PHP Concrete 5将变量传递给Add.php [英] PHP Concrete 5 Pass Variables to Add.php

问题描述

我正在创建一个新块，我想在添加时将已定义的变量传递给该块实例。

I'm creating a new block and I want to pass a defined variable to the block instance on add.

在我的控制器中，我有以下内容：

In my controller, I have the following:

// declare the var
public $hasMap = 0;

public function add() {
    $this->set('hasMap', $this->generateMapNumber());
}

generateMapNumber（）函数如下：

The generateMapNumber() function looks like this:

public function generateMapNumber() {
    return intval(mt_rand(1,time()));
}

在我的add.php表单中，我有一个隐藏字段：

In my add.php form I have a hidden field:

<?php $myObj = $controller; ?>
<input type="hidden" name="hasMap" value="<?php echo $myObj->hasMap?>" />

当我创建一个新块时， hasMap 始终为 0 ，隐藏的输入值也始终为 0 。有什么建议么？谢谢！

When I create a new block, hasMap is always 0 and the hidden input value is always 0 too. Any suggestions? Thank you!

---编辑---

从Concrete5文档中：

From the concrete5 documentation:

// This...
$controller->set($key, $value)
// ... takes a string $key and a mixed $value, and makes a variable of that name 
// available from within a block's view, add or edit template. This is 
// typically used within the add(), edit() or view() function

推荐答案

这就是解决方案。在控制器中...

So here's the solution. In the controller...

public $hasMap = 0;

// no need for this:
// public function add() {  }

public function generateMapNumber() {
    if (intval($this->hasMap)>0) {
        return $this->hasMap;
    } else {
        return intval(mt_rand(1,time()));
    }
}

然后在add.php文件中...

And then in the add.php file...

<?php $myObj = $controller; ?>

<input type="hidden" name="hasMap" value="<?php echo $myObj->generateMapNumber()?>" />

它完美地工作。添加后，将生成一个新数字，并进行编辑后，将从db中的 hasMap 字段中提取现有数字。

It works perfectly. On add, a new number is generated and on edit, the existing number is drawn from the hasMap field in the db.
