我正在从表单添加一个项目数组,如果所有项目都是空的,我想执行一些验证并添加到错误字符串.所以我有:

$array = array(
    'RequestID'       => $_POST["RequestID"],
    'ClientName'      => $_POST["ClientName"],
    'Username'        => $_POST["Username"],
    'RequestAssignee' => $_POST["RequestAssignee"],
    'Status'          => $_POST["Status"],
    'Priority'        => $_POST["Priority"]
);

然后,如果所有数组元素都为空,则执行:

$error_str .= '<li>Please enter a value into at least one of the fields regarding the request you are searching for.</li>';
