty, $type, $plate, $price); 看起来应该是这样  $itaxi = new TaxiEntity(-1, $name, $gender, $faculty, $type, $plate, $price, $detail);

通过它的外观错过了最后的字段$ detail。试一试。

更新 - 还可以尝试将缺失的印版固定在其他功能上 - 

function Updateitaxi($id, TaxiEntity $itaxi) {
    $query = sprintf("UPDATE itaxi
                        SET name = '%s', gender = '%s', faculty = '%s', type = '%s',
                        price = '%s', detail = '%s'
                      WHERE id = $id",
           mysql_real_escape_string($itaxi->name),
            mysql_real_escape_string($itaxi->gender),
            mysql_real_escape_string($itaxi->faculty),
            mysql_real_escape_string($itaxi->type),
            mysql_real_escape_string($itaxi->plate),
            mysql_real_escape_string($itaxi->price),
             mysql_real_escape_string($itaxi->detail));

    $this->PerformQuery($query);
}

将更新更改为包括plate =％s 

"UPDATE itaxi SET name = '%s', gender = '%s', faculty = '%s', type = '%s', plate = '%s', price = '%s', detail = '%s' WHERE id = $id",
