Title: Change username using costume field Last modified: February 3, 2022 --- # Change username using costume field * Resolved [cimot456](https://wordpress.org/support/users/cimot456/) * (@cimot456) * [4 years, 2 months ago](https://wordpress.org/support/topic/change-username-using-costume-field/) * I created a registration form as below: * First name : Last name : Mobile number: City : Email : Password : * Because I didn’t include the username field, the username will be filled in by first name and last name without spaces (cmiiw). * So far everything is working fine. * ====== ### ====== * On the back end I’ve created a custom field with the following meta key: * 1. regno_agent 2. regno_cust 3. regno_partner * And this costume field will be filled in by the admin according to their respective roles after the customer has successfully registered/has been approved. * Example : * a. Michael > role > um_agent > regno_agent = a123 b. Samantha > role > customer > regno_cust = c456 c. Dorris > roles > um_partner > regno_partner = p789 * What I want to ask, how to make this custom field replace the existing username? * I got the reference to change the username as described below * Source: [https://wordpress.org/support/topic/change-username-after-registration-submit-hook/](https://wordpress.org/support/topic/change-username-after-registration-submit-hook/) * However I’m having trouble editing the code to be able to change the username dynamically. * Idea I have are as follows: * 1. Change the username using the custom field as in the above example if the field has been updated by admin * 2. As long as the costum field is not updated by admin, then leave it as is ( username remains first name and last name) * Thank you.

The roles and meta keys are correct. * 2. I saved the above code using the code snippet plugin. * 3. I did a test and signed up as a new customer. (name = michael antono and username field not shown on form this) * 4. On the admin page, I see a list of recent users > michael antono * Then I edited and updated the regno_agent > a123 field and changed the role to agent (default at registration is subscriber) * 5. After updating, the regno_agent field has saved data > a123. However, the username (user_login) is still the same/unchanged (firstname.lastname). * 6. I have also added regno agent fields etc on the profile form. As admin, I’m trying to change the regno agent (michael) field to a234. And the data has been saved, both on the profile page and in the back. ( a123 has been change to a234 for make sure updated is working) * 7. I have cleared cache (I am using wp super cache) * 8. I have also done UM User Cache at UM Dahsboard * And the username remains unchanged. * What have I done wrong? * Thank you * [missveronica](https://wordpress.org/support/users/missveronicatv/) * (@missveronicatv) * [4 years, 2 months ago](https://wordpress.org/support/topic/change-username-using-costume-field/#post-15329731) * [@cimot456](https://wordpress.org/support/users/cimot456/) * Thanks for a good description of you process. * I will change the code snippet so it’s updating the username (user_login) when you change the Role from subscriber to agent. * Thread Starter [cimot456](https://wordpress.org/support/users/cimot456/) * (@cimot456) * [4 years, 2 months ago](https://wordpress.org/support/topic/change-username-using-costume-field/#post-15329769) * Hi [@missveronicatv](https://wordpress.org/support/users/missveronicatv/) * Thank you for your effort * Hope you can achieve it * [missveronica](https://wordpress.org/support/users/missveronicatv/) * (@missveronicatv) * [4 years, 2 months ago](https://wordpress.org/support/topic/change-username-using-costume-field/#post-15329886) * [@cimot456](https://wordpress.org/support/users/cimot456/) * This code snippet will update username from a text field with meta values: ` regno_agent`, `regno_cust`, `regno_partner` * when you change role from `subscriber` role to an agent role: `um_agent`, `customer`,` um_partner` * ``` add_action( 'set_user_role', "um_020422_update_profile", 10, 3 ); function um_020422_update_profile( $user_id, $new_role, $old_roles ) { if( !empty( $old_roles ) && in_array( 'subscriber', $old_roles )) { if( !empty( $new_role ) && in_array( $new_role, array( "um_agent", "customer", "um_partner" ))) { if( current_user_can( "manage_options" ) ) { $new_login = ''; switch( $new_role ) { case "um_agent": $new_login = get_user_meta( $user_id, "regno_agent" ); break; case "customer": $new_login = get_user_meta( $user_id, "regno_cust" ); break; case "um_partner": $new_login = get_user_meta( $user_id, "regno_partner" ); break; } if( !empty( $new_login )) { wp_update_user( ['ID' => $user_id, 'user_login' => $new_login] ); delete_option( "um_cache_userdata_{$user_id}" ); } } } } } ``` * Thread