Repairing loose under drawer slider in an old dresser

Susan
by Susan
I recently purchased a 6 drawer used dresser. One end of several of the under drawer sliders is not attached to the drawer, plus one slider has a crack running lengthwise down a portion of it. The end of an additional slider has been re-tacked to the drawer with a short screw.
What is the best and easiest way to re-tack the loose sliders end to the drawer bottoms? How do I repair the split slider? Sliders are all lightweight wood. Thank you.
Center slider, partially attached to drawer bottom - lower end of slider has a small staple to affix it to the drawer, but it’s not holding slider in place any longer due to age.
