Question

这是我的Php文件代码。当我使用HTML中的输入字段插入数据时，我得到错误无法输入数据。没有选择数据库。

$dbhost="localhost";

$dbuser="root";

$dbpass="";

$conn = mysql_connect($dbhost, $dbuser, $dbpass);

if(! $conn ) {

die('Could not connect: ' . mysql_error());

}

$sql = 'INSERT INTO sale '.
'(Name, Contact, Email, Property_type, Price, Location) '.
'VALUES ( "$a", "$b", "$c", "$d", "$e", "$f" )';

mysql_select_db('gharghar_gharastee');
$retval = mysql_query( $sql, $conn );

if(! $retval ) {

die('Could not enter data: ' . mysql_error());

}

echo "Entered data successfully\n";

mysql_close($conn);

?>

Answer 1

尝试检查与数据库的连接

// make foo the current db
$db_selected = mysql_select_db('gharghar_gharastee', $conn);
if (!$db_selected) {
    die ('Can\'t use gharghar_gharastee : ' . mysql_error());
}

我建议您使用PDO而不是mysql_connect - 出于安全考虑，它已在较新版本的PHP中折旧

你必须像这样使用mysql SQL。

$sql = 'INSERT INTO sale '.
'(Name, Contact, Email, Property_type, Price, Location) '.
"VALUES ( '$a', '$b', '$c', '$d', '$e', '$f' )";

Mysql错误无法输入数据。没有选择数据库
