[Phphtmllib-devel] TRtag::push_reference() bug

[David M. <da...@re...>]

Hi again,

When using the push_reference() method in TRtag, it sometimes wraps the
inserted thing even when it's actually a TDtag.

Example:

    $page = new HTMLPageClass("This page");
    $page->push_reference($font);
    $font = new
    FONTtag(array('size'=>'4','face'=>'arial,helvetica,sans-serif'));
    $font->push_reference($table1);
    $table1 = new TABLEtag(array('border'=>1));
    $table1->push_reference($row[0]);
    $table1->push_reference($row[1]);
    
    $row[0] = new TRtag(0);
    $row[0]->push_reference($col[0][0]); // forward reference
    $row[0]->push_reference($col[0][1]); // ditto
    $col[0][0] = new TDtag(0, "Cell A");
    $col[0][1] = new TDtag(0, "Cell B");
    
    $row[1] = new TRtag(0);
    $col[1][0] = new TDtag(0, "Cell C"); // backward reference
    $col[1][1] = new TDtag(0, "Cell D"); // ditto
    $row[1]->push_reference($col[1][0]);
    $row[1]->push_reference($col[1][1]);
    
    print $page->render();

Produces:

    <FONT size="4" face="arial,helvetica,sans-serif">
      <TABLE border="1">
        <TR>
          <TD>
            <TD>Cell A</TD>
          </TD>
          <TD>
            <TD>Cell B</TD>
          </TD>
        </TR>
        <TR>
          <TD>Cell C</TD>
          <TD>Cell D</TD>
        </TR>
      </TABLE>
    </FONT>
 
Note that the data cells in the first row are being incorrectly wrapped
in an extra 'td' tag. This seems to be happening when I push_reference()
on something I haven't defined yet - TRtag is assuming that it won't be
a column object.

Cheers
