Before and during development of a website or application, the audience for ProcessWire consists largely of web developers and web designers. Within this audience, ProcessWire is used as both a development tool and a CMS.
Post-development the audience changes to individuals that manage content for web sites and applications, who typically are not web designer/developers. This audience uses ProcessWire primarily as a CMS to manage content.
ProcessWire has been in active development since 2003. From 2003 to 2007 it was developed under the name Dictator CMS. From 2007-2010 it was developed as ProcessWire 1.x. ProcessWire became an open source community project in 2010 and it is currently developed as ProcessWire 2.x and 3.x.
ProcessWire has had 8 significant version releases, and more than 100 minor version releases since the first open source release. Version 3.0 released in September 2016 is the second major version release.
ProcessWire has active, global end-user and developer communities. These communities have translated ProcessWire from English into their native languages, including: Chinese, Croatian, Czech, Dutch, French, German, Greek, Hebrew, Hungarian, Italian, Japanese, Portuguese, Russian, Slovak, Spanish, Swedish, Turkish, Ukrainian and Vietnamese. The central hub of the ProcessWire communities are found in the developer support forums.
In November 2016 ProcessWire was awarded as CMS Critic's Best Small Business CMS.
Since January 2016 Envato Tuts+ has published several articles and tutorials on ProcessWire.
In January 2015 ProcessWire was awarded as CMS Critic's Best Free PHP CMS.
In December 2012 ProcessWire was awarded as CMS Critic's Best Free CMS.
ProcessWire is built around a page content tree (as opposed to a bucket system). The URL or path of each page is always reflective of its place in the hierarchy. One uses this same path to reference the page in the API. As a result, this connection of the path to the internal tree hierarchy defines the architecture of ProcessWire. Beyond the parent-child relationship implied by a content tree, ProcessWire supports relational one-to-one and one-to-many references between pages in the tree.
Templates in ProcessWire are a content type that contains one or more custom fields representing the definition of the content type. Every page in ProcessWire is assigned to a template which then represents the type of page. A template is typically shared among multiple pages. Templates also define access control, caching and other settings shared among pages using the template.
Templates optionally have an associated PHP file, referred to as the template-file. This file is executed whenever the URL for a page using the template is accessed. As a result, template-files are typically used for output purposes. The template-file is provided with several API variables, the most notable being the
$page API variable, which contains all the fields and content of the current page being viewed.
Template-files serve multiple contexts, depending on the application. ProcessWire's default web site profiles use template-files primarily for output of direct and dynamically generated HTML markup. Template-files may also be used as intermediate controllers between a model and a separate view. Because template-files are regular PHP files, they are able to call upon other web services or PHP applications where appropriate, without a separate parsing layer.
All fields in ProcessWire are custom fields defined by the user. A given field may be assigned to multiple templates, which in turn hold individual chunks of content for each page using that template. Every field has a type, referred to as the "fieldtype" (1 word), a type of plugin module. ProcessWire includes several fieldtype modules including those that support text, numbers, files, images, page references, URLs, email addresses, dates and comments. Additional fieldtype modules are installed as 3rd party modules.
