You have to reset the drop down on clicking the radio button. Also I can not find any reason to the name of the drop down as it is the same of the radio buttons.

Please Notice the changes in the value attribute changes of the radio buttons.

You are already in the article-set element when you start and $article is an element, not a variable, so the $ should be removed.

First, it is mathematically impossible to recover an original message from a message digest. A message digest is a small amount of information that is intended to act as a sort of fingerprint for a large amount of information. For example, in one of the simplest forms, a message digest might be simply the sum of the numerical values of the characters in a message. You obviously cannot recover the original message just from the sum of its characters. (Two messages that are anagrams would have the same sum, so the sum would not tell you which of the two messages was the original. And a message changed by increasing one character and decreasing another would have the same sum as the original message, so, again, the sum would not distinguish them.) This is just an example—actual cryptographic hashes are more complicated than simple sums.

Second, cryptographic hashes and the message digests they produce are usually designed to be difficult to invert. It is intended to be difficult to find any message whose digest equals a given value.

If you want cryptographic functions that change a message to a cryptic form and then invert it, you are looking for encryption and decryption, not hashes or digests.

How is the ARTCOMP etc (so the more indented part of the data) processed? FK relations? Because I think you just ran out of memory and MySQL decided to use tmp, or the system started swapping.
