不在 bootstrap 缩略图中生成数据

Question

我想在 bootstrap 缩略图中显示一些数据。我不明白为什么它不显示从数据库中获取的任何数据。数据库连接正确。

<div class="jumbotron">
 <div class="container">
  <center>
  <h1> Welkom!</h1>
   <p>Op de website van Ter Bruggen Antiek en Curiosa.<br />Voor uw mooiste antieke kroonluchters, lampen, meubelen en overige producten.</p>
   <p><a class="btn btn-primary btn-lg disabled" href="?page=info" role="button">Meer weten?</a></p>
  </center>
 </div>
</div>
<div class="container">
 <center>
  <h2>Uitgelicht!</h2>
 </center>
  <div class="row">
   <?php
    $sql = "SELECT * FROM advertentie, categorie WHERE advertentie.categorie_id = categorie.categorie_id AND uitgelicht=1";
    $result = $connect->query($sql);
    
    if ($result->num_rows > 0){
     while ($row = $result -> fetch_assoc()){
      echo   "<div class='col-lg-3'>";
      echo     "<div class='thumbnail'";
      echo     "<img class='img-square img-responsive' src='../img/uploads/".$row['filename']."'/> ";
      echo      "<div class='caption'>";
      echo    "<h4>".$row['advertentietitel']."</h4>";
      echo    "<p>".$row['categorie_naam']."</p>";
      echo    "<p>".$row['verkooprijs']."</p>";
      echo    "<p><a href='?page=details&id=".$row['advertentie_id']." class='btn btn-primary'>Bekijk</a></p>";
      echo   "</div>";
      echo   "</div>";
      echo   "</div>";
     }
    }
   ?>
  </div> 
</div>

Answer 1

您的select查询不正确。您应该使用 mysql 的 JOIN。我不知道你的数据库结构。如果你显示你的数据库结构，那么我可以帮助你。请尝试以下查询并分享结果

$sql = "SELECT advertentie.* FROM advertentie LEFT OUTER JOIN categorie on  advertentie.categorie_id = categorie.categorie_id WHERE advertentie.uitgelicht=1";
