Custom Lists

I have created websites that do this.

First there is a plugin to do the CSV import to a custom table:

Second in a child theme I created custom page templates to display a search/query form and display the results, also an add entry form, you will probably also need delete and edit. I found that the CSV import plugin was an excellent tutorial on handling SQL plus handling the SUBMIT actions. Rather than page templates you could do it using shortcodes instead.

Hello Ross,

Thank you for your inputs. Let me re-enter my question with more clarity:

1. We need to build a two or three column list
2. Upload CSV option to build the list
3. A form to allow us to submit values to the list to keep it growing or add new values.
4. We do not want to show list anywhere, instead, we want to show search option so that the search should be performed only on the selected column(s) (AJAX based if possible) and show the results from all columns in a tabular form.
5. Insert custom code (AdSense) before/after search button (between search field and button)
6. Insert custom code (AdSense) before/after search results

Any expert inputs will be of great value.

Best Regards,
Syed H