Starter [cimot456](https://wordpress.org/support/users/cimot456/) * (@cimot456) * [4 years, 2 months ago](https://wordpress.org/support/topic/change-username-using-costume-field/#post-15329897) * Hi [@missveronicatv](https://wordpress.org/support/users/missveronicatv/) * I will try it now, * Thank You * Thread Starter [cimot456](https://wordpress.org/support/users/cimot456/) * (@cimot456) * [4 years, 2 months ago](https://wordpress.org/support/topic/change-username-using-costume-field/#post-15330051) * Hi [@missveronicatv](https://wordpress.org/support/users/missveronicatv/) * Still not working either. * Can you see this > [http://prnt.sc/26osequ](http://prnt.sc/26osequ) * The partner’s job is to offer products to potential customers by providing a referral code. * When a prospective customer registers (default as a subscriber), the prospective customer is asked to enter a referral code (owned by a partner) and it will be saved in the Subscriber ID field. * When this subscriber purchases a product, the admin will change the role to customer. * It’s the same when a subscriber wants to be a partner or agent. * And when that happens, I want the username to be changed to a unique code according to their respective roles. * On the front end, both partners and agents can simply share a link to offer a product through their profile page. (I have created a product tab on the profile page). * It looks like this : * site.com/regno/a123 * site.com/regno/p234 * Currently I use the user id as the permalink base profile. * But I’m afraid it will be unfair between the agent and partner because the permalink profile is easy to guess. (user id = 1, user id =2, …) * Previously I have also been looking for how to generate a unique user id (alpanumeric) but to no avail. * That’s why I created an additional field and want this code to replace the username so that potential customers don’t easily guess the permalink profile, whether it belongs to an agent or partner. * Any idea? * Thank you * Thread Starter [cimot456](https://wordpress.org/support/users/cimot456/) * (@cimot456) * [4 years, 2 months ago](https://wordpress.org/support/topic/change-username-using-costume-field/#post-15330067) * Hi [@missveronicatv](https://wordpress.org/support/users/missveronicatv/) * Revision / additional information: * Currently : * site.com/user/12 -> (user id) * Targets: * site.com/regno/a123 -> (username) * Thank you * [missveronica](https://wordpress.org/support/users/missveronicatv/) * (@missveronicatv) * [4 years, 2 months ago](https://wordpress.org/support/topic/change-username-using-costume-field/#post-15330255) * [@cimot456](https://wordpress.org/support/users/cimot456/) * I have updated one mistake in this code snippet: * ``` add_action( 'set_user_role', "um_020422_update_profile", 10, 3 ); function um_020422_update_profile( $user_id, $new_role, $old_roles ) { if( !empty( $old_roles ) && in_array( 'subscriber', $old_roles )) { if( !empty( $new_role ) && in_array( $new_role, array( "um_agent", "customer", "um_partner" ))) { if( current_user_can( "manage_options" ) ) { $new_login = ''; switch( $new_role ) { case "um_agent": $new_login = get_user_meta( $user_id, "regno_agent", true ); break; case "customer": $new_login = get_user_meta( $user_id, "regno_cust", true ); break; case "um_partner": $new_login = get_user_meta( $user_id, "regno_partner", true ); break; } if( !empty( $new_login )) { wp_update_user( ['ID' => $user_id, 'user_login' => $new_login] ); delete_option( "um_cache_userdata_{$user_id}" ); } } } } } ``` Viewing 15 replies - 1 through 15 (of 38 total) 1 [2](https://wordpress.org/support/topic/change-username-using-costume-field/page/2/?output_format=md) [3](https://wordpress.org/support/topic/change-username-using-costume-field/page/3/?output_format=md) [→](https://wordpress.org/support/topic/change-username-using-costume-field/page/2/?output_format=md) The topic ‘Change username using costume field’ is closed to new replies. * ![](https://ps.w.org/ultimate-member/assets/icon-256x256.png?rev=3160947) * [Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin](https://wordpress.org/plugins/ultimate-member/) * [Frequently Asked Questions](https://wordpress.org/plugins/ultimate-member/#faq) * [Support Threads](https://wordpress.org/support/plugin/ultimate-member/) * [Active Topics](https://wordpress.org/support/plugin/ultimate-member/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/ultimate-member/unresolved/) * [Reviews](https://wordpress.org/support/plugin/ultimate-member/reviews/) * 38 replies * 3 participants * Last reply from: [Champ Camba](https://wordpress.org/support/users/champsupertramp/) * Last activity: [4 years, 1 month ago](https://wordpress.org/support/topic/change-username-using-costume-field/page/3/#post-15374158) * Status: resolved
