Question

我正在尝试从数据库中获取数据但是每当我尝试运行脚本时，表单的数据都会被解除。实际上这个表单将显示技术新闻。它应该是正确的对称但我无法使这个页面适当对称请帮助我。 HTML代码

<html>
        <head>
            <title> News</title>
            <link rel="stylesheet" href="stylesheet/style1.css" type="text/css" />
        </head>
        <body>
            <div id="outer">
                <div id='InnerPage'>
                <div class="clear"></div>
                <div id="ContentWrappertutorial">
                    <div id="firstSection">
                       <div id="TechNewsLeft">
                           <h1>News</h1>



          <?php
                            $q = "select * from technews order by time desc";
                            $run = mysqli_query($con, $q);

                            while ($fetch = mysqli_fetch_array($run)){
                        ?>
                        <div id="containerfortechnews">
                        <div class="part1_partition1">
                                <img src="newsImages/<?php echo $fetch[2]; ?>" width="320px" height="260px"/>
                            </div>                        
                        <div class="part2_partition1">
                                <div class="underpartition1">
                                    <h3><?php echo $fetch[1]; ?></h3>
                                </div>
                                <div class="underpartition2">

                                    <?php 
                                        $string = substr($fetch[3], 0, 100);
                                        echo "<p>".$string."...<a href='#'> know more</a></p>"; ?>
                                </div>
                        <?php } ?>
                    </div>
            </div>

Answer 1

如果页面呈现没有错误，那么此页面上的代码就可以了。也许错误在于查询

select * from technews order by time desc

如果time的数据类型为varchar，那么您不能指望正确的排序。这可能有效：

select * from technews order by cast(time as DATE) desc

此表单的动态数据未经确定
