在 php 中显示信息时需要帮助答案

【问题标题】：Needing help in displaying information in php在 php 中显示信息时需要帮助
【发布时间】：2016-08-01 14:02:27
【问题描述】：

我正在做一个附带项目，过去几天我取得了一些不错的进展，但我遇到了一个问题。我正在使用 php、mysql 和 bootstrap。副项目正在处理电影收藏。我得到的大部分信息都显示了我想要的方式，但类型。我可以在 mysql 端使用 groupconcat 显示所有类型，但我希望它们成为链接，以便用户可以单击它们并打开一个包含该类型所有电影的页面。如果我不使用 groupconcat，我只会显示一种类型。

这是在数据库中设置表的方式。

电影具有情节、时长、类型、类别等所有基本信息。主键是一个代码列。 Genres 是另一个包含所有流派信息的表。它也有一个代码pk。然后有一个链接它们的 MovieGenres 表。

电影 |代码 | PK|

类型 |代码|PK| |类型| |全流派名称

任何帮助将不胜感激！

这是我的网站部分代码

<?php 
    require '../database.php';
    $Code = null;
    if ( !empty($_GET['Code'])) {
        $Code = $_REQUEST['Code'];
    }

    if ( null==$Code ) {
        header("Location: index.php");
    } else {
        $pdo = Database::connect();
        $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        $sql = "
          SELECT 
            Movies.Code, Title, Plot, Movies.Type, 
            Movies.Category, Image, Score, Rated, Alt, Status, 
            YearReleased, Duration, 
            SUBSTRING(Duration, 1, CHAR_LENGTH(Duration) - 3) AS Duration2, 
            TotalEps, Types.code as tcode, Types.Type as ttype,

          AND Movies.Code=MovieGenres.MovieCode 
          AND MovieGenres.GenreCode=Genres.Code 
          AND Movies.Code = ?";
        $q = $pdo->prepare($sql);
        $q->execute(array($Code));
        $data = $q->fetch(PDO::FETCH_ASSOC);
        Database::disconnect();
    }
?>

【解决方案1】：

您的数据库设计看起来没有问题：

Movies { Code(PK), ... }
Genres { Code(PK), Genre, Full_Genre_Name }
MovieGenres { MovieCode, GenreCode }

但是，您的 SQL 选择了所有内容，并且它包含多行相同的电影数据。您可能需要一个 SQL 来选择一部电影，另一个 SQL 来获取其所有类型：

1) SELECT * FROM Movies WHERE Code = ?

2) SELECT g.* 
FROM Geners AS g 
JOIN MovieGenres AS mg ON g.Code = mg.GenreCode
WHERE mg.MovieCode = ?

取决于你的实际页面情况，如果你的页面上已经有流派的选择选项，你可以重复使用它，2）SQL更改为：

SELECT GenreCode from MovieGenres WHERE MovieCode = ?

<?php
// change to your db functions
$movieGenres = $db->getAll($sql2); 
// show clickable genres links: eg
echo '<h3>Genres:</h3><p>';
foreach ($movieGenres as $g) {
    echo '<a href="/genre/', $g['Code'] ,'">', $g['Genre_Full_Name'] ,'</a>; ';
}
echo '</p>';
?>

感谢您的回复。想了想，不知道怎么用php实现
现在我在一个标签部分有情节，在另一个标签部分有细节，我想把流派放在细节部分。
如果这个答案对原始问题是正确的，你应该接受它，如果你有其他问题，请发布一个新问题
