seach php/mysql - blank output

engima · June 23, 2010

hi guys,

i'n new here and to php, so i followed the tutorial on this site about a search script.

I used the following code:

<?php

$dbHost = 'localhost';
$dbUser = 'username';
$dbPass = 'password';
$dbDatabase = 'test';
$con = mysql_connect($dbHost, $dbUser, $dbPass) or trigger_error("Failed to connect to MySQL Server. Error: " . mysql_error());

mysql_select_db($dbDatabase) or trigger_error("Failed to connect to database {$dbDatabase}. Error: " . mysql_error());

mysql_select_db($dbDatabase) or trigger_error("Failed to connect to database {$dbDatabase}. Error: " . mysql_error());

// Set up our error check and result check array
$error = array();
$results = array();

// First check if a form was submitted.
// Since this is a search we will use $_GET
if (isset($_GET['search'])) {
   $searchTerms = trim($_GET['search']);
   $searchTerms = strip_tags($searchTerms); // remove any html/javascript.

   if (strlen($searchTerms) < 3) {
      $error[] = "Search terms must be longer than 3 characters.";
   }else {
      $searchTermDB = mysql_real_escape_string($searchTerms); // prevent sql injection.
   }

   // If there are no errors, lets get the search going.
   if (count($error) < 1) {
      $searchSQL = "SELECT 'A A A', 'B B', 'C', 'DD' FROM table WHERE ";

      // grab the search types.
      $types = array();
      $types[] = isset($_GET['A A A'])?"`A A A` LIKE '%{$searchTermDB}%'":'';
      $types[] = isset($_GET['B B'])?"`B B` LIKE '%{$searchTermDB}%'":'';
      $types[] = isset($_GET['C'])?"`C` LIKE '%{$searchTermDB}%'":'';
      $types[] = isset($_GET['D D'])?"`D D` LIKE '%{$searchTermDB}%'":'';


      $types = array_filter($types, "removeEmpty"); // removes any item that was empty (not checked)

      if (count($types) < 1)
         $types[] = "`Service ID` LIKE '%{$searchTermDB}%'"; // use the body as a default search if none are checked

          $andOr = isset($_GET['matchall'])?'AND':'OR';
      $searchSQL .= implode(" {$andOr} ", $types) . " ORDER BY `C`"; // order by title.

      $searchResult = mysql_query($searchSQL) or trigger_error("There was an error.<br/>" . mysql_error() . "<br />SQL Was: {$searchSQL}");

      if (mysql_num_rows($searchResult) < 1) {
         $error[] = "The search term provided {$searchTerms} yielded no results.";
      }else {
         $results = array(); // the result array
         $i = 1;
         while ($row = mysql_fetch_assoc($searchResult)) {
            $results[] = "{$i}: {$row['A A A A']}<br />{$row['B B']}<br />{$row['C']}<br />{$row['D D']}<br /><br />";
            $i++;
         }
      }
   }
}

function removeEmpty($var) {
   return (!empty($var));
}
?>
<html>
   <title>My Simple Search Form</title>
   <style type="text/css">
      #error {
         color: red;
      }
   </style>
   <body>
      <?php echo (count($error) > 0)?"The following had errors:<br /><span id=\"error\">" . implode("<br />", $error) . "</span><br /><br />":""; ?>
      <form method="GET" action="<?php echo $_SERVER['PHP_SELF'];?>" name="searchForm">
         Search For: <input type="text" name="search" value="<?php echo isset($searchTerms)?htmlspecialchars($searchTerms):''; ?>" /><br />
         Search In:<br />
         A A A: <input type="checkbox" name="A A A" value="on" <?php echo isset($_GET['A A A'])?"checked":''; ?> /> |
         B B: <input type="checkbox" name="B B" value="on" <?php echo isset($_GET['B B'])?"checked":''; ?> /> |
         C: <input type="checkbox" name="C" value="on" <?php echo isset($_GET['C'])?"checked":''; ?> /><br />
                 Match All Selected Fields? <input type="checkbox" name="matchall" value="on" <?php echo isset($_GET['matchall'])?"checked":''; ?><br /><br />
         <input type="submit" name="submit" value="Search!" />
      </form>
      <?php echo (count($results) > 0)?"Your search term: {$searchTerms} returned:<br /><br />" . implode("", $results):""; ?>
   </body>
</html>

when i use the script the output just show's:

1: A A A

B B

C

D D

2: A A A

B B

C

D D

But not the contence of the table, just the name of the search sting/value.

can anyone help me, or point me in the right direction on what i'm doing wrong?

cheers!
