h1. Using the REST API with PHP
Here is an example that uses "PHP ActiveResource":http://wiki.github.com/lux/phpactiveresource/, a lightweight PHP library that can be used to access Rails' REST APIs:
<pre>
<code class="php">
<?php
require_once ('ActiveResource.php');
class Issue extends ActiveResource {
var $site = 'http://username:password@192.168.199.129:3000/';
var $request_format = 'xml'; // REQUIRED!
}
// create a new issue
$issue = new Issue (array ('subject' => 'XML REST API', 'project_id' => '1'));
$issue->save ();
echo $issue->id;
// find issues
$issues = $issue->find ('all');
for ($i=0; $i < count($issues); $i++) {
echo $issues[$i]->subject;
}
// find and update an issue
$issue->find (1);
echo $issue->subject;
$issue->set ('subject', 'This is the new subject')->save ();
// delete an issue
$issue->find (1);
$issue->destroy ();
?>
</code>
</pre>
*Known issues*
If you are working with large descriptions the webserver can return a 417 error (Bad Expectation).
You should replace line 381 in ActiveResource.php with the following code:
<pre>curl_setopt ($ch, CURLOPT_HTTPHEADER, array ('Expect:',"Content-Type: text/xml", "Length: " . strlen ($params)));</pre>
*2011-10-05:*
If you are trying to use the class to write time_entries, you will get a 404 response. The reasone is, that the class is unable to create the correct singular form from the pluralized version of the entitiy name. this can be patched by
# adding the class var <code class="php">protected $sOriginalElementName = '';</code>
# changing the constructor to set the class var using the original entity name before the pluralization is called:
<code class="php">
function __construct ($data = array ()) {
$this->_data = $data;
// add this line here - to store the original name of the entity
$this->sOriginalElementName = ($this->element_name ? $this->element_name : strtolower (get_class ($this)));
// Allow class-defined element name or use class name if not defined
$this->element_name = ($this->element_name ? $this->pleuralize ($this->element_name) : $this->pleuralize (strtolower (get_class ($this))));
...
</code>
# and then Changing the Method _send_and_receive to use sOriginalElementName instead of substr ($this->element_name, 0, -1);
<code class="php">
function _send_and_receive ($url, $method, $data = array ()) {
$params = '';
$el = $this->sOriginalElementName;//substr ($this->element_name, 0, -1);
if ($this->request_format == 'url') {
...
