# Is not empty

> Checks if the value is not null, not an empty string, and not an empty array.

export const FormField = ({property, label, required = false, diType, uiPatterns, children}) => {
  const patterns = Array.isArray(uiPatterns) ? uiPatterns : uiPatterns ? [uiPatterns] : [];

Checks whether the value coming in actually contains something. It is the opposite of [Is empty](/references/condition/empty): the condition is met for any value that is not null, not blank text (`""`), and not an empty list. Use this to act only when a field has been filled in, for example to skip products that are missing a name or orders that have no line items. This condition has no settings: it looks at whatever value it is given and reports whether that value has content.

One thing to watch: a value such as the text `"0"`, the number `0`, or a false on/off value all count as having content, so this condition treats them as not empty. Only null, blank text, and an empty list count as empty.

This documentation describes: [Schema](/schemas/condition/not-empty)

## Sample data

This checks each entity's `middleName` field. The condition has no settings of its own.

| Incoming value    | Result         |
| ----------------- | -------------- |
| `"Lee"` (text)    | Matches        |
| `"0"` (text)      | Matches        |
| `""` (blank text) | Does not match |
| null (no value)   | Does not match |
