Yes 1 No 1 7 Replies to “Many-To-Many relationships” I’m close, but when I test the table I can delete items from the class table, but I cannot add. ERROR: Not all rows have been added Reply Hi Zack, Can you send me some screenshots? Please use the contactform if you prefer to send them in private. Thanks, Peter Reply I am also getting this same error, was there a solution to it? Reply Can you send me your table options the related tables Jeffrey? Please use the contactform to send it in private. Thanks, Peter Reply I am wanting 3 tables, Table A the parent of Table B and Table B the parent of Table C. It looks like I cant just have a relationship (1:n) on Table A ==> Table B and Table B ==> Table C. This only gives me access to Table A and B. I tried adding a relationship Table A ==> Table C, and that gives me access to tabs for Table B and Table C but it wont let you link Table B to Table C. What am I doing wrong. I have only one template for each table. Reply Hi Carl, The plugin supports only one hierarchy level on a page. If you want to manage multiple levels on one page, you can use dynamic hyperlinks to jump between different levels. Multi level supports is planned for Data Forms (not yet available). Not for the back-end and shortcode wpdadiehard. Does this answer your question? Peter Reply When I attempt to “Add New” child row in a many to many relationship, I get an insert error. The child row is created but the links between the two tables are not. Add existing does not get an error. See the PHP log entry below: family ==> member ==> details Table family has the parent record Table details has the child record the row fails to insert into table member The database is named directory…. not wp_testsite_db [02-Apr-2022 03:55:51 UTC] WordPress database error Table ‘wp_testsite_db.member’ doesn’t exist for query SHOW FULL COLUMNS FROM `member` made by do_action(‘directory_page_wpda_wpdp_1_1’), WP_Hook->do_action, WP_Hook->apply_filters, WPDataProjects\WPDP->manage_project_page, WPDataProjects\Parent_Child\WPDP_Parent_List_View->show, WPDataProjects\Parent_Child\WPDP_Parent_List_View- How can I fix this?
