Retain the page update by Javascript and run the PHP code?

Question

In a php project I need to add items to database, list them & allow the user to edit & update items using a single page.

This is my code to edit item link in HTML table

echo  '<a href="  '.$_SERVER['PHP_SELF'].'?name=edit&id='  .$rowCountry->CountryId .' " id="edit"  onClick="MyFunction()"> Edit </a>';

When a user click on the above link I need to hide Add button and display two new buttons to Update & Cancel the edit + display selected item name in a Text box to Edit.

To hide and display buttons I'm using jQuery and to display the item name i need to use PHP. Here when i put PHP code and reload the page with $_SERVER['PHP_SELF'] (as in above code), hiding & displying of buttons is lost after the page load. (If I remove the _SERVER['PHP_SELF'] code from link it hides and display buttons as expected (but no php code run))

How can I retain the page update by Javascript and run the PHP code?

I'm new to PHP am I missing something in my code?

$_SERVER['PHP_SELF'] is only a refrence to the php document itself, it doesnt contain any key/value pairs. try using:

echo  '<a href="  '.$_SERVER['PHP_SELF'].'?'. $_SERVER['QUERY_STRING'].
    '&name=edit&id='  .$rowCountry->CountryId .
        ' " id="edit" onClick="MyFunction()"> Edit </a>';

edit: i may have misunderstood the question. you may need something like this:

<?php
if(!empty($_GET[edit])){
    //echo code that u want to show AFTER they click the edit link
}else{
    //echo the code to show if they have NOT clicked the edit link
}
?>

Thanks for your answer, Actually the PHP code runs fine, but the hiding of button is lost when page loads. (as I think its because, it runs the javascript client side-> hides buttons-> run php code in server-> loads the page from server-> button is back as it was).

you should only echo the buttons you need in php. you dont need to show/hide them with jquery... unless your using ajax?
