PHP echo selected value from html dropdown list

Question

In my dropdown list, i put all the "pack_name(s)" the user has posted and I display it all in the list for the user to select and update. So when the user selects one and hits submit, i want to get that "value" submitted and use it for later purposes but ive been researching and only found "pre-set" values with html and the value was given using Jquery. So i wondering if its possible to basically take the "pack_name" selected and when the user hits submit, echo out the selected value.

PHP

<?php
session_start();

 if(empty($_FILES) && empty($_POST) && isset($_SERVER['REQUEST_METHOD']) && strtolower($_SERVER['REQUEST_METHOD']) == 'post'){ //catch file overload error...
        $postMax = ini_get('post_max_size'); //grab the size limits...
        echo "<p style=\"color: #F00;\">\nPlease note files larger than {$postMax} will result in this error!</p>"; // echo out error and solutions...
        return $postMax;
    }

if(isset($_COOKIE['id'])){

    if($_SESSION['came_from_upload'] != true){

        setcookie("id", "", time() - 60*60);
        $_COOKIE['id'] = "";
        header("Location: developerLogin.php");
        exit;


    }

    try{

        // new php data object 
        $handler = new PDO('mysql:host=127.0.0.1;dbname=magicserver', 'root', '');
        //ATTR_ERRMODE set to exception
        $handler->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

        }catch(PDOException $e){
             die("There was an error connecting to the database");   

        }
       $userid = $_SESSION['id'];
       $stmt = $handler->prepare("SELECT * FROM pack_profile WHERE pack_developer_id = :userid");
       $stmt->bindParam(':userid', $userid, PDO::PARAM_INT);
       $stmt->execute();
       echo "<select>";

       while($result = $stmt->fetch()){
         echo "<option>" . $result['pack_name'] ."</option>";
       }

       echo "</select>";

   if($_SERVER['REQUEST_METHOD'] =="POST"){
         $token = $_SESSION['token'];


}
}


?>

So what's part of the code isn't working? Please be more specific. Are you getting any errors? — Difster

You need to give the select element a name attribute, and give each option element a value attribute.

For example:

   echo "<select name=\"pack\">";

   while($result = $stmt->fetch()){
     echo "<option value=\"" . $result['pack_name'] . "\">" . $result['pack_name'] ."</option>";
   }

   echo "</select>";

Of course you should be escaping anything which could contain &, < or " with something like htmlspecialchars().

Oh so now do i just echo the "result"

thomasrutter Over a year ago

Result will be in $_POST['pack'] or $_GET['pack']. Your question is confusing since you already have advanced concepts like sessions, file uploads and indeed even $_POST in your code yet you don't seem to know basics how forms work. I'm assuming you are outputting a form element eg <form action="something" method="POST"> somewhere? It's not in your code.

I am so sorry i had a bad headache yesterday but i tried "echo $_POST['pack'}" and i got an error saying "( ! ) Notice: Undefined index: pack in C:\wamp64\www\MT\developer_packupdater.php on line 48 "

I think maybe it would be wise to employ someone who knows web development or PHP to do this work for you - I just feel that it's going to take a bit too much to lead you through this.

Well i am doing this just to learn but thanks for the suggestion.
