Regarding the problem of adding data to mysql using php

Question

<?php

include("config.php");

$From=$_POST['Kname'];

$User=$_POST ['Qtime'];

$Skind=$_POST['Ytime'];

$Belong=$_POST['Xname'];

if($From!=""){

$sql="INSERT INTO server(id,From,User,Skind,Belong ) VALUES ('','$From','$User','$Skind','$Belong')";

if(mysql_query($sql)){

echo"<script>alert('Added successfully!'); javascript:window.location.href=document.referrer;</script>";

}

else{

echo "Upload failed!";

}

}else

{

echo "The data is empty";

}

?>

The above cannot be solved by adding data to the database

Answer 1

First check to see if the form value has been passed. If so, print the SQL statement to see if there are any syntax errors.
