[SOLVED] PHP Array

[TOMMURRAY]

Hi all, I have a script (below) that is used to calculate the points on a golf scoring system called stableford. I would like to amend the code so that it runs through the results of a form submitted for all 18 holes. The script below only calculates for one hole, how could i go about doing this?

 

For each hole the following will have different unique values:

 

$score

$si

$par

 

What would be the best way of doing this and is there any good resources that you could point me in the direction of?

 

Thank you in advance

 

Tom

<?php

$count = 0;

$score = 5;

$si = 1;

$handicap = 28;

$par = 4;

$stablefordpoints =0;

 

if ($handicap >= 0) {

if ($score > 0) {

$sp = 0;

if ($handicap == 0) {

$sp = $score;

} else if ($handicap <= 18){

For ($count = 1; $count <= $handicap; $count++){

if ($si == $count) {

$sp = $score - 1;

} else {

$sp = $score;

}

}

} else if ($handicap >= 19 && $handicap <= 36){

$handicap = $handicap - 18;

For ($count = 1; $count <= $handicap; $count++){

if ($si <= $count) {

$sp = $score - 2;

} else {

$sp = $score -1;

}

}

}

 

if ($sp - 1 == $par){

  $stablefordpoints = 1;

} elseif ($sp == $par){

  $stablefordpoints = 2;

} elseif ($sp + 1 == $par){

$stablefordpoints = 3;

} elseif ($sp + 2 == $par){

  $stablefordpoints = 4;

} elseif ($sp + 3 == $par){

  $stablefordpoints = 5;

} elseif ($sp + 4 == $par){

  $stablefordpoints = 6;

}                               

} 

if (!empty($stablefordpoints)) echo $stablefordpoints; 

 

}

Try something like this. Keep in mind that I don't fully understand what your loops are doing, so I'm simply reworking your script into pieces:

<?php
function calcHole($hc, $score, $si, $par)
{
if ($score >0)
{
	$sp = 0;
	if ($hc == 0)
	{
		$sp = $score;
	} elseif ($hc <= 18) {
		for ($count = 1; $count <= $hc; $count++)
		{
			if ($si == $count) $sp = $score - 1;
			else $sp = $score;
		}
	}
} elseif ($hc >= 19 && $hc <= 36) {
	$hc -= 18;
	for ($count = 1; $count <= $hc; $count++)
	{
		if ($si <= $count) $sp = $score - 2;
		else $sp = $score - 1;
	}
}

for ($i = -1; $i < 5; $i++)
{
	if ($sp + $i == $par) $points = $i + 2;
}

return $points;
}

function calcAllSubmitted($arr, $handicap)
{
$total = 0;
foreach ($arr['score'] as $k => $v)
{
	if (!empty($v) && !empty($arr['si'][$k]) && !empty( $arr['par'][$k]))
	{
		$total += calcHole($handicap, $v, $arr['si'][$k], $arr['par'][$k]);
	}
}
return $total;
}

if (isset($_POST['submit']))
{
echo "Form submitted.<br />Total score: " . calcAllSubmitted($_POST, 10) . "<br />\n";
}
?>

<form name="calc" action="" method="post">
<table>
<tr>
<th>Hole</th><th>Score</th><th>SI</th><th>Par</th>
</tr>
<?php
for ($i = 1; $i < 19; $i++)
{
echo "<tr>\n";
echo "<td>Hole #{$i}</td>\n";
echo "<td><input type=\"text\" size=\"4\" name=\"score[]\" /></td>";
echo "<td><input type=\"text\" size=\"4\" name=\"si[]\" /></td>";
echo "<td><input type=\"text\" size=\"4\" name=\"par[]\" /></td>";
echo "</tr>\n";
}
?>
<tr>
<td colspan="4"><input type="submit" name="submit" value="Calculate" /></td>
</tr>
</table>
</form>

 

This does two things:

 

First, it auto generates an 18 hole form for you.

Second, it calculates your score based on what has been submitted only. If you leave some holes out, it calculates only those fields that have been filled.

Thank You for all you help that was exactly what I was looking to do, just could not get my head around the whole array issue. Thank you once again for giving me the solid foundation to build the rest of my script around.

 

Cheers

I have just noticed a discrepancy in the calculations, the calculations are fine if the person has "0" handicap. But if the person has a handicap of say "1" then the whole that has a stroke index (si) of "1" the person gets a stroke deducted.

 

E.G. if the par for the hole is 4 and the person takes 4 shots, they get a stroke deducted so the total shots for that hole would be 3. Which would then get a total of 3 points. But in the reply above the total points would be 2.

 

Does anyone have any ideas were the problem lies?

 

Thank You

 

obsidian  I can't thank you enough for the contribution you have mad.

Just to let you know that i have solved the problem, if anyone is interested in the answer let me know an I will post but the majority of the script is that of obsidian post.

 

Thank You
