Build filter form by code

This example highlights the code required to make and manage the filter form by code and not by parameters (since CYap 2.1.0).

First, I create the CYAP object as usual.


       <?php
       

       $p=new CYap(array(), array(), $db_info, $Show_info, array());

Then I get the reference to the form object.

    
      // Get the filter object
      

      $FilterObj=$p->GetSearchObject();

First statement, I want the field disposed on two columns. If I don't set anythink the default one column will be used.


      // Form Layout: 2 column layout
      
$FilterObj->SetLayoutClass('CYAP_cls2ColumnLayout');

Now it's time to add our first text box. And configure it


      // Add range of text input object;
      
// Create the field. The index are the same as $SearchFieldCfg
      
$f1=new CYap_clsSearchRangeTxt(array(
      
                             // Textbox label
      
                            'description' => 'Event Date',
      
                            // DataBase field where look for the typed string
      
                            'fieldname'   => 'DEvent',
      
                            // A=alphabetic, N=Numeric
      
                             'type'        => 'A',
      
                            // Field size. Used to set the textbox size
      
                            'size'        => 14,
      
                            /* use regex to match the field
      
                             * contents against the requested
      
                             * string. 1=yes, 0=no */
      
                            'useregex'   => 0 ),'TxtRange');
      
// Add the field to the filter form
      
$FilterObj->AddSearchField($f1,'TxtRange');

The second input text.


      
// Second input. You may setup the parameters later
      
$f2=new CYap_clsSearchRegexOpt(array(),'TxtRegex');
      
// Parameters setup. You may set one paramneter on each call..
      
$f2->LoadCFg(array('description' => 'Event Date'));
      
// ... or many paramters with one call
      
$f2->LoadCFg(array('fieldname'   => 'DEvent',
      
                  // A=alphabetic, N=Numeric
      
                  'type'        => 'A',
      
                  'size'        => 14,
      
                  'useregex'   => 1 ));
      
// Add the field to the filter form
      
$FilterObj->AddSearchField($f2,'TxtRegex');

Third and last input box.


      
//third... select input type
      
$f3=new CYap_clsSearchSelectBox(array( // Label
      
                                      'description' => 'Error Code',
      
                                       // DataBase field where look for the typed string
      
                                      'fieldname'   => 'errno',
      
                                      // A=alphabetic, N=Numeric
      
                                      'type'        => 'N'),'SelectBox');
      
// Now add the available options to choose from
      
$f3->AddOption( 'OK (0)','0');
      
$f3->AddOption( 'Err 512','512');
      
$f3->AddOption( 'Err 1024','1024');
      
// ALL rows option
      
$f3->AddOption( 'No selection','NOFILTER');
      
// Add the field to the filter form
      
$FilterObj->AddSearchField($f3,'SelectBox');

Finally show the result.


     
// Finally show the table
     
$p->showpage();
     
echo '</body></html>';
     
?>
