How do I ask for a number to be entered when I enter a character other than a number in input?

Hi @florent. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
In your code, you are using the
register
function from react-hook-form
to register the input field. The valueAsNumber: true
option is used to ensure that the value entered is treated as a number. However, this does not prevent a user from entering non-numeric characters.
To prevent non-numeric characters from being entered, you can add an onChange
event handler to the OutlinedInput
component that checks if the entered value is a number. If it's not, it can display an error message or prevent the character from being entered.
Unfortunately, the knowledge sources provided do not contain a specific example of this. You may need to refer to the documentation or other resources for react-hook-form
and Chakra UI's OutlinedInput
component to implement this feature.
Here is a general idea of how you might implement this:
In the onChange
handler, isNaN(value)
will return true
if the value is not a number. You can replace the comment // handle non-numeric input
with code to handle this case as you see fit.

{...register('available_points', {
required: t('errors.required.field', {
field: 'available_points',
}),
How do I write that required phrase in locales?
Let me check the knowledge base for you. One moment! :books:
----------------------
To define the required phrase in your locales, you need to add it to your translation file. The translation file is a JSON file that contains key-value pairs for different phrases in your application.
Here is an example of how you can define the required phrase in your
locales/en/common.json
file:
In this example, {{field}}
is a placeholder that will be replaced with the actual field name when the translation function t
is called.
So, when you use t('errors.required.field', { field: 'available_points' })
, it will look for the key errors.required.field
in the translation file and replace {{field}}
with 'available_points'
, resulting in the string "The available_points is required".
Please note that the structure of your translation file and the keys you use may vary based on your application's requirements and the structure you have defined for your translations.
For more information, you can refer to the Refine documentation on internationalization (i18n) (https://refine.dev/docs/guides-concepts/i18n#adding-the-translations-files).

How do I create an input that only accepts numbers?
React Text Field component - Material UI
Text Fields let users enter and edit text.
Let me check the knowledge base for you. One moment! :books:
----------------------
To create an input field that only accepts numbers in Material-UI, you can use the
TextField
component with the type
prop set to "number"
. Here is a basic example:
This will render an input field that only accepts numeric input. However, please note that this does not prevent the user from typing non-numeric characters into the field. It only changes the behavior of the input field to be more suitable for numeric input (for example, by showing a numeric keyboard on mobile devices).
If you want to prevent non-numeric characters from being entered entirely, you would need to add an onChange
event handler that checks the entered value and prevents non-numeric characters from being entered. However, this is not covered in the provided knowledge sources.
For more information, you can refer to the Material-UI TextField documentation (https://mui.com/material-ui/react-text-field/).
