Can I position all selected vertices to the same place?
I basically want to set all of their x positions to 0.

$\begingroup$ Not sure, it's more a question about how to position several vertices at a (same) given position (not just align on an axis). Am I right, @Petah? $\endgroup$– PolossonJan 12, 2014 at 11:05

$\begingroup$ @Polosson I believe the OP was asking how to align vertices on the X axis. "I basically want to set all of their x positions to 0". $\endgroup$– gandalf3 ♦Jan 12, 2014 at 18:38

Just found an answer from: http://blenderartists.org/forum/showthread.php?167457-Transform-multiple-vertices-flatten-snap-to
There are two methods that I usually use
select the vertices and press S Z 0 to put all the vertices in the same z-position, then move then set the 'Median Z' value in the transform properties.
put the cursor in the wanted z-position, select the wanted vertices and set pivot to 3d cursor, then press S Z 0

$\begingroup$ first method is less destructive, does not have secondary effects. second method changes pivot point. $\endgroup$ Mar 19, 2022 at 19:58

In Edit Mode select the vertices and use scaling S, X to constrain it to the x-axis, after that you can numerically input the scaling value (in your case zero) 0, confirm with enter or LMB

Or programmatically:
import bpy, bmesh
me = bpy.context.object.data
bm = bmesh.from_edit_mesh(me)
for v in bm.verts:
if v.select:
v.co.x = 0
bmesh.update_edit_mesh(me, True, False)
