i have two file and two forms:
file 1:
<form name="name1" action="form2.php" method="post">
<input <? $_session['define'] = 'value1' ?> type="submit" ...>
</form>
<form name="name2" action="form2.php" method="post">
<input <? $_session['define'] = 'value2' ?> type="submit" ...>
</form>
As you see i have two forms and two different submit buttons but when i press each of them, the second value (the last) set to the $_session['define'] and in the second form i always have 'value2'.
