sql - Webform : how to count and live display results -

-

update (that 1 works)

<?php if (arg(0) == 'node' && is_numeric(arg(1))) {   $nid = arg(1);   $node = node_load($nid);   if ($node->type == 'webform') {     $count = db_result(db_query('select count(*) {webform_submissions} nid = %d', $nid));     $atelier_1 = "sources" ;     $sql = "select count(*) {webform_submitted_data} data \"".$atelier_1."\" ;";     $count_atel_1 = db_result(db_query($sql));   } } echo $sql; echo $count_atel_1; ?>  webform has been submitted <?php print $count ?> times.

we'd use webform our students should register on workshops.

the webform works great. we'd display live number of students register in on of workshops other should know if there remains possibilities of registration (each workshop can accept 20 students @ same time)

i'm trying that doesn't work ($atelier_1 = "sources" ;) name of 1 workshop :

<?php if (arg(0) == 'node' && is_numeric(arg(1))) {   $nid = arg(1);   $node = node_load($nid);   if ($node->type == 'webform') {     $count = db_result(db_query('select count(*) {webform_submissions} nid = %d', $nid));     $atelier_1 = "sources" ;     $count_atel_1 = db_result(db_query('select count(*) {webform_submitted_data} data %d', $atelier_1');   } }  echo $count_atel_1; ?>

any or suggestion welcome

the way can show live, creating ajax in drupal, or drupal behaviours, or javascript.

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...
