qr code - Showing Form Results On The Same PHP Page -


I have a form that demands the shutdown of QR code from Google, the user puts them on the website and then results them. Directed on the page, which contains the QR code. I was wondering if there was a way to create QR codes on the same page? I tried to put Google Script on the same page but it does not appear to be working according to the code: 

  & lt; Form method = "post" action = "qr-creation.php" & gt; & Lt; Input type = "text" name = "contractno" /> & Lt; Input type = "submit" value = "get QR code" />

This is Google code: 

  & lt;? $ UrlToEncode = "$ lower"; GeneratedQRwithGoogle ($ urlToEncode); Generate function QRwithGoogle ($ url, $ widthHeight = '500', $ EC_level = 'L', $ margin = '0') {$ url = urlencode ($ url); Echo '& lt; Img src = "http://chart.apis.google.com/chart?chs='.$widthHeight. ' X '. $ WidthHeight. & Amp; amp; cht = qr & amp; chld ='. $ EC_level. '.' $ Margin '& amp; amp; amp; chl ='. $ Url. '' Alt = "QR code "WidthHite =" '. $ WidthHight. '"WidthHite ="'. $ WidthHeight. '"/" Gt; '; }? & Gt;

I have never confused ever in AJX, so any simple help would be appreciated. First, submit the form on the self / same page: 

 
 
 & lt; Form method = "post" action = "samefile.php" & gt;

Then, in the same page, if you received a post request and if so, execute your code: 

  if (empty! ( $ _ POST) ['contract']) {// output QR code here}

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
