php - Test if a cookie exist with it name in a variable -

-

i'd test if cookie exists, pretty basic, know, doesn't want work well. so, here pieces of code related:

<?php $quesid = the_id()."gcquestion"; if(isset($_cookie[$quesid])){   ... }

the test fails, when cookie's name match generated variable. weird part when try type variable name hand if(isset($_cookie["94gcquestion"])), works.

question : can use variable name $_cookie ?

assuming you're using wordpress,

the_id(): displays numeric id of current post. tag must within loop.

the_id() template function , print id, doesn't return it.

to return id, use get_the_id() instead.

<?php $quesid = get_the_id()."gcquestion"; if(isset($_cookie[$quesid])){   ... }

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
