In the same sense that you think it might be easier for me to create 100 different HTML documents than ask for help with PHP on this forum
Well, you dont have to write PHP scripts yourself, or even hire a programmer to write them for you. The area of content management systems happens to be one that has been flooded, and you can easily find open source and/or zero price pre-made CMS scripts such as Mambo online.
Would'nt it have saved you much time typing to correct the one or two line of code that what I am trying to do requires?
Well, the answer is that:
<? $post $_GET["a"] ?>
should be:
<?php echo $_GET["a"]; ?>
But the use of echo (or print, which is almost synonymous) is introduced in any "hello world" introductory script. If you cannot get this right, I dont see how you can have any hope to getting the other parts of your script to work. All that will happen is that you will become frustrated, since you are trying to run before you can walk, by trying to do things way beyond what you are currently capable of.
I didnt know PHP was a forbidden language only shared with those who are masters of the art
If it was forbidden, I would be executed for referring you to resources such as the PHP Manual :p
