Thank you, but I had found this code 'unset' before you wrote here, but the problem is I do not know how to use it. So for example this is a simple code:
Code: Select all
<input type="text" name="abc" />
<input type="submit" />
After first submittion echo shows my answer I wrote into text field, but after refreshing/reload page it should be empty or unknow, should not be? So this is that problem ... nothing happen, eho shows same value... you know why?
