Summer Sales 20 Off for Piotnet Addons & Piotnet Forms

Tips and Tricks

During the operation time of Piotnet Forms, we recognized that users often set up improperly a form or be confused with the basic function’s setting.
So that we would like to list troubleshoots, our solutions or current limitations that you can encounter.


-Do not receive mail after submitting the form or require fields do not work.

Please make sure that you do not have the same Field ID in a form. If not, please send a ticket to our support email: After that, we could attend to this matter as soon as possible.

-Google Map does not work

In order for Google Map API to work, please make sure that the billing is enabled for your Cloud project. Please refer to this documentation here

-Special characters can not work properly with PDF Generator (xem lại)

In order to use normally your local language characters, please add a PDF font that is appropriate to your language.

Download your font here 

Then go to dashboard > Piotnet Forms > Custom font > add new > upload/add font.

Notice: just apply for TPF File.

-Don’t receive email

Please inspect your hosting company firstly, maybe your Website is not allowed to send the email.

You may verify with your hosting provider whether your site is permitted to send the email or not.

Inspect STPM setup or use an STPM plugin.

-Issue with same values

In many cases, you desire to use the same values for options to calculate.

For instance: you have a select field with 5 options below:


Your Form absolute will not work properly with 4 same issues as in the example.

 Solution: Implement alphabet characters right behind the same values. You can perform calculations with a letter appended to the numerical value.


Notice: This solution could apply to field types: Select, Radio, Image Select, Checkbox, and Select Autocomplete.

Tips and Tricks

-How to remove unfilled results in email?

There are two ways to achieve this goal:

Enable Remove Empty Form Input Fields Function in Other Options (Submit Button)


By default, all form fields are sent via shortcode: [all-fields]. Want to customize sent fields? Copy the shortcode that appears inside the field and paste it above. Enter this if you want to customize sent fields and remove line if field empty [field id=”your_field_id”][remove_line_if_field_empty]


-How do redirect data to another page?

You can enter this URL in the redirect within submit button: http://your site URL/?a=[field id=“abcd”] (if you have multiple fields, you can add “&”) In the form that you want to get data. You create a field and add a dynamic field value to get the value of the shortcode.

E.g. You want to get parameter value from URL {{request | parameter:utm_source}}

Current Limitations

-The PDF Generator does not work

At the moment, PDF Generator can perform basic manipulations when enabling the Custom Layout function, our Developer Squad has been enhancing this feature in near future.

When using the PDF Generator Custom Layout function, you may meet some unexpected cases if you do not follow our list below:

+ PDF just works fine with 1 page and A4 size when mapping fields (Custom Layout)

+ This function currently just works with versions under 1.6. Maybe your PDF Template File is not appropriate to the version of Piotnet’s Forms. You may check your version here and convert the PDF file to our required version by using this one

Notice: when you have a long form and do not have need to customize the position’s fields, All fields will be automatically ordered and broken page.
