I need to let users to IMPORT an excel table from Front_End and display it (WPdatatable do import tables but only from Back-End) The users will import a table (only need to import 5 first columns to my web, then the web has to take the product links in the COLUMN#4 of each row and the parameters in the COLUMN#5, and fetch the next data when user clicks a button Import or Upload. \wpdatatables\templates\frontend\[login to view URL] – here I added the buttons –lines 25-41 Need to display this table in front-end: Table of those imported 5 columns + this next 8 columns more: \wpdatatables\assets\js\wpdatatables\[login to view URL] \wpdatatables\[login to view URL] – In this file I added code to fetch: Lines 53-54, lines 73-131 Column#6 -Seller (fetching from Ebay) \WooImporter\includes\api\ebay\[login to view URL] – lines 324-326 \WooImporter\includes\[login to view URL] – lines 73-95 and 250-280 Column#7 -Status (fetch from Ebay if it is not Vacation STATUS, in Ebay the vacation status appears when in the EBAY product page exist the tag "sm-mw", if is not on vacation then IF ShortMessage = "Invalid item ID." then : CALCULATE IF "EndTime" < today :ENDED (i mean if endtime data already passed away) ELSE : ACTIVE Column#8 -Quantity (easy to get from the installed plugin on the web) Column#9 -Price (easy to get from the installed plugin on the web) Column#10 -Delivery price (easy to get from the installed plugin on the web) Column#11 -Total price = Price + Delivery price) Column#12 -First extra charge (by default = Total price + Total price x 25/100) Column#13 -Second extra charge (by default = Total price + Total price x 50/100) When I click on the icons XLS or CSV, it has to export the table with a second worksheet of excel of 9 columns: (The plugin wpDataTable already exports the table, but only with 1 worksheet) Column#1 -sku(the values of the rows below the title have to be equal to the values of the column#1 of the first worksheet) Column#1 -Pid -column#3 -column#4 column#5 -first extracharge (the values of the rows below the title have to be equal to the values of the column "First extra charge" of the first worksheet) column#6 -second extra charge (the values of the rows below the title have to be equal to the values of the column Second extra charge" of the first worksheet) -column#7 column#8 -quantity (the values of the rows below the title have to be equal to the values of the column "Quantity" of the first worksheet) column#9 -letter-a (empty or the value has to be the letter "a" when the Status in the first worksheet is "ACTIVE") If the STATUS is not "ACTIVE" then make the: quantity=0, price, shiping price, and total price = empty cells. If the user uploads a SKU number equal to an SKU already uploaded by this user, then dont process those repeated rows and show a message or log to the user with those repeated SKU numbers. Create the condition of limit of rows to process per level of membership -500 rows for free level - 500 rows for bronze level -2000 for silver -5000 for golden I will provide the excel table template.
