[Zend Switching View/Multiple Output Formats]

Hi,

I'm developing a mobile site that needs to be able to use either XHTML or WML, depending on the device capabilities.

I'd like to keep the same controllers and models, but am unsure of the best way to achieve switching the output format.

The way that seems logical would be to switch views. I can't see how to do this, though, and I'm not certain it's the best practice.

The other option I can think of would be to have logic in the view to decide which to output, but that seems very messy.

Any advice is appreciated, thanks!

[[SOLVED] SimpleXML catching 404]

Thanks a lot!

[[SOLVED] %22]

I don't have time to look through your code at the moment, but %22 is the url entity for a double quote (").

See if a double quote is sneaking into your url somewhere. you can also use url_decode to change it back to a quote.

[[SOLVED] SimpleXML catching 404]

I'm building a script with the last.fm datafeeds.

 

When a incorrect username is given to the script, the last fm site throws a 404, and results in this PHP error:

 

Warning: simplexml_load_file(http://ws.audioscrobbler.com/1.0/user/RichardJohn/tasteometer.xml?with=) [function.simplexml-load-file]: failed to open stream: HTTP request failed! HTTP/1.0 404 Not Found in /home/richardm/public_html/lastfmcompatibility.php on line 12

Warning: simplexml_load_file() [function.simplexml-load-file]: I/O warning : failed to load external entity "http://ws.audioscrobbler.com/1.0/user/RichardJohn/tasteometer.xml?with=" in /home/richardm/public_html/lastfmcompatibility.php on line 12
There was a problem loading the data feed.

 

Is there a way to catch this error and just present a friendly error?

[Paypal IPN]

How do I tell PayPal to ping the script, and I also need to know how I give Paypal a variable for it to pass back when the payment is complete.

Thanks.

[Paypal IPN]

I'm creating a site for someone else that needs to use Paypal.
Basically, the script submits the entry to the database with a paid value of 0 (This I can do myself), then the person pays with paypal, and Paypal IPN should ping a script which changes the paid value to 1.

Does anyone know any tutorial/script that can do this, as it's really frustrating, there seems to be no decent documentation anywhere! It also complicates things that it's not my Paypal account.

Best Wishes,
Richard John

[Checking variables]

I have a form that's submitting all of the variables by post.
I'm using this code to remove htmk/javascript and tocheck that they're not empty:

$poster = $_POST['poster'];
$cityid = $_POST['cityid'];
$catid = $_POST['catid'];
$subcatid = $_POST['subcatid'];
$showphone = $_POST['showphone'];

if($showphone=="on") {
$showphone = 1;
} else {
$showphone = 0;
}

$title = $_POST['catid'];
$title = strip_tags($title);
$title = RemoveXSS($title);

$body = $_POST['body'];
$body = strip_tags($body);
$body = RemoveXSS($body);

$location = $_POST['location'];
$location = strip_tags($location);
$location = RemoveXSS($location);

$price = $_POST['price'];
$price = strip_tags($price);
$price = RemoveXSS($price);

$phone = $_POST['phone'];
$phone = strip_tags($phone);
$phone = RemoveXSS($phone);

$email = $_POST['email'];
$email = strip_tags($email);
$email = RemoveXSS($email);

if($cityid=="") {
header("location: post.php?err=cityid");
}
if($catid=="") {
header("location: post.php?err=catid");
}
if($title=="") {
header("location: post.php?err=title");
}
if($body=="") {
header("location: post.php?err=body");
}
if($location=="") {
header("location: post.php?err=location");
}
if($phone=="") {
header("location: post.php?err=phone");
}
if($email=="") {
header("location: post.php?err=email");
}

Every time the script is run, it returns to the form with the blank email error. I've triple-checked the form field's name. EVen if I leave all of the other fields blank, it still goes back on the email. Anyone got any ideas?

[Thumbnails with cache.]

Thanks, but that code is almost exactly the same, apart from the fact the one I'm using checks the file extension too.

[Thumbnails with cache.]

I've also tried this with other paths as tthe image, like ../images/$num.jpg and /images/$num.jpg but it just refuses to save, there are no errors, it just wont save.

[Thumbnails with cache.]

