Question

I am able to post a string to the PHP file but when I try and select an input field within a form to post the value inside it to the PHP file it doesn’t work. Am I selecting the value in the input field correctly?

.js

$.post("js/data.php", {postid: form.postid.value},
            function(output){
                $("#gotpostid").html(output).show();
            }).fail(function(x,y,z){ 
                $("#gotpostid").html(x + "<br />" + y + "<br />" + z)
            });

index.php

<div class="post">
<form name="form"><input type="text" name="postid" value="1234" />
</div>

If i simply do {postid: "some text"} it works fine.

Answer 1

Try the following:

<input type="text" name="postid" id="postid" value="1234" />

and grab the value by doing

value of postid is $("#postid").val() instead form.postid.value
