Question

我的想法是填写HTML表单中的条目，然后将信息保存到数据库（phpmyadmin）。然后在谷歌地图上显示信息（导出）。

但由于语法和逻辑问题，它无法正常工作。

我的HTML表单：

<html>
<head></head>
<body>
    <form method="POST" action="../BackEnd/ShopSetup.php" name="Setup">
    <td>Name</td>
    <td>
        <input type="text" name="name"></td>
    </tr>
     <tr>
         <td>type</td>
         <td>
             <input type="varchar" name="type"></td>
     </tr>
    <tr>
        <td>Address</td>
        <td>
            <input type="text" name="address"></td>
    </tr>
    <tr>
        <td>Email</td>
        <td>
            <input type="email" name="email"></td>
    </tr>
    <tr>
        <td>Phone Number</td>
        <td>
            <input type="varchar" name="phone"></td>
    </tr>
    <tr>
        <td>longitude</td>
        <td>
            <input type="float" name="long"></td>
    </tr>
    <tr>
        <td>latitude</td>
        <td>
            <input type="float" name="lat"></td>
    </tr>
    <tr>
        <td>Opening Hour</td>
        <td>
            <input type="varchar" name="opening"></td>
    </tr>
    <tr>
        <td>Closing Hour</td>
        <td>
            <input type="varchar" name="closing"></td>
    </tr>
    <tr>
        <td>
            <input id="button" type="submit" name="submit" value="Setup"></td>

    </tr>
    <tr></tr>
    </form>
</body>
</html>

我的PHP页面在BackEnd上：

ShopSetup.php

     <?php


     include ("../Connections/Connection.php");



     if (isset($_POST["submit"]))
  {
      $name = $_POST["name"];   
      $type = $_POST["type"];
      $address = $_POST["address"];
      $email = $_POST["email"];
      $phone = $_POST["phone"];
      $long = $_POST["long"];
      $lat = $_POST["lat"];
      $opening = $_POST["opening"];
      $closing = $_POST["closing"];

  $sql = "INSERT INTO locations (name, type, address, email, phone, long, lat, opening, closing)
          VALUES('$name', '$type', '$address', '$email', '$phone', '$long', '$lat', '$opening', '$closing')";

  $query = mysql_query($sql);

  if (!$query)
  {
      die ("Error : " .  mysql_error());
  }
  if(empty($name) || empty($type) || empty($address) || empty($email) || empty($phone) || empty($long) || empty($lat) || empty($opening) || empty($closing))
      {
      echo "You did not fill out the required fields.";
      die();  // Note this
      }
  echo "<center></center>";
  }

  ?>
         <h1> Your order is complete!</h1>
                <p class="intro-text">You will see your shop on the map soon<br></p>
                <center> 

  <h3> <a href="../index.php"> go to home page  </a></h3>
  </center>

但是当我提交表格时，我得到了：

错误：您的SQL语法出错;查看与您的MySQL服务器版本对应的手册，以获得正确的语法，以便在“长，拉，开，关”附近使用VALUES（＆＃39;＆＃39;，＆＃39;＆＃39;，＆＃39;＆＃39;，＆＃39;＆＃39;，＆＃39;＆＃39;，＆＃39;＆＃39;，＆＃39;＆＃39;，＆＃39;＆＃ 39;，＆＃39;＆＃39;）＆＃39;在第1行

保存开始/结束时间的最佳HTML属性是什么：周，天。小时，分钟，秒？

您应该在列名周围使用反引号（`）。像这样：

JLabel Resultat = new JLabel("Résultat : ", SwingConstants.CENTER);

建议使用反引号用于表名和列名，但在使用import javax.swing.*; import java.awt.*; import java.awt.event.*; public class Exercice4 extends JFrame { private JTextField ZoneTxt, ZoneTxt2; private JPanel CalculPanel; private JLabel Resultat; private JComboBox Op; private JButton BCalcul; private int cbselect = 0; private double res; final String[] operateur = { "+", "-", "*", "/" }; public Exercice4() { super("Exercice 4"); JFrame FrameExercice4 = new JFrame(); JPanel CalculPanel = new JPanel(); ZoneTxt = new JTextField(10); ZoneTxt2 = new JTextField(10); final JComboBox Op = new JComboBox(operateur); BCalcul = new JButton("Calculer"); BCalcul.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { int cbselect = Op.getSelectedIndex(); if (cbselect == 0) { res = (((Double.parseDouble(ZoneTxt.getText()))) + ((Double .parseDouble(ZoneTxt2.getText())))); System.out.println(res); Resultat.setText("Résultat : " + String.valueOf(res)); } if (cbselect == 1) { // System.out.println(res1 - res2); } if (cbselect == 2) { // System.out.println(res1 * res2); } if (cbselect == 3) { // System.out.println(res1 / res2); } } }); JLabel Resultat = new JLabel("Résultat : ", SwingConstants.CENTER); FrameExercice4.setVisible(true); FrameExercice4.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); FrameExercice4.setSize(500, 500); FrameExercice4.add(CalculPanel); CalculPanel.add(ZoneTxt); CalculPanel.add(Op); CalculPanel.add(ZoneTxt2); CalculPanel.add(BCalcul); CalculPanel.add(Resultat, BorderLayout.CENTER); } public static void main(String[] args) { JFrame frame = new Exercice4(); } }等保留关键字时必须使用反对。

关于第二个问题，请查看HTML5 $sql = "INSERT INTO locations (`name`, `type`, `address`, `email`, `phone`, `long`, `lat`, `opening`, `closing`) VALUES('$name', '$type', '$address', '$email', '$phone', '$long', '$lat', '$opening', '$closing')";输入类型。请注意it is not supported by all browsers
