php unidentified index error message -


this question has answer here:

since added $city=$_post['city'];

i've been getting error message.

undefined index: city in c:\wamp\www\assignment\html\img_upload.php on line 39.

city select field in form.

this code

<?php     require 'login.php';          $path = 'img/';         if (isset($_post['submit'])) {         // grab image post array         $fn=$_post['fname'];         $ln=$_post['lname'];         $sex=$_post['sex'];         $city=$_post['city'];         $em=$_post['email'];         $pass=$_post['pword'];         $confirm=$_post['cword'];         //$gend = $_post['gender']; not using         $pic = $_files['pic']['name'];         if (!empty($fn) && !empty($ln) && !empty($pic)) {         // move file target upload folder         $target = $path.$pic;//create image source (src)         if (move_uploaded_file($_files['pic']['tmp_name'], $target)) {           // // connect database         $dbase = mysqli_connect('localhost', 'root', '', 'flowers');         // write data database         $my_query = "insert members values ('$fn', '$ln', '$sex','$city','$em','$pass', '$pic');";           mysqli_query($dbase, $my_query);           $result = mysqli_query($dbc, $query);           if ($result){         // // confirm success user         // echo '<p>thank registering us!</p>';         // echo '<p><strong>name:</strong> ' . $fn .' '.$ln .'<br />';         // echo '<img src="' . $path . $pic . '" alt="profile image" /></p>';         // echo '<p><a href="index.html">&lt;&lt; return home page</a></p>';         }         else echo "sorry have error:  ".$mysqli_error($dbc);          }         }         }      ?>

it seems have not posted variable $_post['city'].

whenever have dynamic fields in form, unsure fields posted.

in case, use isset().

$city = isset($_post['city']) ? $_post['city'] : '';

this ensures not notice error.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
