How to filter WordPress post content

Sometimes there is a need to show or hide parts of a content based on who browses your website. With AAM 4.0 or higher you can archive this with the shortcode [aam context=”content”].

If you are copying and pasting shortcode from our website, make sure that correct quotes are preserved. Sometimes, depending on the operation system, quotes are not transferred correctly and you would have to manually change them.

For example if you want to exclude part of your page’s content for all visitors you can simply wrapped restricted content with following shortcode:

[aam hide="visitor"]...[/aam]

Another example is when you want to show for your subscribers something like “Please upgrade your account to the Contributor in order to read more”, then wrap the content with following shortcode:

[aam limit="subscriber" message="Please upgrade your account to the Contributor in order to read more"]...[/aam]

There are three attributes show, limit and hide to the shortcode that define content visibility. These attributes may contain user ID, role ID, IP address or reserved key all (means all users including visitors). You can find out user and role IDs on the AAM page as shown on the screenshot below.

For your information! The visibility attributes have priorities where the lowest priority is hide, then limit and finally show. This mean that the attribute with higher priority will overwrite attribute with lower priority. For example you may want to hide content for all users and visitors, however would like to display “Please upgrade your account to the Advanced role” and show full content for users with Advanced role. In this case you can wrap your content in the shorcode like this:
[aam hide=”all” limit=”subscriber” message=”Please upgrade your account to the Advanced role” show=”advanced”]…[/aam]

In case you want to filter content based on the user IP address, you can define either full IP address, mask or range or IP addresses. For example:, 192.123.* or 15- All kinds of range/mask permutations are allowed.

Shortcode attribute reference


Mandatory attribute that has to contain content value in order for AAM to filter content.


Comma-separated list of user IDs or role IDs to show wrapped content to. Use all to show for all users. Use visitor to show content to visitors.

Example. Show part of the content for all visitors.

[aam show="visitor"]...[/aam]


Comma-separated list of user IDs or role IDs to hide wrapped content to. Use all to hide for all users. Use visitor to hide content to visitors.

Example. Hide content for all subscribers and user John Smith with user ID 4 however show the content for all editor, contributors and administrators.

[aam hide="subscriber,4" show="editor,contributor,administrator"]...[/aam]


Comma-separated list of user IDs or role IDs to limited wrapped content to. Use all to limit for all users. The message attribute has to be defined when limit attribute is set because the defined message is used literally to replace limited content.

Example. Replace content with the message “Please sign up in order to read the remaining article” for all visitors.

[aam limit="visitor" message="Please sign up in order to read the remaining article"]...[/aam]


A custom message the wrapped content is replaced with when access is limited. See the limit attribute for more information.


Custom PHP callback function that will process the wrapped content. The callback function accepts one argument which is the instance of AAM_Shortcode_Strategy_Content class. The instance contains shortcode attributes and wrapped content.

Example. Process the wrapped content with custom callback function processContent.

[aam callback="CustomFilter::filterContent"]
class CustomFilter {

     * Filter post content
     * Based on user IP address, show different HTML content
     * @param AAM_Shortcode_Strategy_Content $shotcode
     * @access public
     * @return string
    public static function filterContent(AAM_Shortcode_Strategy_Content $shotcode) {
        $ip      = AAM_Core_Request::server('REMOTE_ADDR'); //AAM API: $_SERVER[REMOTE_ADDR]
        $content = $shotcode->getContent();
        if (preg_match('/^65\.', $ip)) {
            //loadPartial method simply loads specified relative file path
            $content = $this->loadPartial('usa.html');
        } elseif (preg_match('/^4\.', $ip)) {
            $content = $this->loadPartial('switzeland.html');
        return $content;
