PHP Default value and Print Issues - php

Question

I am currently trying to make my php, on the same page as the form, display the values correctly and calculate the overall passer rating. My calculations follow the formatting this way:
C = ((# completions/#attempts) *100 -30)/20
Y= ((# yards/#attempts) -3)/4
T = ((#touchdowns/#attempts) *20)
I = 2.375 - (#interceptions/#attempts) * 35
Pass Rating = ((C+Y+T+I)/6) *100
The table that holds the values from the form should have a default value of 0 and below it should print the overall rating of Poor, Good and Great depending on the passer rating.
As you see I have a few issues.
My issues are:
The Passing Rating doesn't default to 0.
My Overall Rating doesn't print whether it is Poor, Good, or Great. It only prints Poor
I was hoping someone can explain this. I have been troubleshooting it for hours now. No luck sadly. ps(overall rating printed twice to see which version I want to use)
Also the snippet won't run the php unless you have php on your comp. Need a server to see it even with the snippet I guess
UPDATE: I put 20 instead of 4 to divide in Y value. That fixed my calculations but not the overall rating.
SECOND UPDATE: I added the line:
if(($_POST['First'] != '') && ($_POST['Last'] != ''))
so that I can keep my defaults for the table.
My last issues is now the Overall Rating displaying the correct label of either Poor, Good or Great

Answer 1

What I did to fix my issues:
if(is_numeric($completions) && is_numeric($attempts) && is_numeric($yards)
&& is_numeric($touchdowns) && is_numeric($interceptions)) {
//if(($_POST['completions'] >0) && ($_POST['attempts'] >0) && ($_POST['yards'] >0)
// && ($_POST['touchdowns'] >0) && ($_POST['interceptions'] >0) ){
if(($_POST['First'] != '') && ($_POST['Last'] != '')){
// $TotalScore = rating($completions, $attempts, $yards,
// $touchdowns, $interceptions);
if(($_POST['completions'] <0) || ($_POST['attempts'] <0) || ($_POST['yards'] <0)
|| ($_POST['touchdowns'] <0) || ($_POST['interceptions'] <0) ){
$score = "</br></br><strong>Invalid Input!</strong></br>Please Provide non-Negative Numbers.";
}
//echo $TotalScore;
else {
$TotalScore = rating($completions, $attempts, $yards,
$touchdowns, $interceptions);
if($TotalScore < 0) {
$score = "</br></br><strong>Invalid Results</strong></br>Please review over your scores. The Passing Rating shouldn't be negative.";
}
if($TotalScore > 0 && $TotalScore <85){
$score = "Poor";
}
elseif($TotalScore >=85 && $TotalScore <90){
$score = "Mediocre";
}
elseif ($TotalScore >=90 && $TotalScore <95){
$score = "Good";
}
elseif ($TotalScore >= 95){
$score = "Great";
}
}
//}
}
}

Answer 2

You could use my tiny library ValueResolver in this case, for example:
$value = ValueResolver::resolve('', 'default value'); // returns 'default value' because first argument is empty
and don't forget to use namespace use LapaLabs\ValueResolver\Resolver\ValueResolver;
There are also ability to typecasting, for example if your variable's value should be integer, so use this:
$id = ValueResolver::toInteger('6 apples', 1); // returns 6
$id = ValueResolver::toInteger('There are no apples', 1); // returns 1 (used default value)
Check the docs for more examples
