Uncaught SyntaxError: JSON.parse: unexpected character ierror after include php file-CodePudding

Uncaught SyntaxError: JSON.parse: unexpected character at line 1 column 2 of the JSON data site:stackoverflow.com error is showing in firefox debug console.

I have a form in my website and on submit button this functions calls

$("#contact-form").on("submit",function(e)
  {
    var sendData = $(this).serialize();
    e.preventDefault();

    if ( checkSubmitInputs(this)  )
    {
      $.ajax({
        type: "POST",
        url: "js/ajaxsubmit.php",
        data: sendData,
        success: function(data)
        {
          $("#loading-img").css("display","none");
          // $(".response_msg").text(data);
          // document.getElementById('contact-form').style.display = 'none'
          // document.getElementById('success').style.display = 'block'
          



          data = JSON.parse(data);
          if(data.status){
            document.getElementById('contact-form').style.display = 'none';
            $("#error").text('');
            $("#success").text(data.msg); 
            document.getElementById('success').style.display = 'block';
            document.getElementById('scicon-c').style.display = 'block';
            document.getElementById('error').style.display = 'none';
            $("#contact-form").find("input[type=text], input[type=email], textarea").val("");
          }
          else {
            document.getElementById('contact-form').style.display = '';
            $("#success").text(''); 
            $("#error").text(data.msg); 
            document.getElementById('error').style.display = 'block'
            document.getElementById('success').style.display = 'none'
            document.getElementById('scicon-c').style.display = 'none'
          }
              
        }
      });
    } else{
        document.getElementsByClassName('error').style.display = 'block'
    }
  })

This line data = JSON.parse(data); shows above error as soon as i add include_once('mail.php'); in my ajaxsubmit.php file and without including it works perfectly.

Mail.php I am receiving mail too

    }

    echo json_encode($response);
?>

As i said everything is working if i don't add require in ajaxsubmit file. I am not good in php or JS so after reading so many answers i still can't figure out why i am not able to parse json at my form.

This is JSON Returned by AJAXsubmit

{
    "status": true,
    "msg": "Thank you Demo. Welcome in SAAS Application. We will connect with you soon. :)"
}

CodePudding user response：

Your problem is that mail.php has this code in it:

    try {
        $mail->send();
        echo "Message has been sent successfully";
        return true;
    } catch (Exception $e) {
        echo "Mailer Error: " . $mail->ErrorInfo;
        return false;
    }

which, regardless of the result, causes text to be echo'ed. As a result, your json response will look something like:

Message has been sent successfully
{
 ... normal json response
}

which will not parse successfully.
