FieldtypeEmail

string — a valid email address, or empty string '' when blank.

// Get
$page->email_field  // string, e.g. "user@example.com"

// Set
$page->email_field = 'user@example.com';
$page->email_field = '';  // clear
$page->save('email_field');

Values are sanitized through $sanitizer->email() — invalid addresses become blank.

Supports the same string operators as FieldtypeText:

$pages->find('email_field=user@example.com');
$pages->find('email_field=""');           // no email
$pages->find('email_field*=example.com'); // contains
$pages->find('email_field$=.org');        // ends with

echo '<a href="mailto:' . $page->email_field . '">' . $page->email_field . '</a>';

Apply TextformatterEntities (recommended) or entity-encode manually before HTML output.

• Invalid email addresses are sanitized to blank.
• allowIDN=1 field setting permits internationalized domain names.
• A unique index option prevents duplicate email addresses across pages.
• Database column: varchar NOT NULL (length = DB max index length, typically 191–255).
• Compatible fieldtypes: any fieldtype extending FieldtypeText.
