Question

我的网络应用有问题，当我填写表单并验证时，我的phpmyadmin页面中没有任何内容！连接很好，但没有数据导出。

这是我的PHP代码：

  <?php
      $connect=mysqli_connect("localhost","root","","ramsa");

      if (mysqli_connect_errno()) {
        echo ("Échec de la connexion : %s\n" . mysqli_connect_error());
        exit();
    }


$db_selected = mysqli_select_db($connect,"ramsa");

if (!$db_selected)
  {
  die ("Can\'t use this databse : " . mysqli_error());
  }


$query = " INSERT INTO 'reservoir' (CodeReservoir, NomReservoir, AdresseReservoir, Latitude, Longtitude, Capacite, CodeRadial, Type, PseudoType, Alimentation)
           VALUES ('$_POST[coderes]', '$_POST[nomres]', '$_POST[adressres]', '$_POST[latitude]', '$_POST[longitude]', '$_POST[capaciteres]', '$_POST[coteradres]', '$_POST[typeres]','$_POST[pseutype]', '$_POST[alimentationres]')";

echo "Resvoir bien ajouté.";
mysqli_query($connect,$query);
mysqli_close($connect);



?>

这是我的表单的HTML代码：

    <form id="formulaire" role="form" action="send.php" method="POST">
                    <h3 style="color:red;">Ajouter un reservoir</h3>
                    <label for="coordlat" style="margin-bottom:7px;">Latitude du point</label>

首先，我要说你绝对不需要将$ _POST超级全局中的任何内容直接添加到类似的SQL查询中。您可以广泛接受SQL注入攻击。

话虽如此，您是否验证了列名和值类型？

我建议先在你的php中尝试这样的东西来识别错误

<?php
      $connect=mysqli_connect("localhost","root","","ramsa");

      if (mysqli_connect_errno()) {
        echo ("Échec de la connexion : %s\n" . mysqli_connect_error());
        exit();
    }


$db_selected = mysqli_select_db($connect,"ramsa");

if (!$db_selected)
  {
  die ("Can\'t use this databse : " . mysqli_error());
  }


$testData = Array(); //fill this with a false data set for each column of data

$testInput = "'".implode("','",$testData)."'";

$query = " INSERT INTO `reservoir` (`CodeReservoir`, `NomReservoir`, `AdresseReservoir`, `Latitude`, `Longtitude`, `Capacite`, `CodeRadial`, `Type`, `PseudoType`, `Alimentation`)
           VALUES ($testInput)";

echo $query."<br/>";  //so that you can run it directly in the server using PHPMyAdmin or MySQL Workbench or similar application
mysqli_query($connect,$query);
echo mysqli_error($connect);
mysqli_close($connect);
?>

显然，Insert因某些原因失败了。根据我的经验，这几乎总是由于字段名称不正确。如果没有看到您的字段列表，那么如果确实如此，则很难确定。无论如何，上面的调试代码应该可以帮助您确定错误的位置，以便您可以纠正错误。

编辑：注意到您将表名括在单引号中。这是无效的语法。您希望将它们包含在刻度`（或重音符号，即转义键下方的键）中。同时将所有字段名称括在刻度线中（我已经编辑了上面的代码示例以反映这些更改）。

将数据从表单导出到我的数据库（PHP / MySQL）
