Answer 1

您必须将一个名为selected="selected"的属性添加到默认情况下要选择的<option>标记中。

Answer 2

Simply import the $gender value from the db into the edit page and then add this :

<select name="gender" id="gender">
    <option>Select One</option>
    <option <?if $gender=="Male" echo 'selected="selected"'?>>Male</option>
    <option <?if $gender=="Female" echo 'selected="selected"'?>>Female</option>
</select>
