This feature provides a simple way to ensure that a ticket will always have a Subject. It is implemented via JavaScript and so requires that JavaScript be enabled in browsers (or at least in the browsers of people who leave the subject blank). As such, this may not be the best approach to take for some sites, as it does not block creation of tickets with empty subjects on the server side. You can easily adapt this to validate other form elements. This patch was created against 3.6.3 source.

The following files will be patched (where <rt-root> is the root RT directory, e.g. /opt/rt3):

  • <rt-root>/share/html/index.html
  • <rt-root>/share/html/Elements/Header
  • [=<rt-root>/share/html/Elements/QuickCreate]
  • <rt-root>/share/html/Elements/Submit
  • [=<rt-root>/share/html/SelfService/Create.html]
  • <rt-root>/share/html/Ticket/Create.html
  • <rt-root>/share/html/Ticket/Modify.html
  • [=<rt-root>/share/html/Ticket/ModifyAll.html]

For each of the above files that have not already been patched, you must:

  1. recreate the directory structure under <rt-root>/local (e.g. [=<rt-root>/local/html/SelfService])
  2. copy the file from <rt-root>/share/whatever to <rt-root>/local/whatever

After that, you need to:

  1. create the file <rt-root>/subject.diff, with the contents shown below
  2. apply the patch (assuming <rt-root> == /opt/rt3):
$ cd /opt/rt3
$ patch -p0 <subject.diff

<rt-root>/subject.diff

There's basically a couple of parts to this patch. The most important is at the very top of the diff, the one that modifies local/html/Elements/Header, and it adds in a block of code that sticks the <SCRIPT> tag into the HTML, if it's passed into the Mason Element. This is going to be the function definition of the code that actually checks your input. You have to provide this function definition, and it would look something like this:

function checkform( form ) {
   if (form.Subject.value == "") {
      alert( "You must enter a subject." );
      form.Subject.focus();
      return false;
   }

   return true;
}

The next change is to local/html/Elements/Submit to tell it to call the function just described. Again, you have to provide the code, and it will look like this:

<& /Elements/Submit,
   Label => loc("Create ticket"),
   JavaScript => q(onClick="return checkform(document.TicketCreate);")
&>

Next, find a FORM and a form element that you want to add a check to. Modify the FORM to give it a name if it doesn't have one already, e.g. <form action="Display.html" method="post" enctype="multipart/form-data" name="TicketCreate">

The input field you want to check should have a name; note it (e.g. Subject). You will need that name for the checkform function.

The Elements/Header for that page should be modified to pass in the checkform function described above:

JavaScript => q(function checkform( form ) {
   if (form.Subject.value == "") {
      alert( "You must enter a subject." );
      form.Subject.focus();
      return false;
   }

   return true;
}

Next find Submit button for that form and modify it as directed above in the Elements/Submit section. Some forms don't use Elements/Submit, and you would have to code up the input manually, like this:

<input type="submit" class="button" value="<%loc('Create')%>" onClick="return checkform(document.QuickCreate);" />

That's all there is to it! If you have any problems with the patch, please let me know -- JoeCasadonte
