Input Validation

Form fields added from ' control palette have built-in validation rules.  The table below details the default validation for each control type in ' palette. Patterns added to a control change the defaults.

([1-9]|[1-3][0-9]|4[0-2])

Patterns i.e. regular expressions take into consideration each character that is entered instead of the whole value that is entered. Here is the explanation for the pattern shown above:

• [1-9] – means any number between one and nine will satisfy the pattern. So this covers the range of numbers between 0 and 9.
• | - OR operator   
• [1-3][0-9] – means first digit can be between 1 and 3 and second digit can be between 0 and 8 to satisfy the pattern. So this covers the range of numbers between 10 and 39.
• | - OR operator
• 4[0-2] – means first digit can be 4 and second digit can be 0 or 1 or 2 to satisfy this pattern. So this covers the range of numbers between 40 to 42

Numbers with commas

' default number control supports digits followed by an optional decimal point and multiple decimal places. Suppose instead you want to allow numbers containing commas and optionally starting with a '$' and only up to 2 decimal places. For example: $1,000.50 2,500. But also to allow numbers without the comma such as $1000. To do this:

<xsd:simpleType name="emailType">       
          <xsd:restriction base="xsd:string">        
                  <xsd:pattern value="[a-zA-Z0-9\-_][a-zA-Z0-9\-\+_]*(\.[a-zA-Z0-9\-\+_]+)*@([a-zA-Z0-9\-_]+\.)+[a-zA-Z]{2,6}"/>         
          </xsd:restriction>    
</xsd:simpleType>

Phone pattern

Lets say you would like to change the phone control validation from the ' current built-in pattern. Cloud customers must apply Patterns to a text control while in-house customers have two options

1. Apply patterns to a control - Like other control properties, the pattern property will not need to be redone when you upgrade .
2. Modify the built-in values in the types.xsd file. Be aware that if you modify the types.xsd file, you will have to make this change each time you perform a  upgrade or apply a  patch.

Apply a Pattern to a Control for a Phone Number

If you are using  Online, you will not have access to types.xsd. Both cloud and in-house customers, can override the pattern in the phone control by setting its pattern property. You can only restrict a built-in pattern (such as the phone control) but not change the pattern via the pattern property. For example you can add the pattern 203-\d{3}-\d{4}.  Now all phone numbers must start with area code 203.

A pattern such as ##-####-#### or ####-###-### is not a simple restriction. To impose validation against this pattern you must start with a Text control rather than a Phone control

1. Drag a Text control to your form
2. Add your pattern to the Text control's pattern property: \d{2}-\d{4}-\d{4} or \d{4}-\d{3}-\d{3}
3. Change the error message and help properties to assist the user in understanding the required pattern

Modify the types.xsd file

frevvo OEM partners may choose this method when customizing . The built-in values are shown in the image below:

...

1. Stop  if it is running. 
2. Unpack the frevvo.war file to a temporary location of your choice: e.g. c:\tmp\frevvo-war.
3. Edit c:\tmp\frevvo-war\WEB-INF\data\users\types.xsd,
4. Change the element phoneType as shown in the code block below: Save the changes to the types.xsd file. 

5. Rezip all the files in the c:\tmp\frevvo-war directory, even the ones you did not edit.

6. Zip will often give your zipfile a .zip extension. Make sure you change this to a .war extension. 

7. Copy the updated frevvo.war file to <frevvo installdir>/tomcat/webapps.
8. Restart your  form server. Now all your phone controls will validate against this pattern.
   
   

<xsd:simpleType name="phoneType">     
    <xsd:restriction base="xsd:string">         
        <xsd:pattern value="\d{2}-\d{4}-\d{4}"/>         
        <xsd:pattern value="\d{4}-\d{3}-\d{3}"/>
    </xsd:restriction> 
</xsd:simpleType>
