PHP 高级搜索 - 多个参数

Question

我正在开发高级搜索功能:

$colname_SokvansterImp = "-1"; 

mysql_select_db($database_Audiologiska, $Audiologiska);
if (isset($_POST['Personnummer_search'])) 
{   
    //Visa bara det som söks
     $searchword = $_POST['Personnummer_search'];
    $query_SokvansterImp = "SELECT * FROM patient left join person on person.Personnummer = patient.Patient left join vanster_implantat on vanster_implantat.Patv = patient.Patient WHERE vanster_implantat.patv LIKE '%".$searchword."%'";

}
else//Visa all data
{

    $query_SokvansterImp = "select * from patient left join person on person.Personnummer = patient.Patient left join vanster_implantat on vanster_implantat.patv = patient.Patient";

}
$SokvansterImp = mysql_query($query_SokvansterImp, $Audiologiska) or die(mysql_error());
$row_SokvansterImp = mysql_fetch_assoc($SokvansterImp);
$totalRows_SokvansterImp = mysql_num_rows($SokvansterImp);

这适用于使用一个参数进行搜索，但是，我想知道如何使其接受多个参数？ “Personnummer_search”是我的字段的名称。我怎样才能使它可以搜索例如姓名和/或姓氏？我正在使用 Dreamweaver

添加新的条件 block ？

if (isset($_POST['Personnummer_search'])) 
{   
    //Visa bara det som söks
     $searchword = mysqli_real_escape_string($_POST['Personnummer_search']);
    $query_SokvansterImp = "SELECT * FROM patient left join person on person.Personnummer = patient.Patient left join vanster_implantat on vanster_implantat.Patv = patient.Patient WHERE vanster_implantat.patv LIKE '%".$searchword."%'";

}
else if(isset($_POST['Name_search']) && isset($_POST['Surname_search']))
{
    $name = mysqli_real_escape_string($_POST['Name_search']);
    $surname = mysqli_real_escape_string(($_POST['Surname_search']);
    $query_SokvansterImp = "YOUR SQL QUERY...";

}
else//Visa all data
{
    $query_SokvansterImp = "select * from patient left join person on person.Personnummer = patient.Patient left join vanster_implantat on vanster_implantat.patv = patient.Patient";
}
