    I am currently working with a template that has 2 pages in it and am using the following to populate the $VARIABLES$ within the template:

    [code]
    $filename = 'UnitDesignTemplate-'.str_replace(' ', '', $this->rec->title);
    $document = new CreateDocx();
    $document->addTemplate(dirname(__FILE__).'/templates/unitdesigntemplate.docx');

    $document->addTemplateVariable('LAUNCH', $this->rec->launch_time);
    $document->addTemplateVariable('PLAN', $this->rec->plan_time);
    $document->addTemplateVariable('RTIME', $this->rec->research_time);
    $document->addTemplateVariable('DESKCRIT', $this->rec->desk_crits);
    $document->addTemplateVariable('SHARE', $this->rec->publish_share);
    $document->addTemplateVariable('TTIME', $this->rec->total_time);

    $document->addTemplateVariable('TITLE', $this->rec->title);

    ...

    $document->addTemplateVariable('REQUIREMENTS', $this->rec->requirements, 'html');

    $document->clearBlocks();
    $document->parseStyles();
    $document->createDocx($filename);
    [/code]

    I then push the resulting docx file to the browser and remove the file from the server using:

    [code]
    header("Content-Type: application/vnd.openxmlformats-officedocument.wordprocessingml.document");
    header("Content-Length: ".filesize($filename.'.docx'));
    header('Content-Disposition: attachment; filename='.$filename.'.docx');
    header('Content-Transfer-Encoding: binary');
    readfile($filename.'.docx');
    unlink($filename.'.docx');
    [/code]

    I originally did it this way because the createDocxAndDownload() function was the initial culprit as to why the Word document was coming out corrupted. However, this only worked once and since then has generated files that, when opened in Word (Office Pro Plus 2010, Word version 14.0.6112.5000 64bit), gives the error "The file is corrupt and cannot be opened."

    Does anyone have a clue as to what can be going wrong here?

    After some digging online, I discovered that I needed to do the following immediately prior to the readfile() function:
    [code]
    ob_clean();
    flush();
    [/code]

    Well, that worked all of once and the issue persists.

    Well, I feel dumb. I discovered the problem I was having was related to the output of the docx file. After I unlinked the file, I needed to call [code]exit;[/code], otherwise the top portion of the web interface would get appended to the end of the docx file, resulting in a 'corrupted' file.
