使用PHP

Question

我一直在想办法如何解决这个问题，但我似乎无法做到。我是PHP的初学者，我现在迷路了。我想对所选复选框的值求和，并在PHP页面中发布值的总和。

这是我的HTML到目前为止

<input class="wrapped-input" type="checkbox" value="290" id="widgetu15650_input" name="custom_U15293[]" tabindex="1"/>
<label for="widgetu15650_input"></label>

到目前为止我的PHP

if (isset($_POST['u15175'])) {
    if($_POST){
        $val = 0;
        foreach($_POST['custom_U15293'] as $custom_U15293){
            $val += $custom_U15293;
        }
        echo $val;
    }
}

Answer 1

试试这个，

@Entity // This tells Hibernate to make a table out of this class
public class Hand {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
private int p1;
private String p1s;
private int p2;
private String p2s;
private int d1;
private String d1s;
private int trials;
private int score;

public Hand() {
}

如果您看到 if($_POST){ if(isset($_POST['custom_U15293']){ $val = 0; foreach($_POST['custom_U15293'] as $custom_U15293){ $val += (int) $custom_U15293; } echo $val; } else { echo 'Value not received'; } HTML代码存在问题
