Multi word search in PHP/MySQL

Question

I\'m struggling to create a search that searches for multiple words. My first attempt yielded no results whatsoever and is as follows:

  require_once(\'datab         


        

Answer 1

here's what i did

if (isset($_POST['search'])){
$words = mysql_real_escape_string($_POST['searchfield']);   
$arraySearch = explode(" ", trim($words));       
$countSearch = count($arraySearch);
$a = 0;
$query = "SELECT * FROM parts WHERE ";
$quote = "'";
while ($a < $countSearch)
{
  $query = $query."description LIKE $quote%$arraySearch[$a]%$quote ";
  $a++;
  if ($a < $countSearch)
  {
    $query = $query." AND ";
    }   
  }
    $result=mysql_query($query) or die(error);

//you could just leave it here, short and sweet but i added some extra code for if it doesnt turn up any results then it searches for either word rather than boths words//

$num = mysql_num_rows($result);
if ($num == 0){
 $a = 0;
 $query = "SELECT * FROM parts WHERE ";
while ($a < $countSearch)
{
  $query = $query."description LIKE $quote%$arraySearch[$a]%$quote ";
  $a++;
  if ($a < $countSearch)
  {
    $query = $query." OR ";
    $msg = "No exact match for: $words. Maybe this is what you're looking for though? If not please try again.";
    }

  }
  }
  $result=mysql_query($query) or die($query);
  if (mysql_num_rows($result) == 0){
    $msg = "No results, please try another search";
    }

}
