PHP gurus,
I am having a page named scene1.php, which got link to
playvoice.php, one drop down list box and a submit
button. I will try to explain what i want from this
page as much clearly as possible with the following
points.
1. Scene1.php appears on the user screen after it gets
redirected from a page named redirect1.php
2. Initially there won't be any submit button and the
page will have only link to playvoice.php and the
dropdown list box.
3. After the user clicks on the 'Play voice file' link
which leads to playvoice.php, he will go to
phpvoice.php which shows just one line like 'Played a
voice file' for about 3 seconds on the user screen and
he will be redirected back to scene1.php
4. Now the latest scene1.php won't have a 'Play voice
file' link but just a text 'Play voice file', dropdown
box and now the submit button appears on the screen.
5. As the user clicks on the submit button, the
opinion will enter into the database and a link 'Go to
the next scenario' appears on his screen, after he
clicks it he will go to redirect2.php.
Now what my problem is the logic which i wrote within
the if statement(code is below) is not working, but
directly the logic within the else statement is
appearing on the user screen(step 4 is coming directly
instead of step 2 coming first), which is preventing
the user from clicking on the link 'Play voice
file'(as there is no link at all, just text). So what
i feel is the $HTTP_REFERER variable is not catching
redirect1.php into it. I want to know where i am going
wrong in using that.
Thanks a lot to whoever responds
