Merging multiple docx files created using templates?

[ozilion]

Hi all,

I would like to know, if possible, how to merge multiple docx files created by TemplateProcessor? I have at least 10 different templates and can create different number of docx files depends on some criterias, it could be 1 or 3 or 5 for example, at the end i have to combine those created docx files into 1 combined docx file. Is it possible with PHPWord?

Thanks in advance.

If you only need to merge content (while maintaining formating/styling), you can use the following approach:

<?php

namespace Template;

use PhpOffice\PhpWord\TemplateProcessor;

class Template extends TemplateProcessor
{
    private const OPEN_BODY_TAG = '<w:body>';
    private const CLOSE_BODY_TAG = '</w:body>';

    public function getBodyContent(): string
    {
        $bodyStart = mb_strpos($this->tempDocumentMainPart, self::OPEN_BODY_TAG) + mb_strlen(self::OPEN_BODY_TAG);
        $bodyEnd = mb_strpos($this->tempDocumentMainPart, self::CLOSE_BODY_TAG, $bodyStart);

        $bodyContent = mb_substr($this->tempDocumentMainPart, $bodyStart, $bodyEnd - $bodyStart);

        return $bodyContent;
    }

    public function mergeXmlBody(string $xmlBody): void
    {
        $this->tempDocumentMainPart = str_replace(
            self::CLOSE_BODY_TAG,
            $xmlBody . self::CLOSE_BODY_TAG,
            $this->tempDocumentMainPart
        );
    }
}

How to use:

<?php

function merge(array $files): string
{
    $mergedFile = str_replace(basename($files[0]), time() . '_merged.docx', $files[0]);
    $main = new \Template\Template($files[0]);
    unset($files[0]);

    $body = [];

    foreach ($files as $file) {
        $template = new \Template\Template($file);
        $body[] = $template->getBodyContent();
    }

    $body = implode('', $body);

    $main->mergeXmlBody($body);
    $main->saveAs($mergedFile);

    return $mergedFile;
}
