[php-db]global variables

hi all, i have prob with passing the values filled in a form. like <form action="action.php" method=post(get)> name: <input name="name".....> </form> so this form accepts data and gives it action.php here $name. my action.php is <?echo $name;?> but this nothing since nothing is passed.but <?echo $_get['name'];?> does print the name the sme thing is with post. i use apache 1.3.24 and php 4.2 .with postgres 7.2. now my ques is 1.are these variables stored as global variables in array _get[]. 2.but in tuts of many sites i've seen that <? echo $name;?> works.never i've seen this $_get['name'] .is this a prob arising because of some settings or is this a prob/feature of php4.2.how can fix it so as to make it work with $name 3.also now if i write $query="insert into table values($_get['name'])"; pg_query($connection,$query); i get a strange error saying some strange stuff.doesn't this work. plz help me fix it bye suman _________________________________________________________ Click below to visit monsterindia.com and review jobs in India or Abroad http://monsterindia.rediff.com/jobs
