Question

Im using the following code for records inserting into database field.I want to correct the following if and else condition because when records are inserting in database it should echo 0 but it is giving 1.Im unable to figure out the problem.Please i need correction in my code.

<?php    /****************dbfile.php****/
$data = $_REQUEST['columns_one'];
$store_data = explode(",",$data);
//print_r($store_data);
$con = mysql_connect("localhost","root","");
mysql_select_db("formbuilder",$con);

$query = "INSERT INTO record(form_id,form_structure) VALUES('1','value')";
$result = mysql_query($query);

if(mysql_num_rows($result)>0)
{
    echo 0;
}
else
{
    echo 1;

}

?>

<script>   <!--- ajax call----->
$.post("dbfile.php", {columns_one:columns_one },  
            function(result){  
                //if the result is 1  
                if(result == 1){
                alert('success');  

                    return true;
                }else{ 
                alert('fail'); 

                    return false;

                }  
</script>

You are using the wrong function. mysql_num_rows will not return the rows affected by INSERT statements, see here:

http://www.php.net/manual/en/function.mysql-affected-rows.php

Use mysql_affected_rows.
