How can I change the output of a field in a View based on a conditional PHP statement? For example,

  if ($field_contents == "red") {
    $field_output == "This field is red";
  }
  else {
    $field_output == "This field is not red";
  }

I'm sure I've seen this before, but I can't work out how to do it now.

You can do this via theming, or preprocess.

Theming is easy:
Choose a template suggestion which fits to your needs, and there write this php. And do a print at the end.

I guess you should replace $field_output with $output.

Thanks! Ended up writing a new theme_views_view_field() function: in case anyone else stumbles upon this, it looked like this:

function mytheme_views_view_field($view, $field, $row) {
  if ($field->field == 'type' && $row->node_type == 'mynodetype') {
    return $row->node_title;
  }
  else {
  return $field->advanced_render($row);
  }
}

This means that whenever a view displays a node type field for a node with type 'mynodetype', it will display the title of that node rather than its type.

Fine. Do you want to write documentation about how to theme it?

Sure, seems like a good way to give something back to the community. Where should I put the documentation? Is there any style guide to follow?

There are many ways:
1. write a blog entry
2. write a d.o handbook
3. Write a description in the help of views. See the folder /help in views. Add a file with the documentation, and upload it here. Then i would create a patch for you, if you don't want to do it yourself.

I've had a look through views/help and there doesn't seem to be a natural place for this piece of documentation; similarly, it's just a standard intercept and override once you know what function you're after and that Views doesn't let you do this sort of thing in the UI, so a d.o handbook doesn't seem quite right.

I've written a blog post, though, which assumes minimal knowledge of themeable functions:

If anyone wants to take anything from there and use it in a handbook or in the official Views help then that's cool with me.
