How to write a custom php code in joomla

Question

我在joomla网站上工作，但是由于我是joomla的新手，所以我不知道如何为管理员编写数据上传表单。实际上，我想为管理员制作一个表单，通过该表单他可以上传有关属性的信息，很少图片和其他信息以文本框，组合框和单选按钮的形式。一旦数据上载，用户便可以通过提供一些信息（以文本框，组合框等的形式）搜索这些属性。我知道该怎么做。我知道有很多扩展，但是它们非常昂贵，这就是为什么我要自己做的事情

'very costly' is a very subjective term. I've rarely seen a Joomla add-on cost more than £30 or £50 (approx $50 - $80). Some add-ons are more perhaps double this - but they tend to be full apps that will just drop in and run a full business.

http://docs.joomla.org/ and in particular this page: http://docs.joomla.org/Component_Development should be your starting points.

As you are just starting out you probably want to follow the Joomla 1.7 items where possible. Where not possible Joomla 1.6 is almost identical internally.

Browse the code of the 'core' components that ship with Joomla - within the /components/ and /administrator/components/ folders. Download extensions from the JED (Joomla Extensions Directory) http://extensions.joomla.org/ and pick those apart too.
