Question

我和PHP和CodeIgniter有一个奇怪的问题。这是我的文件的代码：

编辑：跳过这段代码，然后转到我写的第二篇。如果它可能有用，它仍保留在这里。

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

require_once ( 'utils.php');

class FooterHeader {

  // Esta clase nos permite definir el footer y sus correspondientes menus
  var $utils;
  var $controller;

  var $TOPMENU_NOT_LOGGED_IN_NAMES;
  var $TOPMENU_NOT_LOGGED_IN_LINKS;
  var $TOPMENU_LOGGED_IN_NAMES;
  var $TOPMENU_LOGGED_IN_LINKS;
  var $TOPMENU_DESIGNER_NAMES;
  var $TOPMENU_DESIGNER_LINKS;

  // Side menu
  var $SIDEMENU_NOT_LOGGED_IN_NAMES;
  var $SIDEMENU_NOT_LOGGED_IN_LINKS;
  var $SIDEMENU_LOGGED_IN_NAMES;
  var $SIDEMENU_LOGGED_IN_LINKS;
  var $SIDEMENU_DESIGNER_NAMES;
  var $SIDEMENU_DESIGNER_LINKS;

  // Main menu
  var $MAINMENU_NOT_LOGGED_IN_NAMES;
  var $MAINMENU_NOT_LOGGED_IN_LINKS;
  var $MAINMENU_LOGGED_IN_NAMES;
  var $MAINMENU_LOGGED_IN_LINKS;
  var $MAINMENU_DESIGNER_NAMES;
  var $MAINMENU_DESIGNER_LINKS;

  function FooterHeader ($controller) {
    $this->utils = new Utils ();
    $this->controller = $controller;
    include_once 'defineMenus.php';
    configVars ($this);
  }

  public function setDefaultHeader ($situation) {
    $topMenuNames = array();
    $topMenulinks = array();
    $MainMenuNames = array ();
    $MainMenuLinks = array ();
    $SideMenuLinks = array ();
    $SideMenuNames = array ();

    // dependiendo del estado del usuario, mostramos cosas u otras
    if ($situation == NOT_LOGGED_IN) {
      $topMenuNames = $this->TOPMENU_NOT_LOGGED_IN_NAMES;
      $topMenuLinks = array ('users/login', 'users/register');
      $MainMenuNames = $this->MAINMENU_NOT_LOGGED_IN_NAMES;
      $MainMenuLinks = $this->MAINMENU_NOT_LOGGED_IN_LINKS;
      $SideMenuLinks = $this->SIDEMENU_NOT_LOGGED_IN_NAMES;
      $SideMenuNames = $this->SIDEMENU_NOT_LOGGED_IN_LINKS;
    }
    else if ($situation == LOGED_IN) {
      $topMenuNames = $this->TOPMENU_LOGGED_IN_NAMES;
      $topMenuLinks = $this->TOPMENU_LOGGED_IN_LINKS;
      $MainMenuNames = $this->MAINMENU_LOGGED_IN_NAMES;
      $MainMenuLinks = $this->MAINMENU_LOGGED_IN_LINKS;
      $SideMenuLinks = $this->SIDEMENU_LOGGED_IN_NAMES;
      $SideMenuNames = $this->SIDEMENU_LOGGED_IN_LINKS;
    }
    else if ($situation == DESIGNER) {
      $topMenuNames = $this->TOPMENU_DESIGNER_NAMES;
      $topMenuLinks = $this->TOPMENU_DESIGNER_LINKS;
      $MainMenuNames = $this->MAINMENU_DESIGNER_NAMES;
      $MainMenuLinks = $this->MAINMENU_DESIGNER_LINKS;
      $SideMenuLinks = $this->SIDEMENU_DESIGNER_NAMES;
      $SideMenuNames = $this->SIDEMENU_DESIGNER_LINKS;
    }
    var_dump ($topMenuLinks);
    $this->setHeader ($topMenulinks, $topMenuNames, $MainMenuLinks, $MainMenuNames, $SideMenuLinks, $SideMenuNames);
  }

  public function setHeader ($topMenuLinks, $linkNames, $menus, $menusNames, $sideMenuLinks, $sideMenuNames) {
    var_dump ($topMenuLinks);
    $enlaces = $this->generateTopMenu ($linkNames, $topMenuLinks);
    $data['enlaces'] = $enlaces;
    $menus = $this->generateMenus ($menusNames, $menus);
    $data['menus'] = $menus;
    $sideMenus = $this->generateSideMenu ($sideMenuLinks, $sideMenuNames);
    $data['sideMenus'] = $sideMenus;

    $this->controller->load->helper('html');
    $this->controller->load->view('static/header.php', $data);
  }
[...]
}

不要全部阅读。这不是必需的。只需看看两个var_dump来电。第一个var_dump打印出来：

array (size=2)
  0 => string 'users/login' (length=11)
  1 => string 'users/register' (length=14)

第二个：

array (size=0)
  empty

我不知道为什么我的变量未初始化。其余的变量都没问题。

编辑：我已将代码简化为最大值：

<?php
class FooterHeader {

  function FooterHeader ($controller) {
    $this->controller = $controller;
  }

  public function setDefaultHeader ($situation) {
    $topMenulinks = array();
    // dependiendo del estado del usuario, mostramos cosas u otras
    $topMenuLinks = array ('users/login', 'users/register');
    var_dump ($topMenuLinks);
    $this->setHeader ($topMenulinks);
  }

  public function setHeader ($topMenuLinks) {
    var_dump ($topMenuLinks);
  }
}

?>

但问题仍然存在。

编辑：执行调用的代码是：

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

require_once ( 'utils/footerHeader.php');
require_once ( 'utils/defineMenus.php');

class WelcomePage extends CI_Controller {

  var $fh;

  function WelcomePage () {
    parent::__construct();
    $this->fh = new footerHeader($this);

    $this->load->helper('url');
  }
    public function index()
    {
    // seteamos el header (el defecto)
    $this->fh->setDefaultHeader(NOT_LOGGED_IN);

    $this->load->view('subirDisenyoEjemplo.php');

    //$this->fh->setFooter();
    }
}

/* End of file welcomePage.php */
/* Location: ./application/controllers/welcomePage.php */
?>

Answer 1

编辑：注意大写：

var_dump ($topMenuLinks);
$this->setHeader ($topMenulinks);

$ topMenu L 墨水与$ topMenu l 墨水相比。我在我的服务器上尝试了它，它会立即弹出一个未初始化的变量。

<强>最初：

数组的内容取决于if - else if结构的结果。仅在这种情况下

if ($situation == NOT_LOGGED_IN) {

将为数组分配其值，如第一个var_dump()。否则，您将最终得到一个空数组，因为它被初始化为

$topMenulinks = array();

如果situation或LOGED_IN未涵盖任何DESIGNER。请注意LOGED_IN中缺少的 G 。

Answer 2

没有调用代码，很难确定，但我确实找到了这个：

$situation == LOGED_IN
$situation == LOGGED_IN

函数上未初始化的第一个变量
