This page explains the syntax of Contact Form 7‘s tag. If you are not familiar with basic usage of Contact Form 7, please see the plugin’s homepage.
Contact Form 7 uses “tags” for two purposes; one is for form content and the other is for mail (to, from and subject fields and message body). Tags for form content has different syntax from ones for mail.
Example of a tag used in form content:
[email* your-email 60/200 "your-email@example.com"]
Example of a tag used in mail:
[your-email]
As seen in above examples, a tag for form content generally has more complicated syntax and many options. In the rest of this page, I write mainly about the syntax and options of form content tag.

Base syntax of form content tag
A form content tag consists of a type, a name, options (optional) and values (optional).
Here is the syntax rule with my bogus BNF.
form content tag ="[" type name option* value* "]"type ="text" | "text*" | "email" | "email*" | "textarea" | "textarea*" | "select" | "checkbox" | "radio" | "captchac" | "captchar"name =- (same constraint as the
nameattribute of theinputelement)option =space [0-9A-Za-z:#_/-]+value =space ('"' string '"' | "'" string "'")
submit type tag is an exception. It doesn’t have name.
