      For the curious, after getting the TV’s value with 

      $tv = $doc->getTVValue('docCount');

      or 
      $tv = $doc->getTVValue(4); // 4 is the ID of the TV, not the doc


      You have the value, but you have no reference to the TV itself. Since setValue() is a member of the TV class, you need to get a reference to the TV first with getObject() before calling its setValue() member:

      $tv = $modx->getObject('modTemplateVar', array('name'=>'MyTv'));
$tv->setValue($id,'SomeValue');  // $id is the ID of the doc where you want to change the TV , not the TV

        That’s because it should be this:

        // get the TV docCount in the current doc 
$tv = $modx->getObject('modTemplateVar',array('name'=>'docCount'));

// Add 1 to the value of docCount and call it newValue:
$newValue = $modx->resource->getTVValue('docCount') + 1;

// Set the tv docCount with new value
$tv->setValue($modx->resource->get('id'), $newValue);
$tv->save();



        Hi splittingred,
        thanks a lot. This works very well on my websites. Beside this I was trying to add a couple of different numbers in a TV called "row-of-numbers" step by step by using the php-command "array_push()" but it doesn´t work:

        $tvconv = $modx->getObject('modTemplateVar',array('name'=>'row-of-numbers'));

$newValue = $modx->resource->getTVValue('row-of-numbers');
array_push($newValue,"17");

$tvconv->setValue($modx->resource->get('id'), $newValue);
$tvconv->save();


        The result for the tv "row-of-numbers" should be like this 1 8 12 17

        Do you have any idea what I did wrong?

          Does anybody know what I have to do if I want to change a TV-Value of a resource other than the current document?

          I tried this but it seems like I did a mistake:

          $tvconv = $modx->getObject('modTemplateVar',array('name'=>'mytv'));
$rawValue = $tvconv->getValue($idoftheotherresource);
$newvalue = $rawValue + 3;
$tvconv->setValue('mytv', $newValue);
$tvconv->save();

            Do I maybe have to add the id of the resource anywhere in the save-tag?

              Try this:

              $tvconv->setValue($idoftheotherresource, $newValue);

                I just tried it like this:
                $tvconv = $modx->getObject('modTemplateVar',array('name'=>'mytv'));
$rawValue = $tvconv->getValue($idoftheotheresource);
$newvalue = $rawValue + 3;
$tvconv->setValue($idoftheotheresource, $newValue);
$tvconv->save();

                But it doesn´t work. For testing I changed the line:
                $tvconv->setValue($idoftheotheresource, $newValue);

                into:
                $tvconv->setValue($idoftheotheresource, '19');

                This successfully saves 19 into the TV "mytv" implying that this line is now still the problem:
                $newvalue = $rawValue + 3;


                Do you have any idea how to correct this line?

                Thanks a lot for your help!

                  Try this:
                  $newvalue = (int) $rawValue + (int) 3;

                    Perfect!!! Now it works!!!

                    Do you think it is also possible to create step by step a growing row in a TV like it is possible in php by using the array_push()-command. For example like this:

                    array_push($newValue,"17");


                    On all purpose thanks a lot!!!

                      The solution is much easier than I expected. It works by just using this:
                      $newvalue = $rawValue . 3;

                      Thanks again!!!
