Hi Gurunath,

Its difficult to write validation in trigger so can u use validation rule like this ('dd-mm-yyyy') try below code.

NOT(REGEX( date_of _last_flight__c ,'^(?:0[1-9]|0[1-9]|1[0-9]|2[0-9]|3[0-1])[-](?:0[1-9]|0[1-9]|1[0-2])[-](1[9][0-9][0-9]|2[0][0-9][0-9])$'))&&NOT(ISBLANK(DateOfBirth__c))

thanks for your replay ...........however i cpoied what ur suggest like 

NOT(REGEX( date_of _last_flight__c ,'^(?:0[1-9]|0[1-9]|1[0-9]|2[0-9]|3[0-1])[-](?:0[1-9]|0[1-9]|1[0-2])[-](1[9][0-9][0-9]|2[0][0-9][0-9])$'))

Hi Gurunath,

try this validation rule:-

NOT(REGEX(date_of _last_flight__c,"[0-9]{1,2}[-]{1}[0-9]{1,2}[-]{1}[0-9]{4}"))

Hi,

 

 dont now whether i am right or wrong  and wrote a trigger like this

 

trigger Validation_Aircraft on Aircraft_Contact__c (before insert,before Update) {

public Integer th {get;set;}

public String X = '[0-9]{1,2}[-]{1}[0-9]{1,2}[-]{1}[0-9]{4}';


for(Aircraft_Contact__c AC: Trigger.new){

if(Ac.Total_Hours__c != Th && 'Ac.Date_of_Last_Flight__c' != X && 'AC.Date_of_Last_SIM__c '!= X){

Trigger.new[0].addError(' Hours In Numeric Format and Date should be in DD-MM-YYYY format ');
}
}
}

 

any one please suggest me wrong or right  here Date_of_Last_Flight__c,Date_of_Last_SIM__c are fields tpye is date.......

Hi Gurunath,

You don't need a trigger for this validation rule will be enough.
Use the validation which i have given that's more than enough