I've been using a script that wasn't writtenn by me for a while to create thumbnails of logos on the fly.
This is now taking too long with 30+ logos on a page, so i've decided to implement a cache.
When I execute this script, it creates a thumbnail of the image, displays it in the browser, but does not save it. This means the cache does not work at all. I've also tried using fopen and fwrite, but I can't get the image to save.
The images folder is CHMOD 777.

[code=php:0]
<?php

header("Content-Type: image/jpeg");

$num = $_GET['num'];

$image_path = "http://www.radioo.net/images/$num.jpg";

if (file_exists($image_path)) {

readfile($image_path);
}else{

  if (isset($_GET['img'])) {

        // Generate a thumbnail of the image
        if (!isset($_GET['iw'])) { $iw = 50; } else { $iw = $_GET['iw']; }
        $iname = $_GET['img'];
        if (ereg('png$',$_GET['img'])) {    $i = imagecreatefrompng($iname); }
        if (ereg('jpg$',$_GET['img'])) {    $i =
imagecreatefromjpeg($iname); }
        if (ereg('gif$',$_GET['img'])) {    $i = imagecreatefromgif($iname); }
        if (imageSX($i) <= $iw) {
            imagejpeg($i);
        } else {
            $i2 =
imagecreatetruecolor($iw,($iw*(imagesy($i)/imagesx($i)))+1);

imagecopyresampled($i2,$i,0,0,0,0,$iw,$iw*(imagesy($i)/imagesx($i))+1,imagesx($i),imagesy($i));


          imagejpeg($i2);
          imagejpeg($i2,$image_path);
       

ImageDestroy($i2);

        }
        exit;
    }


}

?>
[/code]

Any help appreciated, thanks.

[submitting POST request]

If you can (with a Firefox extension), look at the headers after you've submitted the form to see if the problem lies in the form, or the php.

[Sessions]

I have a problem with sessions.
All the links on my site are prefixed with www.
I've just implemented a registration system, but I'm having a problem with sessions.
If the user visits the site with the www. prefix, the sessions work fine and the user stays logged in, however if the user omits the www. from the address, the user gets logged out when clicking a link.

How can I either solve this, or forward all users to www.?

[Tag Clouds]

I think it's the code snippet on the Hawkee site that's confusing me. I just can't get my head around the way the array is supposed to be structured for it.

[Tag Clouds]

Using this code (so I can see the array) gives me the error:
Parse error: parse error, unexpected T_ARRAY, expecting T_STRING or T_VARIABLE or '$' in /home/radioone/public_html/tagsave.php on line 7

[code]

$tags_arr = explode(",",$tags);


$tags_count = new array();

foreach ($tags_arr as $tag){
     if (array_key_exists($tag, $tags_count)){
          $tags_count[$tag]++;
     }
     else {
          $tags_count[$tag] = 1;
     }
}

print_r(array_keys($tags_count));[/code]

The variable "tags" contains all of the tags seperated by commas.

[Tag Clouds]

Thank you for the reply.

How do I actually get the count, though?

The tags have not been counted, there are just multiple instances of them in the array.

[[SOLVED] Page Location Script]

If what you're looking to do is re-direct based on parameters (such as index.php?location=forums redirects to forums.php) then this should do it:

<?

$location = $_GET['location'];

if($location=="PAGENAME") {
header("location: pagename.php");
}
else if($location=="OTHERPAGENAME") {
header("location: otherpagename.php");
}

etc.

[Tag Clouds]

Hello,
I need to tag clouds for a site I am working on, but I can't quite get my head around it!

I've found a code snippet that distribues the font sizes, but that does not include how to count the tags in the first place to get it to work! (the snippet is this one [a href=\"http://www.hawkee.com/snippet.php?snippet_id=1485)\" target=\"_blank\"]http://www.hawkee.com/snippet.php?snippet_id=1485)[/a]

In my database I have the tags in a field seperated by spaces for each record (I know this was a bad way of doing it, but it can't be changed now). I have no problem taking all the tags from the database, and putting them into an array, but after this, I can't work out how to count the tags and turn it into a tag cloud!

So I have an array full of tags, but I can't work out how to do anythign with it!

Any help/ideas appreicated!
