HTML Checkboxes in Form POST - html

Question

vI am working with HTML and have a form with a group of checkboxes:
-> What are your favorite colors?
---> Red
---> Green
---> Blue
Say I selected, Red AND Green. In the form post, I want it to look like: "favorite-color": ["red", "green"]. Now, it only shows one of the colors, even if I select multiple. Here is some sample code:
<div class="custom-control custom-checkbox">
<input type="checkbox" class="custom-control-input" id="red" name="color" value="red">
<label class="custom-control-label" for="red">Red</label>
</div>
<div class="custom-control custom-checkbox">
<input type="checkbox" class="custom-control-input" id="green" name="color" value="green">
<label class="custom-control-label" for="green">Green</label>
</div>
<div class="custom-control custom-checkbox">
<input type="checkbox" class="custom-control-input" id="blue" name="color" value="blue">
<label class="custom-control-label" for="blue">Blue</label>
</div>
My post, when I select red AND green:
{'color': 'green'}
By the way, I am using Django as my backend to parse the form POST.
Is there a way to do this? Thanks!

Answer 1

Via this blog:
For multiselects or inlines (one-to-many fields) that have multiple values, use .getlist():
So:
request.POST.getlist("color")

Answer 2

Give all the input type="checkbox" elements the same value for their name attribute and then the values from the checked checkboxes will be submitted as a single value for the one name. In most server-side environments, that means that if you request that form value, you'll get all the values with the single form field request.
