Dos pronombres juntos (Double Object Pronouns)
In many cases, both a direct and indirect object pronoun will appear in the same sentence. When this occurs, the indirect object pronoun always precedes the direct object pronoun .
We can call this the "ID rule" : I = indirect object pronoun, D = direct object pronoun. If you ever forget which comes first, just think "ID", and you will have your pronoun order!
REMEMBER: Your INDIRECT OBJECT PRONOUNS are:
me, te, le . . . .nos, os, les
(indicate to or for whom something is done)
Your DIRECT OBJECT PRONOUNS are:
me, te, lo/la . . . nos, os, los/las
(answers the questions what? or whom?, directly follows your verb in a sentence - directly acted upon by verb)
Ex:
María me mostró las flores.I.O. D. O.
"Me" is the indirect object, because María is showing the flowers "to me".
"Las flores" is the direct object, since the flowers are the objects being shown, and "las flores" directly follows your verb.
If we were to rewrite the above sentence, substituting pronouns for the objects themselves, it would look like:
María me las mostró. María showed them to me.
Remember that even though we may allow our sentences to end in Indirect Object pronouns in English, we cannot do that in Spanish. For this reason, the Indirect Object pronoun comes before any other.

Ella nos la explicó.
(She explained it (the theory) to us).

(They sent it (the gift) to you).

(The man sold it (the car) to me).

Mi hermana me la compró.
(My sister bought it (the skirt) for me).
¿Él no te dio los billetes?
¿Él no te los dio?
(Didn't he give them (the tickets) to you?)
Remember: When le/les is followed by lo/la/los/las, then le/les turns to "se"!!
¿A quién le dio Javier el regalo?
-Javier se lo dio a Ana.
(the se= le, "to her", meaning to Ana)

(se= le, "to him", meaning to my boyfriend)
