Variables into spin

Hi

Im trying to import a csv with a spintax, i have a very similar issue that this topic https://ww.wp.xz.cn/support/topic/variable-data-not-recognized-with-nested-spintax/

It doesnt recognize de variable, https://prnt.sc/6zODDjF1OCfO

I have this 3 functions

function my_process_spintax( $text ) {
return preg_replace_callback( ‘/\{(((?>[^\{\}]+)|(?R))*)\}/x’, ‘my_replace_spintax’, $text );
}

function my_replace_spintax( $text ) {
$text = my_process_spintax( $text[1] );
$parts = explode( ‘|’, $text );
return $parts[ array_rand( $parts ) ];
}

function my_custom_spintax( $text1 = ”, $options ) {
$output = ”;
$output .= my_process_spintax( $text1 ) . ‘ ‘;
$options = ‘{‘ . implode( ‘|’, $options ) . ‘}’;
$output .= my_process_spintax( $options );
return trim( $output );
}

[my_custom_spintax({descripcin[1]},array({nombre216[1]},{rating[1]}))]

How can i keep the variable in the spintax so wp all import can replace for the value in the csv? Can someone help me?

Thank you so much in advance
