仅能回显我的可用搜索标签的第一行

Question

我正在尝试使用jQuery autocomplete来创建搜索栏，并且将我的行回显到availableTags中。但是我只从数据库中获得第一行。我知道我应该使用while循环，但不确定将其放置在何处。我已经尝试了多次，但我无法同时做到。

<?php 
  require_once 'config.php';
  require_once 'session.php';
  ini_set('display_errors', 1);
  ini_set('display_startup_errors', 1);
  error_reporting(E_ALL);

  $query = "SELECT `user_id`, `username`, `leeftijd`, `email` FROM `users` ";
  $resultaat = mysqli_query($mysqli, $query);
  $row = mysqli_fetch_array($resultaat);    
  var_dump($row);                      
?>

          "<?php echo $row['username'];?>",
          "<?php echo $row['leeftijd'];?>",

        $("#tags").autocomplete({
          source: availableTags
        });
      });
    <?php } ?>
  </script>

  <div class="ui-widget">
    <label for="tags">Tags: </label>
    <input id="tags">
  </div>
</body>
</html>

Answer 1

像这样添加while循环：

while($row =mysqli_fetch_array($resultaat))
{  
  var_dump($row); 
}

在javascript中，您可以像这样使用：

var availableTags = [
  <?php while($row =mysqli_fetch_array($resultaat)){?>
    "<?php echo $row['user_id'];?>",
    "<?php echo $row['username'];?>",
    "<?php echo $row['leeftijd'];?>",
 <?php } ?>
          "BASIC",
          "C",
          "C++",
          "Clojure",
          "COBOL",
          "ColdFusion",
          "Erlang",
          "Fortran",
          "Groovy",
          "Haskell",
          "Java",
          "JavaScript",
          "Lisp",
          "Perl",
          "PHP",
          "Python",
          "Ruby",
          "Scala",
          "Scheme"
        ];

现在可以正常工作了，谢谢大家。

<?php

require_once 'config.php';
require_once 'session.php';
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

$query = "SELECT `user_id`, `username`, `leeftijd`, `email` FROM `users` ";
                    $resultaat = mysqli_query($mysqli, $query);
                     $row = mysqli_fetch_array($resultaat);    
                      var_dump($row);
                      echo mysqli_num_rows($resultaat);
