[SOLVED] Confirm Box?

ayok · September 24, 2007

Hi there,

I have a question regarding the confirm box of javascript. I'd like to pop up a confirm box when the admin wants to delete an item.

So when the person click on "ok", the item will be delete, but if "cancel" is clicked, then it would stay on this page. But I cannot get it works.

I've tried this script:

<script type="text/javascript">
function disp_confirm(){
    var name=confirm("You're going to delete this item, would you like to process it?")
    if (name==true){
        window.location("delete.php?id=$data[id_cat];")
    }
}
</script>

And this code on the delete:

<a href='' onclick='disp_confirm()'>delete</a>

Could anybody help me with this?

Thank you,

ayok

If you want to cancel the default event you need to return either true or false from the event handler. I forget which value (true, false) is used to cancel the default action associated with the onclick event. Just try one and then the other.

Hi roopurt,

Sorry I don't understand your answer. Could you give me example?

function disp_confirm(){

var name=confirm("You're going to delete this item, would you like to process it?")

if (name==true){

window.location("delete.php?id=$data[id_cat];")

}else{

return true; // change true to false if it doesn't work

}

</script>

Hi thanks roopurt,

It is return to the page when i click "cancel", but it doesn't delete when i click on "ok".

Is there something wrong with the window location?

I think it's supposed to be:

window.location.href = <rvalue>;

I think it's supposed to be:

window.location.href = <rvalue>;

Thanks roopurt,

It seems the javascript is working, but i can't get the url "delete.php?id=$data[id_cat];"

Is there any help to correct this?

What does the URL look like after you click the delete link and then click OK to confirm?

ayok · September 24, 2007

It goes to index.php.. its an admin folder.. www.myweb.com/admin/

It would be hard to say what's going on without seeing some more of your code.

Or you can try changing the line:

window.location("delete.php?id=$data[id_cat];")

to

window.location.href="http://www.yahoo.com/"

Just to make sure it's redirecting correctly when you press OK.

ayok · September 24, 2007

No.. it doesn't go to yahoo.com. So it goes to empty url.

Hi,

So far my javascript is:

function disp_confirm(){
    var name=confirm("Do you really want to delete this?")
    if (name==true){
        window.location("delete.php?id=$data[id_cat]")
    }
    else{
	return true;
	}
}

and the link where to click:

<a href='' onclick='disp_confirm()'>delete</a>

The confirm box is popuped but if i click on ok or cancel it will open the index page. Anybody can help me?

Thank you,

ayok

You don't call window.location as if it's a function. Do you see any difference at all between the following?

// wrong!
window.location("delete.php?id=$data[id_cat];")

// correct!
window.location.href = "http://www.yahoo.com";

ayok · September 25, 2007

Hi roopurt,

I have try the code

window.location.href = "http://www.yahoo.com";

. But it doesn't go to yahoo.com. It stays in the same page.

thank you,

ayok

roopurt18 · September 25, 2007

Try this:

function disp_confirm(){
    var msg = "Do you really want to delete this?";
    if (confirm(msg)){
        window.location("delete.php?id=$data[id_cat]");
        return false;
    }
    else{
	return true;
	}
}

Hi roopurt,

It still doesn't work. I try in IE it gives an error: Object doesn't support this action.

thanks,

<html>
<head>
<script type="text/javascript">
function disp_confirm(){
    var msg = "Do you really want to delete this?";
    if (confirm(msg)){
        window.location.href = "http://www.yahoo.com";
    }
    return false;
}
</script>
</head>
<body>
  <a href='' onclick='return disp_confirm();'>delete</a>
</body>
</html>

Hi roopurt,

After I tried with html page, it works. So I think the problem is that I'm doing it in php script.

Is there anyway to use it in php script. Because the item that will be deleted is in php.

thank you,

ayok

roopurt18 · September 25, 2007

Post your PHP script.

ayok · September 25, 2007

<?php
$show = mysql_query("SELECT service.*,category.name FROM service LEFT JOIN category on service.category=category.id_cat WHERE category='$id'") or die(mysql_error());
echo "<table border=0><tr bgcolor='#D0DCE0'><th>Service</th><th>Description</th><th>Duration (minutes)</th><th>Prices</th></tr>";


    while (($data = mysql_fetch_array($tampil)) && (mysql_num_rows($tampil) > 0))
    {
        echo "<tr>";
        echo "<td bgcolor='#D47FFF'>$data[name_serv]</td>";
        echo "<td bgcolor='#FF55FF'>$data[desc_serv]</td>";
        echo "<td bgcolor='#D47FFF'>$data[minutes]</td>";
        echo "<td bgcolor='#FF55FF'>$data[price]</td>";
        echo "<td><a href='' onclick='disp_confirm()'>delete</a><br><a href=edit_service.php?id=$data[id_serv]>edit</a></td></tr>";
    }
    echo "</table>";
}?>

<script type="text/javascript">
function disp_confirm(){
    var msg = "Do you really want to delete this?";
    if (confirm(msg)){
        window.location("delete.php?id=$datakategori[id_cat]");
    }
    return false;
}
</script>

roopurt18 · September 25, 2007

Is $datakategori[id_cat] a global PHP variable?

ayok · September 25, 2007

Sorry, I missed some lines above it

<?php
$show1 = mysql_query("SELECT * FROM category WHERE id_cat='$id'") or die(mysql_error());
$datakategori = mysql_fetch_array($show1);
echo "<H3>$datakategori[name]</H3><br><img align='left' src='../pics/$datakategori[pic]'<br><H5>$datakategori[description](<a href=edit_cat.php?id=$datakategori[id_cat]>edit kategori</a> | <a href=add_cat.php>add kategori</a>)<H5>";

$show = mysql_query("SELECT service.*,category.name FROM service LEFT JOIN category on service.category=category.id_cat WHERE category='$id'") or die(mysql_error());
echo "<table border=0><tr bgcolor='#D0DCE0'><th>Service</th><th>Description</th><th>Duration (minutes)</th><th>Prices</th></tr>";


    while (($data = mysql_fetch_array($tampil)) && (mysql_num_rows($tampil) > 0))
    {
        echo "<tr>";
        echo "<td bgcolor='#D47FFF'>$data[name_serv]</td>";
        echo "<td bgcolor='#FF55FF'>$data[desc_serv]</td>";
        echo "<td bgcolor='#D47FFF'>$data[minutes]</td>";
        echo "<td bgcolor='#FF55FF'>$data[price]</td>";
        echo "<td><a href='' onclick='disp_confirm()'>delete</a><br><a href=edit_service.php?id=$data[id_serv]>edit</a></td></tr>";
    }
    echo "</table>";
}?>

<script type="text/javascript">
function disp_confirm(){
    var msg = "Do you really want to delete this?";
    if (confirm(msg)){
        window.location("delete.php?id=$datakategori[id_cat]");
    }
    return false;
}
</script>

roopurt18 · September 26, 2007

The problem is that you're trying to set the $_GET parameter in the Javascript but you are not in PHP mode (because you've stepped out of PHP with the ?>).

<script type="text/javascript">
function disp_confirm(){
    var msg = "Do you really want to delete this?";
    if (confirm(msg)){
        window.location.href = "delete.php?id=<?php echo $datakategori['id_cat'];?>";
    }
    return false;
}
</script>

ayok · September 26, 2007

Hi roopurt,

its the same. it doesnt go to delete.php.

The problem is, it results the same if I set the window location to yahoo.com, except I did it in html page.

thank you,

ayok

roopurt18 · September 26, 2007

Perhaps change the target location to an absolute URL? I'm not sure why it wouldn't work at this point.
