php - How to extract variable part from URL and how to know if URL variable is appended by digits? -


i have url this:

www.example.com/education/edu.php?main=colleges&category=engineering-colleges

i rewrite url using .htaccess

www.example.com/education/colleges/engineering-colleges

also have url in same education directory like:

www.example.com/education/edus.php?main=colleges&collegeid=$id&collegename=$name

i want rewrite url this:

www.example.com/education/colleges/$name-sqr$id

how can accomplished? can't think of way because above 2 rewrite urls have same number of parameters. can't redirect them correct page.

these questions:

  • is there way using .htaccess validating url variable sqr$id , redirecting edus.php page.
  • how extract id url , make variable operation in page.

try code in /education/.htaccess:

rewriteengine on rewritebase /education/  rewritecond %{request_filename} -f [or] rewritecond %{request_filename} -d rewriterule ^ - [l]  rewriterule ^([^/]+)/([^-]+)-sqr([0-9]+)/?$ edus.php?main=$1&collegeid=$3&collegename=$2 [l,qsa,nc]  rewriterule ^([^/]+)/([^/]+)/?$ edus.php?main=$1&category=$2 [l,qsa]

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 edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is)..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