ajax - "lang" field disappears in JQuery post -

-

i had odd bug today, appeared in production version of software working on. i'm still scratching head trying understand happened.

i'm using jquery.post() send form data php script on server. 1 of fields in data called "lang". on development machine went fine, on production version, value in field disappear. debugged far call jquery post. in debugger see lang had value @ point, looking @ network trace shows lang field empty string.

the main difference between development , production version development use local non-minified copy of jquery, in production grab ajax.googleapis.com (currently using jquery 1.11.3).

after pulling out of hair, changed name of field "lng" instead, , started working correctly.

is known problem? post variables 1 needs avoid when using jquery?

partly i'm posting here save other poor souls having same issue.

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
