Dealing with arrays in form submissions is a pain in the ass.
Imagine you need to build a page that allows users to add multiple contacts at once. If a contact has a
, ideally the incoming request would look something like this:
The problem is that crafting a form that actually submits this format is surprisingly complicated.
...but this gives you a request that looks like this:
To get the form to submit in the correct format, you need to give each set of fields an explicit index:
...which means that when you add another set of fields, you need to change the name of every input, incrementing the index by one.
Doesn't seem too unreasonable at first, just count the sets of fields and add one for the new set right?
Wrong! What if a user removes a set of fields? Or two sets of fields? Now there might only be 3 sets remaining but the last set still has an index of 4, so just counting the fields is going to result in a collision.
So what can you do? Well, you have a few options:
All of a sudden this seems like a lot more work on the front-end than you signed up for! But there's one other option:
Submit the data in a different format and deal with it on the server.
As long as we aren't nesting past the empty square brackets, PHP is happy to let us leave out the index. So what you'll commonly see people do in this situation (and what you may have done yourself) is name the form fields like this:
The benefit of course is that now we don't have to keep track of the index. We can reuse the same markup for every set of fields, never worrying about the total number of fields in the form, or what happens when a set of fields is removed. Excellent!
The disadvantage is that now our incoming request looks like this:

The word "garment" has distinctive meanings to Latter-day Saints. The white undergarment worn by those members who have received the ordinance of the temple Endowment is a ceremonial one. All adults who enter the temple are required to wear it. In LDS temples, men and women who receive priesthood ordinances wear this undergarment and other priestly robes. The garment is worn at all times, but the robes are worn only in the temple. Having made covenants of righteousness, the members wear the garment under their regular clothing for the rest of their lives, day and night, partially to remind them of the sacred covenants they have made with God.
The white garment symbolizes purity and helps assure modesty, respect for the attributes of God, and, to the degree it is honored, a token of what Paul regarded as taking upon one the whole armor of God (

; cf. DC 27:15 ). It is an outward expression of an inward covenant, and symbolizes Christlike attributes in one's mission in life. Garments bear several simple marks of orientation toward the gospel principles of obedience, truth, life, and discipleship in Christ.
An agency of the Church manufactures these garments in contemporary, comfortable, and lightweight fabrics. They are available for purchase through Church distribution centers.
Scripture, as well as legends from many lands and cultures, points toward the significance of sacral clothing. A biblical tradition teaches that Adam and Eve, prior to their expulsion from Eden, wore sacred clothing. "Unto Adam also and to his wife did the Lord God make coats of skins, and clothed them" ( Gen. 3:21 ). These were given in a context of repentance and forgiveness, and of offering sacrifice and making covenants.
In antiquity, priestly vestments were part of widespread tradition. The Targums (Aramaic paraphrases of the Old Testament) teach that these garments were "precious garments" or "glorious garments" or "garments of honor." Rabbi Eleazer called them "coats of glory." A rabbinic source asks: "And what were those garments?" The answer is, "The vestments of the High Priesthood, with which the Almighty clothed them because Adam was the world's first-born" (Kasher,
Encyclopedia of Biblical Interpretation
, Vol. 1, p. 137). In Moses' time those who officiated in the Tabernacle wore a certain kind of garment: "And [Moses] put upon [Aaron] the coat, and girded him with the girdle, and clothed him with the robe, and put the ephod upon him, and he girded him with the curious girdle of the ephod, and bound it unto him therewith" (

; see Testament of Levi 8). Latter-day Saints similarly wear temple garments in connection with their priesthood functions.
