我想要默认选中一个复选框，

Question

我什么时候会更新我的学期，默认情况下会选中一个复选框，这怎么可能？

<select name="semester">

  <option value="1">Semester 1</option>
  <option value="2">Semester 2</option>
  <option value="3">Semester 3</option>
</select>

请尝试这个

<select name="semester">
            <option value="">Select Semester</option>
            <option value="1" <?php if($data['semester']==1){echo 'selected';}?>>Semester 1</option>
            <option value="2" <?php if($data['semester']==2){echo 'selected';}?>>Semester 2</option>
            <option value="3" <?php if($data['semester']==3){echo 'selected';}?>>Semester 3</option>
</select>
