• Why isn't this message subject encoded properly? (php mail)

  - by Camran

  I use this code to send an email: $headers="MIME-Version: 1.0"."\n"; $headers.="Content-type: text/plain; charset=UTF-8"."\n"; $headers.="From: $name <$email>"."\n"; mail($to, '=?UTF-8?B?'.base64_encode($subject).'?=', $text, $headers, '[email protected]'); If I use special characters Å Ä Ö from the swedish alphabet, they are not encoded properly, so they turn up like ö for ö. However, this doesn't happen if I change the $to variable to a gmail account email, then they are shown correctly. Anybody got any idea? Thanks UPDATE: When I echo $name, the name is displayed correctly, in utf8, with all special chars nicely shown.

• PHP - Get value of imput box, without a form?

  - by Dodi300

  Hello. Does anyone know how I can get the value of an imput box, without having a form? I want a sumbit button, but instead of submiting a form, I want it to change data in a MySQL database. Something like this maybe? $img1="WHAT DO I PUT HERE?" $idx=1 $sql="INSERT INTO games SET img1='$img1' WHERE id=$idx"; $result=mysql_query($sql); Could I use that code on a "onclick" event? The imput box is named "img1". Thanks for the help!

• access a property via string with array in php?

  - by sprugman

  (This is in drupal, but I don't really think that matters.) I have a big list of properties that I need to map between two objects, and in one, the value that I need to map is buried inside an array. I'm hoping to avoid hard-coding the property names in the code. If I have a class like this: class Product { public $colors, $sizes; } I can access the properties like this: $props = array('colors', 'sizes'); foreach ($props as $p) { $this->$p = $other_object->$p; } As far as I can tell, if each of the properties on the left are an array, I can't do this: foreach ($props as $p) { $this->$p[0]['value'] = $other_object->$p; } Is that correct, or am I missing some clever way around this?

• PHP "header (location)" isnide IFRAME, to load in _top location?

  - by Spoonk

  Hi Webmasters. I have a simple form which is inside IFRAME. When user click on SUBMIT, it redirects to a specific page on my server. The function I use for the redirect is header ('Location: mypage2.html'); exit (); But I want the new page to open in _top location, not inside the same IFRAME that I use. How can I tell the browser to open the new page in _top not inside the IFRAME? Thanks in advance.

• Writing To The Response in Rails? (Like "echo" in PHP)

  - by Yar

  I know that I can do this in Rails: <%="hello" %> but is there any way to do this <% echo "hello" %> and get it to show up in the response? I have tried response.write which almost worked, but did not... Edit: print or puts do not do it, because I do not want to write to the console. I want to write to the browser/HTTP client. Edit: Here is an example: <% unless @research_activities.size == 0 concat(render(:partial => 'list')) end %> Why would I want to include two closing tags just to do that? It reads nicely in code, doesn't it?

• PHP SQL, SELECT corresponding data from 3 tables at once?

  - by user346325

  I have 3 tables, 'u' 'd' 's' 'u' has userid divid 'd' has divid divname 's' has sname primaryuserid secondaryuserid Now what I'd like to do is display a table with rows of the following format userid, divname, sname Plus figure out a way to decipher whether userid is a primary or secondary for this sname table. I'm able to show userid and divname using a left join, but I don't know how I would add a third table? To make it trickier, there can be more than 1 snames for each userid, up to ~20. Is there a way to display 0-20 snames depending on the userid, seperated with commas?

• PHP Passing Data to a Specific Class? (Data Encapsulation)

  - by Adam184

  I've learned that OOP is all about data encapsulation, but what about passing data between classes that have nothing to do with each other (would the below example be worthy of using extends)? class Dog { private $secretVar; public function getSecretVar() { $this->secretVar = 'psst... only for rainbow!'; return $this->secretVar; } } class Rainbow { public function __construct(Dog $Dog) { print_r($Dog->getSecretVar()); } } $Dog = new Dog(); $Rainbow = new Rainbow($Dog); // ... classes that don't need the $secretVar How would you encapsulate $secretVar for only classes Dog and Rainbow? As of now, anyone can call getSecretVar(), and I'm having a hard time allowing that to happen as it seems to defeat the whole point of encapsulation.

  Hi, Sorry if this seems like an easy question, but I've started pulling hair out on this... I have a XML file which looks like this... <VAR VarNum="90"> <option>1</option> </VAR> I'm trying to get the VarNum. So far I've been successful using the follow code to get the other information: $xml=simplexml_load_file($file); $option=$xml->option; I just can't get VarNum (the attribute value I think?) Thanks!
