How to play "up" and "down" animation when moving diagonally?

Initially, when I move diagonally my sprite only looks to the side but I want it to look up and down when I move diagonally. I tried adding this code under the left and right movement animation.

if Input.is_action_pressed("up_key"):
				anim.play("back_walk")
			elif Input.is_action_pressed("down_key"):
				anim.play("front_walk")

It now looks up and down but the animation doesn’t play. How can I properly do this?

Script:

extends CharacterBody2D

@export var speed = 130
var current_dir = "none"
func get_input():
	var input_direction = Input.get_vector("left_key", "right_key", "up_key", "down_key")
	velocity = input_direction * speed

func _physics_process(delta):
	get_input()
	move_and_slide()

	var anim = $AnimatedSprite2D
	
	if Input.is_action_pressed("left_key"):
		current_dir = "left"
		play_anim(1)
	elif Input.is_action_pressed("right_key"):
		current_dir = "right"
		play_anim(1)
	elif Input.is_action_pressed("up_key"):
		current_dir = "up"
		play_anim(1)
	elif Input.is_action_pressed("down_key"):
		current_dir = "down"
		play_anim(1)
	else:
		play_anim(0)
	

func play_anim(movement):
	var dir = current_dir
	var anim = $AnimatedSprite2D
	
	if dir == "left":
		anim.flip_h = true
		if movement == 1:
			anim.play("side_walk")
			if Input.is_action_pressed("up_key"):
				anim.play("back_walk")
			elif Input.is_action_pressed("down_key"):
				anim.play("front_walk")
		elif movement == 0:
			anim.play("side_idle")
	if dir == "right":
		anim.flip_h = false
		if movement == 1:
			anim.play("side_walk")
			if Input.is_action_pressed("up_key"):
				anim.play("back_walk")
			elif Input.is_action_pressed("down_key"):
				anim.play("front_walk")
		elif movement == 0:
			anim.play("side_idle")
	if dir == "up":
		if movement == 1:
			anim.play("back_walk")
		elif movement == 0:
			anim.play("back_idle")
	if dir == "down":
		if movement == 1:
			anim.play("front_walk")
		elif movement == 0:
			anim.play("front_idle")

When you move diagonally you press two buttons, lets say left_key and up_key to move to the top left.
Now, in your _physics_process you first check if left_key is pressed. Since both left_key and up_key are pressed, this is true and you play the “left” animation. Because you are using else-ifs you don’t check any other key press anymore.

What you need to do, is to give ‘up and down’ precedence by changing the order in which you check which button is pressed.
