MySQL PHP部分搜索

-1

我有部分世界搜索問題。MySQL PHP部分搜索

下面的代碼工作，但只適用於全文搜索。如果我只在搜索框中輸入部分單詞，則不起作用。請你能給我一個提示，以便能夠進行部分單詞搜索？

<?php include "connection.php"; 


$sql = "SELECT * FROM Klienci "; 

if (isset($_POST['search'])) { 

    $search_term = mysql_real_escape_string($_POST['search_box']); 

    $sql .= "WHERE nazwaKlienta = '{$search_term}' "; 
    $sql .= " OR adresMail = '{$search_term}' "; 
    $sql .= " OR adresMail2 = '{$search_term}' "; 
} 

$query = mysql_query($sql) or die(mysql_error()); 

?>

您需要使用LIKE或正則表達式。 –

使用'like'和通配符，或查看全文搜索。也不要使用'mysql_ *'再使用'PDO'或'MySQLi'。 https://dev.mysql.com/doc/refman/5.7/en/fulltext-search.html – chris85

如果您在問這裏之前先用盡在線搜索，那麼對您和SO社區都有好處。如果你只是搜索谷歌的這篇文章的標題，你會發現大量的資源來幫助你解決它...說，LIKE關鍵字將是你要找的。 –

下面的代碼應該可以工作。你必須使用LIKE而不是使用平等。例如：WHERE something like'％something2％'

<?php include "connection.php"; 


$sql = "SELECT * FROM Klienci "; 

if (isset($_POST['search'])) { 

    $search_term = mysql_real_escape_string($_POST['search_box']); 

    $sql .= "WHERE nazwaKlienta LIKE '%{$search_term}%' "; 
    $sql .= " OR adresMail LIKE '%{$search_term}%' "; 
    $sql .= " OR adresMail2 LIKE '%{$search_term}%' "; 
} 

$query = mysql_query($sql) or die(mysql_error()); 

?>

您最歡迎:) –

無論如何，您應該避免使用mysql，我建議您學習mysqli或PDO。如果您在較新版本的PHP上運行此代碼，它將無法工作，並且也會使您的站點容易受到SQL注入的攻擊。學習mysqli就像mysql一樣簡單。 –

對@SMJobayerAlam的更新，請注意，mysql作爲數據庫可以使用。 PHP'mysql_ *'函數不應該再被使用了。 – chris85
