html - Issue accessing results with PHP from an SQL database which was working yesterday. Also, need advice for injection proofing -


this question has answer here:

this working second ago. can't life of me figure out went wrong.

error: warning: mysqli_fetch_array() expects parameter 1 mysqli_result, boolean given in c:\xampp\htdocs\phpproject1\results.php on line 25

    <!doctype html>     <html>     <head>         <link type="text/css" rel="stylesheet" href="stylesheet.css"/>         <title>find me goods</title>     </head>      <body>         <a href="form.php" id="help">help other people find goods</a>         <div class="container">      <?php     error:warning: mysqli_fetch_array() expects parameter 1 mysqli_result, boolean given in c:\xampp\htdocs\phpproject1\results.php on line 25   require("config.php");       if(isset($_post['submit'])){     $searchterm = $_post['searchterm'];     }       $result = mysqli_query($dbconn,"select * input country or region or towncity = '$searchterm'");       while($row = mysqli_fetch_array($result))       {     echo"<div id=resultsbox>";     echo "<p id='date'>" . $row['thedate'] . "</p>";      echo "<table border='0' id='resultstable'>";        echo "<tr><td><span>" . $row['towncity'] . "</span></td></tr>";       echo "<tr><td>" . $row['region'] . "</td></tr>";       echo "<tr><td>" . $row['country'] . "</td></tr>";      echo "</table>";       echo "<h1>public smoking tolerance:" . " " . $row['tolerance'] . "/5</h1>";       echo "<h1>relevant laws:</h1><p>" . $row['laws'] . "</p>";       echo "<h1>where go find it:</h1><p>" . $row['wherefind'] . "</p>";       echo "<h1>what expect pay:</h1><p>" . $row['price'] . "</p>";       echo "<h1>addition information:</h1><p>" . $row['information'] . "</p>";     echo"</div>";        }       ?>       </div>       </body>      </html>

that error means mysqli returned empty result set. before while loop, should add:

if(empty($result)){     echo "no results found."; }else{     // while loop goes here }

as far making sure mysqli queries secure goes, bit of reading. here few useful stack overflow sources:
