json_encode not working with a html string as value

Question

I am debugging this ajax for quite a time now. I have this on my jQUery file:

$(\"#typeForm\").ajaxForm({
    success : function(html){
        alert(html);
         


        

Answer 1

JSON doesn't play well with string output that comes out of magic method __toString() - it nearly impossible to json_encode() anything that even remotely touched something like this.

<?php
/**
 * DEBUGGING NIGHTMARE
 * SO MUCH FUN, 10/10,
 */
class Nightmare {
  protected $str;
  public function __construct($str) {
    $this->str = $str;
  }
  public function __toString() {
    return $this->str;
  }
}

$test = new Nightmare('Hello Friends.');
echo $test;
> Hello Friends.

// cooool, so let's JSON the hell out of it, EASY

echo json_encode(['our_hello' => $test]);
// This what you expect to get, right?
> {"our_hello":"Hello Friends."}

// HAHA NO!!!
// THIS IS WHAT YOU GET:
> {"our_hello":{}}


// and this is why is that:

var_dump($test);
object(Nightmare)#1 (1) {
  ["str":protected]=>
  string(14) "Hello Friends."
}

print_r($test);
Nightmare Object
(
    [str:protected] => Hello Friends.
)

You should call only prompt object of your array not all! like below:

$("#typeForm").ajaxForm({
    success : function(html){
        var obj = $.parseJSON(html);
        alert(obj.prompt);
}).submit();
