enter code herethis is php code

$choice_spc_port = $_POST["txtSpace"];  (THIS LINE GIVES UNDEFINED INDEX NOTICE)
$choice_loc = $_POST["txtLocation"]; (THIS LINE GIVES UNDEFINED INDEX NOTICE)

And this is HTML Form

<form id="animalform" name="animalform" method="post" action="animalform.php">
<div  class="wrapper"> <strong><span>*</span> Text Space portion:</strong>
            <div class="formText">
              <input type="radio" name="txtSpace" value="HR"/>Text space for Horse.<br />
      <input type="radio" name="txtSpace" value="ZB"/>Text Space For Zebra<br />
</div>
</div>

<div class="wrapper"> <strong><span>*</span> Animal Location:</strong>
                <div class="formText">
                <input type="radio" name="txtLocation" value="txtSetXY"/> Specify Animal Location<br />
                    <div style="padding-left:20px;">
                    X: <input type="text" id="locField" name="txtXLocation">  <span>Taking (x=1,y=1) top left box. Increment +1 in value of X moving right</span><br />
                    Y: <input type="text" id="locField" name="txtYLocation">  <span>Taking (x=1,y=1) top left box. Increment +1 in value of Y moving downwards</span><br />
                    </div>
                    <input type="radio" name="txtLocation" value="Default"/>Default
                </div>

            </div>
</div>

Query to insert in database

$insert = "INSERT INTO dbForm (db_space_portion, db_animal_location) VALUES ('{$choice_spc_port}', '{$choice_loc}')";

I tried the same in firefox and those two lines give notice as mentioned in bracket. Also on internet many people are looking for solution. So I think this question will help many out there.

isset method solved the problem.. Thankx guys a lot for answering :) — Ashis, Jan 30 '13 at 10:23

This error shows in newer version of PHP.

There are various way to remove the error:

You can use error suppress method for this
Check that variable is not empty or set it to 0 e.g. choice_spc_port=0 at the start
Isset method also works good

use isset for this, it will not give you undefined index notice when the $_POST['txtSpace'] and $_POST['txtLocation'] are empty and not set.

if(isset($_POST['txtSpace']))
{
     $choice_spc_port = $_POST["txtSpace"];  
}
if(isset($_POST['txtLocation']))
{  
     $choice_loc = $_POST["txtLocation"];
}

what is the meaning of this line? if(isset($_POST['txtSpace'])) – Ashis Jan 30 '13 at 10:24
@Ashis this line checks that `$_POST['txtSpace']` contains any value or not. – Yogesh Suthar Jan 30 '13 at 10:42

Do this to get any Post variables:

if(isset($_POST['txtSpace'])){$choice_spc_port = $_POST["txtSpace"];}
if(isset($_POST['txtLocation'])){$choice_loc = $_POST["txtLocation"];}

And to your SQL sentence:

$insert = "INSERT INTO dbForm (db_space_portion, db_animal_location) VALUES ({'$choice_spc_port'}, {'$choice_loc'})";

Use this query.

if(isset($_POST['txtSpace'])) {
    $choice_spc_port = $_POST['txtSpace'];
}
if(isset($_POST['txtLocation'])) {
    $choice_loc = $_POST['txtLocation'];
}

$insert = mysql_query("INSERT INTO dbForm (db_space_portion, db_animal_location) VALUES ('{$choice_spc_port}', '{$choice_loc}')");
