Question

I have what should be a simple form to pass data to a php page. The form is:

Answer 1

use

<input type="text" id="SetListName" name="SetListName" />

you have not used name attribute

Answer 2

You need to have a 'name' attribute in the form for each input field that you want to read in PHP. So you're code should read:

<form action="php/setlist.php" method="post"> 
<input type="text" id="SetListName" name="SetListName"/>
<input type="hidden" id="newList" name="newList" value="" readonly="readonly" style="border: none;">
<input type="submit" style="width:150px;"><br /><br />

Answer 3

Replace

<input type="text" id="SetListName" />

with

<input type="text" id="SetListName" name ="SetListName"/>

Answer 4

You are missing name attribute in:

<input type="text" id="SetListName" />
