Simple Forms

The "Simple Forms" extension allows you to insert forms into your templates. Use it by simply placing the following in your template, with the name of the form to insert:

{{ simpleform('formname') }}

With SimpleForms you create forms, by defining them in the app/extensions/simpleforms.bolt.yml-file. The file has some general settings, plus a section with fields for each different form.

Installation

The easiest way to install this extension is to go to "View/Install extensions" in the "Extra" menu in your bolt install, type "SimpleForms" into the search box and follow the instructions.

License

Simple Forms is released under the open source MIT-license.

General settings

  • stylesheet: assets/simpleforms.css - The CSS to display the forms with. If you want to modify the CSS, you should copy the file to your theme/ folder, and modify it there. Any changes in the file in the distribution might be overwritten after an update to the extension.
  • template: assets/simpleforms_form.twig - The Twig template to display the forms with. If you want to modify the HTML, you should copy the file to your theme/ folder, and modify it there. Any changes in the file in the distribution might be overwritten after an update to the extension. This file uses the Symfony Forms component.
  • mail_template: assets/simpleforms_mail.twig - The Twig template to format the emails with. If you want to modify the HTML, you should copy the file to your theme/ folder, and modify it there. Any changes in the file in the distribution might be overwritten after an update to the extension.
  • message_ok: ... - The message to display when the form is correctly filled out and was sent to the recipient.
  • message_error: ... - The message to display when there's an error in one of the form fields.
  • message_technical: ... - The message to display when there's a technical error preventing the sending of the email. Most likely this is caused because Swiftmailer can't send the email. Check the Swiftmailer settings in the global config.yml if this message is shown.
  • redirect_on_ok: ... - Instead of simply displaying a message when the form is 'OK', you can also redirect to a different page on the site, for a more extended message after submitting the form. The value should be a contenttype/id or contenttype/slug pair. For example: entry/1 or page/thank-you.
  • button_text: Send - Default text on the 'send' button in the forms.
  • recipient_cc_email: info@example.com - Use this value to set a global cc email address, this email address will receive a copy of all emails sent with simpleforms.
  • recipient_cc_name: Info - Use this as the display name for the cc email address.
  • recipient_bcc_email: info@example.com - Use this value to set a global bcc email address, this email address will receive a blind copy of all emails sent with simpleforms - this value does not have a display name.
  • testmode: true - Sets a global testmode, you can use this to for development if you do not want other people to be bothered by endless testing emails. If you set this value to true all email will be sent to the testmode_recipient and all other recipient and cc addresses will be ignored. The default value is false.
  • debugmode: true - Sets a global debugmode, the form will output a lot of internal debug information you can use this to for development
  • testmode_recipient: info@example.com - The email where all test emails should go.

Tip: If you want to copy one of the template files, you should remember to leave out the assets/ part. For instance, if you copy simpleforms_form.twig to theme/base-2013/my_form.twig, the corresponding line in config.yml should be:

template: my_form.twig

Configuring forms

You can define multiple forms, where each form has its own section in the config.yml file. The default file has two forms defined, namely 'contact' and 'demo'. The structure of a form definition is as follows:

myformname:
  recipient_email: info@example.org
  recipient_name: Info
  mail_subject: "[Simpleforms] Contact from site"
  fields:
    fieldname:
      type: ..
      ..
    fieldname:
      type: ..
      ..
  button_text: Send the Demo form!

Each form has a name, which is used to insert the correct form in your templates. For example, if you've named your form myformname, as in the example above, you can insert the form in your templates using {{ simpleform('myformname') }}. Use the recipient_email and recipient_info fields to set the recipients of the emails. Use the mail_subject value to set the subject of the confirmation emails. The optional button_text can be used to override the global setting for the text on the 'send' button.

Each of the 'General settings' mentioned above can be overridden for a specific form. So, you can create forms that use different templates and different messages.

The fields of the form are defined in the fields-array. Every field is defined by its name, with its options. For example:

    subject:
      type: text
      class: wide
      required: true
      label: Subject of your message
      placeholder: Just a quick message ..

