A number with a leading zero is considered a string, so you need to use a text form element for that. Numeric elements are strictly for numbers (in the mathematical sense) only.
I tried using text form but it also erases the zeros… 🙁
A text field won’t change the input, I just checked this and it works. Check to make sure your field is the right type, also you may need to reload the page if you are changing the form element type of a field.
Sorry, but It doesn’t work for me… zeros dissapear! I don’t know where is the error… I reload page. Any idea to solve it? Thank you.
OK, take a look at the configuration of your field. Make sure the Form Element is set to “Text-line” and save the configuration. Zeroes will not disappear if this field is configured correctly.
If you can post a link to the page that shows the problem I’ll take a look.
