I'm trying to write a simple, full text search with PHP and PDO. I'm not quite sure what the best method is to search a DB via SQL and PDO. I found this this script, but it's old MySQL extension. I wrote this function witch should count the search matches, but the SQL is not working. The incoming search string look like this: 23+more+people
function checkSearchResult ($searchterm) {
//globals
global $lang; global $dbh_pdo; global $db_prefix;
$searchterm = trim($searchterm);
$searchterm = explode('+', $searchterm);
foreach ($searchterm as $value) {
$sql = "SELECT COUNT(*), MATCH (article_title_".$lang.", article_text_".$lang.") AGINST (':queryString') AS score FROM ".$db_prefix."_base WHERE MATCH (article_title_".$lang.", article_text_".$lang.") AGAINST ('+:queryString')";
$sth = $dbh_pdo->prepare($sql);
$sql_data = array('queryString' => $value);
$sth->execute($sql_data);
echo $sth->queryString;
$row = $sth->fetchColumn();
if ($row < 1) {
$sql = "SELECT * FROM article_title_".$lang." LIKE :queryString OR aricle_text_".$lang." LIKE :queryString";
$sth = $dbh_pdo->prepare($sql);
$sql_data = array('queryString' => $value);
$sth->execute($sql_data);
$row = $sth->fetchColumn();
}
}
//$row stays empty - no idea what is wrong
if ($row > 1) {
return true;
}
else {
return false;
}
}
