I would have thought this would be simple, however, I'm having a hard time with it. I have this function and I'm having a hard time mapping numbers. I have a spreadsheet that I import with WP All Import and utilize this function for a variety of other fields that are not numbers and it works great.

In example, other fields where I use this function is for something like 'Gasoline' => 'Gas' and it maps "Gasoline" to the "Gas" category without any issues, however when using only numbers (2, 4, 6 etc) as seen below, it won't map it to the "X Passenger" category that I have in the database. I hope I'm explaining this appropriately.

Anybody have any thoughts on what I'm doing wrong? Thank you in advance.

function seating_translate_data_sample( $data ) {

    if (empty($data)) {
        echo "Not Specified";

    $map = array(
        '2'  => '2 Passenger',
        '4'  => '4 Passenger',
        '6'  => '6 Passenger',
        '8'  => '8 Passenger',
        '10' => '10 Passenger',

    foreach ( $map as $partial_match => $mapped_value ) {
        if ( stristr( $data, $partial_match ) ) {
            return $mapped_value;
    return $data;
  • It would be helpful if you would edit your question to show us some of the $data that's causing you problems.

I'd guess that $data is being treated as an integer, and therefore your stristr is returning false.

Try explicitly casting $data as a string:

if ( stristr( strval( $data ), $partial_match ) ) {
            return $mapped_value;
