Definition at Usage

formmethod Attribute na nagtutukoy sa HTTP method na gagamitin para i-submit ang form data. Ang attribute na ito ay nagpapatunay sa attribute ng form na method.

formmethod Ang attribute na ito ay ginagamit lamang para sa type="submit" ng pindutin.

Ang form data ay maaaring ipadala bilang URL variable (gamit method="get") o ipapadala bilang HTTP post (gamit method="post")

Mga pagsasalungat sa "get" method:

  • Ipinapagkakabit nito ang form data bilang form na may pangalan at halaga
  • Ito ay napaka-kapaki-pakinabang para sa mga form submission na gusto ng user na mag bookmark ng mga resulta
  • May limitasyon ang dami ng datos na maaaring ilagay sa URL (kaiba ang browser), kaya hindi maaaring tiyakin na ang lahat ng form data ay maaaring ma-transmit nang tama.
  • Huwag kailanman gamitin ang "get" method para ipasa ang sensitive information! (Ang password o ibang sensitive information ay maaring lumitaw sa address bar ng browser)

Mga pagsasalungat sa "post" method:

  • Ipinapadala nito ang form data bilang HTTP POST transaction
  • Ang form na isinasubmit gamit ang "post" method ay hindi maaaring isave bilang bookmark
  • Kumpara sa "get" method, ang "post" method ay mas matibay at ligtas
  • Wala itong limitasyon sa laki

Mga halimbawa
