Is there something I'm overlooking? The utilization of FormData and .get from FormGroup seems intriguing

I've encountered some challenges while working on a contact form using Angular Reactive Forms and HttpClient for post requests. There seems to be an issue with the FormData append part, as I'm receiving an error message stating "Object is possibly 'null'" for the three formData.appends I've used.

Has anyone encountered a similar problem or have any insights on how to resolve this issue?

Here is the component code:

import { Component, OnInit } from '@angular/core';
import { FormGroup, FormBuilder, FormControl, Validators } from '@angular/forms';
import { HttpClient } from '@angular/common/http';
import { MessageService } from 'primeng/api';

@Component({
  selector: 'app-contact',
  templateUrl: './contact.component.html',
  styleUrls: ['./contact.component.scss']
})
export class ContactComponent implements OnInit {

  // Component code here

}

Below is the HTML code for the component:

<section id="contact">
    <div class="main">
        <!-- HTML code for contact form goes here -->
    </div>
</section>

And here's the App Module:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
// Other imports and declarations go here

@NgModule({
  // App Module contents go here

})
export class AppModule {
}

Answer №1

After receiving some guidance from another source, I was able to resolve the issue. It turns out that my initial mistake was forgetting to import Reactive Forms, as I had only imported Forms.

I encountered some challenges with formData.append, but after finding a more efficient coding solution, everything started working smoothly. Additionally, I faced a problem where I couldn't utilize response["result"], but I managed to fix it using (response: any) =>.

Although I'm not sure if I made an error in the form section, everything is functioning properly now after incorporating some code snippets from StackBlitz.

Answer №2

Is there a reason for the use of "FormData"? A basic object can be sent easily instead, for instance:

  this.http.post('...',
      {
        name: this.contactForm.value.name,
        email: this.contactForm.value.email,
        message: this.contactForm.value.message,
      }
    )
