WWW is not ready downloading yet

Hey guys I am new to Unity, and have a problem downloading a response from my webpage. Basically I have a two textfields which get username and password and register these details to a database. The entries are being added to database fine. But when I try to get a response from my PHP page indicating whether the registration was successful ( 1 meaning successful, 2 meaning unsuccessful) I keep getting an error "WWW is not ready downloading yet". I know that yield will wait for the download to complete but I cannot use this because I am using the OnMouseUp( ) method. Does anyone have any suggestions on how to overcome this problem ? Cheers to anyone who can help. OnMouseUp( ) code below.

Code (csharp):

1. void OnMouseUp(){
2.                
3.         print (post_url);
4.         WWW hs_post = new WWW(post_url);   
5.        
6.         string wassup = hs_post.text;
7.         print (wassup);
8.              

 

OnMouseUp is irrelevant.

Code (csharp):

1.  
2. void OnMouseUp()
3. {
4.     StartCoroutine(DoWWW());
5. }
6.  
7. private IEnumerator DoWWW()
8. {
9.     WWW hs_post = new WWW(post_url);
10.     yield return hs_post;
11.     print(hs_post.text);
12. }
13.  

 

sorry for the late reply thanks for the help it worked a charm

 

I actually use the code with the "yield return www;" but it still returns the same error. I was expecting it to wait but it does not and returns the same error. Any clue?

 

Unity crashes every time it reaches "yield return www". unity 5.3.4

 

Having the same problem in Unity 5.5.1 -- did not use to happen
