I created laravel project with the reactjs framework and I'm new for this framework. I have problem and why It happens every time i submit the form.
Goal: users can register through online
Problem:
Code:
constructor() {
super();
this.state = {
f_name:'',
l_name:'',
m_name:'',
email:'',
home_num:'',
contact_num:'',
Job_name:[],
employ_status:'',
employ_relocate:'',
employ_start_date:'',
employ_file:''
}
this.handleSubmit = this.handleSubmit.bind(this);
this.handle_fname = this.handle_fname.bind(this);
this.handle_lname = this.handle_lname.bind(this);
this.handle_mname = this.handle_mname.bind(this);
this.handle_email = this.handle_email.bind(this);
this.handle_homenum = this.handle_homenum.bind(this);
this.handle_contactnum = this.handle_contactnum.bind(this);
this.handle_employ_status = this.handle_employ_status.bind(this);
this.handle_employ_relocate = this.handle_employ_relocate.bind(this);
this.handle_employ_start_date = this.handle_employ_start_date.bind(this);
this.handle_employ_file = this.handle_employ_file.bind(this);
}
componentDidMount() {
const id = this.props.match.params.id;
axios.get('/api/online_application_job_title/' +id).then(response => {
this.setState({
Job_name:response.data
})
})
}
handleSubmit(e)
{
const data = {
firstname: this.state.f_name,
lastname : this.state.l_name,
middlename : this.state.m_name,
email : this.state.email,
home_number : this.state.home_num,
contact_num : this.state.contact_num,
job : this.state.Job_name[0].position_name,
employ_status : this.state.employ_status,
employ_relocate : this.state.employ_relocate,
employ_start_date : this.state.employ_start_date,
employ_file : this.state.employ_file
}
axios.post('/api/save_application',data).then(response => {
console.log(response);
}).catch(error => console.log(error));
}
handle_fname(e)

}
handle_employ_file(e){
this.setState({

}

Controller:
public function save_application(Request $request)
{
$firstname = $request->get('firstname');
$lastname = $request->get('lastname');
$middlename = $request->get('middlename');
$email = $request->get('email');

$employ_file = $request->get('employ_file');
$now = new DateTime();
DB::insert('INSERT INTO onlineapplication
(position_name,firstname,middlename,lastname,email,homenumber,phonenumber,employmentstatus,relocate,starting_date,destination,file_img_name,Status)
VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?)',[
$firstname,
$lastname,
$middlename,
$email,
$home_number,
$contact_num,
$job,
$employ_status,
$employ_relocate,
$employ_start_date,
$employ_file
]);
return response()->json('Successfully inserted');
}
When form tag is used, the submit will trigger the default behaviour that is based on the method provided and the action url. as in your example you are handling the data explicitly you should prevent the default behaviour. add the below code in handle submit
handleSubmit(e) {
e.preventDefault();
...
...
}
this will prevent the default behaviour.
Improvement for state update: you don't need individual functions to update the input value to state this can be combined in one function. to combine, provide the input name same as state name.
this.state ={
"f_name": '',
"l_name": '',
...
}
<input name="f_name" ... onChange={this.handleInputChange}/>
<input name="l_name" .. onChange={this.handleInputChange}/>
handleInputChange(e){
let target = e.target;
let name = target.name;
let value = target.value
this.setState({[name]: value})
}

First, I just want to introduce to you to the arrow function in JavaScript (ES6). Declaring private methods like this:
handle_fname = (e) =>
{
this.setState({
f_name:e.target.value,
})
}
will save you time from unnecessary binding in the constructor.
Regarding your question, you missed to show the content of your this.handleSubmit()
. Without this, I can assume that the form submit fired a get
call since you failed to put method
attribute in your <form/>
tag, and without indicating your method attribute will result to default get method. Get method when used, data submitted will be visible in the page address field of your browser.
EDIT
You already added your handleSubmit()
in your question, and it looks okay. If data is still shown in the address field of your browser, try adding method="post"
in your form tag like this:
<form onSubmit={this.handleSubmit} method="post">
