Refinement of Wordpress

Display the user ID of the person who created the advertisement in the email to the admin; add a function so that the email addresses include Dear Madam/Sir (in some addresses it is correctly set, in others it is not); on the user page in the admin panel, add a "date" field for manual date selection and include a function so that on this date the user is automatically deleted. Add a column to the user inquiries page in the admin panel, where checkboxes can be marked, with a checkbox at the top to select all at once, and a button to delete selected. The email about the end of the publication period of the advertisement is duplicated, needs correction.

The registration confirmation link and the tariff change link should be one-time use. When clicking this link again, a message should appear indicating that the confirmation has already been made. Hide the button that redirects to another page for customers (it should remain accessible for performers). In the admin panel, the date and time of the request to confirm the tariff change are displayed, but for some reason, the correct time is set, but the date is wrong (exactly one week ahead, so if today is 26.05, it shows 02.06).

The advertisement title should not be editable by the user; format the display of the photo associated with the advertisement; implement validation for symbols provided in the advertisement and its title; on the advertisements page in the admin panel, display and allow filtering by the status in which the advertisement was published (publish, pending, draft).

Edit the table on the user account's invoices page. Automatically generated invoices display correctly, but if a document is added manually, it overwrites an existing document and the previous one disappears. Create a delay for publishing the advertisement if it was automatically moderated (the delay for sending the email about the publication has already been created, but it needs to be linked to the actual publication itself).

Currently, invoices are stored in the admin panel. In the admin panel on the invoice pages, create a button that, when clicked, makes the selected invoices disappear from the admin panel on all pages and exports them to another location/application.

When changing the status next to the document associated with an invoice, the status should change simultaneously for both the invoice and the document. If the status of the invoice is changed, the same status should be set for the document; display the reminder date in the generated PDF and email text; when deleting a document on one admin page, it should be deleted everywhere where it is stored.

Create a checkbox, and if it is checked, emails and invoices/documents are sent/uploaded as currently configured. If the checkbox is unchecked (not checked), invoices/documents should be created and saved in the admin panel but not uploaded to the user cabinet and no emails about new invoices should be sent, effectively blocking the invoice sending function. To unblock the invoice/email sending function, create a button with a month selection for the invoice/document, which, when clicked, will upload the invoices/documents to users and send emails about the new invoice.

Hide user data everywhere it might be accessible to third parties (discuss the best way to do this).
