如何“全球化” PHP变量？ [英] How to "globalize" PHP variables?

问题描述

我有一个名为ChangeApprovalInfo.php的页面 - 它有一个名为Row_Rendered的函数，如下所示：

$ p $函数Row_Rendered（）{

//要查看字段类的属性，请使用：
// var_dump（$ this->< FieldName>）;

$ RecordOwner = $ this-> RequestUser-> CurrentValue;
echo $ RecordOwner;

$ / code>

回显$ RecordOwner可以获取我在另一个sql查询时需要的数据页面....

我有另一个页面叫ChangeApprovalEdit.php - 这个页面有

pre> <？php include_onceChangeApprovalinfo.php？>


位于文件顶部。

ChangeApprovalEdit.php有一个函数，我需要在ChangedApprovalInfo.php中定义的$ RecordOwner变量

如果我在ChangeApprovalEdit.php页面上添加echo $ RecordOwner我收到一个错误，说这是一个未知的变量。我的理解是我需要使其成为全球或某些此类业务。我对PHP知之甚少，而我正在编辑的页面又长又复杂。 （对我来说，至少）

• 我需要做什么？我知道我提供的信息可能不足以回答这个问题。我甚至不知道甚至完全知道我需要问什么。如果需要更多信息，我会编辑并跟进。

文件的pastebin

  ChangeApprovalInfo.php = http://pastebin.com/bSRM1wwN 
 ChangeApprovalEdit.php = http://pastebin.com/AStG9pqb 
  

编辑：
将Row_Rendered更改为此似乎更有效。我无法看到哪里我可以稍后回应这个变量......但我正在得到这个地方......

  function Row_Rendered（）{
 //要查看字段类的属性，请使用：
 // var_dump（$ this->< FieldName>）; 
 $ GLOBALS ['RecordOwner'] = $ this-> RequestUser-> CurrentValue; 
 
  

解决方案

事情：

首先，您可以从函数中返回 $ RecordOwner ，并将其值存储在一个变量中。

 函数Row_Rendered（）{
 
 //查看字段的属性类，使用：
 // var_dump（$ this->< FieldName>）; 
 
 $ RecordOwner = $ this-> RequestUser-> CurrentValue; 
 echo $ RecordOwner; 
 
返回$ RecordOwner; 
} 
 
 //调用函数时将其存储在一个变量中。 
 $ RecordOwner = Row_Rendered（）; 
  

或者，您可以在函数内使它成为全局的：

 函数Row_Rendered（）{
 
 //要查看字段类的属性，请使用：
 // var_dump（$ this-> ;<字段名>）; 
 
 $ GLOBALS ['RecordOwner'] = $ this-> RequestUser-> CurrentValue; 
 echo $ GLOBALS ['RecordOwner']; 
} 
  

I have a page named ChangeApprovalInfo.php - It has a function called Row_Rendered as follows;

function Row_Rendered() {

    // To view properties of field class, use:
    //var_dump($this-><FieldName>);

    $RecordOwner = $this->RequestUser->CurrentValue;  
        echo $RecordOwner;
} 

Echoing $RecordOwner gets me the data I will need for a sql query on another page....

I have another page called ChangeApprovalEdit.php - This page has

<?php include_once "ChangeApprovalinfo.php" ?>

at the top of the file.

ChangeApprovalEdit.php has a function where I need the $RecordOwner variable as defined in ChangedApprovalInfo.php

If I add "echo $RecordOwner" on the ChangeApprovalEdit.php page, I get an error saying it's an unknown variable. My understanding is that I need to "make it global" or some such business. I know very little about PHP and the pages I am editing are long and complex. (to me, at least)

• What do I need to do? I know that the information I have provided might not be enough to answer the question. I don't know enough to even know exactly what I need to ask. If more information is needed, I will edit and follow up.

pastebin of the files

ChangeApprovalInfo.php = http://pastebin.com/bSRM1wwN
ChangeApprovalEdit.php = http://pastebin.com/AStG9pqb

EDIT: Changing Row_Rendered to this seems to be more effective. I'm having trouble seeing WHERE I can later echo this variable... but I'm getting somewhere with this...

function Row_Rendered() {
    // To view properties of field class, use:
    //var_dump($this-><FieldName>);
    $GLOBALS['RecordOwner'] = $this->RequestUser->CurrentValue;  
} 

解决方案

You can do a couple of things:

First, you can return $RecordOwner from the function, and store its value in a variable. This method is usually preferred.

function Row_Rendered() {

    // To view properties of field class, use:
    //var_dump($this-><FieldName>);

    $RecordOwner = $this->RequestUser->CurrentValue;  
        echo $RecordOwner;

    return $RecordOwner;
} 

// Store it in a variable when calling the function.
$RecordOwner = Row_Rendered();

Or, you can make it global inside the function:

function Row_Rendered() {

    // To view properties of field class, use:
    //var_dump($this-><FieldName>);

    $GLOBALS['RecordOwner'] = $this->RequestUser->CurrentValue;  
        echo $GLOBALS['RecordOwner'];
}
