Simple Contact Form

Recommended Posts

Thank you very much for the quick reply!

#1 Ok, I'll do that.

#2 'action' => './#anchor' does work indeed, I should have thought of this.

BTW, I've just noticed a typo in the success message: "Your contact request has been send successfully!" => sent

Thanks for the great module! Maybe it should be renamed to Highly Customizable Contact Form ;):)

$emailMessage = file_get_contens('path/to/message.php'); // or include partial etc.
$modules->get('SimpleContactForm')->render($array('emailMessage' => $emailMessage));

I tried this, but I must be missing something here as the content of message.php is not interpreted by PHP but it is sent as a string literal, so I cannot get it to work :( What am I doing wrong?

Using twig the following does work:

{% set emailMessage %}{% include 'mails/recommend.twig' %}{% endset %}
{% set options = {
  'action': './#recommend',
  'emailMessage': emailMessage
} %}
{{modules.get('SimpleContactForm').render(options)}}
{# recommend.twig #}
...
{{ estate.title }}
{{ page.httpUrl }}
{% if input.scf_salutation == 1 %}xx{% elseif input.scf_salutation == 2 %}xx{% else %}xx{% endif %}
...

I thought using php should work the same.

I do not use twig, just plain php. In my message.php file if I have this for example:

<?php namespace ProcessWire;
echo "You have received a new contact form message";

That is what is sent, not just:
You have received a new contact form message

Actually this is what I expect, since file_get_contents simply reads the file, so I have the string, that's okay, but how is it going to be interpreted?

1)

$emailMessage = $page->title . ' test';
$content .= $modules->get('SimpleContactForm')->render(array('emailMessage' => $emailMessage));

2)

include('./mess.php');
$content .= $modules->get('SimpleContactForm')->render(array('emailMessage' => $emailMessage));

// mess.php
<?php namespace ProcessWire;

$emailMessage = $page->title . ' test2 ' . $input->post->fieldname;

Thank you! I'm testing them, and 1) obviously works, let's see the other two. I'll be back :)

I tested 1), 2) and 3).  They work all. :)

If you want to use file_get_contents, you need to pass an URL returning the content. Otherwise the code won't be interpreted.

Stackoverflow:

Quote

I suppose you want to get the content generated by PHP, if so use:

$Vdata = file_get_contents('http://YOUR_HOST/YOUR/FILE.php');

Otherwise if you want to get the source code of the PHP file, it's the same as a .txt file:

$Vdata = file_get_contents('path/to/YOUR/FILE.php');

I fixed the typo, thanks for the hint.

The translation string has been changed, some may need to translate it again!

It started pretty simple (for private use only). Then I did the "mistake" to put it on Github :lol:. But if you don't need something special, I think/hope it's still pretty easy.

Yes they do, however 3) with output buffering resulted in:

scf_enquirytype: 1
scf_name: Szabesz
Date: 2017-05-14 09:18:47

and I did not get my message. However, simple include works for me as expected. Here it is for reference if anyone is interested in getting the title of a selected Select Options Fieldtype:

<?php namespace ProcessWire;

// as per https://processwire.com/api/modules/select-options-fieldtype/#manipulating-options-on-a-page-from-the-api
// scf_enquirytype is a Select Options Fieldtype
$field = $fields->get('scf_enquirytype');
$all_options = $field->type->getOptions($field);

// $enquirytype stores the ID of the option selected
$enquirytype = $input->post->scf_enquirytype * 1;

$emailMessage = $enquirytype . "\n\n";
// WireArray is 0 indexed, while Select Options Fieldtype starts at 1, we account for this:
$emailMessage .= $all_options->eq($enquirytype - 1)->title . "\n";

BTW, thanks for the file_get_contents explanation, I've never used it instead on include, today I've learnt a few things again :)

I installed this module but it stays dead by all means.

First I installed it via the Modules interface in Processwire. Only two fields 'scf_name' and 'scf_email_adress' showed up in my Fields list. On the form also 'scf_website' appeared. Filling out a form gave an error message, probably because there was no message content. That went away when I entered a default text in the module interface. But no way to add the supposed fields. So I deleted the module via Processwire and removed the folder from my server.

Then I grabbed the zip file from Github and uploaded it to my server. This time no fields were created at all. I added an existing one in the module interface. It shows up alright, but no others except the dreaded 'scf_website' shows up – although it doesn't show up in my Fields list.

