Javascript And PHP (window.open)

So, in my website, I have a news system which has an option to edit and delete the news the administrator desires. Well, I got the edit part right by using: href='noticiaEditarForm

Solution 1:

This code:

<script language="javascript">
    function open_win_editar() {
        window.open ("noticiaEditarForm.php?id_noticia=<?php echo $id; ?>", "Editar notícia", "location=1, status=1, scrollbars=1, width=800, height=455");
     }
</script>

Is happening outside of the PHP while loop, so the value of $id will be the last value that was set to $id in the loop. So the JavaScript code will always open the same link.

If you need the code within the PHP loop to specify the $id value for the JavaScript, then you can pass it as an argument to the JavaScript function. Something like this:

<script language="javascript">
    function open_win_editar(targetID) {
        window.open ("noticiaEditarForm.php?id_noticia=" + targetID, "Editar notícia", "location=1, status=1, scrollbars=1, width=800, height=455");
     }
</script>

So the code rendering the anchor tags in the loop would pass the argument like this:

<a href="" onClick="open_win_editar(<?php echo $id; ?>)">Editar</a>

The rendered output would then contain the record-specific $id value on each a tag to be used by the JavaScript code on the client.

Solution 2:

The id of the piece to edit is only updated within the while loop and never outside of it.

To use it as you wish you should use a parameter for the open_with_editar function:

<script language="javascript">
            function open_win_editar(id) {
                window.open ("noticiaEditarForm.php?id_noticia="+id, "Editar notícia", "location=1, status=1, scrollbars=1, width=800, height=455");
            }
        </script>

Now you only have to update the onclick event and hand over teh respective id:

<div class="noticiasOpcao">
      <a href="" onClick="open_win_editar(<?php echo $id; ?>)">Editar</a>

That should work.
