Question

我目前正在使用PHP脚本将记录添加到我的数据库中，这在一些调试后正常工作。当脚本运行时，它会打开一个带有查询输出的新页面。

我想在页面顶部的导航栏下，在执行查询的同一页面上显示查询输出。

以下是我当前的页面。

这是期望的结果。

HTML页面的相关代码：

  <form name="registration" action="addKlant.php" target="_blank" method="post">
    <h3><i class="fa fa-plus-circle"></i> Klant toevoegen</h3>
    <div class="form-input">
      <label><i class="fa fa-info-circle"></i> Naam</label>
      <input type="text" name="klantNaam">
    </div>
    <div class="form-input">
      <label><i class="fa fa-info-circle"></i> Soort klant</label>
      <select class="" name="klantSoort">
        <option value="">Bedrijf</option>
        <option value="">Particulier</option>
      </select>
    </div>
    <div class="form-input">
      <label><i class="fa fa-info-circle"></i> Telefoonnummer</label>
      <input type="number" name="klantTel">
    </div>
    <div class="form-input">
      <label><i class="fa fa-info-circle"></i> E-mail adres</label>
      <input type="email" name="klantEmail">
    </div>
    <div class="form-input">
      <label><i class="fa fa-info-circle"></i> Straat & huisnr</label>
      <input type="text" name="klantAdres">
    </div>
    <div class="form-input">
      <label><i class="fa fa-info-circle"></i> Postcode</label>
      <input type="text" name="klantPostcode">
    </div>
    <div class="form-input">
      <label><i class="fa fa-info-circle"></i> Plaats</label>
      <input type="text" name="klantPlaats">
    </div>
    <div class="form-input">
      <input type="submit" name="submit" value="Klant toevoegen">
    </div>
  </form>

addKlant.php

<?php
require('db.php');

$stmt = $con->prepare('INSERT INTO `klanten` (klant_naam, klant_soort, klant_telefoon, klant_email, klant_straat, klant_postcode, klant_plaats) VALUES (?, ?, ?, ?, ?, ?, ?)');

if($stmt) {
  $klant_naam = $_POST['klantNaam'];
  $klant_soort = $_POST['klantSoort'];
  $klant_telefoon = $_POST['klantTel'];
  $klant_email = $_POST['klantEmail'];
  $klant_adres = $_POST['klantAdres'];
  $klant_postcode = $_POST['klantPostcode'];
  $klant_plaats = $_POST['klantPlaats'];

  $stmt->bind_param('ssissss', $klant_naam, $klant_soort, $klant_telefoon, $klant_email, $klant_adres, $klant_postcode, $klant_plaats);

  $stmt->execute();

  $con->close();

  echo "Klant is toegevoegd, je kan deze pagina nu sluiten.";
}

?>

我在考虑使用像if($_POST)这样的东西？但我不知道如何完全实现它。

如果页面刷新以添加输出并不重要，但是我想将它保存到PHP而不使用JS（当然，如果只有PHP可以使用）。

非常感谢任何提示。

Answer 2

我假设HTML表单不是addKlant.php的一部分？在这种情况下，一旦处理完表单，您可能希望重定向到包含HTML表单的页面，并使用某种变量传递查询字符串中的项目以显示查询已运行。

即

// ... after your form processing
$con->close();
header("Location: htmlpage.php?queryresult=ok");
exit;

然后在HTML表单页面中：

<?php if ($_GET['queryresult'] == 'ok') print "query ran okay"; ?>

我不知道查询的结果可能是什么样的 - 如果它在一个url中可编码，你可以传递整个响应，即

header("Location: htmlpage.php?queryresult=" . urlencode( $queryresultstring ));

在同一页面上显示查询结果PHP
