• 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!

• 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.

  I currently do: $totalBill = number_format($totalBill, 2); $totalBill = '$'.$totalBill; This does not handle cases though where the total is say 10 cents. It returns "$0.1" which I do not want. Does anyone have a better way?

  - by Joel

  I'm just wondering which method is the most effective if I'm literally just wanting to get the number of rows in a table. $res = mysql_query("SELECT count(*) as `number` FROM `table1`"); $count = mysql_fetch_result($res,0,'number'); or $res = mysql_query("SELECT `ID` FROM `table1`"); $count = mysql_num_rows($res); Anyone done any decent testing on this?
