Title: Dropdown value plus two references Last modified: June 14, 2022 --- # Dropdown value plus two references * [den1sa](https://wordpress.org/support/users/den1sa/) * (@den1sa) * [3 years, 11 months ago](https://wordpress.org/support/topic/dropdown-value-plus-two-references/) * Hi, * I am trying to create a clothing size dropdown that will provide conversion sizes for UK, EU and US and upon a selection will add a value set for each option. * So for example, * Value —– UK — EU — US 4 ——- 4 — 34 — 37 5 ——- 5 — 36 — 39 6 ——- 6 — 38 — 41 * So if say a user is from the UK and is a UK size 5, the dropdown list shows the equivalent to the same in EU(36) and US(39), the value stored in the database is 5. * This is handy to provide the conversion for users in the EU and US without a separate conversion table. * Can anyone show me how this may be achieved. * Thanks, * Denis Viewing 7 replies - 1 through 7 (of 7 total) * Plugin Support [Aswin Giri](https://wordpress.org/support/users/aswingiri/) * (@aswingiri) * [3 years, 11 months ago](https://wordpress.org/support/topic/dropdown-value-plus-two-references/#post-15738372) * Hello [@den1sa](https://wordpress.org/support/users/den1sa/) * To achieve your requirement you will need an “IP to Location” service or You will need a field where users will select their country. * Secondly, you will need to make modifications to choices within the “Choice Callback” function based on the user’s country. Please [check this documentation ](https://docs.ultimatemember.com/article/1486-how-to-use-choices-callback) about UM dropdown Choices Callback. * Thread Starter [den1sa](https://wordpress.org/support/users/den1sa/) * (@den1sa) * [3 years, 11 months ago](https://wordpress.org/support/topic/dropdown-value-plus-two-references/#post-15739007) * Hi Aswin, * I think i didn’t explain myself very well, sorry about that. * If i provide another example thats doesn´t relate to country, i think it will be better to understand what I am asking for. * If a user clicks on the dropdown list they are presented with the following; * A value which is stored in the database and a description which is for reference only. * Value = 8 Reference = Small * so i need it to look like this … * 8 – Small 10 – Small 12 – Medium 14 – Medium 16 – Large … and so on. * So when I search for clothing size, I can filter clothing size that is between 8 and 10 only for example which is why i only need the value stored. * I hope this helps to understand my requirement. * Thanks, * Denis - This reply was modified 3 years, 11 months ago by [den1sa](https://wordpress.org/support/users/den1sa/). * Plugin Support [Ultimate Member Support](https://wordpress.org/support/users/ultimatemembersupport/) * (@ultimatemembersupport) * [3 years, 11 months ago](https://wordpress.org/support/topic/dropdown-value-plus-two-references/#post-15745466) * Hi [@den1sa](https://wordpress.org/support/users/den1sa/) * Have you tried using the Choices Callback function so you can separate the Labels and Values? Here’s an example code snippet: * ``` function my_cloething_size_list_dropdown() { $arr_sizes = array( "8"=>"Small", "10"=>"Small", "12"=>"Medium", "14"=>"Medium", "16"=>"Large", ); return $arr_sizes; } ``` * Regards, * Thread Starter [den1sa](https://wordpress.org/support/users/den1sa/) * (@den1sa) * [3 years, 11 months ago](https://wordpress.org/support/topic/dropdown-value-plus-two-references/#post-15747749) * Hi. * Thank you for your suggestion. I am not sure I understand this. I am trying to avoid having to use a table and list the corresponding description per line. So the user sees a dropdown that looks like this. * 8 – Small 10 – Small 12 – Medium 14 – Medium 16 – Large * and so on… * So i need both values to show up in the dropdown, but only the numerical value stored. * Does what you suggested achieve this? If not, is this doable? * Thanks in advance. * Denis - This reply was modified 3 years, 11 months ago by [den1sa](https://wordpress.org/support/users/den1sa/). * Thread Starter [den1sa](https://wordpress.org/support/users/den1sa/) * (@den1sa) * [3 years, 11 months ago](https://wordpress.org/support/topic/dropdown-value-plus-two-references/#post-15757539) * Bump.

It will display the size and text as option labels but stores only the size number to the database: * ``` function my_cloething_size_list_dropdown() { $arr_sizes = array( "8"=> "8 - Small", "10"=>"10 - Small", "12"=>"12 - Medium", "14"=>"14 - Medium", "16"=>"16 - Large", ); return $arr_sizes; } ``` * Please see the steps here to add the choices callback function: [https://docs.ultimatemember.com/article/1486-how-to-use-choices-callback](https://docs.ultimatemember.com/article/1486-how-to-use-choices-callback) * Thread Starter [den1sa](https://wordpress.org/support/users/den1sa/) * (@den1sa) * [3 years, 11 months ago](https://wordpress.org/support/topic/dropdown-value-plus-two-references/#post-15766569) * Thank you, i have now entered this in my code. * Can you please confirm that the value stored is stored as a number, so I can for example filter clothing size to only show between 12 – 16 only? - This reply was modified 3 years, 11 months ago by [den1sa](https://wordpress.org/support/users/den1sa/).
