[SalesForce] How to disable or readonly lookup field in standard page

EDIT:

On a standard page. NOT using VF page

Is it possible to write a validation rule or any approach to make a field disabled once the user save?

I have a page with couple of fields including lookup and once the user save the record I like to prevent user from changing the lookup fields.

You can add a validation rule that uses ISCHANGED to compare the values of the lookup fields to their previous values. If the user is attempting to change any of the lookups, the rule will throw an error:

OR(
  ISCHANGED(Lookup_1__c),
  ISCHANGED(Lookup_2__c),
  ISCHANGED(Lookup_3__c),
  ISCHANGED(Lookup_4__c)
)

if you want to make this field readonly from all the interface for any or all the profiles then you need to go to field level security. Setup -> Security Controls-> Field Accessibility -> now select the object which contains this field. Then click on View by Fields. Now select your field from the drop down. Next to the profile for which you want this field to be read only click on editable or hidden. From the next page under Field level security select 'Read only'.

[SalesForce] write a validation rule to make a field enabled or disabled based on picklist value

You can use the validation rule to make sure that the record cannot be saved unless the Days text field is filled in if the picklist value is 'other'.

AND(
    ISPICKVAL(Cycle__c, "other"),
    ISBLANK(Days__c)
)

This will give the user an error if they try to save a record where the picklist value os other and the days field is left blank.

You cannot though control whether or not the days field is enabled though. You would need a visualforce page to accomplish this functionality.
