检查输入的名称和电话号码是否与php有效

Question

我已尝试使用此代码在输入名称和编号时添加验证。但是，这段代码有问题。对nama和telepon的验证总是错误的。我在一个页面中使用表单和验证。您可以帮我解决这个问题

Answer 1

我调试了你的代码，问题是：

当您的计划检查到您的nama字段时，它会为array('letters')提供$validate选项。

 elseif (in_array('letters', $validate)) {
     if (filter_var($this->data[$type], FILTER_VALIDATE_INT) === false) {

因此，当您想要检查字母时，为什么要使用FILTER_VALIDATE_INT？

另一个问题在于：

if(!isset($this->data[$type])) {
    $this->data[$type]  =   $trimmed;
}
$this->errors[$type]    =   (empty($this->data[$type]))? 1:0;
$this->message[$type]   =   $mess;

此块在您的支票结束时。因此，在第一次运行时，您尝试检查一个空的东西，然后当方法完成时，nama将被添加到$this->data。这就是您的第二次Check电话未找到telpone的原因。因此，将此块移动到方法的顶部，然后验证，这是否存在。仅在此检查后验证格式。
