OpenTBS/PHP - Merge content into embedded worksheet inside of a PowerPoint template

问题

How do I properly fill an embedded worksheet of a PowerPoint template with data using OpenTBS, where the worksheet is embedded inside of a PowerPoint presentation?

I used sub files but the embedded worksheet retains the input tags and no replaced values.

Excel Template that merges properly as a standalone xls file, but not when embedded in a presentation (PPTX).

+------------------------------+---------------------------------+
|                              |    [c.key;block=tbs:cell]       |
+------------------------------+---------------------------------+
|       [r.#;block=tbs:row]    |    [cell.val;block=tbs:cell]    |
+------------------------------+---------------------------------+

PHP Merge Code

$template = 'riskwaterfalltemplate.pptm';
$TBS->LoadTemplate($template.'#ppt/embeddings/Microsoft_Excel_Worksheet2.xlsx',  OPENTBS_ALREADY_UTF8);


// -----------------
// Output the result
// -----------------
$nbr_row = 5;
$nbr_col = 5;
// List of column's names
$columns = array();
for ($col=1; $col <= $nbr_col; $col++)
{
    $columns[$col]['key'] = $col;
}





$data = array();
$record = array();

for ($col=1; $col <= $nbr_col; $col++)
{
    $record[$col]['val'] = 1;
}
for ($row=0; $row < $nbr_row; $row++)
{

    $data[$row] = $record;
}

// Expanding columns
$TBS->MergeBlock('c',$columns);

//Expanding Cells
$TBS->MergeBlock('cell', $record);

// Merging rows
$TBS->MergeBlock('r',$data);

$TBS->Show();

If you are merging the embedded XLSX in order to have a chart modified in the PPTX Presentation, this will not work.

In both Ms Word ans Ms PowerPoint, embedded XLSX attached to chart does not contains the true data of the chart. It is a simple copy that helps the user for editing the data using Ms Excel. The true data are stored in the XML sub-file related to the chart.

If you want to edit the chart, use command OPENTBS_CHART.

If you actually want to merge the embedded XLSX file, your code is not working because the sub-file ppt/embeddings/Microsoft_Excel_Worksheet2.xlsx is not an XML file, it is a binary file. So TBS cannot merge anything in it directly.

The solution is to:

load the PPTX template using $TBS->LoadTemplate('my_presentation.pptx'),
the load the ppt/embeddings/Microsoft_Excel_Worksheet2.xlsx sub-file as the current sub-file using $TBS->PlugIn(OPENTBS_SELECT_FILE, $SubFile)
save the binary of the XLSX sub-file in a temp file using $handle = tmpfile(); fwrite($handle, $TBS->Source);
open a new TBS instance for this temp file using $TBS2->LoadTemplate($handle);
do your data merging in the XLSX with $TBS2,
finalize the XLSX using $TBS2->Show(OPENTBS_STRING);
save the result in the PPTX using $TBS->Source = $TBS2->Source;
finalize the PPTX using $TBS->Show(...);
