Zend Soap Client exception

If Zend_Soap_Client is giving you an "Invalid SOAP request" and you don't know why, try adding "$client->setSoapVersion(SOAP_1_1);".

The error I was getting:

[SoapFault]

Drupal and php snippets

useful link: http://drupal.org/handbook/customization/php-snippets

to get php in blocks, enable the Php Filter in the modules section.

I've managed to break a site (so that nothing renders because of a php error in a block) and fix it by posting a page that I already had open with that block being edited.

I haven't had to work out how to perform such a fix without that lucky open page (yet).

Drupal, Zen, Nice Menus

If you're using trying to use Nice Menus to make a Zen subtheme for Drupal, you might need to remove the "overflow: hidden" from the navbar block in layout.css if you're having trouble with your menus not working or only partly showing up.

Here's a quote from layout.css (the comment is not mine):

  #navbar
  {
    overflow: hidden; 
      /* May need to be removed if using 
           a dynamic drop-down menu */
  }

Fragments of CSS

a:hover {color: green; text-shadow: #FF0000 1px 1px 3px}

Adding navigation links to drupal

The menu item I was looking for is Home � Administer � Site building � Menus >Primary links

Opera Mobile 9.5 Tab Limit

Opera on my mobile limits me to two tabs.

The trick to fix this is go to opera:config and search for 'tab'. Then change the value, save and restart.
