我已尝试通过此网站进行研究以自行解决问题，但我仍然无法使用此表单来调用在提供的复选框中选择的多个选项。代码来自我下载的在线表格。这里没有其他确切的问题似乎能够帮助我。

所有表单返回都是选中的一个选项，即使选中了多个框也是如此。
答案 0 :(得分：3)
要允许多个复选框值，您必须将[]添加到name属性。 PHP然后将其视为一个数组：
<input type=checkbox name="valid_license[]" id="valid_license" ... />
然后确保将它们作为数组处理。您的$this->valid_license也会成为一个数组。
// Something like
foreach ($_POST['valid_license'] as $license) {
// Append each sanitized element onto valid_license[]
$this->valid_license[] = $this->Sanitize($license);
}
请注意，您必须为每个属性提供不同的id=属性。 HTML规范要求id属性是唯一的。现在，你们所有人都有id='valid_license'。将它们更改为id='valid_license1'或类似。
function ComposeFormtoEmail() {
$header = $this->GetHTMLHeaderPart();
$formsubmission = $this->FormSubmissionToMail();
$extra_info = $this->ExtraInfoToMail();
$footer = $this->GetHTMLFooterPart();
// Assign this to a variable
$licenses = implode(", ", $this->valid_license);
// Then insert that variable into `$message`
$message = $header."Job Application Submission From thermosealinsulation.ca :<p>$licenses</p><p>$formsubmission</p><hr/>$extra_info".$footer;
//---------------------------------------------------------------------------^^^^^^^^^^^^^^^^
return $message;
}
好的，我想我终于明白了。字段及其标题由FormSubmissionToMail()生成。这就是你需要添加implode()调用的地方，而不是像我们之前所做的那样添加ComposeFormToEmail()函数：
function FormSubmissionToMail()
{
$ret_str='';
foreach($_POST as $key=>$value)
{
if(!$this->IsInternalVariable($key))
{
// MOVED THIS BLOCK FROM BELOW...
// CHANGES BEGIN HERE.....
// This loop looks over all the $_POST values. Need to isolate the `valid_licenses` and do something special with it.
if ($key == "valid_license") {
$value = implode(", ", $value);
// Now $value will output as the comma-separated values list.
}
// CHANGES END HERE
$value = htmlentities($value,ENT_QUOTES,"UTF-8");
$value = nl2br($value);
$key = ucfirst($key);
$ret_str .= "<div class='label'>$key :</div><div class='value'>$value </div>\n";
}
}
foreach($this->fileupload_fields as $upload_field)
{
$field_name = $upload_field["name"];
if(!$this->IsFileUploaded($field_name))
{
continue;
}
$filename = basename($_FILES[$field_name]['name']);
$ret_str .= "<div class='label'>File upload '$field_name' :</div><div class='value'>$filename </div>\n";
}
return $ret_str;
}
### Now that this is the correct location, go back and remove the changes we made to `ComposeFormToEmail()`
