Attach WYSIWYG to custom Drupal form -

-

i have custom module implementing system settings form, , attach wysiwyg text area field. however, nothing doing having affect. using latest wysiwyg module ckeditor. there no js errors. on screen plain text area.

code:

$form['mymodule'] = array(             '#type' => 'fieldset',             '#title' => t('settings'),         );      $form['mymodule']['email_content'] = array(         '#title' => 'email content',         '#type' => 'textarea',         '#description' => t('the content of message emailed user when license key assigned. can use [user_fullname] , [user_license_key] substitute user name , license key, respectively.'),         '#default_value' => variable_get('mymodule_email_content', ''),     );      $form['mymodule']['format'] = filter_form(2);

all seems provide filter selection. got page: http://drupal.org/node/358316. when pick format, wysiwyg not load.

what want have form present wysiwyg without having make format selection. how can trigger load on textarea in form api?

you need add subarray wysiwyg thing

    $form['mymodule']['foo']['email_content'] = array(         '#title' => 'email content',     . . .

    $form['mymodule']['foo']['format'] = filter_form(2);

maybe can hide filter selection box using css?

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
