simplexml_load_file parse [#attributes] => Array

Closed 9 years ago.
The goal: Using PHP/CodeIgniter, I need to get a list of users and their custom field names and values in a usable array. If I can just get to the items, I can do what I need. Please see OUTPUT with notes for "// <<< " so you can see where I'm stuck. I just can't get past the dang [#attributes].
I'm using PHP to connect to Redmine using ActiveResource.php and their built in REST API. I want to get a list of all the users and am getting the OUTPUT below.
Models/Employees_model.php:
<?php
require_once ('ActiveResource.php');
class Employees_model extends ActiveResource {
var $site = 'http://user:password#localhost:8080/redmine/';
var $element_name = 'user';
var $request_format = 'xml';
function __construct() {
parent::__construct();
}
}
?>
controllers/employees.php:
public function employees () {
$employees = new Employees_model();
$data['employeeList'] = $employees->find('all');
$this->load->view('customers/ajaxEmployees', $data);
}
view/ajaxEmployees.php:
<?php
//I can get the following with no problem
echo $employee->id . "<br/>";
echo $employee->firstname . "<br/>";
echo $employee->lastname . "<br/>";
//This is where I'm stuck (see OUTPUT for [#attributes] and "// <<<" notes)
echo $employee->custom_fields->custom_field;
?>
OUTPUT:
Array
(
[0] => Employees_model Object
(
[id] =>
[site] => http://user:password#localhost:8080/redmine/
[element_name] => user
[request_format] => xml
[extra_params] =>
[user] =>
[password] =>
[element_name_plural] => users
[_data] => Array
(
[id] => 16
[login] => jschmoe
[firstname] => Joe
[lastname] => Schmoe
[mail] => joe#example.com
[created_on] => 2012-08-24T01:58:21Z
[last_login_on] => SimpleXMLElement Object
(
)
[custom_fields] => SimpleXMLElement Object
(
[#attributes] => Array
(
[type] => array
)
[custom_field] => Array
(
[0] => SimpleXMLElement Object
(
[#attributes] => Array
(
[name] => Quality Control //<<< I need this
[id] => 2
)
[value] => 1 //<<< I need this to know that QualityControl = 1
)
[1] => SimpleXMLElement Object
(
[#attributes] => Array
(
[name] => Technical Contractor // <<< I need this
[id] => 3
)
[value] => 0 // <<< I need this to know that TechnicalContractor = 0
)
[2] => SimpleXMLElement Object
(
[#attributes] => Array
(
[name] => Content //<<< I need this
[id] => 4
)
[value] => 0 // <<< I need this to know Content = 1
)
)

Thank you all so much for your help. After wasting many hours searching around, trying everything I came across and everything I could think of - I figured I'd better wave my little white flag. :(

Answer 1

$employee->custom_fields->custom_field; is an array, and you can foreach over it to get each name attribute and its corresponding value using SimpleXMLElement::attributes().
foreach ($employee->custom_fields->custom_field as $cf) {
// Loop over the custom field nodes and read the name of each
switch ($cf->attributes()->name) {
// Load a variable on each matching name attribute
// or do whatever you need with them.
case "Quality Control":
$quality_control = $cf->value;
break;
case "Technical Contractor":
$technical_contractor = $cf->value;
break;
case "Content":
$content = $cf->value;
break;
}
}
Or if you don't know in advance all the ones you'll need, load them into an array:
$employee_attrs = array();
foreach ($employee->custom_fields->custom_field as $cf) {
// Add an array key of the name, whose value is the value
$attrs[$cf->attributes()->name] = $cf->value;
}
var_dump($employee_attrs);

Answer 2

The attributes() function is what you're looking for I think. For example
foreach ($employee->custom_fields->custom_field as $line) {
echo "[" . $line->attributes()->name . "]" . $line->value . "\n";
}
Also you might have to use this instead:
foreach ($employee->_data->custom_fields->custom_field as $line) {
(not sure, try both)
