How can we store the value of a Modal in Pycord (2.x) in a method/function and then return it?

class title_input_modal(Modal):
    def __init__(self):
        super().__init__("Audio Title Input")

        self.add_item(InputText(label = "Audio Title", style = discord.InputTextStyle.short))

    async def callback(self, interaction: discord.Interaction):
        
        val = self.children[0].value
        await interaction.response.send_message(val)

How can I make a method and store the value of the response? If I try accessing title_input_modal.children[0] from another cog’s class method, this error pops up:-

Ignoring exception in view <View timeout=180.0 children=1> for item <Button style=<ButtonStyle.primary: 1> url=None disabled=False label='Play' emoji=<PartialEmoji animated=False name='▶️' id=None> row=None>:

    await item.callback(interaction)
  File "d:Programmingpythonintellijintellij_pythonAxC-777-Musicno_upload.py", line 137, in play_button_callback
    print(title_input_modal.children[0].value)

Answer

You can store the value in your class as a property and access it once the modal has been dismissed. To do so you will have to modify your class like this.

class title_input_modal(Modal):
    def __init__(self):
        super().__init__("Audio Title Input")
        
        #
        self.val = None

        self.add_item(InputText(label = "Audio Title", style = discord.InputTextStyle.short))

    async def callback(self, interaction: discord.Interaction):
        
        self.val = self.children[0].value
        await interaction.response.send_message(val)
        self.stop()

Then from where you call your modal, you will have to initialise it like this so that you can then access its properties

title_modal = title_input_modal()
await ...send_modal(title_modal)
await title_modal.wait()
print(title_modal.val)

Without the stop and wait methods, your bot won’t wait for the modal interaction to be over, so you won’t be able to access the value from the user.
