调用WordPress插件的PHP函数

Question

So I installed this plugin https://wordpress.org/plugins/wp-db-table-editor/

In "how to install", it says I have to call the add_db_table_editor function in my theme's functions.php in order for the plugin interface to show

Installing screenshot

I added this code at the very bottom of functions.php file, and when I refresh my website, it won't load.

This is my code (i'm very new to coding):

function add_db_table_editor(){

if(function_exists(‘add_db_table_editor’)){ add_db_table_editor(‘title=Employees&table=employees’);

add_db_table_editor(array( ‘title’=>’Test title’, ‘table’=>’wp_posts’, ‘sql’=>’SELECT));

     }
}

Answer 1

In wordpress you have to go to

{wpinstallfolder}/wp-content/themes/{active_theme}

inside that active_theme folder you should find the

functions.php

Before you add any code to the functions.php you need to back it up, to revert back to in case you do not edit it properly.

Open it up and add the lines that the plugin told you to add. and save it.

This is a formated code block to help you

function add_db_table_editor(){
    if(function_exists('add_db_table_editor')){ 
        add_db_table_editor('title=Employees&table=employees');
        add_db_table_editor(array( 'title'=>'Test title', 'table'=>'wp_posts', 'sql'=>'SELECT * FROM event_registrations ORDER BY date_entered DESC'));
    }
}
