将 SQL 数据库中的数据显示到 php/html 表中

【中文标题】将 SQL 数据库中的数据显示到 php/html 表中

【英文标题】：Display data from SQL database into php / html table

【发布时间】：2018-04-25 09:19:10

【问题描述】：

我一直在尝试模仿link 中的解决方案，但没有成功。我的目的是从 SQL 数据库中导入数据并将它们放入一个 html 表中，以便我可以使用 CSS 来修改表的外观。有人可以帮帮我吗？

谢谢。

代码

<?php

$mysqli = NEW mysqli('localhost','username','password','database');

require('/home/database/public_html/wp-load.php');
$id = get_the_ID();

$resultSet = $mysqli->query("SELECT * FROM sweepstake_data WHERE item_id = $id");

if($resultSet->num_rows !=0)

echo "<table>"; // start a table tag in the HTML

    while($rows = $resultSet->fetch_assoc())
    
        $description = $rows['description'];
        $links = $rows['links'];
        $category = $rows['category'];
        $eligibility = $rows['eligibility'];
        $start_date = $rows['start_date'];
        $end_date = $rows['end_date'];
        $entry_frequency = $rows['entry_frequency'];
        $prizes = $rows['prizes'];
        $victory_prizes = $rows['victory_prizes'];
        $additional_comments = $rows['additional_comments'];

        "<tr><td>" . echo $description != "" ? "<p>Name: $description<br />" : "" ;
        "<tr><td>" . echo $links != "" ? "Link: <a href=$links>Click here</a> <br />" : "" ;
        "<tr><td>" . echo $category != "" ? "Category: $category<br />" : "" ;
        "<tr><td>" . echo $eligibility != "" ? "Eligibility: $eligibility<br />" : "" ;
        "<tr><td>" . echo $start_date != "" ? "Start date:$start_date<br />" : "" ;
        "<tr><td>" . echo $end_date != "" ? "End date: $end_date<br />" : "" ;
        "<tr><td>" . echo $entry_frequency != "" ? "Entry frequency: $entry_frequency<br />" : "" ;
        "<tr><td>" . echo $prizes != "" ? "Prizes: $prizes<br />" : "" ;
        "<tr><td>" . echo $victory_prizes != "" ? "Victory prizes: $victory_prizes<br />" : "" ;
        "<tr><td>" . echo $additional_comments != "" ? "Additional comments: $additional_comments<br />" : "" ;

    

echo "</table>"; //Close the table in HTML

else 
    echo "No results.";


?>

【问题讨论】：

我首先建议您了解准备好的和绑定的查询

@Strawberry 肯定会看看。我当然会阅读更多内容，但快速搜索会发现 SQL 注入的危险？您是否暗示我的代码容易受到它的影响？谢谢。

【参考方案1】：

使用准备好的查询而不是正常的。

此代码将起作用：

<?php

$mysqli = NEW mysqli('localhost','username','password','database');

require('/home/database/public_html/wp-load.php');
$id = get_the_ID();

$resultSet = $mysqli->prepare("SELECT * FROM sweepstake_data WHERE item_id=?");
$resultSet->bind_param('i',$id);
$resultSet->execute();
$result = $resultSet->get_result();


if($result->num_rows !=0)

echo "<table>"; // start a table tag in the HTML

while($rows = $result->fetch_assoc())

    $description = $rows['description'];
    $links = $rows['links'];
    $category = $rows['category'];
    $eligibility = $rows['eligibility'];
    $start_date = $rows['start_date'];
    $end_date = $rows['end_date'];
    $entry_frequency = $rows['entry_frequency'];
    $prizes = $rows['prizes'];
    $victory_prizes = $rows['victory_prizes'];
    $additional_comments = $rows['additional_comments'];

    echo   "<tr><td>";
    $description != "" ? "<p>Name: $description<br />" : "" ;
     echo "<tr><td>";
    echo $links != "" ? "Link: <a href=$links>Click here</a> <br />" : "" ;
    echo "<tr><td>";
    echo $category != "" ? "Category: $category<br />" : "" ;
     echo "<tr><td>";
     echo $eligibility != "" ? "Eligibility: $eligibility<br />" : "" ;
    echo "<tr><td>" ;
     echo $start_date != "" ? "Start date:$start_date<br />" : "" ;
    echo "<tr><td>" ;
    echo $end_date != "" ? "End date: $end_date<br />" : "" ;
    echo "<tr><td>";
    echo $entry_frequency != "" ? "Entry frequency: $entry_frequency<br />" : "" ;
   echo  "<tr><td>";
   echo $prizes != "" ? "Prizes: $prizes<br />" : "" ;
    echo "<tr><td>";
    echo $victory_prizes != "" ? "Victory prizes: $victory_prizes<br />" : "" ;
    echo "<tr><td>";
    echo $additional_comments != "" ? "Additional comments: $additional_comments<br />" : "" ;



echo "</table>"; //Close the table in HTML

else 
echo "No results.";


?>

不幸的是，我无法让它工作。感谢您的帮助。

【参考方案2】：

使用下面的代码。您的问题是打印值

<?php

$mysqli = NEW mysqli('localhost','username','password','database');

require('/home/database/public_html/wp-load.php');
$id = get_the_ID();

$resultSet = $mysqli->query("SELECT * FROM sweepstake_data WHERE item_id = $id");

if($resultSet->num_rows !=0)

echo "<table>"; // start a table tag in the HTML

    while($rows = $resultSet->fetch_assoc())
    
        $description = $rows['description'];
        $links = $rows['links'];
        $category = $rows['category'];
        $eligibility = $rows['eligibility'];
        $start_date = $rows['start_date'];
        $end_date = $rows['end_date'];
        $entry_frequency = $rows['entry_frequency'];
        $prizes = $rows['prizes'];
        $victory_prizes = $rows['victory_prizes'];
        $additional_comments = $rows['additional_comments'];

        echo   "<tr><td>";
        $description != "" ? "<p>Name: $description<br />" : "" ;
         echo "<tr><td>";
        echo $links != "" ? "Link: <a href=$links>Click here</a> <br />" : "" ;
        echo "<tr><td>";
        echo $category != "" ? "Category: $category<br />" : "" ;
         echo "<tr><td>";
         echo $eligibility != "" ? "Eligibility: $eligibility<br />" : "" ;
        echo "<tr><td>" ;
         echo $start_date != "" ? "Start date:$start_date<br />" : "" ;
        echo "<tr><td>" ;
        echo $end_date != "" ? "End date: $end_date<br />" : "" ;
        echo "<tr><td>";
        echo $entry_frequency != "" ? "Entry frequency: $entry_frequency<br />" : "" ;
       echo  "<tr><td>";
       echo $prizes != "" ? "Prizes: $prizes<br />" : "" ;
        echo "<tr><td>";
        echo $victory_prizes != "" ? "Victory prizes: $victory_prizes<br />" : "" ;
        echo "<tr><td>";
        echo $additional_comments != "" ? "Additional comments: $additional_comments<br />" : "" ;

    

echo "</table>"; //Close the table in HTML

else 
    echo "No results.";
