Question

I have a function that returns a json encoded response from a $_POST:

function getdatafrompost(){
    $raw  = '';     
    $httpContent = fopen('php://input', 'r');
    while ($kb = fread($httpContent, 1024))
        $raw .= $kb;        
    fclose($httpContent);      
    $params = array();
    parse_str($raw, $params);
    if (isset($params['data'])) 
        $retdata = json_decode(stripslashes($params['data']));
    else
        $retdata = json_decode(stripslashes($raw)); <====Returns Null
    return $retdata;
}

The raw data being read is:

{"recordid":"099ac8aa-0a43-11e2-860f-0016177c526f","ntsdataid":"","trkdataid":"5628af8e-08db-11e2-860f-0016177c526f","activitydate":"2012-09-29","activitytime":"10:36:21","activityname":" from S. Interrante","activitynote":"<i><font color=\"99CC00\" size=\"4\"><b><font face=\"verdana\">fgsdfgsdgsdfgsdgsdgsdfg</font>\u200b</b></font></i>"}

The problem is $retdata is returning null. This appears to be in the “activitynote” field, which contains HTML. When “activitynote” contains no HTML then data is parsed properly. Is there a better approach to parsing the data? Am I doing something incorrectly?

Answer 1

You are not supposed to use stripslashes , it would affect the validity of the json document to fix this error you should replace

json_decode(stripslashes($raw))

With

json_decode($raw);

Example

$raw = '{"recordid":"099ac8aa-0a43-11e2-860f-0016177c526f","ntsdataid":"","trkdataid":"5628af8e-08db-11e2-860f-0016177c526f","activitydate":"2012-09-29","activitytime":"10:36:21","activityname":" from S. Interrante","activitynote":"<i><font color=\"99CC00\" size=\"4\"><b><font face=\"verdana\">fgsdfgsdgsdfgsdgsdgsdfg</font>\u200b</b></font></i>"}' ;
var_dump(json_decode($raw));

Output

object(stdClass)[1]
  public 'recordid' => string '099ac8aa-0a43-11e2-860f-0016177c526f' (length=36)

  public 'activitytime' => string '10:36:21' (length=8)
  public 'activityname' => string ' from S. Interrante' (length=19)
  public 'activitynote' => string '<i><font color="99CC00" size="4"><b><font face="verdana">fgsdfgsdgsdfgsdgsdgsdfg</font>​</b></font></i>' (length=105)
