I am using firebase for storing my app data but u all know firebase doesn’t accept special characters if any user enter special characters in textbox then how can I find special characters in textbox and how can I remove them.
Use this block:
You will get true if the mark you entered is in the text you entered (and if the mark is not found you will get: false)
It is works for only one special character in one time
You can attach some of these with: or
- specify all the special characters in a list (take a look what characters are not allowed in firebase)
- make a list of all those characters
- set text to “get list” or “is in list”
- set piece to the label / textbox which needs to get checked.
You can store all the values(which has special characters) in tags and then use this blocks to get the values.
Hope it helps.
