Question

I have the following codes, I added the debug and this is the data that I am able to retrieve from the database. I wish to display the ['User']['firstName'] and also the ['Passion']['passion_tag'] in the view page, how do I do it? I am facing error such as:

Notice (8): Undefined index: passion_tag [APP\views\searches\simple_search.ctp, line 127]

Answer 1

It looks like that this is part of a larger result set retrieved with $this->Model->find( 'all' ), so I assume you want to display all names from those results. You have to loop through all results to get individual names. Also, each user has several Passions so again you have to loop through them if you want to display them all.

echo 'Our users and their passions are: <ul>';

foreach( $this->data as $user ) {
    echo '<li>';
    echo $user[ 'User' ][ 'firstName' ];
    echo ' who is passionate about: ';
    foreach( $user[ 'Passion' ] as $passion ) {
        echo $passion[ 'PassionsUser' ][ 'passion_tag' ];
        echo ' ';
    }
    echo '</li>';
}

echo '</ul>';
