  • apply_input_filter_rules

    Submitted by jgordon on June 19, 2009 - 4:30pm

    Purpose: To auto set and hide drupal input format settings. The input format settings don't always makes sense to the uninitiated and so it's often nice to just set them and forget them for certain users. This function helps accomplish that, although it'll need to be customized for every unique situation.

    Description: Recursively finds specified input format fields in a drupal forms API array and auto sets them depending on configured rules. The rules are configured inside the function. It would be better to pull these rules out to make the function generic, but this is good enough for me for now. If someone else uses this function I'll probably make it more generic.

  • override_submit_buttons

    Submitted by jgordon on June 19, 2009 - 4:36pm

    Purpose: Overrides drupal forms API submit buttons. Creates nice, rounded corner submit buttons using a hacky table tag. Sprinkle in imagery and css as necessary. It relies on a theme function called 'blank_image' that just renders a 1px X 1px transparent gif used to fill space so that the thing will work right in IE6.

    Description: This is a recursive funtion which searches through all the child elements of the current element. When it finds an element determined to be a button, it appends a link button at the end of the button. The link button will call the button's click() function on click. Therefore, it essentially replaces the button. We send down both the input form element and the link button so that we can degrade gracefully if the user doesn't have javascript.
