SJB Task: History of the listings, products and invoices must get saved and stay unalterable. If an employer changes or deletes his name or email adress or subaccount's email adress some sectors of this employer account may not be altered. If a product is bought or job has been posted by an email-address (!!no matter if main or sub-account), the email-address needs to be shown correctly on different pages. Once correctly shown, it must not be changed - even if the email-adress has been changed or deleted. This already has been realised for the invoice detail page regarding postal address and email-address for main account (these addresses are not beeing changed anymore). If invoice has been produced by subaccount, the process does not work (invoice detail page). Here, the email-address of the subaccount needs to be displayed and saved too. Following pages and email-templates are affected. On these pages, the email-address has to be added and must not be changed. * /my-products/ * Add listing: /add-listing/?listing_type_id=Job- * Add listing over Clone function: /clone-job/?listing_id=1014548 * my listings overview: /my-listings/Job/ * my invoices overview: /my-invoices/ * print-invoice/?sid=301&action=print * my invoice PDF detail * E-Mail templates 4x: (LE5) and (LE6) and (PE3) and (OE_14) Requirements: Experience with job boards ideal 5+ years of PHP experience (examples of work product) Able to respond to all requests for updates or work product within 12 hours We have additional projects and ideally would like to start a long term relationship requiring on average 10-30 hours per month.
