[SOLVED] ereg HELP ...

[shakeit]

Hello everybody... You've helped me out a couple of times and I am still comming back :-)

 

I need some help on a ereg issue, where I want to make a function where ONLY digits are possible when writing something in a field... i.e. only 0,1,2,3,4,5,6,7,8,9,10,.....

 

However, I thought the function below did that, but only to a certain point... if I write only letters then I will get false, which is ok.. but if I write digits first and then letters, 55aabb, then I get true...

 

Do you see my problem? I only want it to allow digits, nothing else:

 

 

public function validatePhone($validate)

{

$goodChars = "^[0-9]";

 

if( ereg("$goodChars",$validate) )

{

 

// if there are less than 8 digits, then its not correct.

if( strlen($validate) < 8 )

{

return false;

}

else

{

return true;

}

 

}

else

{

return false;

}

 

}

 

PS! I also have the same problem when I only want to allow letters in another function .. So please help me, AGAIN :-) Thanx in advance

The expression ^[0-9] must match at least one digit at the beginning of the string to be valid. To extend this to the entire string use ^[0-9]+$. Moreover, see ctype_digit.
