<input type="text" />
and <input type="hidden" />
form fields, but version 4 finally introduces more:
get_bloginfo()
function, among others. See below for included shortcodes.
Don't see the shortcode you need on the list? You can write a custom one! Any shortcode that returns a string or numeric value can be used here. The included shortcodes just cover the most common scenarios, but DTX provides the flexibility for you to grab any value you have access to programmatically.
Dynamic Value
The bread and butter of this plugin, set a dynamic value! This field can take any shortcode, with two important provisions:
[
and ]
). So, instead of [CF7_GET key='value']
you would use CF7_GET key='value'
.CF7_GET key='value'
and not CF7_GET key="value"
'
%20
and other non-alphanumeric characters are converted.dtx_pageload
attribute to any dynamic form tag.
Many websites use caching plugins to optimize for performance. If your website caches the HTML of the form, then any dynamic form fields you have get their first calculated value cached alongside it. This becomes an issue if you're using DTX to pull values from a cookie or the current URL's query string.
This is best for dynamic form fields that:
readonly
attribute to the input form field. This feature is not available for dynamic hidden form tags.
Obfuscate Values for Enhanced Privacy
If you're pre-filling a form field with an email address, bots can scrape that value from the page and use it for spam. You can add an additional layer of protecting by obfuscating the value, which turns each character into it's ASCII code. To the human eye, it looks like the character it's supposed to be because browsers will render the ASCII code, but for bots, it won't look like an email address!
HOW TO USE IT
After installing and activating the plugin, you will have 2 new tag types to select from when creating or editing a Contact Form 7 form: the dynamic text field and dynamic hidden field. Most of the options in their tag generators will be familiar to Contact Form 7 users but there have been some upgrades.
How to Obfuscate Values
All of the shortcodes included with the DTX plugin allow the obfuscate
attribute that you can set to any truthy value to provide an additional layer of security for sensitive data.
The Contact Form 7 tag with obfuscation turned on would look like this: [dynamictext user_email "CF7_get_current_user key='user_email' obfuscate='on'"]
How to Enable Cache-Friendly Mode
All of the dynamic form tags can be enabled for processing on the frontend of the website, or the client-side, by adding the dtx_pageload
attribute to the Contact Form 7 form tag.
In the form editor of Contact Form 7, your form tag would look like: [dynamictext current_url dtx_pageload "CF7_URL"]
If using the tag generator, it's as simple as checking a box!
INCLUDED SHORTCODES
The plugin includes several shortcodes for use with the Dynamic Text Extension right out of the box. You can write your own as well—any self-closing shortcode will work, even with attributes!
Current URL or Part
Retrieve the current URL: CF7_URL
In the form editor of Contact Form 7, your form tag would look like: [dynamictext dynamicname "CF7_URL"]
Optional parameter: part
, which will return a parsed part of the URL. Valid values are host
, query
, and path
Host: Just the domain name and tld
[dynamictext host "CF7_URL part='host'"]
Query: The query string after the ?, if one exists
[dynamictext query "CF7_URL part='query'"]
Path: The URL path, for example, /contact, if one exists
[dynamictext path "CF7_URL part='path'"]
Learn more and see examples from the DTX Knowledge base.
Referrer URL
Get the referral URL, if it exists. Note that this is not necessarily reliable as not all browsers send this data.
CF7 Tag: [dynamictext dynamicname "CF7_referrer"]
Learn more and see examples from the DTX Knowledge base.
Current Page Variables
Retrieve information about the current page that the contact form is displayed on. Works great for use in templated areas like the site header, footer, widget, or sidebar! The shortcode works as follows:
Built-in shortcode: CF7_get_current_var
Required attribute: key
Possible values for key
include:
id
title
url
(an alias for CF7_URL
)slug
featured_image
terms
(an alias for CF7_get_taxonomy
)WP_POST
object, this acts as an alias for CF7_get_post_var
so those attributes work here as well.
For author pages, this acts as an alias for CF7_get_current_user
so those attributes work here as well.
In the form editor of Contact Form 7, your form tag's value could look like: CF7_get_current_var key='title'
And then the full form tag would be: [dynamictext dynamicname "CF7_get_current_var key='title'"]
Learn more and see examples from the DTX Knowledge base.
Post/Page Info
Retrieve information about the current post or page (must be for a WP_POST object) that the contact form is displayed on. The shortcode works as follows:
CF7_get_post_var key='title'
<-- retrieves the Post's Title
CF7_get_post_var key='slug'
<-- retrieves the Post's Slug
You can also retrieve any parameter from the global $post
object. Just set that as the key
value, for example post_date
The Contact Form 7 Tag would look like: [dynamictext dynamicname "CF7_get_post_var key='title'"]
Need to pull data from a different post/page? Not a problem! Just specify it's post ID like this:
Dynamic value: CF7_get_post_var key='title' post_id='245'
Contact Form 7 Tag: [dynamictext dynamicname "CF7_get_post_var key='title' post_id='245'"]
Learn more and see examples from the DTX Knowledge base.
