我想弄清楚在這段代碼中出了什麼問題。它要麼不突出顯示搜索結果,要麼輸出圍繞突出顯示的文本的html標籤。 。突出顯示在php錯誤中的搜索結果

$search_result = ""; 
$search_result = trim($search_result); 

$special_cases = array('%', '_', '+'); 
$search_result = str_replace($special_cases, '', $_GET["q"]); 


//Check if the string is empty 
if ($search_result == "") { 
    echo "<p>Search Error</p><p>Please enter a search...</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()); 

//eliminating special characters 
function h($s) { 
    echo htmlspecialchars($s, ENT_QUOTES); 
} 

function highlightWords($string, $word) 
{ 

     $string = str_replace($word, "<span style='background-color: #FFE066;font-weight:bold;'>".$word."</span>", $string); 
    /*** return the highlighted string ***/ 
    return $string; 

} 

?> 

<div class="caption">Search Results</div> 
<div class="center_div"> 
<table> 
    <?php while ($row= mysql_fetch_array($result, MYSQL_ASSOC)) { 
     $cQuote = highlightWords($row['cQuotes'], $search_result); 
     ?> 
     <tr> 
     <td style="text-align:right; font-size:15px;"><?php h($row['cArabic']); ?></td> 
      <td style="font-size:16px;"><?php h($cQuote); ?></td> 
      <td style="font-size:12px;"><?php h($row['vAuthor']); ?></td> 
      <td style="font-size:12px; font-style:italic; text-align:right;"><?php h($row['vReference']); ?></td> 
     </tr> 
    <?php } ?> 
</table> 
</div> 
上的瀏覽器

,它被輸出作爲:

A good <span style='background-color: #FFE066;font-weight:bold;'>action</span> is an ever-remaining store and a pure yield 

,或者如果一個div使用具有類:

A good <div class='highlight'>action</div> is an ever-remaining store and a pure yield

html標籤顯示爲輸出,而不是格式化並突出顯示關鍵字。 – input 2010-04-30 21:03:44

你的輸出功能h()被逸出所有的HTML字符( htmlspecialchars

更改:

$cQuote = highlightWords($row['cQuotes'], $search_result); 

要:

$cQuote = highlightWords(htmlspecialchars($row['cQuotes']), $search_result); 

而變化:

<td style="font-size:16px;"><?php h($cQuote); ?></td> 

要:

<td style="font-size:16px;"><?php echo $cQuote ?></td>
