There are tables for posts and their meta data, users and their meta data, site options and more. And for the most part those work just fine. Even if you have a slightly complex website, you can use custom post types and custom fields to accomplish the job. Sometimes you need to create custom so that you have more control.
Between the custom post types and custom fields ACF, Pods, etc. Gravity Forms has custom tables, and Easy Digital Downloads is going to be making the switch over to custom tables in as well.
And Sports Bench is built with custom tables.
Plus, you know the structure of the table s which makes it easier to write code to get the data. Creating a new website can be a challenge. But keep it up and running efficiently can be a challenge.
You have to make sure things are updated and running smoothly because if your site is down, no one can find or read your story. So our MySQL statement to create a table is super simple. So in MySQL, our statement would look like this.
Now to write this in the WordPress way. All of the following code will go in your functions. These are things that will just make our process easier. Next we need to name the table. So, our final code will look like this. This makes sure this code is called when we activate this plugin. So, what can you do with custom tables? But it does give you another solution to fix a problem. I can give you an answer for every site because every site is different.
Any advice? Hope this helps! I guess you would only get an error message if the table is already there but I am not sure if an error message would cause issues at any point.

Naturally, tables are divided into columns that display a particular type of information. Each table has a set of predefined default columns that are displayed.
Custom columns are columns that plugins can add to any of these tables to display plugin specific information related to the data type of the table. There are probably very few, if any instances where a plugin has to add custom columns to a table. There is always some other way to convey information, a separate settings page or a completely separate custom table.
On the other hand, there are several reasons to add custom columns. Users are already familiar with the List Tables. They know these tables contain information and action links related to each data type for which the table exists.
It thus makes complete sense for plugins that have additional information or action links related to the same data type to include such information on the same table.
Doing so enhances the user experience by placing related information and actions where they would intuitively expect to find it. Adding a custom column can be cleaner and more efficient than adding an entire new settings page to represent the same thing.
Users are then made more comfortable with the strange new components of your plugin. Your plugin will be better integrated with the default look and feel of other admin screens by using custom columns.
This is not exactly correct. The actual tables are output by objects created from extensions of that generic class. Each WordPress data type that is displayed in a table has its own extension.
Top Seven Best Plugins for Creating Tables in WordPress (2020)
Typical of a base class, all the generic properties and methods are defined here. The extensions then define properties and methods that specifically address any peculiarities of the particular data type. Doing it this way ensures a consistent user interface between all the different data types. When a List Table object is instantiated, some basic data relating to the admin screen is initialized.
Finally, the display method is called to output the table. See the Hook Summary for values used for all the various contexts. A query is made to get all the table items.
The query is restricted by the user selections from the view, filter, page, etc. This method outputs a single row by stepping through all the column headers. When a particular header comes up in the loop, it is matched to a case and the associated code is executed to output the actual table cell content. Hooking into this action enables you to output appropriate content in the correct part of the table.
You will need this to ensure your columns end up on the right table. One filter is to simply add the names of your custom columns, the other is used to generate the content of each table cell in your columns. Besides adding columns, there are other ways to alter what the list tables do. To add a custom column, you must first add its name to the array of column header names. Your callback is passed the current column header name array. The key can be any arbitrary unique string and the value is the actual column name that will appear in the table header.Managing WordPress users often requires recording custom information about each user and sometimes you might need to extend the default WordPress user options in order to create a customized profile of your users.
It provides a seamless interface to register custom fields and update the fields data for each user. Moreover, the custom fields are automatically added to the Users Insights filters, so you can filter your WordPress users by your custom fields data. The Custom Fields are registered as user meta fields.
This can be very beneficial if you already have some custom user meta fields applied to your users. In this case you will be able to use the already registered fields and load the saved data for each user. When creating a custom field, you can set the name of the field, key of the field and type of the field. The key of the field is the key that will be saved in the user meta table. If you would like to use already registered meta fields, you can just insert the existing user meta key into the field key.
The type of the field sets what type of data the field will store. At this point the supported field types are:. Once the field is created, you can later update it — you can modify all of its options, except the key. You can also delete the field if you no longer need it. All of the custom fields are automatically added to the profile data and would list any existing data:. You can edit each of the custom fields by clicking on the Edit icon.
The field input will be automatically determined by the selected field type. For example, for select fields there will be a dropdown to select from the preset options. Additionally, the user profile section provides some field management tools that can help you organize your custom fields.
You can easily reorder and hide the fields, as well as add section titles to group the fields. This feature can be especially useful when having a large number of custom fields. All of the registered custom user meta fields are available as columns in the Users Insights table.
Like the rest of the columns, you can sort the WordPress users list by any of these columns ascending or descending. All of the custom user meta fields are also available in the Users Insights filtersso you can easily filter your WordPress users by any of these fields.
How WordPress user data is stored in the database
The filter automatically detects the type of field and would provide conditions accordingly. And here is another example of filtering the users by their occupation — we want to find all the users whose job is related with marketing:. If you have a dropdown custom field, where you can select an option from a preset list, you can also filter your users based on this field. The filters allow you to find all users whose value match or does not match the selected value.The trick was creating a table in the WordPress database and being able to call to it from within my page templates.
Fortunately, it was actually pretty easy to do with a little research and testing. Once you have WordPress up and running the first step is creating the new table in our WordPress database. Add a new table for your site and give it a name. The quickest way to do this is to make a duplicate of your page. You can go ahead and create a new page and assign this template to it.
This will be our test page. You can add your own SQL query in there to get the desired results. For example to find Cute Girl Dog Names my query looks like this:. The next step to making this even better is using variables to make the queries. Then a single results page can run a variety of searches. The insert function includes the table name, an array of data to enter, and the format the data is in. The second array contains the variable type for each column inserted into the row.
Thanks a lot, this is exactly what I was looking for.
Sorry I missed this… basically just starting off giving my variables some values Toby, boy, etc. Thank you, very good tutorial. I tried it, but the output is always a empty Array… Could you help me….
Thanks for the article! I am just starting out with WordPress and need to query a table like this. A lot of people might do something similar and compromise the security of their website.
Very helpful post Kyle!Add Custom User Profile Fields to WordPress

