java - How to set plain header in docx file using apache poi? -

-

i create header docx document using apache poi have difficulties. have no working code show. ask piece of code starting point.

there's apache poi unit test covers case - you're looking testxwpfheader#testsetheader(). covers starting document no headers or footers set, adding them

your code like:

xwpfheaderfooterpolicy policy = sampledoc.getheaderfooterpolicy(); if (policy.getdefaultheader() == null && policy.getfirstpageheader() == null        && policy.getdefaultfooter() == null) {    // need create new headers    // easy way, gives single empty paragraph    xwpfheader headerd = policy.createheader(policy.default);    headerd.getparagraphs(0).createrun().settext("hello header world!");     // or full control way     ctp ctp1 = ctp.factory.newinstance();     ctr ctr1 = ctp1.addnewr();     cttext t = ctr1.addnewt();     t.setstringvalue("paragraph in header");      xwpfparagraph p1 = new xwpfparagraph(ctp1, sampledoc);     xwpfparagraph[] pars = new xwpfparagraph[1];     pars[0] = p1;      policy.createheader(policy.first, pars); } else {    // has header, change }

see xwpfheaderfooterpolicy javadocs bit more on creating headers , footers.

it isn't nicest, ideally use kind soul submitting patch make nicer (hint hint...!), can work unit tests show

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
