Hi,
I am a newbie so please sorry if the question seems basic but I cannot
find this solution:
I have created a Posts table with the following attributs:
id,
title,
bodytext,
etc.
I now want to test the findby<fieldame> function so I create a
function called "findbytitle" in my posts_controller.php script. This
function takes in a form input to retrieve the row in the table that
has the same title. I want then to call a "view" with the id matching
the title. I did:
...
function findbytitle($id = null)
if ($this->Post->findByTitle($this->data['Post']['title']))
{
$var = $this->Post->findByTitle($this->data['Post']['title']);
$this->redirect('/posts/view/' . $var);
}
...
but it does not work
$var is an array. in my case it is:
Array ( [0] => Array ( [id] => 3 [title] => Title strikes back [body]
=> This is really exciting! Not. [created] => 2008-06-29 21:35:37
[modified] => 2008-06-30 22:00:25 ) )
I then tried:
...
function findbytitle($id = null)
if ($this->Post->findByTitle($this->data['Post']['title']))
{
$var = $this->Post->findByTitle($this->data['Post']['title']);
$this->redirect('/posts/view/' . $var[0]['id']);
}
...
but I got:
Notice: Undefined index: 0 in C:\Program Files\EasyPHP 2.0b1\www\cake
\app\controllers\posts_controller.php on line 66
I do not know how to retrieve the value of the id from the array.
I am struggling. Can someone tell mw what the right syntax is or what
instructions I should be using!
Many thanks
