Custom fileds

Hi,

I want to create 4 additional custom fields in the Details section but I was only able to show one in the admin and website.

Is not posiible to add more than one custom filed?

I copied this code in functions.php

`add_filter( ‘auto_listings_metabox_details’, function ( $fields ) {
$prefix = ‘_al_listing_’;
$fields[4] = array(
‘name’ => __( ‘Equipamiento’, ‘auto-listings’ ),
‘desc’ => __( ‘A custom description’, ‘auto-listings’ ),
‘id’ => $prefix . ‘equipamiento’,
‘type’ => ‘textarea’,
);
return $fields;
} );

add_filter( ‘auto_listings_details_array’, function( $fields ) {
$fields[ ‘Equipamiento’ ] = auto_listings_meta( ‘equipamiento’ );
return $fields;
} );

// a?dir campo cilindrada en detalles

add_filter( ‘auto_listings_metabox_details’, function ( $fields ) {
$prefix = ‘_al_listing_’;
$fields[4] = array(
‘name’ => __( ‘Cilindrada’, ‘auto-listings’ ),
‘desc’ => __( ‘A custom description’, ‘auto-listings’ ),
‘id’ => $prefix . ‘cilindrada’,
‘type’ => ‘text’,
);
return $fields;
} );

add_filter( ‘auto_listings_details_array’, function( $fields ) {
$fields[ ‘Cilindrada’ ] = auto_listings_meta( ‘cilindrada’ );
return $fields;
} );

// a?adir campo puertas en detalles

add_filter( ‘auto_listings_metabox_details’, function ( $fields ) {
$prefix = ‘_al_listing_’;
$fields[4] = array(
‘name’ => __( ‘Puertas’, ‘auto-listings’ ),
‘desc’ => __( ‘numero de puertas’, ‘auto-listings’ ),
‘id’ => $prefix . ‘puertas’,
‘type’ => ‘number’,
);
return $fields;
} );

add_filter( ‘auto_listings_details_array’, function( $fields ) {
$fields[ ‘Puertas’ ] = auto_listings_meta( ‘puertas’ );
return $fields;
} );

// a?adir campo plazas en detalles

add_filter( ‘auto_listings_metabox_details’, function ( $fields ) {
$prefix = ‘_al_listing_’;
$fields[4] = array(
‘name’ => __( ‘Plazas’, ‘auto-listings’ ),
‘desc’ => __( ‘numero de plazas’, ‘auto-listings’ ),
‘id’ => $prefix . ‘plazas’,
‘type’ => ‘number’,
);
return $fields;
} );

add_filter( ‘auto_listings_details_array’, function( $fields ) {
$fields[ ‘Plazas’ ] = auto_listings_meta( ‘plazas’ );
return $fields;
} );

What is wrong?

Thanks
