Workflow: ezcWorkflowNodeVariableSub

[ Tutorial ] [ Theoretical background ] [ Class tree ] [ Element index ] [ ChangeLog ] [ Credits ]

Class: ezcWorkflowNodeVariableSub

Subtracts a workflow variable from another variable or a constant value. [source]

An object of the ezcWorkflowNodeVariableSub class subtracts a given operand, either a constant or the value of another workflow variable, from a specifled workflow variable.

This example will subtract five from the contents of the workflow variable 'wfVar' and put the result back in 'wfVar'.

1.  <?php
2.  $sub = new ezcWorkflowNodeVariableSub(
3.    array( 'name' => 'wfVar', 'operand' => 5 )
4.  );
5.  ?>

If operand is a string, the value of the workflow variable identified by that string is used.
