Fetching data in an AJAX-page

In my AJAX-page I want to fetch data from a database. In my first page I have del image to delete a record. I passed the file cid as 'rmvfile' to the next page and fetched and displayed them on the 2nd page.

In my first page I pass cf_id:

<img src="image/delete1.png" alt="delete" style="width:10px;height:10px" title="Remove" onclick="myFunction('.$fet['cf_id'].');">

function myFunction(cid) {   
    var rmvfile=cid;
    if (confirm("Are you sure you want to Delete the file?") == true) {
        if(cid!='') {
            $.ajax({
                type: 'post',
                url: 'delete_cli_file.php',
                data: {rmvfile: rmvfile},
             });
        }
    }
}

I my 2nd page I use: 

<?php
include "config.php";
$s = $_POST['rmvfile'];
$sel = "select cf_id from client_file where cf_id='".$_POST['rmvfile']."'";
$sel1 = mysql_query($sel);

$sfet = mysql_fetch_assoc($sel1);
$file_name = $sfet['file_name'];  //not fetched
$echeck = "delete from client_file where cf_id='".$_POST['rmvfile']."'";
$echk = mysql_query($echeck);
$del = "delete from client_file where file_name = '$file_name' ";
$del1 = mysql_query($del);
?>

$echeck = "delete from client_file where cf_id = '".$_POST['rmvfile']."'"; and $sel="select cf_id from client_file where cf_id='".$_POST['rmvfile']."'"; are working.

My problem is that the value is not fetched in $sfet['file_name'].

You are not fetching file_name from mysql query

$sel = "select cf_id from client_file where cf_id='".$_POST['rmvfile']."'";

Change query to fetch file_name

$sel = "select cf_id,file_name from client_file where cf_id='".$_POST['rmvfile']."'";

Please correct the sql query section in your code currently it is

$sel = "select cf_id from client_file where cf_id='".$_POST['rmvfile']."'";

it should be 

$sel = "select * from client_file where cf_id='".$_POST['rmvfile']."'";

As now it is fetching only cf_id, you didn't get the other fields.

You have not closed your image-tag properly and the quotes are not closed as well

<img src="image/delete1.png" alt="delete" style="width:10px;height:10px"
title="Remove" onclick="myFunction('.$fet['cf_id'].');">

And as stated by manikiran, check the if.condition.

Change your sql query to this

 $myvar= $_POST['rmvfile'];
  $sel="select cf_id from client_file where cf_id='$myvar'";
  $sel1=mysql_query($sel);

  $sfet=mysql_fetch_assoc($sel1);
  $file_name=$sfet['file_name'];

In your 2nd page

if($sel1=mysql_query($sel)) //Wrong verification

Use == rather than =

if($sel1==mysql_query($sel))
