I have a form that contain a input field that I populate with a date/time picker.  If you populate the form on the server with some default values, the jQuery’s hidden fields wont get set unless you do some action on the calendar.

The  solution  is to add inline:true to its options like this:

$(“#myDate”).datepicker({

inline: true,
dateFormat: ‘yy-mm-dd’

});

Source : here

$headers[] = 'Connection: Keep-Alive';
$headers[] = 'Content-type: application/x-www-form-urlencoded';
$headers[] = 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8';
$headers[] = 'Accept-Charset: utf-8;';
$headers[] = 'Keep-Alive: 300';

dupa setarea aray-ului cu header-ele, acesta trebuie integrat in CURL

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,'http://www.google.ro/search?&q='.urlencode($val['keywords']));
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookieFilenameLogin);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookieFilenameLogin);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.5) Gecko/2008120122 Firefox/3.0.5");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true );
curl_setopt($ch, CURLOPT_HEADER,0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_ENCODING, 'gzip,deflate');
curl_setopt($ch, CURLOPT_FAILONERROR, 1);
$data = curl_exec($ch);
curl_close($ch);

Editing functionality is applied to selected page content through scripts that apply the document.execCommand() method. Parameters are passed to this method giving the edit command to apply. The general format for the execCommand() method is shown below. It is applied through the document object.

document.execCommand("command" [,0] [,"value"])

<button title="Bold"
  onclick="document.execCommand('Bold')">
  <img src="Bold.gif"/>
</button>

Editing Commands

All of the available editing commands are too numerous to list here. The following table gives a sampling of what types of editing can be applied to selected text a page.

Va returna Boolean, iar in cazul TRUE va salva un jpeg cu watermark din imaginea initiala. Functia se foloseste de libraria GD inclusa in php si accepta orice fel de tip de imagine pe care o poate recunoaste aceasta.

Watermarkul este pus in coltul din dreapta jos, dar asta se paote modifica dupa bunul plac.

function set_watermark($source, $dest, $watermark, $quality = 80)
{
  if (func_num_args() < 3)
  {
    $set_watermark_error = "Insufficient parameters supplied!";
  }
  else
  {
    if (file_exists($source))
    {
      if ($src = imagecreatefromstring(file_get_contents($source)))
      {
        $info = getimagesize($source);
        imageantialias($src, true);
        if ($wm = imagecreatefromstring(file_get_contents($watermark)))
        {
          $wm_info = getimagesize($watermark);
          imagealphablending($src, true);
          imagecopy($src, $wm, $info[0]-$wm_info[0]-5, $info[1]-$wm_info[1]-5, 0, 0, $wm_info[0], $wm_info[1]);
          if (imagejpeg($src, $dest, $quality))
          {
            if (file_exists($dest))
            {
              chmod($dest, 0777);
              return true;
            }
            else
            {
              $set_watermark_error = 'Unable tosaveimage! ';
            }
          }
          else
          {
            $set_watermark_error = 'Unable tosaveimage! ';
          }
        }
      }
      else
      {
        $set_watermark_error = 'Unrecognized imageformat! ';
      }
    }
    else
    {
      $set_watermark_error = 'Source filedoesnotexist! ';
    }
  }
  return false;
