form_api: same form called multiple times, wrong form_state values
by Hans Langouche 15 Mar '10

15 Mar '10

Hi all, I have a small admin form (2 buttons and a hidden value) that is repeated multiple times (each time the value is different). Now whenever I access $form_state['values'] from the submit function, the hidden value always returns the data from the first form. When I print out $_POST directly I do get the correct data. I've been searching this and it seems this is because the form_state is cached. I couldn't find any workaround though, so for the moment working with $_POST. Anyone know the correct way to do this ? Tnx, HnLn

Re: [development] URL encoding

Hi, I am not creating the URL, but I parse the URL from XML content and I want to urlencode it. Also, I am looking to preserve all the reserved characters in the URL and not just '?' or '&'. -- Regards, Nitin Kumar Gupta http://publicmind.in/blog/ On Thu, Mar 11, 2010 at 6:59 PM, Don <donald(a)fane.com> wrote: > If you use l() or url() the query section is passed separately, so the '?' > and '&' are preserved.

URL encoding
by nitin gupta 11 Mar '10

11 Mar '10

Hi, I am trying to convert a URL to its encoded equivalent. i.e. http://example.com/path with spaces/ to http://example.com/path%20with%20spaces/. The problem I am facing is that rawurlencode or urlencode, encodes all the characters and does not show mercy upon the reserved characters such as '?', '#', '=' which makes the URL invalid after encoding. I understand that this behavior of these functions is expected considering the fact that they are to be used to encode data (such as query) that can be appended in an URL, but it isn't helping the current situation. I thought of the following procedure to achieve the above: 1. run rawurldecode on the input url, so that we do not accidentally encode twice if whole or part of URL is already encoded. 2. then run rawurlencode, and then preg replace these reserved characters. Though it works, I am not sure if it is the correct way to handle this. Any help through ideas or code will be highly appreciated as this will be useful in Feeds Image Grabber <http://drupal.org/project/feeds_imagegrabber> and Facebook-style Links <http:///drupal.org/project/facebook_link> module. Also, off the subject: shouldn't drupal_http_request() should take care of such encoding? -- Regards, Nitin Kumar Gupta http://publicmind.in/blog/

Calendar views filter issue
by Karyn Cassio 10 Mar '10

10 Mar '10

Happy Monday to all, I have an issue that has been plaguing me for a few days now. I am using calendar view, but instead of showing the month in the calendar grid, I am listing the events for the month out. This works fine, and the date browser Prev, Month, Next, works perfectly. However, I also want my visitors to be able to filter the events by month and/or event type. For this I have exposed filters to allow this. However, in the preview, the filters will not effect the output at all. I click an event type, and all event types are returned to me. Select a different month, and all events for the current month are returned. However, if I copy the derived query to mysql and run it, the results I expected are returned. Any thoughts as to why I'm not getting the filters to properly effect the output on either the web page or the preview? Thank you for any thoughts you may have, -- Karyn Cassio Drupal Developer

Altering the delete process of a node
by Ramon Vilar Gavaldà 09 Mar '10

09 Mar '10

Hi I want to alter the delete process of a node to add a new precondition. For example, I want to prevent the deletion of a document node if there are some categories (another content type not the Drupal category of the Taxonomy core module) associated with it. It's possible to add this precondition? Both content types are CCK related. Thanks in advance Ramon -- Ramon Vilar Gavaldà - http://ramonvilar.facil.cat - http://blog.facilitant.net Membre de FÀCIL - http://www.facil.cat Membre de l'esplai SESA - http://www.esplaisesa.org

How is it that new Drupal user is given CVS access to ban countries
by Victor Kane 09 Mar '10

09 Mar '10

Regarding the _rigorous_ CVS rights granting process, how is it that new user http://drupal.org/user/701600 is rushed through that process, and allowed to infect the Drupal codespace with a module banning countries from using a Drupal site??? The offending module: http://drupal.org/project/countryban goes against all democratic sentiment and should be taken down immediately, and this individual, who wishes to do the work of those who would restrict internet access based on origin of country, should have his CVS rights taken from him immediately.

AJAX Login as Horizontal
by CK-Bushidodeep 09 Mar '10

09 Mar '10

Hi, Fond of the Ajax Login module<http://drupal.org/project/ajax_register> It displays vertical and could use some insight on displaying horizontal. Should it be customized in the page.tpl.php or with jQuery. It's hoped someone has a snippet for this. As I'm sure this has been done before. ___________________________ CK

Form API and enter key press
by Pierre Rineau. 09 Mar '10

09 Mar '10

Hi all! I experience a simple problem, which a lot of people must have experienced too. I have a lot of forms with multiple submit actions, my problem here is when a user press the enter key, it does submit the form, but using the first found action (in form API elements order). My problem here is because a multistep form ergonomic style would tell you to put <prev action> then <next action>, but when pressing enter, the <prev action> is the first submit button found so the browser will submit this one. I experience the same problem in other use case than multistep form. Is there a clean way (without too many JS) to force the default submit action on enter key press? Regards, -- Pierre (pounard) R.

Help needed to convert a module to D7 with AJAX in forms
by Tobias Quathamer 07 Mar '10

07 Mar '10

Hi all, I've run into a problem with D7 and AJAX-enabled forms. What I try to do is to have a selection list use options depending on another selection list. I've looked at the code of the AJAX examples module, but I could not find why my code is not working. A part of my code follows, the complete code can be found here (lines 356 onwards): <http://drupalcode.org/viewvc/drupal/contributions/modules/weather/weather.f…> I've separated those function calls into their own file, they are not in the main .module file. Could this be a cause of problems? I would appreciate any hints or pointers. Regards, Tobias function weather_location_settings_form($form, &$form_state, $display_type, $display_number, $location_id=NULL) { $mode = 'edit'; // Handle the addition of a new location. if ($location_id == 'add') { $mode = 'add'; $location_id = NULL; } // If the location exists, get the settings. If it does not exist, // get the default location settings. $settings = weather_get_location_settings($location_id); $settings->places = weather_get_places($settings->country); $form['country'] = array( '#type' => 'select', '#title' => t('Country'), '#description' => t('Select a country to narrow down your search.'), '#default_value' => $settings->country, '#options' => drupal_map_assoc(weather_get_countries()), '#ajax' => array( 'callback' => 'weather_location_settings_form_callback', 'wrapper' => 'weather_place_replace', ), ); $form['place'] = array( '#type' => 'select', '#title' => t('Place'), '#description' => t('Select a place in that country for the weather display.'), '#default_value' => $settings->icao, '#options' => $settings->places, '#prefix' => '<div id="weather_place_replace">', '#suffix' => '</div>', ); $form['submit'] = array( '#type' => 'submit', '#value' => t('Save'), ); // Do not show the 'delete' button if not in 'edit' mode. if ($mode == 'edit') { $form['delete'] = array( '#type' => 'submit', '#value' => t('Delete'), '#submit' => array('weather_location_delete_submit'), ); } return $form; } function weather_location_settings_form_callback($form, $form_state) { return $form['place']; } -- Tobias Quathamer | Quidquid latine dictum sit, altum viditur.

CCK Checkbox Matrix module?
by Robin Clarke 06 Mar '10

06 Mar '10

Hi, I was wondering if anyone knew of a CCK module that could make a field give a matrix of checkboxes. I have attempted to create a mock of what I am looking for here http://www.haletechnology.co.uk/cck_matrix_checkboxes.html The Matrix module <http://drupal.org/project/matrix> would be great, except the matrix is made up of text input fields, instead of checkboxes. Any suggestions would be appreciated. Thanks robin
