text - 存储数据的有效方法

Question

我有一个表格，分为不同的日子，从周一到周四。

大多数日子包含两个班级，每个班级有 2 个不同的可用时间（有些只包含 1 个）？

Answer 1

您可以使用多维数组来做到这一点：

<?php
echo '<pre>';
print_r($_POST);
echo '</pre>';
?>

<form method="POST" action="">
    <fieldset style="border:#00FFFF 3px solid">
        <legend>Monday</legend>

        Yoga Class: (Becc)<br>
        <input type="checkbox" name="classtimes[Yoga][monday][]" value="9am-11am">9am-11am<br>
        <input type="checkbox" name="classtimes[Yoga][monday][]" value="12pm-3pm">12pm-3pm<br>
        <br>
        Muay Thai Fitness: (Royce)<br>
        <input type="checkbox" name="classtimes[Muay Thai][monday][]" value="8am-10am">8am-10am<br>
        <input type="checkbox" name="classtimes[Muay Thai][monday][]" value="3pm-6pm">3pm-6pm<br>
    </fieldset>

    <fieldset style="border:#00FFFF 3px solid">
        <legend>Tuesday</legend>

        Yoga Class: (Becc)<br>
        <input type="checkbox" name="classtimes[Yoga][tuesday][]" value="9am-11am">9am-11am<br>
        <input type="checkbox" name="classtimes[Yoga][tuesday][]" value="12pm-3pm">12pm-3pm<br>
        <br>
        Muay Thai Fitness: (Royce)<br>
        <input type="checkbox" name="classtimes[Muay Thai][tuesday][]" value="8am-10am">8am-10am<br>
        <input type="checkbox" name="classtimes[Muay Thai][tuesday][]" value="3pm-6pm">3pm-6pm<br>
    </fieldset>


    <input type="submit">
</form>

输出将是：

Array
(
    [classtimes] => Array
        (
            [Yoga] => Array
                (
                    [monday] => Array
                        (
                            [0] => 9am-11am
                        )

                    [tuesday] => Array
                        (
                            [0] => 9am-11am
                        )

                )

            [Muay Thai] => Array
                (
                    [monday] => Array
                        (
                            [0] => 8am-10am
                            [1] => 3pm-6pm
                        )

                    [tuesday] => Array
                        (
                            [0] => 8am-10am
                            [1] => 3pm-6pm
                        )

                )

        )

)

Answer 2

<fieldset style="border:#00FFFF 3px solid">
<legend>Tuesday</legend>

Yoga Class: (Becc)<br>
<input type="checkbox" name="classtimes[yoga][]" value="9am-11am">9am-11am<br>
<input type="checkbox" name="classtimes[yoga][]" value="12pm-3pm">12pm-3pm<br>
<br>
Muay Thai Fitness: (Royce)<br>
<input type="checkbox" name="classtimes[muay][]" value="8am-10am">8am-10am<br>
<input type="checkbox" name="classtimes[muay][]" value="3pm-6pm">3pm-6pm<br>

</fieldset>

然后在你的 PHP 中：

foreach($_POST["classtimes"]["yoga"] as $classtimes){
     echo $classtimes;
}

Answer 3

当我做这种事情时，我通常会在复选框名称中添加一些内容，以提供其他信息，例如：

Yoga Class: (Becc)<br>
<input type="checkbox" name="0classtimes0" value="9am-11am">9am-11am<br>
<input type="checkbox" name="0classtimes0" value="12pm-3pm">12pm-3pm<br>
<br>
Muay Thai Fitness: (Royce)<br>
<input type="checkbox" name="0classtimes1" value="8am-10am">8am-10am<br>
<input type="checkbox" name="0classtimes1" value="3pm-6pm">3pm-6pm<br>

这样你就有了：第一个数字是星期几的索引，第二个数字是所述日期的类的索引。

您可以使用以下方式捕获 JQuery 中的变量：

$("input:checked").each(function(){
    var id=$(this).attr("name"); //this gives you the XcasstimesY
    var value=$(this).val(); //this gives you the value(time) of the checked value
    //here you can get this info into an array, or any other variable you want to use to submit it!
});

当您在 PHP 中收到此信息时，假设您使用的是 POST：

$x=0;
while($x<6) //6 days
    $y=0;
    while(isset($_POST[$x.'casstimes'.$y])){
        echo "On day $x class $y the selected time was".$_POST[$x.'casstimes'.$y];
        $y++;
    }
    $x++;
}
