Disable tinymce for fields in drupal module: webform
I normally disable tinymce for certain textareas by overriding the tinymce function theme_tinymce_theme. This allows me to target textareas by their name attribute. For example, to disable the editor for all cck fields that I have named 'description', and all the devel modules 'php code' block textareas, one would put the following in that function:
function phptemplate_tinymce_theme($init, $textarea_name, $theme_name, $is_running) {
switch ($textarea_name) {
// Disable tinymce for these textareas - using the field's name attribute
