从复选框获取检查值 [英] Get checked values from checkboxes

问题描述

我有这个复选框，我需要得到它的检查值：

在这个例子中，我希望得到 Ubuntu ，因为它被检查。

 < div class =checkbox> 
< label for =my_label_3-4> 
< input id =my_label_3-4type =checkboxvalue =5name =my_label_3 []aria-invalid =false>< / input> 
 Windows 7,8 
< / label> 
< / div> 
< div class =checkbox> 
< label for =my_label_3-5> 
< input id =my_label_3-5type =checkboxvalue =6name =my_label_3 []aria-invalid =false>< / input> 
 Mac OS 
< / label> 
< / div> 
< div class =checkbox> 
< label for =my_label_3-6> 
< input id =my_label_3-6type =checkboxchecked =value =7name =my_label_3 []aria-invalid =false>< / input> 
 Ubuntu 
< / label> 
< / div> 
< div class =checkbox> 
< label for =my_label_3-7> 
< input id =my_label_3-7type =checkboxvalue =8name =my_label_3 []aria-invalid =false>< / input> 
 FreeBSD 
< / label> 
< / div> 
  

我该怎么做？

这是我到目前为止所做的，但没有返回任何结果：

  echo'checkbox'; 
 foreach（$ html-> find（'my_label_3'）as $ id）{
 echo $ id; //返回'checkbox'
} 
  

使用简单的HTML Dom解析过程

解决方案

尝试使用标签标识节点，如 Ubuntu 不是输入的值。它是标签的文本， input 的值是7。

  foreach（$ html-> find（'label [for ^ =my_label_3-'）as $ label）{
 if（！empty （$ label.find（'input [checked]'）））{
 echo $ label-> innertext; 
} 
} 
  

I have this check boxes that I need to get its checked values:

In this example, I would expect to get Ubuntu, because it is checked.

<div class="checkbox">
    <label for="my_label_3-4">
        <input id="my_label_3-4" type="checkbox" value="5" name="my_label_3[]" aria-invalid="false"></input>
        Windows 7, 8
    </label>
</div>
<div class="checkbox">
    <label for="my_label_3-5">
        <input id="my_label_3-5" type="checkbox" value="6" name="my_label_3[]" aria-invalid="false"></input>
        Mac OS
    </label>
</div>
<div class="checkbox">
    <label for="my_label_3-6">
        <input id="my_label_3-6" type="checkbox" checked="" value="7" name="my_label_3[]" aria-invalid="false"></input>
        Ubuntu                                  
    </label>
</div>
<div class="checkbox">
    <label for="my_label_3-7">
        <input id="my_label_3-7" type="checkbox" value="8" name="my_label_3[]" aria-invalid="false"></input>
        FreeBSD
    </label>
</div>

How do I do so?

This is what I did so far, but hasn't return any result:

echo 'checkbox';
foreach ($html->find('my_label_3') as $id) {
    echo $id; // returns 'checkbox'
}

Using Simple HTML Dom for parsing process

解决方案

try using the label to identify the nodes, as Ubuntu is not the value of the input. It is the text of the label, the value of that input is 7.

foreach ($html->find('label[for^="my_label_3-"') as $label) {
    if (!empty($label.find('input[checked]'))){
        echo $label->innertext;
    }
}
