Hello, I have this problem with PHP 5.3.1 (XAMPP Lite 1.7.3)

It appears when I push the button to create new values in a CCK field with unlimited possible values.
I think that it's again a problem with the ampersand, isn't it?

Any suggestions?

Thanks

I have a similar problem:

warning: Parameter 2 to taxonomy_treemenu_menu_link_alter() expected to be a reference, value given in C:\wamp\www\drupal-6.15\includes\common.inc on line 2829.

this repeats a lot when I make changes to content structure.

Cron does not appear to be working also.

Im using Drupal 6.15, php 5.3.0 and am building a site on wampserver.

Solutions would be greatly appreciated

I too have got this error

shambler commented 22 February 2010 at 10:27

I too have got this error when clicking on 'Add another item' on a field item with unlimited items. What's the solution?

I am running 6.15 and php 5.3.0 so I guess the php is the problem.

2827 foreach

shambler commented 22 February 2010 at 10:51

2827 foreach (module_implements($type .'_alter') as $module) {
2828 $function = $module .'_'. $type .'_alter';
2829 call_user_func_array($function, $args);
2830 }
2831 }

Is there a simple change we can make to line 2829?

Cannot upload due to this problem

cochranrg commented 22 February 2010 at 20:30

I am trying to use the core upload module to allow users to upload XLS files etc. But, every time I try to upload a file I get this error:

warning: Parameter 2 to date_form_alter() expected to be a reference, value given in ..\includes\common.inc on line 2829.

HELP!

Date

cochranrg commented 23 February 2010 at 18:16

I since removed the Date API and all other CCK date items from administration and this error has gone away. I am still having upload/download issues but they are not related to this.

Same problem here.

Problem solved

cesarkohl commented 2 March 2010 at 13:14

Again, it's teh ampersand.

All you need to do is to find the related function and delete two ampersands. I don't know why, but I saw a lot of pro ppl doing this and solving almost the same problem.

Example:

# warning: Parameter 2 to content_copy_form_alter() expected to be a reference, value given in C:\Arquivos de Programas\wamp\www\drupal-6.15\includes\common.inc on line 2829.

1. find where's content_copy_form_alter()
2. it's here! /cck/modules/content_copy/content_copy.module
3. open and find the function content_copy_form_alter(). It's like that:
function content_copy_form_alter(&$form, &$form_state, $form_id)
4. delete the two ampersands
function content_copy_form_alter($form, $form_state, $form_id)

And that's it!

ps: Look for the .module archive in the root of the related module folder.

Thanks for the reply. I have

I'm having the same error.
I just migrated my website to a new machine with Wamp.
It used to work perfectly with Xampp, but now I get similar messages all around and many functionalities are broken.
I don't think removing the ampersands is the solution. I'm getting Nulls and ´0´ where objects were expected.

Your hack saved me a major headache on a current project. This issue really needs to be addressed by someone working with Drupal.core and PHP 5.3. Us poor developers shouldn't have to go through this pain when creating websites.

would love to have a permanent fix to this issue

When clicking 'Add more' button, the problem origins in CCK

bitsgrecco commented 16 October 2010 at 15:59

When using the 'Add more' button, the problem origins in the way CCK calls 'common.inc#drupal_alter(...)' to fire notifications to hook_form_alter.
Both problem and solution are documented into 'common.inc#drupal_alter(...)', since function func_get_args (used to have flexible number of params for drupal_alter) always returns params by value. So, we can only receive a single by-ref param (&$data), but signature of 'hook_form_alter' takes 2 by-ref args!!!

See common.inc#drupal_alter(...)

Fix have to be aplied to file 'modules/cck/includes/content.node_form.inc'.
Calls to drupal_alter from CCK need to put $form_state's reference into $form_element['__drupal_alter_by_ref'] before being done, and without that empty array passed as empty param!

These are the diff changes:

[modules/cck/includes/content.node_form.inc]
325--- drupal_alter('form', $form_element, array(), 'content_add_more_js');
325+++ $form_element['__drupal_alter_by_ref'] = array(&$form_state);
326+++ drupal_alter('form', $form_element, 'content_add_more_js');

It works !
