Doesnt save into my PHP

Hi,

I do create normally a table into my database and wrote codes to save in. Curiously when I cliick to save datas its looks like datas have been saved. But when I see into my database nothing appear. My table still blank. Other thing very strange is when I delete its works. Just not for saving.

Please see my codes:

$link=mysqli_connect("localhost:3307","root","");
mysqli_select_db($link,"rhumanos");
?>
Untitled Document
"form1" action="" method="post">
"2" align="center">"submit" name="submit1" value="insert">
"submit" name="submit2" value="delete">


Enter Name "text" name="name">
Enter City "text" name="city">
if(isset($_POST["submit1"]))
{
mysqli_query($link,"insert into name_city values('$_POST[name]','$_POST[city]')");
}
if(isset($_POST["submit2"]))
{
mysqli_query($link,"delete from name_city where name='$_POST[name]'");
}
?>

Enter Name	"text" name="name">
Enter City	"text" name="city">
