Implementation of hook_requirements().

The translation template extractor requires the PHP token extension to be enabled. We should not let Drupal to install the module if this is not available. Also, if it was available, but the site was moved or PHP was changed, we should nag again: so we run in install and runtime as well.

File

./potx.install, line 16

Install requirements checking for the module.

Code

function potx_requirements($phase) {

    'value' => function_exists('token_get_all') ? $t('Available') : $t('Not available'),
  );
  if (!function_exists('token_get_all')) {
    $requirements['potx_tokenizer']['description'] = $t('The <a href="@tokenizer">PHP tokenizer functions</a> are required.', array(
      '@tokenizer' => 'http://php.net/tokenizer',
