php - regex find input value -

-

the string is:

<input type="hidden" name="billing[address_id]" value="34543" id="billing:address_id" />

how can input value string? tried code:

preg_match('/<input type="hidden" name="billing[address_id]" value="(.*?)" id="billing:address_id" \/>/mis', $html, $results);

your regex correct.. escape [ , ] @ address_id.

preg_match('/<input type="hidden" name="billing\[address_id\]" value="(.*?)" id="billing:address_id" \/>/mis', $html, $results);

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...

c++ - Rendering a QGraphicsScene to QImage results in objects being placed on a side of QImage -

my qgraphicsscene quite large, , qgraphicsview fit small portion of it. i print/save qgraphicsscene outputview::outputview(qwidget *parent) : qgraphicsview(parent) {...} void outputview::savetoimage() { qimage image(scene()->scenerect().size().tosize(), qimage::format_mono); image.fill(qt::transparent); qpainter painter(&image); render(&painter); image.save("output.png"); } of course experimenting, placing objects in center of viewport... the saved image contains objects, location of objects on left side of image input: output: (screenshot windows photo viewer) it seems image created correct size, viewport contents rendered - top left corner of viewport on top left corner of image, leaving rest of image empty. why happening ? doing wrong ? update: trying fitinview(scene()->scenerect()); results in viewport showing entire image, zoomed ... saved image still contains viewport (only tiny) and answ...
