Im trying to set a working variable i can use later on in my code, ive got an id in the url that references an attribute in an external data feed. You can see a copy of the xml feed HERE
the id comes in the url like this - /page.php?id=52115351
At the moment im setting my working variable as bellow, buts its just being set to the first instance of 'market' rather than being set against the instance thats got the same id as the one in the url.
$wh_odds = $wh_xml->response->williamhill->class->type->market->participant;
$wh_odds_attrib = $wh_odds->attributes();
$wh_odds_attrib['name'];//name
How would i implement $_GET['id'] with this block so that it would be making the working variable $wh_odds_attrib['name'] from the participant of the correct instance of 'market' in the xml feed ?
If you're using simpleXML you could try something like this:
$simpleXml = simplexml_load_file('test.xml');
$marketNode = $simpleXml->xpath("/oxip/response/williamhill/class/type/market[#id='{$_GET['id']}']");
$attributes = $marketNode[0]->participant->attributes();
echo $attributes['name'];
I am not entirely sure what you are attempting to do but you can just assign the $_GET['id'] to whatever you want, ie $id = $_GET['id'] allowing you to use it in string manipulation (via sprintf or whatever).
A little more information about what you are trying to do, would help

I know that CakePHP params easily extracts values from an URL like this one:
http://www.example.com/tester/retrieve_test/good/1/accepted/active
I need to extract values from an URL like this:
http://www.example.com/tester/retrieve_test?status=200&id=1yOhjvRQBgY
I only need the value from this id:
id=1yOhjvRQBgY
I know that in normal PHP $_GET will retrieve this easally, bhut I cant get it to insert the value into my DB, i used this code:
$html->input('Listing/vt_tour', array('value'=>$_GET["id"], 'type'=>'hidden'))
Any ideas guys?
Use this way
echo $this->params['url']['id'];
it's here on cakephp manual http://book.cakephp.org/1.3/en/The-Manual/Developing-with-CakePHP/Controllers.html#the-parameters-attribute-params
You didn't specify the cake version you are using. please always do so. not mentioning it will get you lots of false answers because lots of things change during versions.
if you are using the latest 2.3.0 for example you can use the newly added query method:
$id = $this->request->query('id'); // clean access using getter method
in your controller.
http://book.cakephp.org/2.0/en/controllers/request-response.html#CakeRequest::query
but the old ways also work:
$id = $this->request->params->url['id']; // property access
$id = $this->request->params[url]['id']; // array access
you cannot use named since
$id = $this->request->params['named']['id'] // WRONG
would require your url to be www.example.com/tester/retrieve_test/good/id:012345.
so the answer of havelock is incorrect
then pass your id on to the form defaults - or in your case directly to the save statement after the form submitted (no need to use a hidden field here).
$this->request->data['Listing']['vt_tour'] = $id;
//save
if you really need/want to pass it on to the form, use the else block of $this->request->is(post):
if ($this->request->is(post)) {
//validate and save here
} else {
$this->request->data['Listing']['vt_tour'] = $id;
}
Alternatively you could also use the so called named parameters
$id = $this->params['named']['id'];
I am editing a template to try and add some conditional logic to my page.
The page template shows topics related to a user.
I want to add a piece of code which will grab the user name from the page we are viewing and then use that in a string for my conditional statements.
The code I have put together is as follows, but it breaks my page so I am doing something wrong.
<?php global
// I query the ID and try and set that to the $userID - I think I am doing this wrong, but when I echo the ID it gets the correct info.
$userID = get_queried_object()->ID;
// This is the string I create using the userID which should be from the query above
$memberstatus = get_user_meta($userID,'member_status',true);
?>
later on I use IF statements to use thsi result (which i know work) so i won't post them. My problem is trying to get the above to work.
Any help?
damm, looks like when I remove 'global' from the php it works! I thought global had to be in this...ah well
I am new to PHP.
I need a help regarding the methods of extracting DB name and table name from the given URL name.
For example, let's say, I have an URL like the one below:
/test.php?db=...&table=.../
How to extract the DB name and table name from this URL using PHP and use the result for other query purposes.
If you mean how to parse an existing URL for it's parameters:
parse_url() and parse_str() will help you strip the components of the url. You will primarily be looking at the following
$elements = parse_url($url);
$kvps = $elements->query;
$db = parse_str($kvps['db']);
$table = parse_str($kvps['table']);
But, if you mean how to GET variables from the current page before render:
<?php
$dbname = $_GET['db'];
$tablename = $_GET['table'];
?>
And yea, there are major security risks involved in opening up 'direct' access to your database this way. Best to obfuscate / encapsulate / wrap your functions in tasks like index.php&addUser=tim instead of index.php&insert=tim&db=boofar&table=users&dbuser=root&dbpassword=secure.
If you're just learning, what you're doing is fine, as long as you realize why it's wrong. If you're coding for production, you really need an alternate solution.
There are two ways to pass variables or data to another page.
GET (via the URL)
and
POST (usually a form submission)
You can alway get via
$_GET

