Re: about "Notice (8): Undefined index:"

Hi Jerome


Place who have pointed out, it was my mistake of copy and paste.

By the way, earlier, was found to cause.


Was v5.0.33 version of PDO Driver for MySQL on the server I'm using.
For this purpose,
lib \ Cake \ Model \ Datasource \ Database \ Mysql.php
was due getColumnMeta function that will be used in the resultSet function can not get the table name.

Thank you to answer me.

hi there,

i think your "index.ctp" file not correct.

you write

<table>
<php foreach ($ userData as $ data):??>
<tr>
   <td> <? php echo $ data ['User'] ['name'];?> </ td>
</ tr>
<php endforeach;??>
</ table>

please write <?php ..... ?> and not <php .... ??>

try this one

<table>
<?php foreach ($userData as $data): ?>
<tr>
   <td><?php echo $data['User']['name'];?> </ td>
</ tr>
<?php endforeach; ?>
</ table>

i hope it helps you

I'm using 2.3.1 cakephp.
When you run the following simple code, "Notice (8): Undefined index: User [APP / View / Users / index.ctp, line 6]" occurs.
If you run in cakephp 2.3.1 on another server the same code, the error does not occur.

--------- UsersController.php -----------
class UsersController extends AppController {
    public $ uses = array ('User');
    public $ layout = 'default';
    public function index () {
      $ userData = $ this-> User-> find ('all');
      $ this-> set ('userData', $ userData);
    }
}

--------- User.php -----------
class User extends AppModel {
    public $ name = 'User';
}

--------- Index.ctp -----------
<table>
<php foreach ($ userData as $ data):??>
<tr>
   <td> <? php echo $ data ['User'] ['name'];?> </ td>
</ tr>
<php endforeach;??>
</ table>

--------- Debug ($ userData) -----------
$ userData = array (
   (int) 0 => array (
     (int) 0 => array (
             'id' => '1 ',
             'name' => 'suzuki'
     )
   )
)

Set so the server, I think that there is such a phenomenon occur?
If there is a point that I noticed something, please advice.
best regards
