Question

我有部分世界搜索的问题。

以下代码有效，但仅限全字搜索。如果我只将部分单词放在搜索框中，则它不起作用。请你能给我一些提示，以便能够进行部分单词搜索吗？

<?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());

?>

Answer 1

以下代码应该有效。你必须使用LIKE而不是使用相等。例如：什么东西像'％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());

?>
