Embed Drupal node form anywhere

Submitted by admin on Tue, 10/01/2012 - 13:24

Simple 1 line of code to embed a Drupal node form anywhere in your site although I would recommend doing it the Drupal way which is creating a custom module for this.

print drupal_render(node_add('NODE_TYPE'));

Where NODE_TYPE is your content type (machine name).

If the code above returns an error that says the function node_add() is undefined, add the following code before it.

if (!function_exists('node_add')) {
  module_load_include('inc', 'node', 'node.pages');
}

Display Drupal menu local task tab according to node content type

Submitted by admin on Sun, 08/01/2012 - 16:38

By default every node should have the menu tab (MENU LOCAL TASK) of View and Edit.

If your module wants to add its own tab but only restricted to content type of "foo", then use the following code snippet.

XYZ below is your page callback for the new custom tab. Basically it calls another function to validate user's permission but we manipulate it to check the node type (via access callback).

Homepage of RD.MY

After securing my Malaysia country-level domain name KT.MY, I felt that it would also be fun to create my very own URL shortener service since its relatively easy to do especially with Drupal.

Question

The sum of the primes below 10 is 2 + 3 + 5 + 7 = 17.

Find the sum of all the primes below two million.

Solution

$sum = 2;
for ($i = 2; $i < 2000000; $i++) {
  if ($i % 2 != 1) {
    continue;
  }
  $d = 3;
  $x = sqrt($i);
  while (($i % $d != 0) && $d < $x) {
    $d += 2;
  }
  if ((($i % $d == 0 && $i != $d) * 1) == 0) {
    $sum += $i;
  }
}
echo $sum;

Question

By listing the first six prime numbers: 2, 3, 5, 7, 11, and 13, we can see that the 6th prime is 13.

What is the 10001st prime number?

Solution

$last = 0;
$count = 0;
$max = 10001;
for ($i = 3; $count < $max - 1; $i++) {
  if ($i % 2 != 1) {
    continue;
  }
  $d = 3;
  $x = sqrt($i);
  while (($i % $d != 0) && $d < $x) {
    $d += 2;
  }
  if ((($i % $d == 0 && $i != $d) * 1) == 0) {
    $last = $i;
    $count++;
  }
}
echo $last;
