Class Details

[line 2047]
A component to generate an html hidden field.

This component is useful to send information to another script, set the value for it on the Value property.

The component is only visible at design time.

You can use hidden field for many purposes, in the following example you can use it to store the customer_id selected by the user on the dbgrid and when the user presses the button, then issue an sql sentence to delete it:

  1.  <?php
  2.       class Unit465 extends Page
  3.       {
  4.              public $btnDelete null;
  5.              public $selectedcustomer null;
  6.              public $ddcustomers1 null;
  7.              public $dscustomers1 null;
  8.              public $dbnew_db1 null;
  9.              public $tbcustomers1 null;
  10.              function btnDeleteClick($sender$params)
  11.              {
  12.                       global $input;
  13.                       $selectedcustomer=$input->selectedcustomer;
  14.  
  15.                       if (is_object($selectedcustomer))
  16.                       {
  17.                               echo "Delete customer:".$selectedcustomer->asInteger();
  18.                       }
  19.              }
  20.  
  21.              function ddcustomers1JSRowChanged($sender$params)
  22.              {
  23.              ?>
  24.                       //The value for the hidden field selected customer is set
  25.                       //to the selected customer id, which is the first row of
  26.                       //the dbgrid
  27.                       document.Unit465.selectedcustomer.value=ddcustomers1.getTableModel().getValue(0, ddcustomers1.getFocusedRow());