I'm using Processwire 3.0.62. Contact form is here amvk.be/contact/

@BFD Calendar Could you please explain what you did exactly? It doesn't matter whether the module is installed via ProcessWire Module Interface or via Github (unless you checkout develop branch). As the documentation says, the scf_website field is used as honey pot check to prevent spam. In module settings you could add any existing field or create new ones by entering the names (comma-separated). Per default no fields are added, because I do not know which fields you need ;) Furthermore: please have a look at the log file. If the form cannot be submitted, the reason will be found there.

@justb3a Ok, this makes things easier, guess I read some old documentation. I suppose you sent a form from city: whereever, that arrived.

But anyway, the scf_website field is still there.... and the other ones I added show up, but now the contact form doesn't pass the test. [FAILURE] Number of fields does not match.

And then I still haven't figured out how to format the fields on the form....

The scf_website field must be there! Again: this field is used for spam protection. Please read the belonging documentation as described above, all necessary informations are there:

Spam Protection: Hide honeypot field using CSS

Spam bots fill in automatically all form fields. By adding an invisible field you're able to trick the bots. The key to the honeypot technique is that the form only can be sent when the honeypot field remains empty otherwise it will be treated as spam.

The honeypot technique doesn't interfere with the user experience. It demands nothing extra of them like a captcha does. In fact, user won't even notice you're using it.

All that's required is a visually hidden form field. This form adds such a field named scf-website by default but you have to make sure to add a display: none; CSS rule on it.

If the fields does not match, you could have a look at your database. Table modules where class equals SimpleContactForm. Column data contains json, I guess the allFields value doesn't match anymore. Otherwise just reinstall the module and start with clean settings.

To format the fields, you can pass options to adapt HTML structure as well as class names. Unfortunately not everything can be achieved using this. For really special needs you have to hook into the field render function. To get an overview of what's possible, have a look at the documentation: How to overwrite classes and markup.

In my case I used UIkit 3 with LESS, so I could just style easily like this:

#contact-form input:extend(.uk-input) {}
#contact-form .field--error--message:extend(.uk-alert-danger) {}
#contact-form #wrap_Inputfield_submit:extend(.uk-width-1-1\@s) {}

#contact-form .FieldtypeTextarea:extend(.uk-textarea) {}
#contact-form #wrap_Inputfield_scf_message:extend(.uk-width-1-1\@s) {}

I uninstalled and deleted the module from the server, then reinstalled from the Modules interface and added fields etc. The contact.php template contains

	$scf = $modules->get('SimpleContactForm');

	$options = array(
	'emailAdd' => true,
	'emailAddMessage' => $input->scf_message,
	'emailAddMessage' => $input->scf_name,
	'emailAddMessage' => $input->scf_hometown,
	'emailAddReplyTo' => $input->scf_emailaddress,
	'emailAddTo' => $input->scf_email,
	'markup' => array(
    'list' => "<div {attrs}>{out}</div>",
    'item' => "<p {attrs}>{out}</p>"
    ),
	'classes' => array(
    'form' => 'form amvk_contact',
    'list' => 'list-item'
	)
	);

	echo $scf->render($options);

Now the form sends me two messages. The first one has the correct sender and subject (from the module interface) and correct reply address from the scf_emailaddress field in the form. The only content in the message is the scf_hometown information. The second message is all blank.

I do understand the honeypot technique. I just wonder why the field isn't invisible by default. "make sure to add a display: none; CSS rule on it" is probably simple when you know where to add that rule. I'm afraid I don't....

This is not how arrays work. Each key can ony exist once. EmailAddMessage is overwritten three times.

The field isn't visible by default, because I don't want to add inline styles. Just trigger the field in your .css file and add display:none; there.

@justb3a Speaking of invisible fields, validator.w3.org/nu reports:

Error: The for attribute of the label element must refer to a non-hidden form control.
date'>↩↩ <label class='form__item--label' for='scf-date'>Date</

But I need to hide this field too. What is your recommended solution?

Couple of questions...

Why use a label for a hidden field?

Is the date field to track when the user submits the form? If so, it is not necessary. You can set the date when you process the form.

But it won't affect the functionality, only the w3 validation.

Sure, the module works fine, and it supports spam protection based on the time the client uses to fill it in and to submit it, which is quite useful I think. It is just this label that should be somehow eliminated if possible. Since it is a ProcessWire form API field, I do not know how to achieve it.

