PHP默认值和打印问题
[英]PHP Default value and Print Issues
问题描述
我目前正在尝试使我的php与表单位于同一页面上，正确显示值并计算总的合格分数。 我的计算遵循以下格式：
C =（（＃次完成/＃次尝试）* 100 -30）/ 20
Y =（（＃码/＃尝试）-3）/ 4
T =（（＃触地次数/＃尝试次数）* 20）
我= 2.375-（＃interceptions /＃attempts）* 35
及格分数=（（C + Y + T + I）/ 6）* 100
包含表单中值的表的默认值应为0，低于该值的表应根据合格者的评分打印差，好和好的总体评分。
如您所见，我有几个问题。 我的问题是：
通过评分未默认为0。
无论是差，好还是好，都不会打印我的总体评分。 它只打印差
我希望有人可以解释这一点。 我已经对它进行了数小时的故障排除。 不幸的是没有运气。 ps（总体评级打印两次，以查看我要使用哪个版本）
另外，除非您的计算机上装有php，否则该代码段也不会运行php。 需要服务器来查看它，即使我猜到了摘录
更新：我把20而不是4除以Y值。 那固定了我的计算，但没有固定总体评级。
第二次更新：我添加了以下行：
if(($_POST['First'] != '') && ($_POST['Last'] != ''))
这样我就可以保留表格的默认值。
我的最后一个问题是总体评分，显示正确的标签：差，好或好

我为解决问题所做的工作：
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";
}
}
//}
}
}

在这种情况下，您可以使用我的小型库ValueResolver ，例如：
$value = ValueResolver::resolve('', 'default value'); // returns 'default value' because first argument is empty
并且不要忘记使用命名空间，请use LapaLabs\\ValueResolver\\Resolver\\ValueResolver;
还可以进行类型转换，例如，如果变量的值应为integer ，则请使用以下命令：
$id = ValueResolver::toInteger('6 apples', 1); // returns 6
$id = ValueResolver::toInteger('There are no apples', 1); // returns 1 (used default value)

我可以使用PHP print作为输入字段的默认值吗？
