New to PHP preg replace help.

[rjliquigan]

Hello all, new to the php scene.

I'm having problems writing capital letters into the database: For example when i input MerryChristmas it will write erryhristmas or Testing123 it would be esting123. Any help would be greatly appreciated thank you heres what it looks like write now:

 

$groupname=$_POST['groupname'];

$newgroupname = preg_replace('/[^a-z0-9]/', '', $groupname);

$check2 = mysql_query("SELECT groupname FROM groups WHERE groupname = '$newgroupname'")

or die(mysql_error());

$check3 = mysql_num_rows($check2);

If you want to allow both lower and uppercase you can use the i modifier to enable case insensitivity.

 

$newgroupname = preg_replace('/[^a-z0-9]/i', '', $groupname);
