SettingsUISchema::should_promote_to_integer │ private static │ WC 1.0

Whether a legacy number follows the HTML integer step contract.

Promotion happens only when the step is 1 and every quantity the integer path will later canonicalize — the stored value and the min/max bounds — is itself integral. A step=1 control holding a decimal value or bound (which the classic sanitizer never rejected) stays a 'number' field, so integer canonicalization does not throw and collapse the section into the fallback.

Method of the class: SettingsUISchema{}

No Hooks.

Returns

bool.

Usage

$result = SettingsUISchema::should_promote_to_integer( $field ): bool;
