I am getting the error. I am not sure why. Because my categories model and post model is working just fine with similar functions. I know this is not a db error as I have already tested.

Error:

A PHP Error was encountered
Severity: Notice

Message: Undefined index: name

Filename: views/admin_comments_edit.php

Line Number: 9

This error is happening for every name of field in my form.

Have you auto-loaded the form helper because it is not included in the controller and no field name in your form is called "name".

Quote:Have you auto-loaded the form helper because it is not included in the controller and no field name in your form is called “name”.

Yes, the form helper is auto-loaded in my config/autoload.php

I changed my from field names to:

Code:
<br />
<h1>&lt;?php echo $title;?&gt;</h1>

&lt;?php

$data = array();
echo form_open('admin/comments/edit');
echo "<p><label for='name'>Name</label><br/>";
$data = array('name'=>'name','id'=>'name','size'=>25, 'value' => $comment['name']);
echo form_input($data) ."</p>";

echo "<p><label for='email'>email</label><br/>";
$data = array('name'=>'email','id'=>'email','size'=>40, 'value' => $comment['email']);
echo form_input($data) ."</p>";

echo "<p><label for='body'>body</label><br/>";
$data = array('name'=>'body','id'=>'body','rows'=>5, 'cols'=>'40', 'value' => $comment['body']);
echo form_textarea($data) ."</p>";

echo "<p><label for='status'>Status</label><br/>";
$options = array('active' => 'active', 'inactive' => 'inactive');
echo form_dropdown('status', $options, $comment['status']) ."</p>";

echo form_hidden('id', $comment['id']);
echo form_submit('submit', 'update comment');
echo form_close();
?&gt;
<br />

I still have the same errors.

[eluser]ppwalks[/eluser]
is this for your "edit form", you have $comment['name'] and in your controller its called "comments", this will throw an error and also if it is an edit form how is the array being sent to the form is it an sdobject array if so you would write $comments->name;

#6
[eluser]ppwalks[/eluser]
print your array using print_r function

#7
[eluser]swgj19[/eluser]
Yes, it is admin_comments_edit.php form.
I changed to $comments->name and I get error saying trying to get property of non-object.
So I changed back the way I had it.
I also did echo $comments in the form and it just says "Array".

#8
[eluser]ppwalks[/eluser]
use print_r thats what it is for, show the array through print_r not echo

#9
[eluser]swgj19[/eluser]
I just used print_r ($comment);
The result is Array()

I also used var_dump ($comment);
The result is array(0) { }

#10
[eluser]ppwalks[/eluser]
Remove function edit($id=0){ and change it to edit($id){
