Hello,

Yes, you are right, we didn't test that specific case and it returns an error. The problem comes from the textbox; complex replacements such as replacing a placeholder by a chart in a textbox may require using DOCXPath that is more flexible.

You can use two approaches to fix your issue.

1. Use DOCXPath (it's the easiest solution): instead of the replaceVariableByWordFragment method, you need to use the replaceWordContent one:

<?php

require_once 'classes/MultiMerge.inc';

$docx = new CreateDocxFromTemplate('FBTemplate_Cat.docx');
$chart = new WordFragment($docx, "document");
$data = array(
    'legend' => array('Legend 1', 'Legend 2', 'Legend 3'),
    'data' => array(
        array(
            'name' => 'data 1',
            'values' => array(10, 20, 5),
        ),
        array(
            'name' => 'data 2',
            'values' => array(20, 60, 3),
        ),
        array(
            'name' => 'data 3',
            'values' => array(50, 33, 7),
        ),
    ),
);
$paramsChart = array(
    'data' => $data,
    'type' => 'barChart',
    'color' => 5,
    'sizeX' => 15,
    'sizeY' => 10,
    'chartAlign' => 'center',
    'legendPos' => 'none',
    'legendOverlay' => '0',
    'border' => '1',
    'hgrid' => '1',
    'vgrid' => '0',
    'showTable' => '1'
);
$chart->addChart($paramsChart);

$referenceNode = array(
    'type' => 'paragraph',
    'contains' => 'Ranking_1',
);

$docx->replaceWordContent($chart, $referenceNode);

$docx->createDocx('output_3');

$merge = new MultiMerge();
$merge->mergeDocx('Test_Front_Page.docx', array('output_3.docx'), 'output_2.docx', array());

2. Use the replaceVariableByWordFragment method but first, you merge the DOCX documents and then you replace the placeholder.

Using any of these approaches will generate the correct output.
