将新值重新分配给全局变量Laravel PHP [英] Reassign with new value to global variable Laravel PHP

问题描述

我的Laravel项目中有以下代码段，其中我试图在方法ValidateValue()中将值重新分配给全局变量$ischecked和$isselectedValue，并且尝试访问相同的代码具有第二个方法useThoseValues()中更新后的值的变量，但我无法获取更新后的值.请帮助我

I have a below kind of snippet in my Laravel project where I'm trying to re-assign value to the global variable $ischecked and $isselectedValue in a method ValidateValue() and I'm trying to access the same variable with the updated values in second method called useThoseValues() but I couldn't get the updated value. Kindly help me on this

class testController extends controller {

  public $isChecked = false;
  public $isSelectedValue = 0;

  public function ValidateValue(Request $req)
  {
    $isChecked = $req->checked;
    $isSelectedValue = $req->value;
  }

  public function UsethoseValues()
  {
    if ($this->isChecked) { // this variable values is not getting updated
    }
  }
}

推荐答案

您需要在ValidateValue函数中使用$this引用/更新$isChecked属性.因此，您更新的代码应为:

You need to reference/update $isChecked property using $this inside ValidateValue function. So your updated code should be:

public function ValidateValue(Request $req)
{
    $this->isChecked = $req->checked;
    $this->isSelectedValue = $req->value;
}
