How to skip Previous Step page on Processmaker?

[mishika]

Hello,

May you please elaborate your requirement?
Do you want to hide the Previous step button or do you want to skip the complete page of Assign Task where you have the previous step button?

Best Regards
Mishika

Hello rayigo,

If you want the hide the screen shown in the Screenshots, you need to create a trigger with the following code:

Code: Select all

PMFDerivateCase(@@APPLICATION, @%INDEX);
G::header("Location: casesListExtJsRedirector");
die();

The task, where you want to hide this trigger, set this trigger to fire Before Assignment.

Hope this helps.

Best Regards,

You can permanently remove the "Previous Step" link, by editing the file workflow/engine/templates/cases/cases_ScreenDerivation.html and changing the code from:

Code: Select all

                  {if $PREVIOUS_PAGE}
                  <td valign='top' class='tableOption' width='33%' align="left">
                  <table cellspacing="0" cellpadding="0" width='100%'>
                    <tr>
                      <td class='tableOption' align="left" width="120"><img src="/images/bulletButtonLeft.gif" width="6" />&nbsp; <a class="tableOption" href='{$PREVIOUS_PAGE}' id="form[DYN_BACKWARD]" name="form[DYN_BACKWARD]" onclick="">{$PREVIOUS_PAGE_LABEL}</a></td>
                      <td class='tableOption'>&nbsp;</td>
                    </tr>
                  </table>
                  </td>
                  {/if}

To:

Code: Select all

                  <!--
                  {if $PREVIOUS_PAGE}
                  <td valign='top' class='tableOption' width='33%' align="left">
                  <table cellspacing="0" cellpadding="0" width='100%'>
                    <tr>
                      <td class='tableOption' align="left" width="120"><img src="/images/bulletButtonLeft.gif" width="6" />&nbsp; <a class="tableOption" href='{$PREVIOUS_PAGE}' id="form[DYN_BACKWARD]" name="form[DYN_BACKWARD]" onclick="">{$PREVIOUS_PAGE_LABEL}</a></td>
                      <td class='tableOption'>&nbsp;</td>
                    </tr>
                  </table>
                  </td>
                  {/if}
                  -->

The problem is that this eliminates the Previous Step link for ALL processes. If you only want to eliminate the link for certain processes, then you need to add code like this to workflow/engine/methods/cases/cases_Step.php. In line 777, change this code:

Code: Select all

        case 'ASSIGN_TASK':
            $oDerivation = new Derivation();
            $oProcess = new Process();
            $aData = $oCase->loadCase( $_SESSION['APPLICATION'] );

            $aFields['PROCESS'] = $oProcess->load( $_SESSION['PROCESS'] );
            $aFields['PREVIOUS_PAGE'] = $aPreviousStep['PAGE'];

Add a array of IDs for processes which should not have the "Previous Step" link displayed:

Code: Select all

        case 'ASSIGN_TASK':
            //set to the IDs of processes which should not display the Previous Step link:
            $aProcessesNoPreviousLink = array(
               '12067430558ded97f8666c8026604805', 
               '20419177758dec3f7bedd17038026045', 
               '34414124958d30cc2853ae9014839646'
            );
            $oDerivation = new Derivation();
            $oProcess = new Process();
            $aData = $oCase->loadCase( $_SESSION['APPLICATION'] );

            $aFields['PROCESS'] = $oProcess->load( $_SESSION['PROCESS'] );
            if (in_array($_SESSION['PROCESS'], $aProcessesNoPreviousLink))
               $aFields['PREVIOUS_PAGE'] = null;
            else
               $aFields['PREVIOUS_PAGE'] = $aPreviousStep['PAGE'];
