Workflow: ezcWorkflowNodeVariableMul

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

Class: ezcWorkflowNodeVariableMul

Multiplies a workflow variable with another variable or a constant value. [source]
An object of the ezcWorkflowNodeVariableMul class multiplies a specified workflow variable with a given operand, either a constant or the value of another workflow variable.
This example will multiply the contents of the workflow variable 'wfVar' by five and put the result in 'wfVar'.
1.  <?php
2.  $mul = new ezcWorkflowNodeVariableMul(
3.    array( 'name' => 'wfVar', 'operand' => 5 )
4.  );
5.  ?>
If the operand is a string, the value of the workflow variable identified by that string is used.