Make sure the name (in this example subject) is unique to the form. Each of the different fieldtypes has a few options to modify the functionality or appearance:

  • class - The class is passed in the rendered HTML, so it can be used to style the form elements.
  • required - Whether or not the field is required to be filled in. If omitted, defaults to false.
  • label - The textual description of the field on the website, for when the name of the field isn't descriptive enough.
  • placeholder - An optional placeholder for the field.
  • value - The default value of the fiels in the form.
  • allow_override - If set to true, it's possible to override the value in this field using a GET parameter in the URL. For example, if your form has a field title, you can override it using /page/contact/?title=This+is+the+title. The form takes care of escaping the input, to prevent XSS.
  • read_only - Set the field to readonly in the generated HTML. (yes, we're aware of the inconsistency between 'read_only' and 'readonly'. 'read_only' is the name of the option in Symfony's Form component, while 'readonly' is the name of the attribute in the generated HTML)
  • prefix - Add a snippet of HTML to output before the <div> with the field's row.
  • postfix - Add a snippet of HTML to output after the <div> with the field's row. You can use these attributes to insert labels, headings or to divide the form in <fieldset>'s.
  • use_as - Only for email fields, you can use to_email, from_email, cc_email or bcc_email to use the entered email as an extra address.
  • use_with: fieldname - An optional name for an email field. Use this to reference another field, that will be used to display the name of the person, used in the use_as. Doing this, you can make emails with proper recipients, that will be shown as Example person <info@example.org>. See the 'Email input with extra recipient' example below.
  • minlength - Add HTML5 form validation minimum length input attribute. Browsers that recognize HTML5 form validation will not except any input shorter than your entered value. Example: <input type="text" minlength="5"
  • maxlength - Add HTML5 form validation maxlength to your input attribute. Browsers that recognize HTML5 form validation will not except any input longer than your entered value. Example: <input type="text" maxlength="25"
  • autofocus HTML5 autofocus attribute. On page render the input with autofocus="on" will be highlighted. Options are autofocus: on or autofocus: off. Only one form element can have the autofocus attribute. It cannot be applied if the type is hidden.
  • expanded: true Attribute for choice elements, use this in combination with multiple and required to make select boxes, radio groups or checkbox groups
  • multiple: true Attribute for choice elements, use this in combination with expanded and required to make select boxes, radio groups or checkbox groups
  • autocomplete HTML5 form attribute that turns the in browser autocomplete function on or off. This is ignored if the input type is set to hidden.
    • off: must explicitly enter a value into this field for every use. the browser does not automatically complete the entry.
    • on: The browser can automatically complete the value based on values that the user has entered during previous uses.
  • pattern A JavaScript regular expression to check the input field against. This attribute applies to fields with a type of text, search, tel, url or email. Example alphanumeric: <input type="text" pattern="^[a-zA-Z0-9]+" />

The different fieldtypes are as follows, with a short example outlining the specific options for that field. Remember you can also use the basic options as well.

Standard text input:

name:
  type: text

Email input:

email:
  type: email

Text area (multi line input):

message:
  type: textarea

Select box (pulldown):

favorite:
  type: choice
  multiple: false
  choices: [ Kittens, Puppies, Penguins, Koala bears, "I don't like animals" ]

Radio buttons:

favorite:
  type: choice
  expanded: true
  required: true
  multiple: false
  choices: [ Kittens, Puppies, Penguins, Koala bears, "I don't like animals" ]

Checkboxes:

favorite:
  type: choice
  expanded: true
  required: false
  multiple: true
  choices: [ Kittens, Puppies, Penguins, Koala bears, "I don't like animals" ]

Checkbox:

option1:
  type: checkbox

Date input:

some_date:
  type: date
  format: "Y-m-d"

The format option is used for formatting the date in the emails. You can use the options that are available in PHP's date() function. See the documentation for details.

Using ReCaptcha field:

To protect your forms from spam-bots, you can enable the ReCaptcha service. This lets the visitors type out two words or numbers from a picture, to prove that they're human. To enable ReCaptcha, simply enable/fill all the recaptcha_ fields in config.yml. If you don't have a private/public keypair yet, go to this URL to create them.

Overriding values

Override values from the template

{{ simpleform('formname', { 'somefield' : somevalue } ) }}

This will prefill the field named somefield with somevalue. This is always available but it will be overridden by $_GET['somefield'] if allow_override: true is set for somefield.

Email input with extra recipient:

If you want to send a copy of the an email address the visitor entered, you can use the use_as and use_with options for email and text fields.

You can define as many email fields as you like and the addresses will be used, you need to add the use_with option for each field if you want nice display names.

recipient:
  type: email
  use_as: to_email|from_email|cc_email|bcc_email
  use_with: another_fieldname
another_fieldname:
  type: text
  label: "The name of the person this email is sent to"

Special log fields

There are a few field types for logging ip-addresses and other user values

Remote address

log_ip:
  type: ip

This will fetch the remote IP address and even try to look through proxies for it.

Remote host

log_remotehost:
  type: remotehost

This will attempt to lookup the remote hostname, or just give you an empty string.

Remote user agent

log_useragent:
  type: useragent

This will return the browser's user agent string.

Timestamp

log_timestamp:
  type: timestamp

This returns the current timestamp.