Post Meta & Custom Fields
Retrieve custom fields from the current post/page. Just set the custom field as the key in the shortcode.
Note: You must add any meta keys that you want to allow access to to the allow list in your admin panel > Contact > Dynamic Text Extension > Meta Key Allow List. More Information
The dynamic value input becomes: CF7_get_custom_field key='my_custom_field'
And the tag looks like this: [dynamictext dynamicname "CF7_get_custom_field key='my_custom_field'"]
For the purposes of including an email address, you can obfuscate the custom field value by setting obfuscate='on' in the shortcode like this:
[dynamictext dynamicname "CF7_get_custom_field key='my_custom_field' obfuscate='on'"]
Learn more and see examples from the DTX Knowledge base.
Featured Images & Media Attachments
Retrieve the current post's featured image, the featured image of a different page, or any attachment from the Media Library with this shortcode!
The base shortcode is simply: CF7_get_attachment
which returns the absolute URL of the current page's featured image.
By setting the post_id
attribute to a post ID, you can get the featured image of another page.
By setting the id
attribute to an attachment ID, you can get the absolute URL of any image uploaded to your WordPress website.
By setting the size
attribute to any size registered on your website, you can get a specific image size.
Want to return the attachment ID instead of the URL? Also not a problem! Just set return='id'
in the shortcode.
Most of the optional attributes can be used at the same time. For example, if I wanted to retrieve the attachment ID of a featured image for a different post, then the dynamic text form tag would look like this:
[dynamictext input_name "CF7_get_attachment post_id='123' return='id'"]
If I wanted to get a specific image at a specific size, I can use this:
[dynamictext input_name "CF7_get_attachment id='123' size='thumbnail'"]
The only two attributes that can’t play together is id
and post_id
. If both are specified, it will get the attachment specified by id
and completely ignore the post_id
attribute. If neither are specified, then it looks to the current featured image assigned to the global $post
object.

Current User Info & User Meta
Get data about the current logged-in user.
Dynamic value: CF7_get_current_user key='user_displayname'
CF7 Tag: [dynamictext dynamicname "CF7_get_current_user"]
Note: You must add any user keys that you want to allow access to to the allow list in your admin panel > Contact > Dynamic Text Extension > User Data Key Allow List. More Information
Valid values for key
include:
ID
user_login
display_name
user_email
user_firstname
user_lastname
user_description
[dynamictext dynamicname "CF7_get_current_user key='user_email' obfuscate='on'"]
Learn more and see examples from the DTX Knowledge base.
Site/Blog Info
Want to grab some information from your blog like the URL or the site name? Use the CF7_bloginfo
shortcode. For example, to get the site's URL:
Enter the following into the "Dynamic Value" input: CF7_bloginfo show='url'
Your Content Form 7 Tag will look something like this: [dynamictext dynamicname "CF7_bloginfo show='url'"]
Your form's dynamicname text input will then be pre-populated with your site's URL
Learn more and see examples from the DTX Knowledge base.
Theme Options
Want to retrieve values from your active theme's Customizer? Now you can with the CF7_get_theme_option
shortcode.
Learn more and see examples from the DTX Knowledge base.
HTTP GET Variables
Want to use a variable from the PHP $_GET
array? Just use the CF7_GET
shortcode. For example, if you want to get the foo parameter from the url
http://mysite.com?foo=bar
Enter the following into the "Dynamic Value" input: CF7_GET key='foo'
Your Content Form 7 Tag will look something like this: [dynamictext dynamicname "CF7_GET key='foo'"]
Your form's dynamicname text input will then be pre-populated with the value of foo
, in this case, bar
Learn more and see examples from the DTX Knowledge base.
HTTP POST Variables
Grab variables from the PHP $_POST
array. The shortcode is much like the GET shortcode:
Dynamic value: CF7_POST key='foo'
Your Content Form 7 Tag will look something like this: [dynamictext dynamicname "CF7_POST key='foo'"]
Learn more and see examples from the DTX Knowledge base.
Cookie Values
If your WordPress website uses cookies, you might want to pull the value of a specific cookie into a form. You can do that with the CF7_get_cookie
shortcode. It only needs a key
attribute.
Dynamic value: CF7_get_cookie key='foo'
Your Content Form 7 Tag will look something like this: [dynamictext dynamicname "CF7_get_cookie key='foo'"]
Learn more and see examples from the DTX Knowledge base.
GUID
Generate a globally unique identifier (GUID) in a form field. This is a great utility shortcode for forms that need unique identifiers for support tickets, receipts, reference numbers, etc., without having to expose personally identifiable information (PII). This shortcode takes no parameters: CF7_guid
In the form editor of Contact Form 7, your form tag would look like: [dynamictext dynamicname "CF7_guid"]
