用文本字段定义函数名称 [英] Define function name with text field

问题描述

我只是一个真正的PHP新手（我知道我在尝试运行之前可以走路），但我想知道是否可以通过文本字段定义函数名称。

I'm only really a novice with PHP (and I know I'm sortof trying to run before I can walk), but I would like to know if it is possible to define a functions name via a textfield.

目前，我正在使用Wordpress，因此我可以使用add_option将某些内容添加到数据库中以存储数据等，这很方便。我的想法是为幻灯片插件，它允许你有无限的幻灯片。

Currently, I am working with Wordpress so I can use add_option to add something to the database to store data, etc, which is handy. My idea is for a slideshow plugin which allows you to have unlimited slideshows.

这将通过在文本框中输入名称然后单击提交按钮来存储名称。这个名字将被赋予一个可用于显示特定幻灯片的功能。这可能吗？

It would work by typing the name into the text box then clicking the submit button to store the name. This name would then be given to a function which can be used to display that specific slideshow. Is this possible?

很抱歉，如果这看起来很混乱。我知道我想要达到的目标，但我不知道如何（但我愿意学习）。谢谢。

Sorry if this seems confusing. I know what I want to achieve, I just don't have a clue how (but I am willing to learn). Thanks.

推荐答案

1.您的插件管理页面允许命名和创建幻灯片，例如创建带有标题的帖子或图库，并添加图片。

1.your plugin admin page allows naming and creating slideshows, like creating a post or a gallery with a title, and adding images.

2.您可以在您的主题中放置一个函数调用，以在其中显示幻灯片：

2.you place a function call in your theme where you want a slideshow to appear:

if(function_exists('display_slideshow')){display_slideshow($slideshow_name)};

3.函数display_slideshow（）包含在您的插件文件中。

3.the function display_slideshow() is included in your plugin file.

function display_slideshow($slideshow_name){
            //get slideshow stuff from the database, 
            //using the name of the show passed as arg
            //write your html and php to show the images the way you design
        }
