You can do one thing use textbox to input letters.
THen retrive textbox value and then put in the like clause of your select query
Ex:

"SELECT * FROM students where
idnum = '$_GET[mysearch]' or 
fname = '$_GET[mysearch]' or 
lname = '$_GET[mysearch]' or
midin = '$_GET[mysearch]' or 
gender = '$_GET[mysearch]' or 
bdate = '$_GET[mysearch]' or
course = '$_GET[mysearch]' or
year = '$_GET[mysearch]' or
address = '$_GET[mysearch]' or
cnum ='$_GET[mysearch]' and fname like '$_GET[textbox_val]"

thanks avinanuami, but what about i constraint the case. if i search lowercase letter it will only show lowercase letter save on database content.
