Customer’s Love

“My client websites got over 300 spam emails daily. I tried Google ReCaptcha 3 and that didn’t work on low traffic sites. ReCaptcha 2 didn’t stop all the spam either. I looked at many options, including SAAS, but didn’t like the prospect of paying monthly. In the end I used Iris with its ReCaptcha 2 feature. The Iris has completely stopped the spam. I’ve had NO spam thereafter. It is by far the most cost-effective solution. In addition, Vincy followed up on all emails I sent and has provided great customer service!”

Comments to “Contact Form – Iris”

  • Doug says:

    I am running a small community website. If I buy this, will you help me to install it in my website?

    • Vincy says:

      Yes Doug, definitely. When you make the purchase, you are also buying my support for installation :-)

      I will stand by and make sure that this contact form goes live in your website.

  • Liam says:

    Do I need email SMTP server to use this contact form?

    • Vincy says:

      This contact form works via three different options i) email SMTP server ii) PHP’s mail() iii) sendmail. You should have either of the three options. SMTP is the best as it provides you more control over the email. PHP’s mail() is the simplest to use provided your web server is configured and supports.

      In summary, this PHP contact form provides you multiple options. You can use whichever is convenient for you.

  • Willie says:

    I bought this contact form, everything is working good. But, large attachments are not working. My customers will send me floor plans etc and it should allow to use large attachments. Can you fix it?

    • Vincy says:

      Thank you for the purchase Willie.

      Files attachment size limit is intentional.

      In the configuration file Config.php, there is a size limit defined. Users will not be able to send attachments beyond that limit. You need to increase that.

  • Pront says:

    My website is done in Bootstrap, will this contact form work in it?

    • Vincy says:

      Yes Pront. This contact form is compatible with Bootstrap theme. The styles used in here will not make any conflict with your existing Bootstrap styles.

  • Brad says:

    Vincy, I purchased this contact form yesterday and it is working. I want to change it as an application form by adding more fields. Can you help me?

    • Vincy says:

      Hello Brad,

      Thank you for the purchase. Sure, I will help you to customize the contact form and change it to an application form to suit your need.

      There is a step by step procedure with an example in the “readme.txt” documentation available as part of the bundle. Refer section 5.1 to know about how to add a field. You can just do it yourself in minutes.

      If you are still not able to add fields, please email me the details and I will do it for you. Thanks.

  • heinrich weber says:

    Will this work in mobiles?

    • Vincy says:

      Hi Heinrich Weber,

      Yes definitely. The complete contact form is designed responsively. This will work smoothly in mobile, tablet, laptop, desktop and for any viewports. Guaranteed! :-)

  • Danny Trombe says:

    Will this work with my WordPress?

  • Alex Slay says:

    I wish to have multiple file attachments, is it possible?

    • Vincy says:

      Hi Alex,

      Iris contact form comes with core level support for attachments. It also has (dynamic) add-more support for the attachment field. The end-user can choose to add as many attachments as he wants.

      As a admin, you have control via config on the maximum attachment size and the filetypes.

      I assure you that, the support for file attachment in this contact form is the best ever you will get in Internet. Try the demo and see it for yourself.

  • Jonas says:

    Does this supports animations? I want the contact form to shake when the user submits. Is it possible?

    • Vincy says:

      Hi Jonas,

      The product does not come with such animations. Actually it is a bad practice in the user experience front to have such shaking animation, even if there is an error.

      Having said the above, if you definitely wish to have that, I can code that as a custom service exclusively for you. Please check the live demo to get a full feel of the product.

  • Leo says:

    Can the contact form input be limited to a specific language?

    • Vincy says:


      Actually the intention is to support multi-language and as many as language possible. It is other way around. So I have not restricted the user input to any particular language.

      If you require this as a special case, then I can do it as a custom service exclusively for you.

  • sim ola says:

    Hi Vincy,

    I am kinda lost as to how to make this work for my site, can you help?

    • Vincy says:

      Hi Sim ola,

      Thank you for the purchase. There is a file “readme.txt” that is bundled with the product you have got. Please go through it as it has detailed documentation to help you setup. Still if you find it difficult, send an email to me with details on your setup and I will take it up.

  • Enrico says:

    Hello, I tried the “Live Preview” (standard config with self copy), and there appears to be no option to delete the first attached file before sending, only for the second and additional attachments…

    • Vincy says:

      Thank you Enrico for informing this. I will add a ‘remove’ option for the first attachment also. This will be done within a week and a new update will be released. Thank you.

  • Valeria says:

    Could you kindly tell me if Iris can be included as a simple contact form at the bottom of some of my pages (just HTML and PHP, no WP, js or similar which I’m trying to avoid as much as possible). Thank you

    • Vincy says:

      Hi Valeria,

      Yes, the Iris contact form can be included in any place of a PHP file. For example, if you already have a webpage and then you want to insert the Iris contact form in some position of that page. It is absolutely possible. WP is not required, just plain PHP is sufficient.

  • Bedford says:

    Hello, your forms look good and simple to install. However, I have not purchased but would like to. Here is my question: How many websites can one use your contact forms? Any limitations? Thanks. Bedford

    • Vincy says:

      Hi Bedford,

      Good day!

      If you want to use the form in one page, then you can buy the “Individual License”. If you wish to use in multiple pages, then you need to buy the “Company License”. Please feel free to email me or comment and I will respond.

