How to add a special block to a module using templates

The goal of this tutorial is to show how we could add a new block in the edit or detail view of a module where we could add some special functionality that we may need.

To use this strategy you simply have to create a template with the same label as the block followed by _edit or _detail inside the module's template directory.

Inside that file you will be able to use all the variables and functionality of Smarty and a new $FIELDS variable which contains the values of the fields of the record being shown/edited.

No additional functionality is given. You, as a programmer, must create the code to do any magic you need inside this block.

If you need to add a new block this can be done easily both in the layout editor and by using vtlib API.

Next I am going to walk through a simple example by creating a new block called Process Workflow which will show an image to move to next phase of a given business process if it is possible in Detail View and a status message in Edit View.

To create the block we use this vtlib code:

We could use the module manager “Add Block” feature with the same result.

$modname = 'Potentials';
$module = Vtiger_Module::getInstance($modname);
if($module) {
	$block = new Vtiger_Block();
	$block->label = 'ProcessWorkflow';
	$block->sequence = 2;
	$block->sequence = 2;
} else {
	echo "<b>Failed to find $modname module.</b><br>";

Now that we have the block we create the files:


In ProcessWorkflow_detail.tpl I will put this code:

<p align="center"><img src="themes/images/right.gif" width="100px"/></p>
<p align="center">Move to next step in process</p>

And in ProcessWorkflow_edit.tpl I will put this code:

<td colspan="4">
<p align="center">You are now in Step X of the Process and you can proceed to Step Y or Step Z</p>
