PHP - Help On Curl Post To Remote Page With Javascript

Hi all,

I am new here and I really thank God that I found this forum! I have read the materials here on working with cURL on javascript-form-submission pages. However, I can't to get my script to work. Can anybody here please help me out or drop me a hint on where to correct my script?

==Situation==

My company utilizes http://www.myfax.com/free/ to send our company faxes. My task is to write a code that would submit files for faxes electronically.

Note: The site also requires e-mail confirmation but I haven't get to that stage yet. I have run tests on submitting fax requests both by code and manually through the site, and have confirmed that the code doesn't work on the submission level because I managed to receive confirmation e-mails for manual submissions. Also, I tried my script with different staff email addresses because I figured out that it blocks only the same e-mail address from sending more than 2 faxes a day.

Code: (php) [Select]
