problem with drupal_goto
by Lluís 17 Mar '10

17 Mar '10

I have some custom nodes and I need some blocks to appear depending on node-type. My approach to solve the problem was replicate "/node/$nid" behavior to "/my-type1/$nid" in order to make blocks visible depending on node-type. If a user entered a view to "/node/$nid" he got "drupal_goto" to the right url. My problem now is that for some node-types /type/$nid works, but /node/$nid stopped working; any hint? I am completely lost right now. == hook_nodeapi == ..... case 'view': if ((arg(0)=='node')&&(arg(1)==$node->nid)) { switch ($node->type) { case 'my-type1': case 'my-type2': drupal_goto($node->type.substr($_GET['q'],4)); break; ..... == hook_menu == ...... foreach($node_types AS $key) { $items[$key.'/%node'] = array( 'title callback' => 'node_page_title', 'title arguments' => array(1), 'page callback' => 'node_page_view', 'page arguments' => array(1), 'access callback' => 'node_access', 'access arguments' => array('view', 1), 'file' => 'node.module', 'file path' => drupal_get_path('module', 'node'), 'type' => MENU_CALLBACK, ); $items[$key.'/%node/view'] = array( 'title' => 'View', 'type' => MENU_DEFAULT_LOCAL_TASK, 'weight' => -10); ...... -- *Les normes hi són perquè hi pensis abans de saltar-te-les *La vida és com una taronja, què esperes a exprimir-la? *Si creus que l'educació és cara, prova la ignorància. *La vida és com una moneda, la pots gastar en el que vulguis però només una vegada. *Abans d'imprimir aquest missatge, pensa en el medi ambient.

Force admin login
by Tomáš Fülöpp (vacilando.org) 04 Mar '10

04 Mar '10

Hi, Is there a backdoor way to force admin login if everything fails? Something like the way $update_free_access is changed to TRUE to allow running update.php....? A client got locked out of D6.15 completely, including admin. Login seems to work (I see admin only links on logon), cookies are set, but only on the initial page.... any subsequent click is treated as done by an anonymous user (checked the watchdog this way). I've cleared all browser caches, Drupal caches via the db, also the Drupal sessions table, checked the cookie domain, the admin user record exists in the user table, etc. in settings.php, deleted and re-uploaded D6.15. Nothing in the php logs. Nothing unusual in watchdog - just access denied by anonymous... Spent an equivalent of a day on this but I know there is a ton of things I can still try - e.g. rebuild access rights. But I do need to log in first, only by myself. So... is there a way to force admin login? Cannot find this info anywhere. Thanks! Tomáš

How to add user role during registration with custom form
by Steve Edwards 27 Feb '10

27 Feb '10

I took over a site that uses a custom registration form that directly calls user_register_submit directly, and I need to have a user role added to this user when this form is submitted. However, I can't add the value to $form_state['values']['roles'] because the function errors out if there is a roles array because it is seen as a 'malicious attempt to alter protected user fields.' Since that function then calls user_save, it seems that once the user is saved, I need to 1) load the user I just created, 2) add the role to the object, and 3) save it again. However, in order to call user_load, I need the uid, which isn't returned from user_register_submit. The only logical thing I can think to do is query the users table with the user name I just created (entered as part of the form), get the rid, and then call user_load and do my thing. Is there a better (and easier) way to do this that I'm missing, or am I on the right track? Thanks. Steve

Publishing data from legacy svn repository
by Stephane Corlosquet 24 Feb '10

24 Feb '10

Hi, I'm working on a project where I need to publish data stored in svn, so instead of coming from the Drupal database, the node body would come from checked out (read only) files on the server (it could be any VCS for that matter). Each file would be associated with a node (automatically or manually), or could be displayed via a different mechanism altogether using an appropriate loader. There is plenty of information on using svn for development, staging or deployment purposes, but I could not find anything on the topic I'm interested in here. Has anyone worked with such workflow and care to share either code or the lessons they learnt? Steph.

