php - Making incorrect URL's default to database value -


imagine value in database - e.g. raquel_welch - represents page url (e.g. mysite/people/raquel_welch). imagine if types in url incorrectly, of following...

mysite/people/raquel welch mysite/people/raquel_welch mysite/people/raquel welch

in other words, url spelled correctly, letter case wrong and/or there's no underscore. rather fetch 404 error page, i'd url default proper url - mysite/people/raquel_welch

does know how this?

incidentally, wikipedia has similar feature; if type in url without underscore, default proper url, though doesn't appear work cases... http://en.wikipedia.org/wiki/raquel welch

rather automatically capitalize first letter of each word, think i'd prefer have url default value in database.

look key url case-and-underscore insensitively (this requires storing normalized version in db, instance lowercase , underscores), , if url doesn't match canonical version, send 301 redirect canonical path.

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 edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is)..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
