如果我从dorpdown中选择本地销售并输入DEF,GHI值那么DEF,GHI的总和应该显示在总价值中,或者如果我从下拉列表中选择Inter State,Stock Transfers,那么如果我们输入ABC值那么该值应该是以总值显示,否则如果我们从下拉列表中选择JOB WORK,EXEMPTED SALES,则总值应显示为零。应该将我们获得的总值插入数据库中。
控制器:
function addinvoice()
{
$this->load->library('form_validation');
$this->form_validation->set_error_delimiters('<br /><span class="error"> ','</span>');
$this->form_validation->set_rules('user','User');
$this->form_validation->set_rules('freight_charges');
$this->form_validation->set_rules('abc');
$this->form_validation->set_rules('def');
$this->form_validation->set_rules('ghi');
$this->form_validation->set_rules('total');
if($this->form_validation->run()== FALSE)
{
$data['mainpage']='invoice';
$data['mode']='add';
$this->load->view('templates/template',$data);
}
else
{
$this -> invoice_model -> insert();
$this->flash->success('<h2> Details added Successfully!</h2>');
redirect('invoice');
}
}
型号:
function insert()
{
$data['total']=0;
$data['user'] = $this->input->post('user');
$data['ghi'] = ($this->input->post('ghi'))?$this->input->post('ghi'):0;
$data['abc'] = ($this->input->post('abc'))?$this->input->post('abc'):0;
$data['def'] = ($this->input->post('def'))?$this->input->post('def'):0;
$data['total'] = $data['ghi'] + $data['abc'] + $data['def'];
$data['freight_charges'] = $this->input->post('freight_charges');
$this->db->insert('invoice',$data);
}
查看:
<script>
function showRequiredOption(cval)
{
if((cval=='interstate') || (cval == "stocktransfers"))
{
$('#ghi').hide();
$('#def').hide();
$('#abc').show();

无论我从下拉列表中选择哪些值,只有那些要插入数据库的值,其余值应该在数据库中插入为零。
实际上我没有得到如何做到这些可以任何人检查这个。谢谢提前。
答案 0 :(得分:0)
你应该在php代码中检查发布的值为:
$total = 0;
if($this->input->post('this')){
$total = $this->input->post('this');//value in total
}
if($this->input->post('this2')){
$total += $this->input->post('this2');//value in total
}
并且最后在db中发送$ total值。 简而言之,如果是其他标签,你可以设置变量,如;
$this = ($this->input->post('this'))?$this->input->post('this'):0;
$this2 = ($this->input->post('this2'))?$this->input->post('this2'):0;
然后最后你可以将它们总计并保存到数据库中。或者如上面建议的那样,在您的表中将列设为DEFAULT 0。
-------在你的情况下------
function insert()
{
$data['total']=0;
$data['user'] = $this->input->post('user');
$data['ghi'] = ($this->input->post('ghi'))?$this->input->post('ghi'):0;
$data['abc'] = ($this->input->post('abc'))?$this->input->post('abc'):0;
$data['def'] = ($this->input->post('def'))?$this->input->post('def'):0;
$data['total'] = $data['ghi'] + $data['abc'] + $data['def'];
$data['freight_charges'] = $this->input->post('freight_charges');
$this->db->insert('invoice',$data);
}
---------------在JavaScript中------------ 在你的事件处理程序上,你可以通过他们的ID来总结这些。
var total = parseInt($('#ghi').val())+parseInt($('#def').val());
然后在您的总div中显示此总数
$('#yourTotalDiv').text(total);

在输入详细信息时显示总金额。
mongoose.connect("mongodb://localhost/blog-react");
app.set("view engine", "ejs");
app.use(express.static("public"));
app.use(bodyParser.json()); // <--- Here
app.use(bodyParser.urlencoded({extended: true}));
