我目前正在尝试将 flickr api 添加到我的自定义插件中......并且失败了。:( 我试图使用本教程Flickr API 入门来学习基本的代码结构,然后我将参考 flickr 的应用程序花园以获取文档来做我想做的事情;但是,它不起作用。
我有什么...我构建了一个新的 PHP 文件并将其命名为“class.flickr.php”并添加了教程中列出的代码...
<?php
class Flickr{
private $flickr_key;
private $flickr_secret;
private $format = 'json';
// Setting up flickr_key and flickr_secret
public function __construct( $flickr_key, $flickr_secret ) {
$this->myApiKey = $flickr_key;
$thix->myApiSecret = $flickr_secret;
}
public function searchPhotos( $query = '', $tags = '' ){ // Begin searchPhotos
$urlencoded_tags = array();
if ( !empty( $args )) {
$tags_r = explode( ',', $tags );
foreach ( $tags_r as $tag ) {
$urlencoded_tags[] = urlencode( $tag );
}
}
// Construct the url
$url = 'http://api.flickr.com/services/rest/?';
$url .= 'method=flickr.photos.search';
$url .= '&text=' . urlencode( $query );
$url .= '&tags=' . implode( ',', $urlencoded_tags );
$url .= '&sort=relevance';
$url .= '&safe_search=1';
$url .= '&content_type=4';
$url .= '&api_key=' . $this->$flickr_key;
$url .= '&format' . $this->$format;
$url .= '&per_page=10';
// Calling url using curl
$curl = curl_init();
curl_setopt_array( $curl, array(
CURLOPT_RETURNTRANSFER => 0,
CURLOPT_TIMEOUT => 120,
CURLOPT_URL => $url,
));
if ( !curl_exec( $curl )) {
die ( 'Error: "' . curl_error( $curl ) . '" - Code: ' . curl_errno( $curl ));
}
print_r( curl_getinfo( $curl ));
// Get search results
$result = file_get_contents( $url );
// Remove the unneccessary strings that wraps the result returned from the API
$json = substr( $result, strlen( "jsonFlickrApi("), strlen( $result ) - strlen( "jsonFlickrApi(") - 1 );
$photos = array();
$data = json_decode( $json, true );
// Check if the status didn't fail
if ( $data['stat'] != 'fail' ) {
// Return only the data for the photos as that's the only thing that we need
$photos = $data['photos']['photo'];
return $photos;
} else {
return false;
}
} // end searchPhotos
}
然后尝试使用以下代码在我的页面模板(与“class.flickr.php”位于同一文件夹中)中调用上述方法...
<?php // Flickr search photos test
require_once( 'class.flickr.php' );
$flickr = new Flickr( $api_key, $api_secret);
$results = $flickr->searchPhotos( $query, $tags );
if ( !empty( $results )) {
foreach( $results as $photo ) {
$src = "http://farm" . $photo['farm'] . ".static.flickr.com/" . $photo['server'] . '/' . $photo['id'] . '_' . $photo['secret'] . '_m.jpg';
?>
<img src="<?php echo $src; ?>" alt="<?php echo $photo['title']; ?>" />
<?php }
}
但是,唉,我得到的只是一个空白屏幕。任何帮助,将不胜感激。;)
