On clicking submit button the user information get stored in applicant table in abcdef database. error : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1

回答1:

You seem to have an extra comma in you columns and your table name in quotes, try changing this line:

$sql="INSERT INTO 'applicant' (user,name,number,) VALUES('$user','$name','$number')";

To this

$sql="INSERT INTO applicant (user,name,number) VALUES('$user','$name','$number')";

I believe the issue is here (user,name,number) and here 'applicant'

回答2:

Try removing the quote marks from the table names so for example:

$result3 = mysql_query("SELECT * FROM 'members' where user='$user'");

becomes:

$result3 = mysql_query("SELECT * FROM members where user='$user'");
