I have a mysql table with a firstname, lastname and email which I want to compare with a google spreadsheet array (json) with the same table headers (firstname, lastname, email). If the records match to eachother I want to update my table. For example: I have 'John Doe' in mysql table and 'John Doe' in my google spreadsheet: If this is true I want to update a certain value to this mysql table row.
My code so far, all rows are getting an update because there is one comparison true. I only want the specific rows (Maybe with a foreach?):
$sql = "SELECT * FROM student WHERE form=''"; //select from db
$result = $conn->query($sql);
while($row = mysqli_fetch_array($result)) //fetch it
{
$firstname= $row['firstname'];
$lastname= $row['lastname'];
$email = $row['email'];
$url = 'https://spreadsheets.google.com/feeds/list/*MY-KEY*/od6/public/values?alt=json'; // my spreadsheet (key is inserted with me)
$file= file_get_contents($url);
$json = json_decode($file);
$ress = $json->{'feed'}->{'entry'};
foreach($ress as $res) {
$fname = $res->{'gsx$naam'}->{'$t'};
$lname = $res->{'gsx$achternaam'}->{'$t'};
$mailing = $res->{'gsx$email'}->{'$t'};
}
if ($firstname.$lastname == $fname.$lname || $email == $mailing) {
$sql2 = "UPDATE student SET form=1";
if ($conn->query($sql2) === TRUE) {
echo "inserted";
}
}
}
