Preface

There are many formats the reports can be sent to, Infact I use the FPDF library to turn mine into PDFs and a recent thread about report writing mentioned using the ATKOpenDocumentWriter class in ATK to create ODF files.

I'm going to focus firstly on the basics to get a report to appear on the screen, and then possibly expand this to include how I used the FPDF library to save PDF files since first you want to know how to do it in ATK.

Start with any empty node

First you start off with a normal node, but leave it empty:

Empty myReport Node

class myReport extends atkNode
{
	function myReport ()
	{
		$this->atkNode("myReport");
	}
}

action_report Action

This appears to be where the action happens. It start's the page and calls the [getMyReport] function which both presents the form to filter/sort your data on, and display the resulting report.

action_report code

Add the following to your report class below the constructor:

	function action_report()
	{
		// Here is the meat of the report and where everything happens
		$content = $this->getMyReport();
		
		// Add the given content to the page
		$page = &$this->getPage();
		$page->addContent($this->renderActionPage("report", $content));
	}

Here we use a function to manage everything called getMyReport();

Main Report code

As stated above this is where the the report is generated and presented, also the sorting/filtering choices are presented/configured here as well.

getMyReport function

  function getMyReport()
  {
    // Get a reference to the sessionmanager
    global $sessionManager = &atkGetSessionManager();
 
    $this->addStyle("style.css");
 
    // Try to get a reference to the User Interface object and raise an error if it fails
    $ui = &$this->getUi();
 
    // Add a newline (vertical spacing)
    $output.= '<br/>';
    $go = $sessionManager->pageVar("go");
		
    //use this to show the filter screen first, and the report second. 
    // $go gets set as a hidden field in the getFilterBar function.
    if ($go != 1)
    {
      // Start composing the output by adding the filterbar as topmost item
      $output = $this->getFilterBar();
      $output.= '<br/>';		
    } 
    else 
    {
      // Reporting code goes here, use techniques learned in the db 
      // access section to get your data out and then just format 
      // standard html to output with
		
      // Render a box around the generated output
      $boxedoutput = $ui->renderBox(array("title"=>$this->actionTitle('ProductionTallySheet'), "content"=>$output));
 
      // Return the generated boxed output
      return $boxedoutput;
    }
  }

getFilterBar function

In this function you can build the filter form.

  function getfilterbar()
  {
    // get data to filter based on constraints for the report.
    $record = $this->getFilterRecord();
	  
    //get the filter attributes
    $attrs = &$this->getFilterAttrs();
	  
    $output = '<form action="dispatch.php" method="get">';
    $output.= atkSessionManager::formState();
    $output.= '<input type="hidden" name="go" value="1">'; //trigger to prevent loading the first time
    $output.= atktext("Date","production").' '.$attrs["date"]->edit($record); 
    $output.= '<br>';
    $output.= atktext("name").": ".$attrs["name"]->edit($record)." ";
    $output.= '<br>';
    $output.= atktext("shift").": ".$attrs["shift"]->edit($record)." ";
 
    $output.= ' <input type="submit" value="'.atktext("refresh").'">';
    $output.= '</form>';
    return $output;
  }

getFilterRecord

Grab the data to be filtered/sorted on

  function getFilterRecord()
  {
    static $s_record = NULL;
 
    $sessionManager = atkGetSessionManager();
		
    if ($s_record==NULL)
    {
      $s_record = array();
      $s_record["name"] = $sessionManager->pageVar("name");
      $s_record["shift"] = $sessionManager->pageVar("shift");
      $s_record["date"] = $g_sessionManager->pageVar("date");
			
      $attrs = &$this->getFilterAttrs();
      foreach (array_keys($attrs) as $attribname)
      {
	$p_attrib = &$attrs[$attribname];
	$s_record[$attribname] = &$p_attrib->fetchValue($s_record);
      }
			
      $go = $sessionManager->pageVar("go");
      if ($go != 1)
      {
        // initial loading. 
	//set name to current logged in person
	$user = getUser();
	$s_record["name"] = array("id"=>$user["id"]);
				
        // We'll put the to to todays date
	$s_record["date"] = date("Ymd");
      }
    }
    return $s_record;
  }

getFilterAttrs

Get the attribute info for the fields you're going to use to sort/filter on so they render normaly on the screen.

  function &getFilterAttrs()
  {
    userelation("atkmanytoonerelation");
    useattrib("atkradioattribute");
    $attrs["name"] = &new atkManyToOneRelation("name", "access.users");
    //$attrs["name"]->setNoneLabel("Do not filter");
    $attrs["shift"] = &new atkRadioAttribute("shift", array("1 ST","2 ND","3 RD"), array("1 ST","2 ND","3 RD"));
    $attrs["date"] = &new atkDateAttribute("date");
 
    return $attrs;
  }

Conclusion

There are many things that can be expanded upon here but this is the basic skeleton method borrowed from Achievo examples.

You may also want to have a look at atkBaseReport. It's a predefined class containing some of the constructs mentioned above.
