Textarea

Textarea Field

The Textarea field is a multi-line text input for longer content — descriptions, excerpts, biography text, or any content that spans multiple lines.

Field Key	Unique identifier. Lowercase letters and underscores only.
Label	Display label shown above the field.

Return Value

Returns a string. Line breaks are preserved in the raw value.

Usage

php

// Get the value
$content = onemeta_get_meta( get_the_ID(), 'field_key' );

// Display raw with line breaks converted to <br>
echo nl2br( esc_html( $content ) );

// Display as paragraphs (WordPress auto-formatting)
echo wp_kses_post( wpautop( $content ) );

// Display escaped
echo esc_html( $content );

Template Example

php

<?php $bio = onemeta_get_meta( get_the_ID(), 'author_bio' ); ?>

<?php if ( ! empty( $bio ) ) : ?>
    <div class="author-bio">
        <?php echo wp_kses_post( wpautop( $bio ) ); ?>
    </div>
<?php endif; ?>

Notes

• Use wpautop() to convert double line breaks to <p> tags
• Use nl2br() to convert single line breaks to <br> tags
• Use wp_kses_post() to allow basic HTML while stripping unsafe tags
• Do not use esc_html() after wpautop() — it will escape the HTML tags
