trigger to fetch the custom metadata to user

Hello Guys,

I am working on custom metadata, I have custom meta data "Org_Email_Signature__mdt" and is having field type Long text Area "Email_Signature__c".

Now, when I create a new user, I need to fetch that custom meta data to a field "Signature" in user object. I need to write a trigger for this.

Please help me to achieve this functionality.

Hi sainath sai,

You may try this way, and let me know if it helps you!!
trigger UserUpdate on User (before insert) {
	List<Org_Email_Signature__mdt> lstMetaData = [SELECT Email_Signature__c FROM Org_Email_Signature__mdt];	
    if(trigger.isInsert && trigger.isBefore){
        for(User objNewUser : {
            objNewUser.Email = 'TestUser' + lstMetaData[0].Email_Signature__c; // COnsidering : lstMetaData[0].Email_Signature__c is having ""

Hi sainath,

Please find below snippet.

trigger userSignature on User (before insert,after insert){
     if(trigger.isBefore && Trigger.isInsert){
        Org_Email_Signature__mdt[] signature = [SELECT MasterLabel,Email_Signature__c FROM Org_Email_Signature__mdt];
        if(signature!=nulll & !signature.isEmpty()){
            for(user usr :{
                usr.Signature = signature[0].Email_Signature__c;
If you have any field on custom meta data that you want to compare before assigning the signaure , you can put it as a condition.

Please close this question if you find this solution correct or working.

Hi Sainath,

Below code can fulfill your requirements. Hope this will work for you.

trigger UserMetadataUpdate on User (before insert) {
    List<Org_Email_Signature__mdt> metadataList =  new List<Org_Email_Signature__mdt>();
    metadataList = [SELECT Email_Signature__c FROM Org_Email_Signature__mdt];
    if(trigger.isInsert && trigger.isBefore){
        for(User objUser : {
            objUser.Email = metadataList[0].Email_Signature__c; 

Please mark this as best answer if this solves your problem.
