PHP遍历表单值 [英] PHP Loop through form values

问题描述

我有一个表单，其中提交了许多小字段，我需要遍历这些小字段并对其执行操作.

I have a form that submits lots of small fields that I need to loop through and perform actions on.

表单如下:

<input class="" type="hidden" name="pid" value="10">
<input class="" type="hidden" name="date" value="01-01-2014">

然后大约有100-200 ...

Then around 100 - 200 of these...

<input class="minnight" type="text" name="minnight_12_2014-03-06" value="2" size="1">
<input class="minnight" type="text" name="minnight_12_2014-03-07" value="2" size="1">
<input class="minnight" type="text" name="minnight_12_2014-03-08" value="1" size="1">
<input class="minnight" type="text" name="minnight_13_2014-03-06" value="3" size="1">
<input class="minnight" type="text" name="minnight_13_2014-03-07" value="2" size="1">
<input class="minnight" type="text" name="minnight_13_2014-03-08" value="4" size="1">
<input class="minnight" type="text" name="minnight_14_2014-03-06" value="1" size="1">
<input class="minnight" type="text" name="minnight_14_2014-03-07" value="2" size="1">
<input class="minnight" type="text" name="minnight_14_2014-03-08" value="2" size="1">

提交表单后，我需要遍历每个"minnight"字段，将"12_2014-03-06"提取到"12"和"2014-03-06"中，将它们都存储在vars中，最后执行数据库查询，然后再转到下一个查询.

When the form is submitted, I need to loop through each "minnight" field, extract the "12_2014-03-06" into "12" and "2014-03-06", store them both in vars and finally do a database query before moving to the next one.

任何有关我应该从这个烂摊子开始的指针吗?

Any pointers on where I should start with this mess?

推荐答案

使用 POST变量

尝试以下方法:

// Loop over each item in the form.
foreach($_POST as $name => $value) {
    // Split the name into an array on each underscore.
    $splitString = explode("_", $name);

    // If the data begins with "minnight", use it.
    if ($splitString[0] == "minnight") {
        // Set the other desired values into variables.
        $secondValue = $splitString[1];
        $thirdValue= $splitString[2];

        // Database query goes here.
    }
}
