Common household chores may include:

  1. Doing the laundry (washing, drying, and folding clothes)
  2. Dishes (washing and drying dishes, putting them away)
  3. Cleaning (sweeping, dusting, vacuuming, mopping)
  4. Garbage (taking out the trash, recycling)
  5. Grocery shopping and meal prep
  6. Lawn care (mowing the lawn, raking leaves, watering plants)
  7. Paying bills and managing finances
  8. Organizing and decluttering
  9. Taking care of pets (feeding, grooming, walking)
  10. Changing bed linens and making beds
  11. Doing minor repairs around the house (fixing a leaky faucet, replacing a lightbulb)
  12. Car maintenance (filling up gas, getting oil changes)

Using the list above, create a schedule with checkboxes, 12 columns and 31 rows, using the same text as in the bullet points list above. To turn this into a WordPress plugin, you can wrap the HTML code in a PHP function and use the add_shortcode function to register the shortcode.

Here is a PHP and HTML solution for a reward schedule where a user can check a box for each passing day, starting with January 1 and continuing to January 31. When all boxes are checked, another table is shown with February 1, and so on for three months.

First, we can create a PHP function that generates the HTML for the reward schedule table for a given month. This function will take two arguments: the number of days in the month and an array of booleans that indicate which days have been checked.

Then, we can use this function to generate the HTML for the reward schedule for January, February, and March. We can store the checked days in separate arrays for each month.

Then, we can use JavaScript to show and hide the tables based on whether all of the boxes are checked in the previous month’s table. We can use the onchange event of the checkboxes to check if all of the boxes are checked, and if they are, we can show the next month’s table.

With this code, your plugin will count the number of words in all published posts and display the total number of words and the average number of words per post on the plugin’s settings page.
