Using Delphi for PHP

AJAX Applications

Set the following settings:

Enable form to process AJAX. Eg: Form1.UseAjax = true;

Enable control to call AJAX routine. Eg: For Button1 control create a routine like this:

class Form1 extends Page {
   $Button1 = null;
   . . .  // other controls defined here
 
   function Button1JSClick($sender, $params)
   {
      echo $this->Button1->ajaxCall("WhateverRoutineToCall");
      ?>
        // always finish with this javascript statement
        // when using a Submit button (if you do not want
        // to reload the form.    
        return(false);  
      <?php
   }
 
   function WhateverRoutineToCall()
   {
      // do something here (just do not include echo statements)
   }
 
   . . .  // other functions defined here
}

Note: Do not put echo statements in the function that is called by ajaxCall(). Otherwise the AJAX code will not work.

Localize an Application

Perform the following steps:

Any references to a string in your code (eg: echo “Hello, world!”; ) should be replaced by a call to gettext() or _(). Eg:
```
echo _("Hello, World!"); 
```
Set the Language property for the form to the required locale.
Translate the user interface in the form to the required locale. This creates a form1.<locale>.xml.php file that contains all the specific changes made to that locale.
Run the Internationalization Wizard (Tools > Internationalization Wizard) to create the directory structure and files used by gettext.
Create or edit the localization files for your language using poEdit. poEdit calls it a 'catalog'. The file is found in the project directory under locale/<locale>/LC_MESSAGES/messages.po. After saving the poEdit catalog (eg: messages.po file), poEdit will create a .mo binary file which is what it is used by your application.

Set Language property in the OnCreate event for the form, and translate the required form controls. Eg:

function Form1Create($sender, $params)
{
  // set locale
  $this->Language = "Danish";
 
  // translate form controls
  $this->btnSave->Caption        = _("Save");
  $this->btnDownload->Caption    = _("Download");
  $this->lblLanguage->Caption    = _("Language");
  $this->lblProductName->Caption = _("Product Name");
  $this->lblCompanyName->Caption = _("Company Name");
 
}
