mysql - Access folder and select filename using PHP -


i have written code, user selects profile picture , picture stored in localhost/user/$username/photos/photo1.gif.

after that, assigned filename (photo1.gif) session variable can display php scripts. working fine. can display picture in every php script accessing session variable.

the problem have when trying login login page: in login page connect database, retrieve email , password, check them , if ok redirect user home.php. problem user's photo not linked email cannot know filename of photo. thing know sure directory (because can retrieve username database well).

lets user has uploaded 4 photos (photo1, photo2, photo3, photo4 - photo4 uploaded last). makes sense using photo4 profile picture. there way me access folder , retrieve filename of picture uploaded last?

also, general question, better, store photos(or files) in database or server?

a few options:

it 'better' create photo table , store user_id , photo location in table. storing actual photo in table blob not recommended.

alternatively, avoid more tables, rename photos 

username_photo1.jpg username_photo2.jpg username_photo3.jpg

and can retrieve largest of them.

finally, option file creation date of photos in directory , take recent photo.

see getting filenames of files in folder

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
