PHP Yahoo Answers Clone Script Problem

[thekooliest]

The site I am working on for myself is Answers for Pilots. I don't have any graphics, I am just trying to get the main frame working. Right now I also just have a place to enter questions and view them. I took some of this code from a free script, and am a PHP noob, so I am not sure of how to fix my problem, but I know what it wrong. When you are on the home screen and try to view a Question by clicking on it, for example: "Question #1"...And it will bring you to a page that says "Question:" and "Answer:". The code for that section is:

<strong>Title: </strong><?php echo $rsQuestion[0]->title;?><br />
<strong>Question: </strong><?php echo $rsQuestion[0]->question_text;?>

The [0] denotes the most recent question, so even if I am viewing "Question #1", it will show "Question #2". Understand?
I can change that to [1] and get the information from the second most recent question asked, "Question #1"...but I've tried a lot and have not been able to show the information for the current question. If you could please help me with this, and if you need any more code you can look on my site, or just ask.
Thanks,
Sam.

we'd probably need the name of the script you're using. if your problem is that changing [0] to [1] isn't giving you the data you want, it could be a problem with the script, or could be a problem with some edit you made (if you made any)

print_r($rsQuestion);

Will give you the entire schema of that array. You can then figure out what you need from that.

To determine if [0] or [1] (array keys) exist and contains content, you need to do this:

$title = $question = '';
if (isset($rsQuestion[0]) AND !empty($rsQuestion[0]))
{
    $title = $rsQuestion[0];
}
if (isset($rsQuestion[1]) AND !empty($rsQuestion[1]))
{
    $question = $rsQuestion[1];
}

Now you can $title and $question in your string without issue like this:

<strong>Title: </strong><?php echo $title;?><br />
<strong>Question: </strong><?php echo $question;?>
