php - Skip values in case they are empty -


i need skip values in case, empty. data in database looks similary:

gender : man hair : blonde eyes : blue figure : slim   gender : woman hair : blonde eyes : blue figure : slim

when use query:

select * people figure = 'slim' , hair = 'blonde' , eyes = '' , gender = 'man';

it returns me nothing, because eyes empty. data form in php , empty data fields, user don't fill.

can me, how can fix it? driver database use pdo.

you need step through values 1 one:

$sql = "select * people " $appender = ""; if ( !empty($gender) ) {     $sql .= ( $appender . " gender = '" . $gender . "'");     $appender = " , "; } if ( !empty($hair) ) {     $sql .= ( $appender . " hair= '" . $hair. "'");     $appender = " , "; } ... ...

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 edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is)..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