解决方案

试试这个：

在您的表单中，插入多个复选框的方法

<form method="POST" action="test2.php">
        <input type="checkbox" name="chk[]" value="InputText1">InputText1<br>
        <input type="checkbox" name="chk[]" value="InputText2">InputText2<br>
        <input type="submit" name="sub1">
</form>


if(isset($_POST['sub1'])) // check the submitted form and print the values
   {
     echo "You selected the following checkbox:<br/>";
     foreach ($_POST['chk'] as $value) {
      echo $value."<br>";
    }
