Php 如何将表单中的数据正确插入数据库？

所以我一直在使用MVC方法开发一个表单，它将使用PDO将数据插入数据库。我有addWine表单、addWine控制器、数据访问模型和wine类模型。提交表单时，不会发生任何事情，也不会填充数据库。有人能指出我做错了什么吗

<form action= "" method="POST">
    <table>
     <b>Fill the form to add new wine</b><p><p>
    <tr>
    <td> Wine ID:     </td>
    <td><input type="text" name= "wineID"/></td>
    </tr>

    <tr>
    <td>Wine Country ID: </td>
    <td><input type="text" name="wineCountryID"/></td>
    </tr>

    <tr>
    <td>Wine Size ID: </td>
    <td><input type="text" name="wineSizeID"/></td>
    </tr>

    <tr>
    <td>Wine Rating ID: </td>
    <td><input type="text" name="wineRatingID"/></td>
    </tr>

    <tr>
    <td>Wine Colour ID: </td>
    <td><input type="text" name="wineColourID"/></td>
    </tr>
