Javascript function onclick

Question

I am trying to call a jquery script that will post data to a PHP form. Been googling this for 5h now but i cant seems to solve it on my own. The Script looks like this.

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script language="JavaScript" type="text/javascript">
 function postscrape(igid, iguser, groupid) {
 alert(igid);
 $.post("scrapeadder.php", {
 instagramid: igid,
 username: iguser,
 groupid: groupid
 },
 function(data, status) {
 alert("Data: " + data + "\nStatus: " + status);
 });
 };
</script>

And my HTML/PHP code to call this function looks like:

 echo '<td><button type="button" class="btn btn-success datascraper" name="addscrape" id="addscrape" onclick="postscrape('.$row["instagram_id"].', '.$row["user_name"].', 1);">Add to Scrape</button></td>';

The error i get is: Uncaught ReferenceError: X is not defined

Where X = The iguser (which gets from $row["user_name"] If i check the HTML code on the homepage it list all the $rows correct. So my guess is i messed up in the function.

• adeneo: Maybe you should post the code that contains the error instead ?
• M H: I second that request
• ShapCyber: are you able to print out the $row["instagram_id"].', '.$row["user_name"] and sure that there valid
• Zara Rebecka Elisabeth Zentio: Yes, when i check the source code in my webbrowser i can see the correct values in all those variables.
• epascarello: Always look at the clientside code generated by the serverside. Do not debug from looking at server code when it is a JS error.

Answer 1

You need to put the user name in quotes.

onclick="postscrape('.$row["instagram_id"].', \''.$row["user_name"].'\', 1);"

Answer 2

You didn't quote the user name. The

echo 'postscrape('.$row["user_name"].')' 

yields

postscrape(X)

...where X is undefined.
