How can i modify this script?

[xymalf]

<?php

if (isset($_GET['tag'])) {

  do_search($_GET['tag']);

} else {

?>

    <form action="<?php echo $_SERVER['PHP_SELF']?>" method="get">

    <p>Search for photos with the following tag:

    <input type="text" size="20" name="tag"/> <input type="submit" value="Go!"/></p>

    </form>

<?php

}

?>

<?php

 

# uses libcurl to return the response body of a GET request on $url

function getResource($url){

  $chandle = curl_init();

  curl_setopt($chandle, CURLOPT_URL, $url);

  curl_setopt($chandle, CURLOPT_RETURNTRANSFER, 1);

  $result = curl_exec($chandle);

  curl_close($chandle);

 

  return $result;

}

 

function do_search($tag) {

  $tag = urlencode($tag);

 

#insert your own Flickr API KEY here

 

  $api_key = "1a2755a9a5a19904c7f5e661d85db657";

  $per_page="100";

  $url = "http://api.flickr.com/services/rest/?method=flickr.photos.search&api_key={$api_key}&tags={$tag}&per_page={$per_page}";

 

  $feed = getResource($url);

  $xml = simplexml_load_string($feed);

  print "<p>Total number of photos for {$tag}: {$xml->photos['total']}</p>";

 

# http://www.flickr.com/services/api/misc.urls.html

# http://farm{farm-id}.static.flickr.com/{server-id}/{id}_{secret}.jpg

foreach ($xml->photos->photo as $photo) {

  $title = $photo['title'];

  $farmid = $photo['farm'];

  $serverid = $photo['server'];

  $id = $photo['id'];

  $secret = $photo['secret'];

  $owner = $photo['owner'];

  $thumb_url = "http://farm{$farmid}.static.flickr.com/{$serverid}/{$id}_{$secret}_t.jpg";

  $page_url = "http://www.flickr.com/photos/{$owner}/{$id}";

  $image_html= "<a href='{$page_url}'><img alt='{$title}' src='{$thumb_url}'/></a>";

  print "<p>$image_html</p>";

}

 

} # do_search

?>

 

I want to display 300 photos horizontally so they fill the web page - at the moment the script just displays 20 photos vertically.

To get them to display vertically, you could float the <p> tag with CSS.

print "<p>$image_html</p>";

 

For more information, you could search for "creating an image gallery with css".

 

 

 

As a side note, I would recommend avoiding PHP_SELF in the form action attribute for security reasons. Instead, you could just list the page name...or leave it blank.
