Question

我正在尝试从数据库中提取记录并将其显示在我的php表单上，供用户更新。在我的数据库表中，有一个名为stage的列。在舞台下，有基础，中级和进步。这是一个例子：

因此，当我按下我的php表格（第2张图片）中的粉底按钮时，只会记录他们的舞台为基础的记录，将显示在列表中（连同他们的姓名，联系电话，电子邮件和学生证）有什么方法可以做到吗

Answer 1

你在找这样的东西吗？

<?php
  $stage = $_GET['stage'];
  $sql = 'SELECT * FROM {$tablename} WHERE stage=:stage';

  $db = new PDO('mysql:host=localhost;dbname=yourdbname', $user, $pass);
  try {
    $statement = $db->prepare($sql);
    $statement->execute(array(':stage', db->quote($stage)));
    foreach($statement->fetchAll() as $row) {
      // Do things here.
    }
  } catch (PDOException $e) {
    print "Error!: " . $e->getMessage() . "<br/>";
    die();
  }

<?php
    include('connect-db2.php');

    // get results from database
    $result = mysql_query("SELECT * FROM players2 WHERE stage = 'foundation'") 
            or die(mysql_error());  

    echo "<table border='1' cellpadding='10'>";
    echo "<tr> <th>S/N</th> <th>Student_ID</th> <th>Name</th> <th>Contacts No.</th> <th>Email</th><th>Stage</th></tr>";

    while($row = mysql_fetch_array( $result )) {
        // echo out the contents of each row into a table
        echo "<tr>";
        echo '<td>' . $row['id'] . '</td>';
        echo '<td>' . $row['student_id'] . '</td>';
        echo '<td>' . $row['name'] . '</td>';
        echo '<td>' . $row['contact_no'] . '</td>';
        echo '<td>' . $row['email'] . '</td>';
        echo '<td>' . $row['stage'] . '</td>';
        echo '<td><a href="edit2.php?id=' . $row['id'] . '">Edit</a></td>';
        echo '<td><a href="delete2.php?id=' . $row['id'] . '">Delete</a></td>';
        echo "</tr>";
    } 
?>

过滤数据库表中的记录以进行查看和更新
