Currently MyPmWiki uses a single database model. The administrator has control over which server and database will be used as well as table formatting. With appropriate markup, it would be possible to allow the author to select the server, user, and database as well as format the result table.

This is my first pmwiki addition. I adopted the script from pmwiki-1. There are a lot of expansion possible, it is only a hack!

This is a very nice extension, however the display look causes an error when the SQL query returns no result. philippe? January 11, 2005, at 16:18 AM

I've modified the code a bit to have different background color for odd rows

    $resultStr = "<table $MyPmWiki_TableFmt style=\"border-collapse: collapse;\"><tr>";
    for ($i = 0; $i < mysql_num_fields($result); $i++) {
      $resultStr .= "<th>".mysql_field_name($result, $i)."</th>";
    $resultStr .= "</tr>";
    $x = 1;
    while($row = mysql_fetch_row($result)) {
      $resultStr .= "<tr>";
      if($x%2): $color = "#dee"; else: $color = "#eed"; endif;
      foreach ($row as $field) {
        $resultStr .= "<td style=\"background-color: ".$color."\">$field</td>";	
      $resultStr .= "</tr>";
    $resultStr .= "</table>";

    I added variables in Markup that override defaults in local/config.php.
    I.e., if these variables are not specified in the directive they will
    default to the variables defined in local/config.php for MyPmWiki.
    This allows you to use multiple databases and table formats in one pmwiki
    The variables are the same as the ones above but in lowercase and without
    the MyPmWiki part so they are:
    sql (new variable, required due to the need to quote the sql string.  This
    may be not strictly necessary (one could join the array of all strings not
    in other variable assignments), but in my opinion it is not a burden to use
    the new variable.)
    Example usage would be:

    (:MyPmWiki hostname="localhost" dbname="pmwiki" sql="select * from mytable where name='wiki';":)
    The code is hereΔ.

This is a helpful script.

  • I think that the two instances of "local.php" above should read "local/config.php".
  • Here is the table format I use. It helps make the table more readable.
       $MyPmWiki_TableFmt = 'border="1" cellpadding="6" frame="box" rules="rows"
         style="border-collapse: collapse; font-family:Times New Roman; font-size:10pt"';
  • More information about the MySQL SELECT statement is available here.

Just needed, because it is only on a local PC, it works fine, after upgrading to mysqli and taking care of the forbidden /e swich in regexps. ;-)
