使用核心Joomla组件作为自定义组件的基础

Question

I'm attmpting to pull all the necessary files that make up the Weblinks core componnent out of my Joomla 2.5 installation into a separate directory so that I can use it to make a custom component with additional fields.

My problems are:

1. I can't seem to figure out all the files needed to be pulled out in order to then successfull re-install the custom component
2. I can't seem to figure out all the renaming that needs to be done in the custom component in order to ensure it doesn't corrupt the core installation when I re-install it.

Has anyone done this before? I looked at creating a custom component from scratch and it seems like far too much workfor a non web developer. This also seems overkill in order to add a couple of fields.

Answer 1

Make a clean copy (off-root) of the component's folder structure as required by the component's manifest file (the xml in the administrator/components/com_weblinks).

This should be installable and complete to start with.

Now issue the following commands if you're on Linux or OSX; or download cygwin if you're on windows

grep -rl oldname . |xargs sed -i -e 's/oldname/newname/g'
grep -rl Oldname . |xargs sed -i -e 's/Oldname/Newname/g'
grep -rl OLDNAME . |xargs sed -i -e 's/OLDNAME/NEWNAME/g'
rename 's/oldname/newname/g' *

Make sure you renamed all occurences:

grep -rli oldname .

If nothing comes up, you're good to go; else, simply grep and pipe to sed as shown above. Make sure you never use case-insensitive replacements: that would definitely break your code.

Proofread the .xml manifest manually.

Repackage, and try installing. Read any error messages (or the error log if it's not clear), you should have little to no problems making an installable package). Installing repeatedly does not cause damage (unless you make naming mistakes in the .xml files).

PS: This answers your question, but maybe @David-Frisch's suggestion could be easier and more effective in your case, you get all the component structure set up in a neat and simple style, with little redundancy in the frontend editing features, but overall a great start.

Answer 2

You can create new component easily by using joomla's Official tutorials .

First you have to identify you requirement like your component required Front end and back end or sql tables etc.

The next step is to identify you requirement matching Joomla official tutorials That you can easily get from Articles in this series section.

At the end of that tutorial you can download a com_helloworld component.

Just unzip the package and rename all the occurrence of hellowolrd from the folder structure if you are using an IDE like Dreamweaver simply achieve this by using folder search options.

This will rename you complete com_helloworld folder contained helloword text .

The final step is to rename your files all the occurrence of your helloworld in your file you have set to new name of your component. and the folder too

Then zip the package and task completed.!

Hope this make sense..
