mysql - PHP for loop update database images -


i using loop validate page in php using move_uploaded_file move uploaded file + add image path database. below code.

if(empty($_files) === false) { for($i=1; $i<=$items; $i++) {      $allowed = array('jpg', 'jpeg', 'gif', 'png');    if (empty($_files['photo{$i}']['name']) === true) {       echo '<div class="alert alert-danger">please choose file.</div>';   } else {       if (in_array(strtolower(end(explode('.', $_files['photo{$i}']['name']))), $allowed) === false) {       echo '<div class="alert alert-danger">[photo '.$i.'] format <strong>not</strong> acceptable. ';       echo 'accepted formats: '. implode(', ', $allowed).'</div>';       } elseif($_files["photo{$i}"]['size'] > 1048576) {       echo '<div class="alert-danger">[photo '.$i.'] image big. maximium file size 1mb.</div>';       } else {         mysqli_query($con, "update temp set photo{$i} = '".rand(0,999).".".in_array(strtolower(end(explode('.', $_files['photo{$i}']['name']))))."' session = $session");         move_uploaded_file($_files["photo{$i}"]['tmp_name'], 'img/temp/'.rand(0,999) . '.' . in_array(strtolower(end(explode('.', $_files['photo{$i}']['name'])))));       }   }   } }

the image doesn't move desired uploaded location , not update file path in database. please can help?

everywhere have 'photo{$i}' incorrect. elitechief21 explained in comment above, php not parse variables in single quotes., literally looking key photo{$i} in $_files, treating {$i} literal text. of course, doesn't exist, script doesn't work expected.

you need use double quotes wherever photo{$i} inside single quotes.

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 edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is)..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