Display specific entry of repeatable field

Resolved hephaistos

I am trying to display the first value of a field in a PHP page template, but did not succeed. My code is as follows:
```
<?php
$compositions = pods('composition');
echo $compositions->display('cb-instrument', true);
?>
```
cb-instrument is a repeatable text field. I set the $single parameter of the display() function to “true” following the function documentation, but obviously misunderstood the purose. I expected this statement to output the first entry of the field, but it still displays ALL entries.

How can I output the first, second, nth… entry of a repeatable field? And how can I maybe detect, if a repeatable field has several entries?

Thank you very much
Pascal

<?php

$instruments = pods('composition')->field( 'cb-instrument' );

// This line might not be necessary -- depends on if the array is ID => value or Index => value.
$instruments = array_values( $instruments );

if ( ! empty( $instruments ) ) {
	echo $instruments[0];

	if ( array_key_exists( 1, $instruments ) ) {
		printf(
			'<p>There is a second instrument: %s</p>',
			esc_html( $instruments[1] )
		);
	}

	echo '<ul>';
	foreach( (array) $instruments as $key => $instrument ) {
		if ( 0 === $key ) {
			printf(
				'<li>The first instrument is <code>%s</code></li>',
				esc_html( $instrument )
			);
		}else {
			echo sprintf(
				'<li>Instrument %s is <code>%s</code></li>',
				number_format( $key + 1, 0 ),
				$instrument
			);
		}
	}
	echo '</ul>';
}else {
	echo '<p>This composition is a cappella.</p>';
}
