This is my table in my database. It should only contain one row.
I have this code, that checks if there is no data , if there is not.. The data is inserted, else it's updated. The problem is, that if i update only Brevet, the value of Baccalaureabt will disappear from my database. Any help?
Code:
if(isset($_POST['submit']))
{ $brevet = $_POST['Brevet'];
$baccalaureatbt = $_POST['Baccalaureatbt'];
$sql1="SELECT Brevet,Baccalaureatbt FROM university";
if ($result=mysqli_query($con,$sql1))
{
$rowcount=mysqli_num_rows($result);
}
if($rowcount==0)
{
$sql="INSERT INTO university(Brevet,Baccalaureatbt) VALUES('$brevet','$baccalaureatbt')";
$result = mysql_query($sql);
}
else
{
$sql2 = "UPDATE university SET Brevet = '$brevet' , Baccalaureatbt = '$baccalaureatbt'";
$result2 = mysql_query($sql2);
}
