PHP analog ASP. Webfrom Button Submit Event Instance _php instance

Because the company needs PHP project development, PHP just get started, in the Write button submission process, the button event in ASP. First look at the following code,

<?require_once '. /inc/eventhelper.php '; function Page_Load () {echo ' will run at any time
'; if (! Page::ispostback ()) {echo ' Load product category
' If ($_get[' cmd ']== ' edit ') {echo ' modifies the loading of product information that needs to be modified
';}}} function Badd_click () {//COMM::CHECKQX (' Product management _ add '); echo "Badd_click
";} function Bedit_click () {//COMM::CHECKQX (' Product Management _ Modify '); Echo ' proid= '. $_get[' proid ']. '
'; Echo ' Bedit_click
";} function Sdfsdfdsf_click () {echo ' e44444444444444444444
";}? >

The above code should be a bit familiar to the ASP, such as: Page_load,page.ispostback,badd_click, which are like the events of ASP.

The above code runs the Badd_click function when the "Add" button is clicked (for the time being, functions seem to mean the function), and similarly, clicking the "Modify" button automatically runs the Bedit_click event. Do not need too many parameter changes, and do not need too many files, if the page function is not very complex situation, with this mode can be developed quickly.

Here's a look at the code for this eventhelper.php file:

<?class page{//Whether postback data, 1: Is public static function IsPostBack () {global $SYSRunEventName; return!empty ($ Sysruneventname);} Load and Execute event function eventload () {global $SYSRunEventName; $arrEvent =get_defined_functions (); $arrEventUser = $arrEvent [ ' User '; $arr =array_keys ($_post); foreach ($arr as $row) {$name =strtolower ($row); foreach ($arrEventUser as $row 1) {$ Name1=str_ireplace (' _click ', ' ', $row 1); if ($name = = $name 1) {$SYSRunEventName = $row 1;break;}} if (!empty ($SYSRunEventName)) {break;}} if (function_exists (' Page_Load ')) Page_Load (); $SYSRunEventRunName =strtolower ($SYSRunEventName); if (page::i Spostback ()) {$SYSRunEventName ();}}} Class Comm{public static function GetParam ($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 ();? >

All of the above features can be tested under my php5.4 can be run successfully, but in terms of security has not been considered too much, read some articles PHP will be possible to execute PHP code through the client, because PHP is a lot of practical features.

About Comm::getparam, because you often need to get parameters for Get mode, or modify parameters, such as paging needs to keep all the URL parameters, only to modify the paging parameters (such as page=5), so you write some code yourself.

The main use of PHP following several features:

Function_exists
Get_defined_functions

and using the principle of common form submission, using the submit principle to implement the function.

Because of the time rush, too late to explain the specific principles, but also forgive me, code can be understood by everyone.
