Incorporating optional fields into the form builder without being mandatory

For my current project on Ionic 4, I have implemented a form builder to create and validate forms. I have also included the [disabled] attribute in the form to disable it if all fields are not valid.

However, I noticed that even if I do not add Validators.required to a field, it still considers it as a required field. Here is an example of my code:

.ts file

    createAddAtelierDressForm() {
        this.addAtelierDressForm = this.fb.group({
            title: ['', Validators.required],
            description: ['', Validators.required],
            type: ['', Validators.required],
            size: ['', Validators.required],
            category: ['', Validators.required],
            city: ['', Validators.required],
            action: ['', Validators.required],
            price: ['', Validators.required],
            discount: ['', Validators.required],
            image_1: ['', Validators.required],
            image_2: [''],
            image_3: [''],
        });
    }

In the above code snippet, you can see that image_2 and image_3 do not have the required validation condition.

HTML

            <form [formGroup]="addAtelierDressForm">
                <!-- Input fields for different form elements -->
                <!-- Submit button with disabled attribute based on form validity -->

                <ion-button expand="full" type="submit" [disabled]="!addAtelierDressForm.valid">Add Dress</ion-button>
            </form>

The issue I am facing is that the form remains disabled even after filling all fields, including image_2 and image_3.

Answer №1

Although reactive forms work well with basic inputs, using validators with file inputs can be tricky.

To address this issue, one approach is to utilize a hidden input field that includes your validator (Using reactive form validation with <input type="file"> for an Angular app)

Alternatively, you can handle it by using the (change) event: https://medium.com/@amcdnl/file-uploads-with-angular-reactive-forms-960fd0b34cb5
