Widget To String (WidgetToString) - ComfyUI-KJNodes

The Widget To String node locates target nodes through three primary methods: by using the node's unique ID, via a user-defined node title, or by connecting an input to the any_input socket (used when neither ID nor title is provided).

The Widget To String node is a tool for extracting widget values from other nodes within a workflow. It captures the current value of a specific widget on a designated node and converts it into a STRING format for output, facilitating its use in other nodes that require text input.

Node Functionality

This node locates target nodes through three primary methods: by using the node's unique ID, via a user-defined node title, or by using the any_input connection as a fallback when neither ID nor title is given. It supports extracting values from a single widget or multiple widgets (specified by a comma-separated list) on the target node, and can handle various data types such as INT, FLOAT, and BOOLEAN. Its internal mechanism parses the workflow metadata to find the corresponding node based on the provided location information, then reads the value of the specified widget(s), and finally formats it into a string according to the settings (e.g., number of decimal places for FLOAT values).

Connection Inputs (Inputs)

Parameter Name	Data Type	Required	Default Value	Range/Options	Description
`any_input`	IO	No	-	-	An optional connection that identifies the target node when neither `id` nor `node_title` is set. It also ensures the target node exists in the workflow. Typically connected to the node from which you wish to read values.

Control Parameters (Parameters)

Parameter Name	Data Type	Required	Default Value	Range/Options	Description
`id`	INT	Yes	0	0 - 100000 (Step: 1)	Specifies the unique numeric ID of the target node for precise node lookup. Leave at 0 to use the `any_input` connection or `node_title` if set. The valid range is 0 to 100000, with a step of 1.
`widget_name`	STRING	Yes	-	-	Specifies the name(s) of the widget(s) to read from the target node. Can be a single widget name or a comma-separated list of multiple widget names.
`return_all`	BOOLEAN	Yes	False	-	Controls the output behavior when `widget_name` specifies multiple widgets. When False, outputs the first valid value. When True, concatenates all values into a single string for output.
`node_title`	STRING	No	-	-	Locates the target node using a user-defined node title. This is only effective if the node title has been manually modified.
`allowed_float_decimals`	INT	No	2	0 - 10	Number of decimal places to display for FLOAT values.

Output

Parameter Name	Data Type	Description
STRING	STRING	The string output after converting the read widget value(s).

Usage Scenarios

In an image generation workflow, you can use this node to read the value of the "seed" widget from a KSampler node and pass it as part of a filename to a Save Image node. Alternatively, you can use it to capture the weight settings from a group of LoRA nodes and concatenate them into a descriptive prompt text.

Notes

Please note that when using the node ID for location, you need to enable "Node ID Badge Mode" in the main ComfyUI settings to display the IDs. The node title method only works if the user has manually edited the node title; otherwise, the node cannot be found using this method.
If you leave both id at 0 and node_title empty, you must connect an input to any_input to specify the target node.

The Widget To String node is from the ComfyUI-KJNodes node package.
