[英]php session foreach storing data issue
I have a form that submits data. 我有一个提交数据的表格。 Let's for example say it submits this data:
例如,假设它提交了以下数据:
Age => 23
Gender => Male
Country => UK
Now I need to store this in a session array, that I have already made. 现在,我需要将其存储在已经完成的会话数组中。 BUT, this array already exists AND contains more fields than are given by the first form.
但是,此数组已存在,并且包含的字段比第一种形式提供的字段更多。 For example, this is what the session array could look like:
例如,会话数组如下所示:
Age => Value
Gender => Value
Country => Value
State => Value
Language => Value
As you can see, only the first 3 are given with the first form. 如您所见,第一个表格只给出前三个。 I would like a for each loop that detects which values are given (in this case: age, gender and country) and then place those values within the session array.
我想要一个for每个循环,用于检测给出的值(在这种情况下:年龄,性别和国家/地区),然后将这些值放入会话数组中。
For example, the next form would give the information: 例如,下一个表格将提供以下信息:
State => Value
Language => Value
I've been trying to wrap my head around this, but I just can't find a solution.. :/ 我一直在努力解决这个问题,但是我找不到解决方法..:/
Something like: 就像是:
$valid_fields = array('Age', 'Gender', 'Country', 'State', 'Language');
foreach ($_POST as $key => $value) {
if (in_array($key, $valid_fields)) {
$_SESSION[$key] = $value;
}
}
