    You showed me how to write a filter to wrap code around the table cells
    What I want to do is take a value from row1 and update row 3 with it
    This is the code I came up with but it does not work – do you know why?

    //***Custom TablePress Table 60**/
add_filter( 'tablepress_cell_content', 'Table60', 10, 4 );
function Table60( $tablepress_cell_content, $table_id, $row_number, $column_number )
    {
    if ($table_id==60)
        {
        if ($row_number!=1)
            {
            if ($column_number==1)
                {
                global $fernname;
                $temp1=strip_tags($tablepress_cell_content);
                $fernname=str_replace(" ","_",$temp1);
                }
            if ($column_number==3)
                {
                $tablepress_cell_content=$fernname;
                }
            }
        }
    return $tablepress_cell_content;
    }

    Hi Andrew,

    thanks for your question, and sorry for the trouble.

    You’ll just have to add global $fernname; in the second if-condition (for the 3) as well (or move it to the top of the function).

    Regards,
    Tobias

    Ugh
    It is not working quite as I expected!
    You can see here:
    https://ebps.org.uk/ferns-2/indentification/hectad-page-v2/
    I was expecting it to store the contents of column 1 and put it into column 3 of the same row, but it seems to be putting the contents of column one from the next row into column 3?

    Hi,

    ah, yes… The reason or this is how the table is rendered. The rendering basically starts in the last row (because TablePress needs to check for keywords like #rowspan# and #colspan# from the bottom up.

    The best approach here should therefore be to use a different filter hook, like tablepress_table_render_data, and loop through the table array there.

    where would I find the instructions for how to use this filter?

    Hi,

    that filter is defined in the class-render.php file, see https://github.com/TobiasBg/TablePress/blob/master/classes/class-render.php#L251

    You would register a function to that hook in the same way as with the tablepress_cell_content, like

    add_filter( 'tablepress_table_render_data', 'andrew_filter_table', 10, 3 );
function andrew_filter_table( $table, $orig_table, $render_options ) {
  ...
  return $table;
}

    Tobias

    I will look tomorrow
    For tonight I “swapped” column 3 to column 1 and column 1 to column 2
    This way it looks at column 2 before column 1 and it works OK!

    Hi,

    that’s also a nice trick. ??
    If there’s something else here where I can help, just let me know.

    Best wishes,
    Tobias
