Check if you don't reassign $name variable: 

$name = $_POST['name'];
UPDATE g SET name='$name'

change variable name and try to pass it to db: 

 $name_new = $_POST['name'];
UPDATE g SET name='$name_new'

when you are not inserting something in db while other tables insert the biggest possible scenario is that you are not passing anything, the other scenario is that your db 'name' table is not assigned for string, for example if you changed name of 'id' table to 'name', it will not save string. Try passing to db custom 'name' not from variable, like 

"UPDATE g SET name='somewords'

if it saved, then problem is in your variable, if it does not save and others save, then it is your table conf
