如果数据库中存在数据，则应显示“编辑”按钮，否则应在ajax成功功能中显示“添加”按钮，而不显示页面重新加载

Question

如果数据库中存在数据，则应显示“编辑”按钮，否则应显示“添加”按钮，而不在ajax成功功能中显示页面重新加载。

在我的表单中，第一个面板工作正常，代码与我在第二个面板中执行的代码相同，但它不起作用。

形式

<form action="" id="data_form" method="post" > 
    <div class="dashboard-column-main"> 
    <div class="dashboard-container">

控制器中修改代码

 public function supplier_company_insert_update() {

        $this->db->select('*');
        $this->db->from('supplier_otherdetails');
        $this->db->where('supplierid_fk', $this->session->id);
        $query = $this->db->get();
        $save_type = $this->input->post('save_type');
        $company_name = $this->input->post('company_name');

        $save_typee = $this->input->post('save_typee');
        $cdate = $this->input->post('company_estd_date');

 if ($query->num_rows() > 0) {
            $this->Profile_model->update_supplier_company();
            //redirect('welcome/suppliercompany'); 
        } else {
            $this->Profile_model->insert_supplier_company();
            //redirect('welcome/suppliercompany'); 
        }

        if (trim($company_name) != '')
            $return_name = array('replace_text' => 'Edit', 'btn_text' => 'Update', 'save_type' => $save_type);
        else
            $return_name = array('replace_text' => 'Add', 'btn_text' => 'Save', 'save_type' => $save_type);


        if (trim($cdate) != '')
            $return_cdate = array('replace_textt' => 'Edit', 'btn_textt' => 'Update', 'save_typee' => $save_typee);
        else
            $return_cdate = array('replace_textt' => 'Add', 'btn_textt' => 'Save', 'save_typee' => $save_typee);
        echo json_encode(array_merge($return_name, $return_cdate));
}
