从具有相同名称的多个输入字段中检索数据

Question

I have a form that you dynamically creates new input fields (type=hidden) which when the form is sent should be retrieved by my php code. However, by the reason that the number of input fields can differ I gave them the same name. The problem however is that I don't know how to retrieve it, or more correctly, what to do with what's retrieved.

from the form:

...
<input type='hidden' name='newListObject' value='0' />
<input type='hidden' name='newListObject' value='1' />
<input type='hidden' name='newListObject' value='2' />
<input type='hidden' name='newListObject' value='3' />
...

from php code (listView.php):

private $m_newListObject = 'newListObject';
...
if (isset($_POST[$this->newListObject])) {
    $listObjects = $_POST[$this->m_newListObject];
}

from php code (listModel.php):

//Below doesn't work because $listObjects isn't an array

foreach ($listObjects as $listObject) {
    $query = "INSERT INTO listElement (listElemName, listId) VALUES(?, ?)";

    $stmt = $this->m_db->Prepare($query);

    $stmt->bind_param('si', $listObject, $listId);

    $ret = $this->m_db->RunInsertQuery($stmt);

}

Answer 1

<input type='hidden' name='newListObject[]' value='0' />
<input type='hidden' name='newListObject[]' value='1' />
<input type='hidden' name='newListObject[]' value='2' />
<input type='hidden' name='newListObject[]' value='3' />

And use $_REQUEST['newListObject'] as an array() now.
