New to Pathfinder, Having Trouble with Build (Druid to Eldritch)

[VigorBird]

Hello everyone! I'm new to Pathfinder. I used to play AD&D (and a bit of D&D 3.5) many years ago and now I'm learning again from scratch on Pathfinder. Now, I'm having trouble ascertaining the Druid as a spellcaster, to be eligible for the Eldritch Knight prestige. The Pathfinder Corebook did not mention or list any recommendations for spellcasting classes as per-requisities. It only says "Able to cast 3rd-level arcane spells."

I went on anther forum and found this: "'Able to cast 3rd level spells' means a Wizard is eligible after 5th level, a Sorcerer after 6th, and a Bard after 7th or 8th (depending on Cha), a Cleric after 5th, a Druid after 5th, a Paladin after 11th or 12th (depending on Wis), and a Ranger after 11th or 12th (depending on Wis)

'Caster Level 5th' means a Cleric, Druid, Wizard, Sorcerer, or Bard is eligble after 5th level, and a Paladin or Ranger is eligible after 10th level."

However, that information is nowhere to be found in the corebook (so far to my knowledge.) I would like to make certain this is right.

The plan is to have the character become a Wild, Chaotic Good/Lawful Neutral Elf "Battlemage" type that is able to wield swords and use spells with some light or medium armor. I might choose Paladin or Fighter for the martial weapon proficiency.

Any help and information on this would be much appreciated. Thank you!

Druids are divine casters, not arcane.
So would never qualify for eldritch knight prestige class.

Have you looked at the PRD (pathfinder rules document)?
It's available for viewing on the internet so you can take a look at rules past the base book.
Magus is in the ultimate magic book as an additional class'

I mention this as it includes the rules for the magus, an arcane class that uses weapons and armor and might be something you'd want to play.
