public function eBL() {
    $link_ebl = $this->config->address."?view=editprofile";
    $user_id = $this->data["id"];
    $name = $this->data["login"];
    if ($name == "") return $this->returnMessage("EMPTY_FIELD", $link_ebl);
    $result = $this->article->setName($user_id, $name);
    if ($result) return $this->returnPageMessage("SUCCESS_LOGIN", $this->config->address."?view=message");
    else return $this->unknownError($link_ebl);
}

public function setName($user_id, $name){
    return $this->setFieldOnID("user_id", "name", $name);
}

如果要更改列名，则应使用alter table（假设要更改名称的列为INT）

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>

    <!-- To change the popup menu and app text color  -->
    <item name="android:textColor">@color/colorPrimary</item>

    <!-- To change the background of options menu-->
    <item name="android:itemBackground">@color/skyBlue</item>
</style>
