So, i'm THIS close to being able to breakthrough with my project and be done with it (maybe.......). I just need to know one more thing. But first, I kinda have to talk about the structure of the code. It runs three different functions to affect hte total, in this case we'll say $X. $X is updated on each of the functions. Got that part working down. But now I want to say if $X > 0, give a link to the front page and allow the user to run it again (with a user input on something that will change $X), and I got that part down. Now I just need to know how to declare $X = rand(0,1000); one time, then after that, it updates and keeps course with what it is after the function. SO basically after these functions, I want the user to be able to go to the home page, input a number for the other function that helps change $X, and $X stay the same as it was after the result of the first set of functions. Then I want to be able to display the result of the three functions and $X on the front page. Or maybe I should create a new page, identical to the front page, but have the session variables be called there? I'm a bit confused. Sorry for the long wall of text as well, and I hope it makes sense

Also, I can't get it to echo $stock here. Help on that too?

Code: Select all

<!DOCTYPE HTML>

<form action = "fish.php" method = post>
Input Harvest Rate<input type="text" name="harvest" id="harvest">
<input type = "submit" value="Submit">
</form>
  <?php
$stock = rand(0,10000);
echo $stock;
?>

</html>

I can't say of how to help with most of the items, but I may be able to help with the random situation.
Try mt_rand() instead of rand(). It provides better randomization and performance.

As for displaying it, just try:

Code: Select all

echo mt_rand(0,1000);

And see if you get a result, if you don't then as you will suspect, it has to be something else causing it; such as a layer displaying over it, or something with the form.

Yeah, not sure why stock's not working. Looks like you have it correct.

I tried that and still nothing appeared. Also, now it doesn't even generate $stock. Not sure what's happening,.

Ok, I think you need to have this code done this way...
I have tested it and it works (and yes, I got the same problems as you did with your older code.

Give this a shot:

Code: Select all

 <?php
	echo '<!DOCTYPE HTML>';

	echo '<form action = "fish.php" method = post>';
	echo 'Input Harvest Rate';
	echo '<input type="text" name="harvest" id="harvest">';
	echo '<input type = "submit" value="Submit">';
	echo '</form>';

	$stock = mt_rand(0,10000);
	echo $stock;

	echo '</html>';
?>

Forgot, you will have to have the filename with a .php extension.

Thanks a bunch, Hamilton ! Now...anyone got any ideas for my other problem?

Not sure I understand your issue, let me go through it as I understand it.

You have this $X-variable, that goes through three functions and it is updated on all of these.

Not sure why you use functions but you might have a reason, or are just using word 'function' to mention it as a stage of where the $X is handled?

But according to your explanation of issue you have these,

1. If $X > 0, then >> throw a link for user to be able to declare $X again.
2. Then you have a phase where $X = rand(0,1000)?? What happens to whatever user declares?
3. ??? I lost my thought, I re-read your text and didn't find a third phase

I re-read and re-read your explanation but sorry I have some trouble understanding what you want

or is this what you want to know::

Then I want to be able to display the result of the three functions and $X on the front page.

As you mentioned also after this sentence, if the results are set by refreshing the page several times, you can use SESSION to store the value between refresh.

Or use some kind of database. In any case, if you you want a result that happens between several refreshes of page in different instances, you need to store the results in between when they meet your acceptance criteria.

When typing explanation, try pressing that enter a few times, it was really hard to read

Yeah, sorry about the explanation, haha. Basically. X is declared the mt_rand on the first page. Then, the user inputs another variable and runs the sim.

Then, three functions are run. One function adds to X, the other two take away from X. I want to then have a button that takes you back to a page where the user inputs another variable, but also keep the same X value from the previous spin and store this X value over each spin (IE X1, X2, etc.). Then display these X values on the page where the user inputs the other variable again

That make any more sense?

Yes, that makes more sense

If the storing is for one user only and is not needed 'tomorrow' for example, then use $_SESSION, to store it.
You can have an array in $_SESSION['X'] = Array(), and you just push the results to that.

Otherwise use a database.

Hope I understood what you need
