Restrict content by user level

Chad Butler · May 16, 2014 ·

I have written code snippets before on how to restrict content by user level, but that particular code snippet is based on using categories as the user levels, with higher level users still being able to access lower level content. For example, Silver, Gold, and Platinum level users having access or not to categories of the same name.

But what if you have content that you need to block by level that is not necessarily in a category? Or what if you are using pages that need the same level of restriction.

Here is a code snippet that will allow you to assign a “level” to any content – post or page, and then assign a user level for the users. This example provides a working code snippet for applying a series of progressive levels (higher level users have access to lower level content). The example begins with three generically named levels, these can be renamed and expanded or contracted as needed.Continue Reading →

How to restrict categories to a defined user group

Chad Butler · Apr 26, 2014 ·

This concept is similar to the process outlined in How to add multiple user levels by category. However, the difference here is that we will restrict each category to a specific group (or level), but those users will not have access to the other categories.

In the other example, higher level users have access to lower level categories. In this example, each category is restricted to that specific group of users. Continue Reading →

Integrating Really Simple CAPTCHA

Chad Butler · Apr 25, 2014 ·

Really Simple CAPTCHA can be used with the WP-Members plugin in place of the default reCAPTCHA.

Note: This method of adding Really Simple CAPTCHA is no longer necessary as it is now supported directly within the plugin. Install and activate the Really Simple CAPTCHA plugin, enable it in the WP-Members options, and customize using the settings in the CAPTCHA tab. I am leaving this post active, however, as the code may be useful for developers that want more exact control over the Really Simple CAPTCHA display.

Confirm password at registration and have password meet specific criteria

Chad Butler · Apr 25, 2014 ·

I’ve shown other code snippets for similar things – password validation at registration and having a password meet specific criteria. However, the password requirements example was geared toward a setup that was requiring this when a user changes their password (they were not allowing it to be set at registration).

So here is an example that combines the two of these elements at registration. Continue Reading →

Multiple Selection Checkboxes

Chad Butler · Apr 22, 2014 ·

As of WP-Members 3.1.0, multiple selection checkbox support is an included feature in the plugin. That makes custom implementation such as described here unnecessary for most applications. I am leaving this post here however as there may continue to be users who (1) need a high level of customization that may utilize some or all of this kind of approach, and (2) for users who may not update to 3.1+ who need this support.

With the new wpmem_register_form_rows filter hook introduced in 2.9, the process of dealing with multiple selection checkboxes becomes far less complicated than previously.

The previous method involved adding each checkbox as a field, and then all of the extra code we needed to handle multiple fields as one both for storing the data, handling user updates, and also in emailing admin notifications.

But 2.9 allows us to filter the rows directly in the array of rows and insert the extra html we need for this. That means you only need to create one field in the fields manager which makes handling the data much easier on the backend. I’ve even made the code snippets nearly cut-and-paste. In most cases, you should only need to specify the name for the checkbox group and the labels/checked values. Continue Reading →
