MySQL Question

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.php?id_noticia=<?php echo $id ?>">Editar</a>

And then a
on the other page.

However, this is not how I desire my editing window.
Therefore, I have been exploring a way to send the PHP variable that contains the primary key for the news table (MySQL) to a popup window, using JavaScript. But that's just the thing, it will only return the 1st value it gets from the query... (i.e If I click to edit the 3rd article, it edits my 1st one. Always.)

Here is my current code:

<div class="noticias">
mysql_select_db($bd, $conn);

$resultado = mysql_query("SELECT * FROM noticia INNER JOIN user ON noticia.id_user=user.id_user ORDER BY id_noticia DESC");

while ($linha = mysql_fetch_array($resultado)) {
echo "<h1>" . $linha['titulo'] . "</h1>";
echo "<i>Posted by " .$linha['username']. " on " . "<y>" . $linha['data'] . "</y>" . "</i>";
echo "<p>";
echo $linha['texto'];

$id = $linha['id_noticia'];

if (isset($_SESSION['admin'])) {
<div class="noticiasOpcao">
<a href="" onClick="open_win_editar()">Editar</a>
<a onclick="return confirm('Are you sure?')" href="noticiaApagar.php?id_noticia=<?php echo $id ?>">Apagar</a>

<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"

<?php mysql_close($conn); ?>


My point is to then use another query to get the title and text of the article to display on an WYSIWYG editor.

Can anyone point out my flaw?


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");

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");

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.