I removed the date field label some days ago (@see Github issue). I didn't know that ProcessWire provides a way to skip the label. It's added to the develop branch, so it'll published with the next release! :)

      Wire Mail SMTP

      An extension to the new WireMail base class that uses SMTP-transport

      This module integrates EmailMessage, SMTP and SASL php-libraries from Manuel Lemos into ProcessWire. I use this continously evolved libraries for about 10 years now and there was never a reason or occasion not to do so. I use it nearly every day in my office for automated composing and sending personalized messages with attachments, requests for Disposition Notifications, etc. Also I have used it for sending personalized Bulkmails many times.

      The WireMailSmtp module extends the new email-related WireMail base class introduced in ProcessWire 2.4.1 (while this writing, the dev-branch only).
       
      Here are Ryans announcement.



      Current Version 0.2.6
      get it from the Modules Directory Install and Configure

      Download the module into your site/modules/ directory and install it.

      In the config page you fill in settings for the SMTP server and optionaly the (default) sender, like email address, name and signature.
      You can test the smtp settings directly there. If it says "SUCCESS! SMTP settings appear to work correctly." you are ready to start using it in templates, modules or bootstrap scripts.


      Usage Examples
      The simplest way to use it:
      $numSent = wireMail($to, $from, $subject, $textBody); $numSent = wireMail($to, '', $subject, $textBody); // or with a default sender emailaddress on config page This will send a plain text message to each recipient.
       
      You may also use the object oriented style:
      $mail = wireMail(); // calling an empty wireMail() returns a wireMail object $mail->to($toEmail, $toName); $mail->from = $yourEmailaddress; // if you don't have set a default sender in config // or if you want to override that $mail->subject($subject); $mail->body($textBody); $numSent = $mail->send(); Or chained, like everywhere in ProcessWire:
      $mail = wireMail(); $numSent = $mail->to($toEmail)->subject($subject)->body($textBody)->send(); Additionaly to the basics there are more options available with WireMailSmtp. The main difference compared to the WireMail BaseClass is the sendSingle option. With it you can set only one To-Recipient but additional CC-Recipients.
      $mail = wireMail(); $mail->sendSingle(true)->to($toEmail, $toName)->cc(array('person1@example.com', 'person2@example.com', 'person3@example.com')); $numSent = $mail->subject($subject)->body($textBody)->send(); The same as function call with options array:
      $options = array( 'sendSingle' => true, 'cc' => array('person1@example.com', 'person2@example.com', 'person3@example.com') ); $numSent = wireMail($to, '', $subject, $textBody, $options); There are methods to your disposal to check if you have the right WireMail-Class and if the SMTP-settings are working:
      $mail = wireMail(); if($mail->className != 'WireMailSmtp') { // Uups, wrong WireMail-Class: do something to inform the user and quit echo "<p>Couldn't get the right WireMail-Module (WireMailSmtp). found: {$mail->className}</p>"; return; } if(!$mail->testConnection()) { // Connection not working: echo "<p>Couldn't connect to the SMTP server. Please check the {$mail->className} modules config settings!</p>"; return; } Following are a ...


      List of all options and features


      testConnection () - returns true on success, false on failures


      sendSingle ( true | false ) - default is false

      sendBulk ( true | false ) - default is false, Set this to true if you have lots of recipients (50+)


      to ($recipients) - one emailaddress or array with multiple emailaddresses

      cc ($recipients) - only available with mode sendSingle, one emailaddress or array with multiple emailaddresses

      bcc ($recipients) - one emailaddress or array with multiple emailaddresses

       
      from = 'person@example.com' - emailaddress, can be set in module config (called Sender Emailaddress) but it can be overwritten here

      fromName = 'Name Surname' - optional, can be set in module config (called Sender Name) but it can be overwritten here


      priority (3) - 1 = Highest | 2 = High | 3 = Normal | 4 = Low | 5 = Lowest

      dispositionNotification () or notification () - request a Disposition Notification


      subject ($subject) - subject of the message

      body ($textBody) - use this one alone to create and send plainText emailmessages

      bodyHTML ($htmlBody) - use this to create a Multipart Alternative Emailmessage (containing a HTML-Part and a Plaintext-Part as fallback)

      addSignature ( true | false ) - the default-behave is selectable in config screen, this can be overridden here
      (only available if a signature is defined in the config screen)

      attachment ($filename, $alternativeBasename = "") - add attachment file, optionally alternative basename


      send () - send the message(s) and return number of successful sent messages


      getResult () - returns a dump (array) with all recipients (to, cc, bcc) and settings you have selected with the message, the message subject and body, and lists of successfull addresses and failed addresses,


