If you need to allow all digit or all alphabet inputs as well

You just need ^[A-Za-z0-9]{7,}$ which would accept any character from A to Z or a to z or 0 to 9 (denoted by the character class) occurring 7 or more times.

If you need to allow only if at least one digit and one alphabet is there

Use ^(?=.*[A-Za-z].*)(?=.*[0-9].*)[A-Za-z0-9]{7,}$, which has look-aheads for alphabet (?=.*[A-Za-z].*) and digit (?=.*[0-9].*) to confirm that at least a digit and an alphabet is there, followed by a character class to restrict the characters to alphabets and letters set with a minimum length of 7.