I will go through an example of adding a custom field in the WP users table to display all post statuses and types at a glance. These days though, I play with the functions. Let me share some of my work in hopes to make your life simpler as well, even if just a little bit.
Many people are running multi-author sites. Other times, it is existing data that I want to pull in and see at a glance. I have exposed information such as last logged in date and time, whether the user has added AdSense to their account for revenue sharing, among other things.
Today though, I want to discuss something that I think just about anyone will find useful. On one WordPress site that I administer we have the need to know what the writers are up to in a sense. We would like to see, at a glance, how many posts they have matching each status. The code I offer below will work for any status, and any post type. So, even if you use custom post types and custom statuses for example, if using the Edit Flow WordPress pluginthis will work for you.
See the image below to get an idea of what I am referring to. I also want to make it very simple to access a list of each of the posts. Fortunately that is very simple, and it just requires passing an author ID and post status to an existing WordPress admin URL so that we can filter by those criteria.
First, I want to remove the default posts column from the Users table. They will simply login and the changes will be made, as if like magic. Just drop it before or after the posts unset command. Sometimes WordPress will make the column too wide unnecessarily. It may not matter… it will depend a lot on how many columns you will be working with.
If you find it needs to be smaller, then just add some CSS to the admin. You can use the code below for that, if, when you are done… you feel the column width needs adjusting. At this stage we can write a function that will return the post count based on post status, post type, and author id. This sexy bit of code returns a number based on the 3 parameters given. This code will call the previously created function as many times as we need it to.
You can add more to it if you have other statuses you want to display. Your email address will not be published. Save my name, email, and website in this browser for the next time I comment. Now, how do we do it? I hope that you find this useful. Comments 4 responses admin says:. September 1, at pm. Patricia says:. John says:. March 29, at pm. Tim H says:.

Over the course of years, WordPress has developed its own way of managing the data of its vast number of users. In this article, we are going to show you how WordPress stores this data in its database.
In WordPress, there are two tables in the database that store information about users. Two other tables are closely linked to these tables. You can take a quick look at how the WordPress user database tables are organized before proceeding, here. In the figure WP 4. You can also see the attributes of each table and how each of them is linked to the WordPress user database.
Do not let the symbols confuse you — they simply denote relationships between attributes of those tables. Only the most basic user information is stored here. Once they click the link in the e-mail, it is then matched with the key stored in this field. Now, if the key in the e-mail directly matches this key, the request is considered invalid.
The two keys should match only after the key from the email is hashed. This is how WordPress authenticates the password change requests of users. Note that passwords are stored in a hash form in WordPress as shown in the example above to ensure safety. The user meta table is often used by plugins to store custom user data. The meta value field does not apply any restrictions to the values that can be stored.
This means that you can store any types of values, including regular strings, numbers, dates or even PHP objects in a serialized format. If the record is a core WordPress field, there will be most likely a form field which you can find on your profile page to update its value.
The second way is to go deeper and do it programmatically. This means that you can use the functions that are already provided by WordPress, which can help you manage the metadata of users on your website of course, you will need to have permission to do this.

Any WordPress website out there is completely driven by its posts. You, as a blogger, may write numerous posts throughout the course of your lifetime, but you will never get better and grow as a writer if some form of feedback or criticism is not provided to you.
Comments are the instruments that allow your readers with an opportunity to communicate with you and provide those much-needed criticisms. Because of this, comments have now become just as important for a blog as anything else. Comments are linked to both users and posts. However, in case the commenter is not a WordPress user, the user id field defaults to 0.
In this article we learned how WordPress stores the records of its users. In addition to that, we also saw a list of the fields used to store all those records and gained an insight into how to manipulate them in WordPress.
