通过url中的特定字段从MySQL数据库表中获取数据

Im PHP新的MySQL。我正在开发一个歌本网站。通过url中的特定字段从MySQL数据库表中获取数据

我想在每个字母表的单独页面中按字母顺序创建表格。

当用户点击菜单中的字母就会直接到这个页面site/publicsearch.php?browse=a

这是数据库：

| ID | TITLE  | ARTIST | CATEGORY | ALPHABET | 
+----------------------------------------------------+ 
| 1 | Amazing love | XXXXXX | Love  |  a | 
| 2 | Above all  | XXXXXX | Worship |  a | 
| 3 | BXXXX   | XXXXXX | Love  |  b | 
| 4 | BXXXX   | XXXXXX | Worship |  b |

我拉上面的数据库表是这样的：它工作正常。

<?php 
$servername = "localhost"; 
$username = "xxxxxxx"; 
$password = "xxxxxxxx"; 
$db_name = "xxxxxxxxxxx"; 

// Create connection 
$conn = new mysqli($servername, $username, $password, $db_name); 

// Check connection 
if ($conn->connect_error) { 
    die("Connection failed: " . $conn->connect_error); 

echo "Connected successfully"; 
exit(); 
} 
    // Attempt select query execution 

    $sql = "SELECT * FROM lyrics_a"; 

    if($result = mysqli_query($conn, $sql)){ 

     if(mysqli_num_rows($result) > 0){ 

      echo "<table class='table'>"; 

       echo "<tr>"; 

        echo "<th>#</th>"; 

        echo "<th>Title</th>"; 

        echo "<th>artist</th>"; 

        echo "<th>cateogry</th>"; 

       echo "</tr>"; 

      while($row = mysqli_fetch_array($result)){ 

       echo "<tr>"; 

        echo "<td>" . $row['id'] . "</td>"; 

      echo "<td> <a href=publicsong.php?id=".$row['id'] . ">" . $row['eng_title'] . "</a> " . $row['tel_title'] . " </td>"; 

        echo "<td>" . $row['artist'] . "</td>"; 

        echo "<td>" . $row['category'] . "</td>"; 

       echo "</tr>"; 

      } 

      echo "</table>"; 

      // Close result set 

      mysqli_free_result($result); 

     } else{ 

      echo "No records matching your query were found."; 

     } 

    } else{ 

     echo "ERROR: Could not able to execute $sql. " . mysqli_error($link); 

    } 



    // Close connection 

    mysqli_close($link); 

    ?>

我需要单独的字母顺序表是这样的：

Alphabet "a" table results `site/publicsearch.php?browse=a` 

| ID | TITLE  | ARTIST | CATEGORY | ALPHABET | 
+----------------------------------------------------+ 
| 1 | Amazing love | XXXXXX | Love  |  a | 
| 2 | Above all  | XXXXXX | Worship |  a | 

Alphabet "b" table results `site/publicsearch.php?browse=b` 

| ID | TITLE  | ARTIST | CATEGORY | ALPHABET | 
+----------------------------------------------------+ 
| 3 | BXXXX   | XXXXXX | Love  |  b | 
| 4 | BXXXX   | XXXXXX | Worship |  b |

我尝试下面的代码无法正常工作。

<?php 
$servername = "localhost"; 
$username = "xxxxxx"; 
$password = "xxxxxxx"; 
$db_name = "xxxxxxxxx"; 

// Create connection 
$conn = new mysqli($servername, $username, $password, $db_name); 
// Check connection 
if ($conn->connect_error){ 
    die("Connection failed: " . $conn->connect_error); 
} 
$alphabet = $_GET['alphabet']; 
$id = mysqli_real_escape_string($conn,$id); 
$query = "SELECT * FROM `lyrics` WHERE `alphabet`='" . $alphabet . "'"; 
$result = mysqli_query($conn,$query); 

while($row = mysqli_fetch_array($result)) { 
echo "<br><br>"; 
echo $row['id']; 
echo $row['title']; 
echo $row['lyrics']; 
echo $row['alphabet']; 
} 
?>

我是新手。请帮忙。谢谢。

$alphabet = $_GET['alphabet']; 
$id = mysqli_real_escape_string($conn,$id); 
$query = "SELECT * FROM `lyrics` WHERE `alphabet`='" . $alphabet . "'";

替换为：

$alphabet = mysqli_real_escape_string($conn,$_GET['browse']); 
$query = "SELECT * FROM `lyrics` WHERE `alphabet`= '" . $alphabet . "' ";

谢谢。成功了！ – dan

您提出以下网址：publicsearch.php?browse=a

但在你的脚本，你正在使用的请求参数$_GET['alphabet']

此外，你并不需要在数据库中一个单独的列alphabet，您可以使用：

$letter = $_GET['browse']; 
$sql = "SELECT * FROM `lyrics` WHERE title LIKE '{$letter}%'"
