Using Json_Decode To Create An Array

[Xtremer360]

I'm trying to figure out why when it shows the listing of attachments when its not NULL that it displays them as a string and NOT as an array. That way after it checks to see if its a file and returns TRUE for the function then it makes it array after all the attachments have been gone through.

 

$attachments = json_decode($attachments, TRUE);
for ($x = 0; $x < count($attachments); $x++)
{
   $file_name = $attachments[$x];
   if ($this->functions_model->is_file('assets/downloads/'.$file_name, FALSE) === TRUE)
   {
    $message_data->attachments = $file_name;           	
   }  
}

I've also tried this however its not adding the second key is_file regardless of if its TRUE or FALSE

$attachments = json_decode($attachments, TRUE);
               for ($x = 0; $x < count($attachments); $x++)
               {
                   $file_name = $attachments[$x];
                   if ($this->functions_model->is_file('assets/downloads/'.$file_name, FALSE) === TRUE)
                   {
                       $attachments[$x]['is_file'] = TRUE;
                   }
                   else
                   {
                       $attachments[$x]['is_file'] = FALSE;
                   }
               }

$file_name = $attachments[$x];

 

That line implies $attachments[$x] is a string

 

 

$attachments[$x]['is_file'] = TRUE;

 

In that line, you use $attachments[$x] as an array.

 

Which is it?

I have a better question that deals with this sort of issue. I'm getting an error that consists of...

 

 

A PHP Error was encountered

 

Severity: Notice

Message: Undefined property: stdClass::$datetime_sent