      logActivity ($logmessage) - you may log success if you want

      logError ($logmessage) - you may log warnings, too. - Errors are logged automaticaly
       
       
      useSentLog (true | false) - intended for usage with e.g. third party newsletter modules - tells the send() method to make usage of the sentLog-methods - the following three sentLog methods are hookable, e.g. if you don't want log into files you may provide your own storage, or add additional functionality here

      sentLogReset ()  - starts a new LogSession - Best usage would be interactively once when setting up a new Newsletter

      sentLogGet ()  - is called automaticly within the send() method - returns an array containing all previously used emailaddresses

      sentLogAdd ($emailaddress)  - is called automaticly within the send() method

      Call ProcessWire API Functions Inside STRING
      Github Repo
      Current status : BETA
      Each called method must return string value !
      I added all functions, but not tested all. I focused page(), page()->render and field properties (label, description and notes). I also tested some basic pages() api calls.
      Your API calls must start with { and must end with }. For use multiple arguments inside functions, separate arguments with ~ char.
      NOTE If you pass directly arguments to api {page(title)}, this call will check for requestedApiCall()->get(arguments).
      USAGE

      This module corrects a few things that I find awkward about the "Add New Template" workflow in the PW admin. I opened a wishlist topic a while back because it would good to resolve some of these things in the core, but this module is a stopgap for now.
      Originally I was going to share these as a few standalone hooks, but decided to bundle them together in a configurable module instead. This module should be considered alpha until it has gone through some more testing.
      Add Template Enhancements
      Adds some efficiency enhancements when adding or cloning templates via admin.

      Features
      Derive template label from name: if you like to give each of your templates a label then this feature can save some time. When one or more new templates are added in admin a label is derived automatically from the name. There are options for underscore/hyphen replacement and capitalisation of the label. Edit template after add: when adding only a single template, the template is automatically opened for editing after it is added. Copy field contexts when cloning: this copies the field contexts (a.k.a. overrides such as column width, label and description) from the source template to the new template when using the "Duplicate/clone this template?" feature on the Advanced tab. Copy field contexts when duplicating fields: this copies the field contexts if you select the "Duplicate fields used by another template" option when adding a new template. Usage
      Install the Add Template Enhancements module.
      Configure the module settings according to what suits you.

      Hi,
      I've put in a support request (as a followup on an existing one) for this but it's nearly 10pm Ryan's time, so I thought I'd ask on here just in case someone can help...
      Yesterday we purchased ProDrafts, but I couldn't get the key to validate. Every time I hit submit on the module settings screen the key would be removed from the field I entered it in, and then it would complain about the missing value. I put in a support request and Ryan responded last night. It turned out it was because we're behind a proxy/firewall. He gave me a fix to get around that issue - some code to go into admin.php. I put that code in and saved admin.php, but now I can't even get into our admin anymore!
      (Just to clarify, I took the code back out and saved admin.php but that made no difference. It's definitely not the new code causing the error.)
      The errors relate to a lack of permission on the ProDrafts module (see attached screenshot). We do have a key, but evidently the code Ryan gave me to add the key in via admin.php isn't taking effect before the error is thrown...?
      I tried removing the ProDrafts directory from the modules directory, but that hasn't helped.
      Is there a hook I can put in somewhere to tell it not to load ProDrafts at all, or not check the permissions? Or is there some way to manually uninstall it from the file system?
      Thanks!

      I just made a textformatter module that allows you to insert dummy content (lorem ipsum style) in text fields via shortcodes.
      Usage is simple - just type for example [dc3] into a textarea with this textformatter applied (plain textarea or CKEditor) and it will be replaced at runtime by 3 paragraphs of dummy content. It can also be used to populate text fields (for headings etc) using e.g. [dc4w]. This will produce 4 words (rather than paragraphs) at runtime.
      The actual content comes from an included 'dummytext.txt' file containing 50 paragraphs of 'Lorem ipsum' from lipsum.com. The 50 paragraphs is arbitrary - it could be 10 or 100 or anything in between, and the contents of that file can be changed for your own filler text if you wish.
      The slightly clever bit is that for any given page, the same content will be returned for the same tag, but the more paragraphs available in 'dummytext.txt', the less likely it is that two pages will get the same content (very roughly speaking - it's actually based on the page ID) so content selection is determinate rather than random, even though only the tags are saved to the db.
      Update
      Tags now work like this -