Form API and Javascript stuck
by Karyn Cassio 22 Feb '10

22 Feb '10

Hi Everyone, I hope you are enjoying your weekend and not working too hard. I'm still trying to get my head around js, and was hoping someone may have some insights to help me with the next steps on a form I am creating. I have an order form that is going to be dynamically created. I am able to successfully pass the quantity value upon user input for field 1. Basically I'm using onchange() to pass the quantity value to the script. The id of the price field is of the format unit-price-0, unit-price-1, etc. Each line item's subtotal should update before going onto the next line item. Here's the js function. Each line item has its own unit-cost, quantity, and subtotal. Any help would be so appreciated. One suggestion was to "have form api write those hidden fields after each element is created" Not sure how to accomplish that. function calcPrice() { // Get the Quantity From Form Field // unitCost = document.getElementById ('edit-price-0').value; theQty = document.getElementById ('edit-quantity').value; subOrderCost = theQty * unitCost; //Line Item Cost // subtotalCost = subOrderCost; // subtotalCostDisplay = addCommas(subtotalCost.toFixed(2)); // subtotalCostValue = subtotalCost.toFixed(2); // //// Display Cost To User // document.getElementById('edit-subtotal').value = "$" + subtotalCostDisplay; } -- Karyn

Custom registration process
by Stewart Birch 22 Feb '10

22 Feb '10

Hello to you all I'm needing to add quite a few fields to the registration process. Is the native login / registration process easy to amend or would you recommend using webform and building it from the bottom up so to speak. It's seems crazy not to use what's already there, but I cannot see a straightforward way to add to it. What have your experiences been? Many thanks Stewart -- http://www.flickr.com/people/mrbirch

No suitable nodes available at RackspaceCloud (Mosso)
by Tomáš Fülöpp (vacilando.org) 18 Feb '10

18 Feb '10

Hi, At RackspaceCloud (former Mosso) I've been plagued with a very unfortunate problem that i crippling both my work and the work of my clients -- namely the infamous error message "Unfortunately there were no suitable nodes available to serve this request." Those of you at RS Cloud must have bumped into it. It is cryptic and happens unpredictably. The cloud is very stable and scalable, but for any a little bit heavier Drupal installation people do start getting these errors. *Basically, it is a generic error thrown by load balanced systems that occurs as a result of a script exceeding a maximum timeout value (not the PHP timeout value!) If a client connection does not receive a response from the server after approximately 30 to 60 seconds the load balancer will close the connection and the client will immediately receive the error message. In most cases, the script will continue to execute until it reaches completion, throws an error, or times out on the server, but the client will not see the page load as expected and will instead receive this error.* I've used Boost for anonymous pages, Parallel, Memcache, etc., all of which helped and anonymous users *usually* don't get this error. The problem is with admin or any other a bit heavier work of logged in users. Even for basic Drupal websites with not too many modules! Pages like the list of modules, or the status page, i.e. heavy database or file requests, or API calls in PHP, are very likely to time out. Over the past year I've had a number of discussions with techs and admins at that cloud, but the situation is unresolved. They recognize the problem but maintain this is due to the special/unusual setup they use for their cloud. It is not a problem for some other CMS / frameworks. E.g. a very heavy MediaWiki installation runs just fine. Drupal seems to be less compatible with their system, somehow, somewhere. *Now, why do I mention all this in the development list? I've been intrigued by one little ray of hope in their words: "if a client connection does not receive a response from the server after approximately 30 to 60 seconds the load balancer will close the connection and the client will immediately receive the error message". Their techs said if I were able to emit any kind of intermediary response to the client during rendering of the page, then this would be solved. * Indeed, a bit like the Batch API works in Drupal (with that I often run night-long scripts without problems). I wonder, maybe this is a more generic problem for any system that employs load balancers? *So my questions to you, colleagues, is -- do you see any place in Drupal processing chain that could be used, and approximately how, to make sure that the load balancer keeps the connection opened.* If you have any ideas, wild or proven, I will be happy to test and develop them further and bring them back to the community, of course. If this succeeds, I think many of us will be relieved (and able to focus on development again!) Thank you for any ideas - on and off this list. Best regards, Tomáš / Vacilando