or
$_POST

In Short, I am pulling the feed from my blogger using the Zend API in PHP. I need to get the URL that will link to that post in blogger. What is the order of functions I need to call to get that URL.
Right now I am pulling the data using:
$query = new Zend_Gdata_Query('http://www.blogger.com/feeds/MYID/posts/default');
$query->setParam('max-results', "1");
$feed = $gdClient->getFeed($query);
$newestPost = $feed->entry[0];
I can not for the life of me figure out where I have to go from here to get the URL. I can successfully get the Post title using: $newestPost->getTitle() and I can get the body by using $newestPost->getContent()->getText(). I have tried a lot of function calls, even ones in the documentation and most of them error out. I have printed out the entire object to look through it and I can find the data I want (so I know it is there) but the object is too complex to be able to just look at and see what I have to do to get to that data.
If anyone can help me or at least point me to a good explanation of how that Object is organized and how to get to each sub object within it, that would be greatly appreciated.
EDIT: Never mind I figured it out.
You are almost there, really all you need to do is once you have your feed entry is access the link element inside. I like pretty URLs so I went with the alternate rather than the self entry in the atom feed.
$link = $entry->link[4]->href;
where $entry is the entry that you are setting from the feed.
The solution is:
$query = new Zend_Gdata_Query('http://www.blogger.com/feeds/MyID/posts/default');
$query->setParam('max-results', "1");
$feed = $gdClient->getFeed($query);
$newestPost = $feed->entry[0];
$body = $newestPost->getContent()->getText();
$body now contains the post contents of the latest post (or entry[0]) from the feed. This is just the contents of the body of the post, not the title or any other data or formatting.
OK, here's my dilemma:
I've read all over about how many guys want to be able to display a set of images from Flickr using PHPFlickr, but lament on how the API for PhotoSets does not put individual photo descriptions. Some have tried to set up their PHP so it will pull the description on each photo as the script assembles the gallery on the page. However, the method has shown how slow and inefficient it can be.
I caught an idea elsewhere of creating a string of comma separated values with the photo ID and the description. I'd store it on the MySQL database and then call upon it when I have my script assemble the gallery on the page. I'd use explode to create an array of the photo ID and its description, then call on that to fill in the gaps...thus less API calls and a faster page.
So in the back-end admin, I have a form where I set up the information for the gallery, and I hand a Set ID. The script would then go through and make this string of separated values ("|~|" as a separation). Here's what I came up with:
include("phpFlickr.php");
$f = new phpFlickr("< api >");
$descArray = "";
// This will create an Array of Photo ID from the Set ID.
// $setFeed is the set ID brought in from the form.
$photos = $f->photosets_getPhotos($setFeed);
foreach ($photos['photoset']['photo'] as $photo) {
$returnDesc = array();
$photoID = $photo['id'];
$rsp = $f->photos_getInfo($photoID);
foreach ($rsp as $pic) {
$returnDesc[] = htmlspecialchars($pic['description'], ENT_QUOTES);
}
$descArray .= $photoID."|~|".$returnDesc[0]."|~|";
}
The string $descArray would then be placed in the MySQL string that puts it into the database with other information brought in from the form.
My first question is was I correct in using a second foreach loop to get those descriptions? I tried following other examples all over the net that didn't use that, but they never worked. When I brought on the second foreach, then it worked. Should I have done something else?
I noticed the data returned would be two entries. One being the description, and the other just an "o"...hence the array $returnDesc so I could just get the one string I wanted and not the other.
Second question is if I made this too complicated or not. I like to try to learn to write cleaner/leaner code, and was looking for opinions.
Suggestions on improvement are welcome. Thank you in advance.
I'm not 100% sure as I've just browsed the source for phpFlickr, and looked the the Flickr API for the getInfo() call. But let me have a go anyway :)
First off, it looks like you shouldn't need that loop, like you mention. What does the output of print_r($rsp); look like? It could be that $rsp is an array with 1 element, in which case you could ditch the inner loop and replace it with something like $pic = $rsp[0]; $desc = $pic['description'];
Also, I'd create a new "description" column in your database table (that has the photo id as the primary key), and store the description in their on its own. Parsing db fields like that is a bit of a nightmare. Lastly, you might want to force htmlspecialchars to work in UTF8 mode, cause I don't think it does by default. From memory, the third parameter is the content encoding.
edit: doesn't phpFlickr have its own caching system? Why not use that and make the cache size massive? Seems like you might be re-inventing the wheel here... maybe all you need to do is increase the cache size, and make a getDescription function:
function getDescription ($id)
{
$rsp = $phpFlickr->photos_getInfo ($id);
$pic = $rsp[0];
return $pic['description'];
}
