  • 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.
