Wordpress Development

The site was created on WordPress * Set up link personalization so that by clicking on a link sent from the site, the page opens only to the user to whom it was sent. If clicking on the link will enter the login information of another user, in this case it should not proceed. Configure the correct redirect to the necessary sites * insert a link to a document for download on one of the site pages (this document has already been generated and there is a download link on another page of the site) * Add generation of an invoice for using the site in pdf form (the form will be provided) with saving on the pages in the admin panel and on the user page. * Edit the account pages created in the admin panel, add a filter by user, month, account status and account number (these fields have been created, you just need to display them on the page). It should be possible to delete and download invoices, both individual documents and all at once. * There are 2 fields created on the site (tariff payment and number of contacts). You need to make sure that these fields are also displayed in the mobile version of the site and add statement generation for these fields. * Set up the generation of a report (pdf file, form will be provided), which displays information about which users did not pay the bills of the previous month * On the 1st day of each month, files must be generated in Excel and XML-Format with the bank data entered by the contractor during registration and the amount to be paid from the account. One file for all users (form will be provided). * Fix the code when sending an E-Mail to the user at the time of invoice generation. Now email is sent many times in a row per day, it should be 1 time * Add one more page to the artist registration form, where you will be able to select 4 tariffs. These blocks with tariffs should be disabled and adjusted from the admin panel For the selected tariff, pdf invoices should be generated (the form will be provided) with the calculation of the invoice amount depending on the day of the month when the tariff was selected. The created account must be saved in the admin panel and on the user page. At the time of invoice generation, an email should be sent to the admin with the invoice tab and to the user with a link to the invoices page in the personal account. If there were registrations with a choice of tariff, files should be generated in Excel and XML-Format with the bank data entered by the contractor during registration and the amount to be paid from this account. Subsequently, for already registered users, these accounts and files should be generated 5 days before the end of the month. If on some day there were no registrations on the site, then files and accounts should not be generated. * Improve the Newsletter plugin so that an email is sent every time you register/deregister. Create, without a plugin, a daily newsletter of advertisements to users according to the categories entered during registration, the last 10 advertisements at a certain time of day. It should be possible to enable/disable this newsletter from the admin panel * Create in the admin panel the ability to enable/disable automatic sending of invoices * Change the error text when entering incorrect login information on the site * Configure sending an email to the user after granting access to the site * Add a function for automatic publication of advertisements with a check for the presence of contact information in the advertisement. There should be an option to enable/disable this function in the admin panel. * Set a password on the accounts page in the admin panel and on the server on the database (folder) where the accounts are saved, so that no one except one admin (me) can view, delete or change accounts.
