Multiple searching using req.params node.js

Question

I am fairly new to Node.js and I want to execute multiple searches. I try to use req.params to get the search values from the textbox, but my code is not working. I tried to console the req.params.city , but nothing is displayed. I am using MySQL database.

Please see my code below:

Index.js

  router.get('/searche/:city/:date',function(req,res){
  let q = [req.params.city];
  console.log(q)
  db.query('SELECT  city_name, state_name, party_name, price, image, 
address, full_name  FROM register natural join party where userid = id and city_name LIKE "%'+req.params.city+'%" ' ,function(err, rows, fields) {
  if (err) throw err;
  res.render('test', {party: rows});
  });
 });

form.ejs

  <form action="/searche"  autocomplete="off">
        <input id="city" type="text" name="city" placeholder='Try "Minneapolis"'>
        <input placeholder="Choose Date" class="textbox-n" name = "date" type="text" onfocus="(this.type='date')" onblur="(this.type='text')" id="date">
        <button type="submit" class="searchButton"> <i class="fa fa search"></i></button>
   </form>

Answer 1

You're probably confusing params and body .

params is for PATH parameters used to parametrize the request path, say in your example, /searche/london/08-25-2019

Form data usually goes as body unless, ofcourse, you modify it somehow. So you can do:

router.get('/searche',function(req,res) {
  // req.body.city gets you city input
  ...
}

Note: You would have to mount body-parser or express 's inbuilt like express.json()

Answer 2

single quote in on wrong place, change this :

"%'+req.params.city+'%" ' 

to

`"...'%"+ req.params.city+ "%'"`

result :

db.query("SELECT  city_name, state_name, party_name, price, image, address, full_name  FROM register natural join party where userid = id and city_name LIKE '%"+ req.params.city+ "%'",()=> ...)
