    <p>i am working on a blog in angularJS and i use php to generate a json with data from a database. My angular 'get article' function looks like this</p> <pre><code>$scope.getDetail = function() { $http.get('php/blogGetArticle.php?id=2').success(function(json) { $scope.jsonDetail = json; alert('ok'); }).error(function() { alert('error'); }); }; </code></pre> <p>and my php 'blogGetArticle.php' looks like this.</p> <pre><code>&lt;?php $id = $_GET['id']; $dbhost = "localhost"; $dbport = "5432"; $dbname = "pd"; $dbuser = "postgres"; $dbpass = "123"; $connect = pg_connect("host=" . $dbhost . " port=" . $dbport . " dbname=" . $dbname . " user=" . $dbuser . " password=" . $dbpass); if(!$connect) die("error 0"); // connect error $query = "SELECT * FROM blog WHERE id=" . $id; $result = pg_query($connect, $query); if(!$result) die('error 1'); // query error $row = pg_fetch_row($result); $json = '{'; $json .= '"id":"' . addslashes($row[0]) . '",'; $json .= '"title":"' . addslashes($row[1]) . '",'; $json .= '"message":"' . addslashes($row[2]) . '",'; $json .= '"category":"' . addslashes($row[4]) . '"'; $json .= '}'; echo $json; ?&gt; </code></pre> <p>Now what i try to do is i try to make the angular function take to the .error branch when i call something inside php .. i dont know how to explain well. Example when i have in php an id that is lower than 10, i want the angular function to throw an exception but i want to make it from php file to throw that exception to angular function.</p> <p>Thank you, Daniel!</p> <p>EDIT: so how do i throw a 4xx or 5xx error ?</p>

    1. COI don't know about PHP, but if you return HTTP response codes 4xx or 5xx depending on the situation, those confirm to HTTP errors.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
