                    <input type="checkbox" name="interests" value="interests">Arts/Museum

Answer 1

如果使用方括号编写输入名称，则可以访问数组中的选定值：

<input type="checkbox" name="interests[]" value="Nature/Wildlife">Nature/Wildlife
<input type="checkbox" name="interests[]" value="Arts/Museum">Arts/Museum
<input type="checkbox" name="interests[]" value="Neighbourhoods">Neighbourhoods

如果您现在使用POST提交此表单，则在加载的页面上$_POST['interests']包含所选值

Answer 2

这将是我的复选框的示例html代码：

＆＃13;

    <form action="interests.php" method="post">
        <title>INTERESTS</title>
    <input type="checkbox" name="interests[]" value="Nature/Wildlife" />Nature/Wildlife<br />
    <input type="checkbox" name="interests[]" value="Arts/Museum" />Arts/Museum<br />

    <input type="submit" name="formSubmit" value="Submit" />
      </form>

＆＃13;

这将是我的兴趣.php代码：

  <?php
  $topics = $_POST['interests'];
  if(empty($topics)) 
  {
    echo("You didn't select anything");
  } 
  else
  {
    $N = count($topics);

    echo("You selected $N topic(s): ");
    for($i=0; $i < $N; $i++)
    {
      echo($topics[$i] . " ");
    }
  }
?>

如何在复选框中显示用户输入？
