php - Stuck on include() in a wordpress theme -

-

i'm going include() php file in wordpress theme file. file header.php, , function like:

<?php error_reporting(e_all); $filename = "path/to/file.php"; if (file_exists($filename)){ echo 'ok'; include($filename); } ?>

"ok" printed in resulting html, output stops after. used both relative , absolute path same result. missing home themes work?

file permissions ok.

edit: display_errors set off in wordpress. had enable find error , resolve. fatal.

$filename = "file.php"; // first of needs quoted  // $filename, not filename. missing $ before variable name  if (file_exists($filename)){   echo 'ok'; include($filename); }

(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...
