我们以Demo模块为例，新建App/Demo/Models/Content.php

<?php namespace Phpcmf\Model\Demo;

// 模块内容模型类

class Content extends \Phpcmf\Model\Content {

    // 格式化内容搜索的param参数名称值
    public function _format_search_param_value($myfield, $param) {

        $hangyeb = $param['hangyeb'];
        unset($param['hangyeb']);

        $lmxzb = $param['lmxzb'];
        unset($param['lmxzb']);

        $ztqy = $param['ztqy'];
        unset($param['ztqy']);

        if ($ztqy) {
            $param['ztqy'] = $ztqy;
        }
        if ($lmxzb) {
            $param['lmxzb'] = $lmxzb;
        }
        if ($hangyeb) {
            $param['hangyeb'] = $hangyeb;
        }

        return [$myfield, $param];
    }
}
