[RESOLVED] htmlentities question

[ncracraf]

I have a parent/child page on my site. The parent section simply lists the ID and Title of the parent. The child portion includes a form for adding child records to the parent. There are two buttons on the child form: Submit and New.

The Submit button posts the form for insertion or update in the database. The New button clears the form values to allow entering a new record.

The code I use for the New button is as follows:

  // Check if the New button has been clicked and if it has,
  // redirect to the same page but with only the parent ID.  This
  // will allow the user to add a new record without leaving the page
  if (isset($_POST['New'])) {
    header("Location: " . $_SERVER['PHP_SELF'] . "?par_id=" . $_GET['par_id'] ) ;
    exit;
  }

After clicking the New button, some users (and only some of the time) receive the error message:

Sorry, we couldn't find http://www.anysitename.com/link_manage.php%3Fid. Here are some related websites:

This is a message on DELL computers when it can't resolve the address.
I have a DELL machine myself and have never gotten this message.

My question is, do I need to enclose my redirect with htmlentities? Could this be the issue? I'm confused since the error only appears occasionally.

Thanks.

Could you use an HTML <input type="reset"> button instead?

Just curous...

Actually, you have a great point. At one point in time I had a reason for using this approach as opposed to the reset type. For the life of me, I can't remember why.

Nonetheless, I have other header redirects with the same formatting as the one included in the original comment. Was wondering if the same issue is going to appear with these links and whether or not I need to use htmlentities around them.

I've been researching the htmlentites function and haven't found when you need to or not use it.

Thanks for the feedback.

Hi.

I'm interested in the code you have written and wonder if i could use the same to preview submitted data. Assuming i can could you please indicate what par id means or is it just a record id?
Thanks.

Basically, i'm thinking of changing the code to something like

if (isset($_POST['Preview'])) { 
    header("Location: " . $_SERVER['PHP_SELF'] . "?enquiryid=" . $_GET['enquiryid'] ) ; 
    exit; 
  } 

Thanks again for your guidance.

Hi,

Unfortunately I can't directly share the code as it has some confidential data in it. However, if you let me know what area you need help with, I could certainly provide you sanitized snippets or pseudocode.

There are three components to the parent-child page. The first is the parent record information such as ID, title, description, etc. The second component is an edit form for the child data. The third component (which is optional but quite useful) is a listing of all the child records for that parent. As soon as you add a child in the second component, it is displayed in the third component (listing).

To answer your question, par_id is the ID of the parent in the first component. It's included as a $_GET so that, each time the user adds or updates a child record in the second component, the page is refreshed by loading the parent record (par_id) and associated children.

Let me know what specific areas of the code you need help with and I'd be happy to send you samples.

Marking this one resolved. I haven't heard of these issues on any but a couple computers in the same household. Perhaps an issue with their ISP.
