<input name="callbackUrl" type= "hidden" id="callbackUrl">
<h2>${error}</h2>
<br/>
<button class="btn btn-lg btn-primary btn-block" type="submit">Log In</button>
<h4 class="text-center">Create an account</h4>
</form>
</body>
<script>
var url_string = window.location.href; //window.location.href
var url = new URL(url_string);
var c = url.searchParams.get("callbackUrl");
console.log(c);
document.getElementById("callbackUrl").value = c;
</script>
</html>
add #RequestParam("callbackUrl") String callBackUrl to the method in your controller.
Like so:
public String myMethod(#RequestParam("callbackUrl") String callBackUrl, …) {
System.out.println(callBackUrl); //this will print the url to console
}

I'm creating an Object in GET method and initialize it with nulls. Then I set some values and send it to the POST method, but after this process all of values that I set earlier are nulls. How could I repair it? I've tried to use hidden fields, but it didn't help.

I am new to Vue.js. I am trying to make a form dynamic (only a certain part of the form dynamic.). A user can have multiple guarantors. So I made the Guarantor form Dynamic with VueJS. When I submit the form and return the request, I see only the last array. Its always the last array, all others are lost.
This is the blade file.
<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="{{ asset('css/app.css')}}">
<title>Laravel</title>
</head>
<body>
<div id="app">
<div class="container pt-5">
<form action="{{ route('submit.store')}}" method="post">
#csrf
<div class="card-body">
<h4 class="card-title">User Detail</h4>
<input type="text" class="form-control mb-1" name="user_name" id="user_name" placeholder="Name" />
<input type="email" class="form-control mb-1" name="user_email" id="user_email"
placeholder="Email" />
<textarea name="about" class="form-control" id="about" cols="30" rows="10"
placeholder="About"></textarea>
</div>
<dynamic-form></dynamic-form>
</form>
</div>
</div>
<script src="{{ asset('js/app.js') }}"></script>
</body>
</html>
And this is how the VueComponent looks.
<template>
<div>
<button class="btn btn-success mb-3" #click.prevent="addNewUser">Add User</button>
<div class="card mb-3" v-for="(user, index) in users" :key="index">
<div class="card-body">
<span class="float-right" style="cursor:pointer" #click.prevent="removeForm(index)" >X</span>
<h4 class="card-title">Guarantor No: {{ index }}</h4>
<input type="text" class="form-control mb-1" name="name" id="name" placeholder="Name" v-model="user.name" />
<input type="email" class="form-control mb-1" name="email" id="email" placeholder="Email" v-model="user.email"/>
<textarea name="about" class="form-control" id="about" cols="30" rows="10" placeholder="About" v-model="user.about"></textarea>
</div>
</div>
<input type="submit" class="btn btn-primary" value="submit">
</div>
</template>
<script>
export default {
name: 'dynamic-form',
data() {
return{
users: [
{
name: '',
email: '',
about: ''
}
]
}
},
methods: {
addNewUser: function() {
this.users.push({
name: '',
email: '',
about: ''
});
},
removeForm: function(index) {
this.users.splice(index, 1);
}
}
}
</script>
How can I tackle this problem?
In PHP, values with the same name attribute value will get overwritten. (See the "How do I get all the results from a select multiple HTML tag?" section here).
You can create arrays of values by adding a bracket to the name. For example, if you made the name of the "name" input name[], name will be an array of names in PHP.
In your case, you could use this format: name="guarantors[][name]". That way you will get an array in PHP under the key guarantors (e.g. $request->guarantors) and each of the values in guarantors will be an array with the values name, email, etc.
here is my form
<!--destinationList List-->
<div class="form-group">
<div class="col-sm-3">
<label for="Destination">Destination</label>
</div>
<div class="col-sm-9">
<input type="text" class="form-control" th:field="*{destinationList[0]}" />
<input type="text" class="form-control" th:field="*{destinationList[1]}" />
<input type="text" class="form-control" th:field="*{destinationList[2]}" />
<input type="text" class="form-control" th:field="*{destinationList[3]}" />
</div>
</div>
<div class="form-group">
<div class="col-sm-9">
<button type="submit" class="btn btn-primary btn-block">Calculate</button>
</div>
</div>
</form>
And I'm going to fill following model
public class PriceSearchDTO {
private List<String> destinationList;
public List<String> getDestinationList() {
return destinationList;
}
public void setDestinationList(List<String> destinationList) {
this.destinationList = destinationList;
}
}
I can do this. But I hard coded number of input fields in the list as above in the view. I need to genarate them dynamically and make the number of element in the list is airbitary.
Try this:
<div class="col-sm-9">
<input type="text" class="form-control" th:each="destination : ${destinationList}" th:field="*{destination}" />
</div>
You are using Iteration in Thymeleaf. In fact, there is a quite complete set of objects that are considered iterable by a th:each attribute.
Like this :
<!DOCTYPE html SYSTEM "http://www.thymeleaf.org/dtd/xhtml1-strict-thymeleaf-4.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:th="http://www.thymeleaf.org">

<title>Good Thymes Virtual Grocery</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<link rel="stylesheet" type="text/css" media="all"
href="../../../css/gtvg.css" th:href="#{/css/gtvg.css}" />
</head>
<body>
<h1>Product list</h1>
<table>
<tr>
<th>NAME</th>
<th>PRICE</th>
<th>IN STOCK</th>
</tr>
<tr th:each="destination: ${destinations}">
<td th:text="${destination}">Onions</td>
</tr>
</table>
<p>
Return to home
</p>
</body>
</html>
And Controller in Spring framework.
#RequestMapping(value = "/")
public ModelAndView showView(ModelAndView mav) {
List<String> destinations = new ArrayList<String>();
destinations.add("elementA");
destinations.add("elementB");
destinations.add("elementC");
mav.addObject("destinations", destinations);
mav.setViewName("/viewName");
return mav;
}
I am trying to use jquery-validate plugin to validate a form inside a bootstrap-dialog. The "required" rule doesn't prevent me from submitting a form with an empty text field. However, "digits" rule works so that means validation is initialized properly. What am I missing here? Thanks.
Here's how I display the bootstrap-dialog and how I initialize validation.

You have a hard-coded value of "test" on the input so the required rule is already satisfied without the user having to enter anything.
BTW: I don't think you have a good naming system here: id="id", name="id", id="name", and name="name". It's not semantic, not scalable, and potentially confusing.
