Question

我正在使用Select2的Multiple Select框。表单提交后，我通过wordpress在数据库中保存值。问题是如何在从数据库获取后在表单字段中显示所选值。代码如下：

from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import Column, Integer
from sqlalchemy.orm import relationship
Base = declarative_base()

class Plane(Base):
    __tablename__ = 'Plane'
    plane_id = Column(Integer, primary_key=True)

class Car(Base):
    __tablename__ = 'Car'
    car_id = Column(Integer, primary_key=True)

Answer 1

您可以尝试在价值属性

之后添加“已选择”

<select name="jws_ob_pages_show_name[]" class="spages" multiple="multiple">';

$pages = get_pages(array(
    'sort_order' => 'asc',
    'sort_column' => 'post_title',
    'parent' => -1,
    'post_type' => 'page',
    'post_status' => 'publish'
));
foreach($pages as $page){
    $returner .= '<option value="'.$page->post_title.'" selected>'.$page->post_title.'</option>';
}

$returner .= '</select>';

表单提交后显示选定的值选择2使用php
