I'm using the following code to create the database table using plugin. However, the table is neither getting created nor I'm getting any error message. The code is as follows:

    global $wpdb;
    $table_name = "tbllb_club";

    $sql = "create table $table_name (
    club_id int(11) NOT NULL auto_increment,
    project_name varchar(500) NOT NULL,
    first_name varchar(100) NOT NULL,
    school_status varchar(50) NOT NULL,
    school_name varchar(200) NOT NULL,
    school_city varchar(50) NOT NULL,
    school_state varchar(50) NOT NULL,
    year_in_school varchar(50) NOT NULL,
    age int(2) NOT NULL,
    email varchar(200) NOT NULL,
    mobile varchar(15) NOT NULL,
    chat_id  varchar(50) NOT NULL,
    facebook_page_link varchar(200) NOT NULL,
    mailing_address_street varchar(50) NOT NULL,
    mailing_address_city varchar(50) NOT NULL,
    mailing_address_state varchar(50) NOT NULL,
    mailing_address_zip char(6) NOT NULL,
    social_networking varchar(50) NOT NULL,
    organization_involvement varchar(2000) NOT NULL,
    yesclub_heard varchar(50) NOT NULL,
    volunteer_experience varchar(2000) NOT NULL,
    volunteer_reason varchar(2000) NOT NULL,
    skills varchar(2000) NOT NULL,
    creative_ideas varchar(5000) NOT NULL,
    other_information varchar(2000) NOT NULL,
    face_photo_url varchar(200),
    school_image_url varchar(200),
    video_clip_url varchar(200),
    PRIMARY KEY  (club_id)

    require_once(ABSPATH . 'wp-admin/includes/upgrade.php');

I have followed the rules as mentioned the Wordpress Codex. Please help!! Thanks in advance.

not an answer to your question, but I'm curious why you are not just using a custom post type + meta data for this? you get the WordPress API to deal with your data and don't have to write SQL queries from scratch. – Milo Aug 4 '12 at 14:58
I will try this option also... Thanks a lot Milo for the suggestion. – Pooja Aug 6 '12 at 21:35

The above code should be placed in a function and then hook that with plugin activation hook? Here's sample structure of plugin-name.php file.

Note -

  • Use CREATE TABLE IF NOT EXISTS instead only create table

Code Updated on - 2012-08-04

<?php // this code goes into your my_plugin_name.php file

function install_my_plugin() {

    global $wpdb;
    $table_name = "tbllb_club";

    //the SQL commands to create table
    $sql = "SQL_QUERY_1";
    $sql .= "SQL_QUERY_2";

    //this stuff is needed to create the table in MySQL database
    require_once(ABSPATH . 'wp-admin/includes/upgrade.php');

    add_option("my_plugin_version", "1.0");

//lets get it hooked to plugin activation


Reference -

  • Register activation hook - Use this to do some action when plugin is activated, In this case we'r calling install_my_plugin() function to create table.

Thanks Amit for the reply. I have done in the same way you have shown here but it is not working. I'm creating 2 tables using the same technique. One table is getting created but this table is not getting created. When I try to manually create this table in phpMyAdmin, it is created successfully. – Pooja Aug 4 '12 at 13:48
using same plugin to create two tables ? – amit Aug 4 '12 at 13:59
sorry, you are incorrect here: $sql = "$variable"; is perfectly valid php, double-quoted vars are expanded. – Milo Aug 4 '12 at 14:57
Thanks for pointing out, Thats My mistake. Now updated the code. – amit Aug 4 '12 at 15:05
Thanks a lot Amit. Now it is working fine with the solution provided by you. – Pooja Aug 6 '12 at 21:36
