Call php function from same file using javascript

Question

I have a requirement to display contents of a file after clicking it. I am using javascript to call the php function in same file using Ajax. I know we cannot call php function using Ajax but i am trying to call the same file and in php file i am checking the isset() for the parameter which i am sending through ajax. I dont know whats wrong but the code is not working. Can someone please assist me>=?

PHP code am using...

    if(isset($_POST['param3'])){
           echo "I am in displaying data successfull ajax call";
    }

My ajax:

$.ajax({
    type:'POST',
    url : 'surveypanel.php',
    data : {param3:"asdf"},
    success : function(data){
        //
    }
});

Thanks, Kshan

I dont see you trying to make any function call in your php code, also your js code is invalid — Patrick Evans

You never do anything with data in success : function(data){ — Sean

Patrick, As far as i know we cannot call php function from ajax. So am calling the same file and checking isset. Yeah may be i kept a wrong title. But my intenestion is to execute some fraction of php code after the click. So i mentioned it as function. — kshan 2k18

in your php code you can call any function your php code has access to, ie user defined, built-in, functions from included files, etc — Patrick Evans

You would call it in your php file that you are requesting in your ajax request ie, if(isset(..)){ somefunction(); } — Patrick Evans

try this:

$.ajax({
    type:'POST',
    url : 'surveypanel.php',
    data : {param3:"asdf"},
    success : function(data){
        // use data for get response from surveypanel.php
        alert(data);
    }
});

@kshan, you didn't mention about that code fragment ? Share detail , although this is the answer of your question.

Apologies for the confusion. if(isset($_POST['param3'])){ echo "Successfully called same file"; } I have to exectute this after the click. This code is in same php file where i am writing the click. I am checking the parameter "param3" which is calling from ajax call. Let me know if still this is not clear...
