How can I validate user input?

User input and custom installer pages

You can validate user input adding a <validationActionList> to the parameter. For example, adding the following code to the 'installdir' parameter, will prevent the user from selecting a directory that contains a space.


<validationActionList>
   <throwError>
      <text>This directory path can not contain spaces</text>
      <ruleList>
         <compareText>
          <text>${installdir}</text>
          <logic>contains</logic>
          <value> </value>
         </compareText>
      </ruleList>
   </throwError>
</validationActionList>

This will create an installer environment variable called

protocol

that will contain the value of the text selected by the user. You can later refer to the content of the that variable using ${protocol}. In this example, if the user selects HTTP (unsecure), the variable protocol will contain the value http. Click here to download a sample project.xml file that integrates this functionality.
