foucquet Posted April 23, 2012 Share Posted April 23, 2012 I am trying to pull images from my Flickr account with some success except that of accessing the description to be used as a caption for the image. What I have so far is:- <?php //>>> Define some variables $maximgs = 5; $images = array(); $params = array( 'api_key' => '***********************', 'method' => 'flickr.photos.search', 'user_id' => '****************', 'sort' => 'date-posted-desc', 'format' => 'php_serial', 'extras' => 'description', ); $encoded_params = array(); foreach ($params as $key => $value){ $encoded_params[] = urlencode($key) . '=' . urlencode($value); } //>>> Make request and decode the response $url = 'http://api.flickr.com/services/rest/?' . implode('&', $encoded_params); $response = file_get_contents($url); $response_object = unserialize($response); //var_dump($response_object['photos']['photo']); //>>> Why is this returning 100 results? if($response_object['stat'] !== 'ok'){ echo "Something went wrong!"; } //>>> Select the required number of images ($maximgs) for($loop = 0; $loop <= $maximgs; $loop++){ $images = $response_object['photos']['photo'][$loop]; var_dump($images); //>>> Url of the individual image location for the img src. $imgurl = 'http://farm'.$images['farm'].'.'.'static'.'.'.'flickr.com/'. $images['server'].'/'.$images['id'].'_'.$images['secret'].'_n.jpg'; //>>> Url of the individual image for the link. $flkrurl = 'http://www.flickr.com/photos/'.$images['owner'].'/'.$images['id'].'/'; /*The complete Url (<a href="link($flkrurl)"> <img alt="$images['title']" src="image location"($imgurl) width="required width of image" /> </a>) */ $compurl = '<a href="'.$flkrurl.'" target="_blank">'.'<img alt="'. $images['title'].'" src="'.$imgurl.'" width="320px" /></a>'; //>>> Display Images echo $compurl . '<br />' . $images['description']['content']; //<<<<<< Line 66 } ?> Which annoyingly throws this error:- Notice: Undefined index: content in C:\wamp\www\php\flickr_test1.php on line 66 The result of a var_dump():- array 'id' => string '6914498038' (length=10) 'owner' => string '************' (length=12) 'secret' => string '601a885f31' (length=10) 'server' => string '7137' (length=4) 'farm' => float 8 'title' => string 'newhaven_15' (length=11) 'ispublic' => int 1 'isfriend' => int 0 'isfamily' => int 0 'description' => array '_content' => string 'Great reflections found in Newhaven Harbour.' (length=44) with the info that I want to extract underlined. What I can't figure out is how to find out the name of the array below "description =>". I have been scratching my head for several hours now and am no nearer to working it out. Maybe a genius here will have the solution.

MMDE Posted April 23, 2012 Share Posted April 23, 2012 If the vardump has not been modified, I would guess this works: $images['description']['_content'] ^ See the extra underscore before content. array '_content' => string 'Great reflections found in Newhaven Harbour.'

foucquet Posted April 23, 2012 Author Share Posted April 23, 2012 ^ See the extra underscore before content. What a dummy! Didn't spot the underscore, so bleedin' obvious when pointed out. That works perfectly MMDE thanks. Link to comment https://forums.phpfreaks.com/topic/261476-array-access-problem/#findComment-1339837 Share on other sites More sharing options...