  • Victor says:

    Thank you for this great invention.
    Since Iris can be used as a web survey form, I should be able to download the database or CSV file, is it possible.

    • Vincy says:

      Hi Victor,

      The information can be stored in the database. You can download the information via the database client as CSV or SQL as per your wish.

  • Denise Jeffers says:

    Good afternoon
    If I buy this can I get setup assistance and use on multiple client sites?

    • Vincy says:

      Hi Denise,

      Good day!

      You can use the contact form on multiple pages or sites. You need to buy the “Company License”.

  • Tyrell says:

    Does this form support drag and drop feature?

    • Vincy says:

      Hi Tyrell,

      I assume that you are looking for drag and drop feature for uploading attachments. I have designed a custom component with minimalism as objective. Please have a look at it in the demo and you may like it.

  • Naveen says:

    Can I save the contact data in the database.
    if there are multiple contact forms in the site can I configure which contact form confirmation goest to which admin?
    like which contact form mail goes to support, info, technical etc

    • Vincy says:

      Hi Naveen,

      Yes, there is an option available to save the information in a database. It is optional and can be switched on via the config file. Yes, multiple contact forms can be mapped to different recipient admins. Since you need to host multiple forms, you need to buy Company License.

  • Catherine Glover says:

    Hi Vincy
    Your product looks as if it is just what I need. I work (free-lance) for a History Society (non-profit). There is just one developer (me) and I am wondering which licence I need.

    Also, you don’t mention anywhere how the target email address(es) are hidden from spammers. You mention many other security issues of which I was only dimly aware, so I am confident that Iris hides the target email addresses securely but I would like to understand how.
    Best wishes

    • Vincy says:

      Hi Catherine,

      You can buy “Individual License” that should be sufficient. If you are going to the use the form in multiple pages, then you will need “Company License”. The target email addresses are hidden buried in a PHP config file. It is not revealed to any public users or spammers. The speciality of Iris contact form is spam protection and security. I assure you, it is safe from spammers.

  • Walt Poff says:

    Hello Vincy, I am thinking of buying the responsive version of your response form. My website is hosted on a godaddy site. I have deluxe Linux hosting with cPanel. I have looked at many form handlers and tried a few with no success. Tech support from godaddy is terrible so I will need help setting it up and getting it to work. Do you help with the install if I purchase? I want the form results to post to a MySQL db and send me an email. Let me know if I can count on help from you until it is up and running properly on my website?

    • Vincy says:

      Hi Walt,

      Yes, of course I will help you setup the form in your website. This Iris contact form works good in many Godaddy hosted sites. The option to store the information in database also works good. I will help you setup, be assured and go ahead :-)

  • Veeresh says:

    I have two form on my website, one on careers page and other on Contact page. Can I use this on both the forms with one license.?

  • Robert says:

    How to open the form in a popup ?

    • Vincy says:

      Hi Robert,

      It is possible to use this contact form as a popup. It will be given as a feature example in the next release. If you have already bought the product, please email me with your order reference and I will help you out.

  • Nina says:

    Hello Vincy,

    Love your article and the time you’ve taken to go into such detailing. Wow simply amazing! Haven’t seen anything like this. THANK YOU. I’d like to purchase licensing for my site and my clients websites. Which license do I purchase? I see it comes with 12 months support, is this a onetime fee?

    In Kind Regards,

    • Vincy says:

      Hi Nina,

      Thank you so much. You should buy the “Company License” if you intend to use it in multiple websites.

  • Werner says:

    Hello, I need to add additional form fields as select boxes for numbers of day, year, month, hours, seconds. Is this possible in an easy way? I want to have name and surname in one row, then date and time in second row below and same size as row above, in third line one single text input same size as the two rows already mentioned above.
    Kind Regards, Werner

    • Vincy says:

      Hi Werner,
      In the latest release (Version 3.2.1), I am giving an additional bundle “minimal” as part of the package. This is a simple and minimalist version of the product. The main purpose is to enable easier customization for the form. All you need to do is just two steps, 1) add the field you need in the UI and 2) get that field in email-template. That’s it. For adding the field in UI, it is just simple plain HTML. You need to know HTML to the extent of adding input fields. That is sufficient to customize the form. This is the easiest it can get for a developer ;-)

  • Andre says:

    Can this be integrated in my Bootstrap website?

    • Vincy says:

      Hi Andre,

      Yes. This Iris contact form has a separate dedicated UI for Bootstrap framework. You can switch the UI as per your preference. You can use Iris with or without Bootstrap easily.

  • Luigi says:

    As our new server will use PHP 7.4, I need to replace our existing trilingual secure contact form (French, English, Spanish).
    I have a few questions:
    Is Iris compatible PHP 7.4?
    Can Iris be configured to keep sending data to our existing PHP database?
    Can Iris be configured to report the IP address of the sender (our existing secure contact form does)?
    Awaiting your reply,

    • Vincy says:

      Hi Luigi,

      Yes, Iris is compatible with PHP 7.4. Iris is compatible with PHP 5.6 or above till the latest PHP 8.x
      Yes, Iris can be configured to send the submitted data to a database and store each submission as records.
      Yes, Iris can be configured to report the IP address of the sender. It is also GDPR compliant.

  • Duncan says:

    Does the latest version of the form work with PHP 8, please?
