displaying search results with two or more queries
- by fusion
in my search form, if the user types 'good', it displays all the results which contain the keyword 'good'. however if the user types in 'good sweetest', it displays no results because there is no record with the two words appearing together; BUT appearing in an entry at different places.
for example, the record says:
A good action is an ever-remaining
store and a pure yield
the user types in 'good', it will show up this record, but if the user types in 'good' + 'pure', it will not show anything. what i would like is that if the user types in 'good' + 'pure' it should records containing these keywords highlighting them.
search.php code:
$search_result = "";
$search_result = $_POST["q"];
$search_result = trim($search_result);
//Check if the string is empty
if ($search_result == "") {
echo "<p class='error'>Search Error. Please Enter Your Search Query.</p>" ;
exit();
}
if ($search_result == "%" || $search_result == "_" || $search_result == "+" ) {
echo "<p class='error1'>Search Error. Please Enter a Valid Search Query.</p>" ;
exit();
}
$result = mysql_query('SELECT cQuotes, vAuthor, cArabic, vReference FROM thquotes WHERE cQuotes LIKE "%' . mysql_real_escape_string($search_result) .'%" ORDER BY idQuotes DESC', $conn)
or die ('Error: '.mysql_error());
function h($s) {
echo htmlspecialchars($s, ENT_QUOTES);
}
function highlightWords($string, $word)
{
$string = preg_replace("/".preg_quote($word, "/")."/i", "<span class='highlight'>$0</span>", $string);
/*** return the highlighted string ***/
return $string;
}
?>
<div class="caption">Search Results</div>
<div class="center_div">

<?php while ($row= mysql_fetch_array($result, MYSQL_ASSOC)) {
$cQuote = highlightWords(htmlspecialchars($row['cQuotes']), $search_result);
