Answer 1

The only answer i can suggest you that instead of using MYSQL just use MYSQLI/ PDO because MYSQL is deprecated.
In your current code if you have error reporting on so you will sure not get error message but MYSQL deprecation warning message will be there.

Answer 2

The Signup page is not registering the details and details are not
being saved in table called member and also its showing no error in
the signup page post submit
The table name is called "member" right ? . And your sql query says "members"
$sql="INSERT INTO members(user,pass,fname,lname,number,gender,college) VALUES('$user','$pass','$fname','$lname','$number','$gender','$college')";
hence it will not work. But yeah, important things you need to know, Like ec45 said...
1.mysql_...() is deprecated. Use PDO instead and if you really love the mysql function, use mysqli...()
2.Never ever directly use values gotten from a form in an SQL query as it leaves you vulnerable to SQL injection. Use prepared statements .
3.Please write clean PHP code. Stuff like this is why people abuse PHP . Best regards.
Okay, i tried to quickly write a PDO version of your script . Here it is. Test it and it should work, also check that the correct column names in your databse are represented in your SQL query. Best regards
<?php

//this is PDO . Easier, and better.

//function to insert user into the database

//first check to ensure its a new user. If its a new user, we carry normal activities else, echo error message

//helps to check if a user has already been registered
function checkUser($email){
//watch the next few lines. Showcases the prepared statements
$sql="SELECT * FROM members WHERE user = ?";
$data=array($email);
$db->prepare($sql);
$prepared=$db->execute($data);
$result=(($prepared->rowCount() > 0) ? true :false );
return $result;
