Why is my Angular Reactive form not retrieving the value from a hidden field?

I've encountered a problem where the hidden field in my form is not capturing the product id unless I manually type or change its value. It consistently shows as "none" when submitting the form.

TS https://i.stack.imgur.com/W9aIm.png

HTML https://i.stack.imgur.com/xGY0V.png

Console https://i.stack.imgur.com/1R0M0.png

I'm looking for suggestions on how to ensure that the hidden field captures the correct value without manual intervention. Any best practices or tips would be greatly appreciated!

Answer №1

assign the value during initialization process.

_id: FormControl(this.products._id)

Answer №2

Utilize the getRawValue() function to retrieve all values from a form regardless of their disabled status. The value property is recommended for obtaining values from a group as it does not include disabled controls in the FormGroup.

   this.updateProductForm.patchValue({
      _id: updatedProduct._id }   
    );

   updateProductForm.getRawValue() 

Answer №3

Although it may be past the deadline to respond to the question, I encountered a similar issue with hidden fields while using a reactive form approach. Hopefully, my solution can benefit someone else in need. You can utilize [ngModel] to assign a value to hidden fields, like so -

<input type="hidden" formControlName="type" [ngModel]="products._id">
