Dynamic Text¶
Builds a text string by replacing placeholders with values from up to 10 optional inputs. Placeholders use the format {{input_1}} ... {{input_10}}, and all occurrences are globally replaced using simple string substitution.
Usage¶
Use this node to compose prompts, messages, or metadata strings that need to inject variable values at runtime. Enter a template in the text field and reference any of the optional inputs via {{input_n}}. Connect or set the optional inputs you need; fields progressively appear as you set previous ones.
Inputs¶
| Field | Required | Type | Description | Example |
|---|---|---|---|---|
| text | True | DYNAMIC_STRING | Template text that can reference variables using {{input_1}} to {{input_10}}. The editor supports quick selection of available variables. | User: {{input_1}} requested {{input_2}} items. |
| input_1 | False | STRING | Value to substitute for {{input_1}}. | Alice |
| input_2 | False | STRING | Value to substitute for {{input_2}}. This field becomes visible after input_1 is set. | 3 |
| input_3 | False | STRING | Value to substitute for {{input_3}}. Visible after input_2 is set. | priority |
| input_4 | False | STRING | Value to substitute for {{input_4}}. Visible after input_3 is set. | express |
| input_5 | False | STRING | Value to substitute for {{input_5}}. Visible after input_4 is set. | blue |
| input_6 | False | STRING | Value to substitute for {{input_6}}. Visible after input_5 is set. | medium |
| input_7 | False | STRING | Value to substitute for {{input_7}}. Visible after input_6 is set. | USD |
| input_8 | False | STRING | Value to substitute for {{input_8}}. Visible after input_7 is set. | 2025-01-01 |
| input_9 | False | STRING | Value to substitute for {{input_9}}. Visible after input_8 is set. | note |
| input_10 | False | STRING | Value to substitute for {{input_10}}. Visible after input_9 is set. | thanks |
Outputs¶
| Field | Type | Description | Example |
|---|---|---|---|
| text | STRING | The final compiled text after replacing all matching placeholders with provided input values. | User: Alice requested 3 items. |
Important Notes¶
- Placeholder format: Use double braces with exact key names, e.g., {{input_1}}. Keys are case-sensitive.
- Global replacement: All occurrences of a given placeholder are replaced throughout the text.
- Optional inputs: Only set the inputs you need. Unused placeholders remain unchanged.
- Progressive visibility: input_2 shows after input_1 is set; this pattern continues up to input_10.
- No expression parsing: Substitution is plain text replacement; it does not evaluate formulas or nested placeholders.
- Limit of 10 variables: Only input_1 through input_10 are supported.
Troubleshooting¶
- Variables not replacing: Confirm the placeholder uses double braces and exact key name (e.g., {{input_3}}) and that the corresponding input is not empty.
- Fields not visible: Set the previous input to reveal the next (e.g., set input_1 to show input_2).
- Unexpected leftover {{...}}: Provide values for the missing inputs or remove those placeholders from the template.
- Empty output: Ensure the required 'text' template is not empty; optional inputs default to empty strings if not set.
