所以基本上我試圖讓搜索採取標題,然後在搜索中忽略標題,但採取關鍵字與該標題相關聯,並顯示其他項目具有相同的關鍵字,如果這是有道理的。PHP搜索查詢不起作用
這是我的代碼,但它只搜索你輸入的內容。我不知道如何讓它做我想要的。
<?php
$k = $_GET['lookfor'];
$terms = explode(" ",$k);
$query = "SELECT * FROM search WHERE ";
foreach ($terms as $each) {
$i++;
if ($i == 1)
$query .= "keywords LIKE '%$each%' ";
else
$query .= "OR keywords LIKE '%$each%' ";
}
// connect
mysql_connect("localhost", "root", "password");
mysql_select_db("icarus");
$query = mysql_query($query);
$numrows = mysql_num_rows($query);
if ($numrows > 0) {
while ($row = mysql_fetch_assoc($query)){
$id = $row['id'];
$title = $row['title'];
$description = $row['description'];
$keywords = $row['keywords'];
$link = $row['link'];
echo "<li type='1'><h3><a href='$link'>$title</a></h3>
<p>$description</p><br /><br /></li>";
}
}
else
echo "<p>No results found for '<b>$k</b>'. Icarus is still in the early development stage, this can happen.</p>";
// disconnect
mysql_close();
?> </div>

你是什麼意思'拿冠軍的意思,然後在搜索忽略標題而是採取關聯關鍵字' – urfusion
請添加表格定義和一些示例數據 –
我的意思是不顯示與搜索關鍵字相似的標題,但只顯示具有相似關鍵字的標題 –
