Submitting multiple form fields using a PHP function without $

Suppose if you have form with 25 fields and have to save into a database table, then we have to get values of each field, escaping its value to protect SQL Injection , so you have some lengthy code .

For example when submitting a Form :

<?php isset($_POST[‘submit’){

$name =$_POST[‘name’];$mobile =$_POST[‘mobile’];//and so on

}?>

In this Tutorial I am going to tell how it can so easy and short creating a php function.

First create table company using phpmyadmin its so simple, then create a table staffs under database company.

Staff table Fields you can get from form’s name, remember name of field of database and form name should be equal otherwise function save will not work.

         save($db,$fields);
}
function save($db,$fields,$table){
           $fname="";
           $fvalue="";
           foreach($fields as $name=>$value){
                $value=$db->real_escape_string($value);
                $fvalue.= "'".$value."',";
                $fname.= $name.",";
               //echo $name." => ".$value."<br/>";
           }
           $fname=substr_replace($fname, '', -1);
           $fvalue=substr_replace($fvalue, '', -1);
           $sql="insert into $table($fname) values($fvalue)";
           //echo $sql;

           if($db->query($sql)){
             echo '<div class="alert alert-success">Successfully Saved</div>';  
           }else{
             echo '<div class="alert alert-danger">'.$db->error.'</div>';
           }
