Since the company needs project development in PHP, and I have just started using PHP, in the process of writing button submissions, the button events in asp.net are better. First look at the code below,

Copy code The code is as follows:

require_once '../inc/EventHelper.php';

function Page_Load()
{
echo 'Will run at any time
';

if(!Page::IsPostBack())
{
echo 'Load product category
';
;
}
}
}

function bAdd_Click(){

//Comm::CheckQX('Product Management_Add');
echo "bAdd_Click
";
}

function bEdit_Click()

{

//Comm::CheckQX('Product Management_Modification');
echo 'proID='.$_GET['proID'].' echo "bEdit_Click
";
}

function sdfsdfdsf_Click()

{

echo "e44444444444444444444
";
}

?>

Those who have done asp.net development should be familiar with the above code, such as: Page_Load, Page.IsPostback, bAdd_Click, these are very similar to asp.net events.

The above code runs the bAdd_Click function when the [Add] button is clicked (let’s call it that, function seems to mean function). Similarly, the bEdit_Click event is automatically run when the [Modify] button is clicked. There is no need for too many parameter changes or too many files. If the page function is not very complex, this mode can be used for rapid development.

Let’s take a look at the code of the EventHelper.php file:

Copy code The code is as follows:

 class Page
 {
 //Whether to post data back, 1: Yes
 public static function IsPostBack()
 global $SYSRunEvent Name ;
             return !empty($SYSRunEventName);                                                                               $SYSRunEventName;

 $arrEvent=get_defined_functions();
 $arrEventUser=$arrEvent['user'];

 $arr=array_keys($_POST);
 foreach($arr as $row)<​​​                $name1=str_ireplace('_click','',$row1);
                                                                            ​break;
 break; }
 }

 if(!empty($SYSRunEventName ))
                                                                                                      exists('Page_Load')) 
               Page_Load();

                                            strtolower($SYSRunEventName);

 if(Page::IsPostBack())
                                               > }
 }

    class Comm
    {
        public static function GetParam($params=array(),$cmd='addoverride')
        {
            $allParam=array();

            if($cmd=='addoverride')
            {
                $arrKeys=array_keys($params);
                foreach($arrKeys as $row)
                {
                    if(!in_array($row,array_keys($allParam))) 
                        $allParam[$row]=$params[$row];
                }
            }
            else if($cmd=='del')
            {
                foreach($params as $row)
                {
                    unset($_GET[$row]); 
                }
            }

            
            $arrKeys=array_keys($_GET);
            foreach($arrKeys as $row)
            {
                if(!in_array($row,array_keys($allParam)))
                    $allParam[$row]=$_GET[$row];
            }

            $p='';
            $arrKeys=array_keys($allParam);
            foreach($arrKeys as $row)
            {
                $p.=$row.'='.$allParam[$row].'&';
            }
            return rtrim($p,'&');
        }
    }

    Page::EventLoad();
?>
