[Resolved] Do you really want to do that??

concept0020

I have an admin page that allows the administration to add, update, and delete users from a mysql database. Which works fine.

I was looking for a way to have an alert box open when the delete button is pressed. For example it would say, "Are you sure you wish to remove this user?" Is there a way with php to handle this or would this be a job for javascript and if how how...?

Any thoughts....

Thanks...

You could try something like this:

<html>
<head>
	<title>Untitled</title>
</head>

<body>

<?
function Main()
{
	?>
	User Management:<br>
	<form action="ThisPage.php">
	<input type="submit" name="Submit" value="Add User">
	<input type="submit" name="Submit" value="Delete User">
	</form>
	<?
}

function Confirm()
{
	?>
	<form action="ThisPage.php">
	Are you sure you want to delete this user?
	<input type="submit" name="Submit" value="Yes">
	<input type="submit" name="Submit" value="No">
	</form>
	<?
}

function DeleteUser()
{
	//Delete the user info from the database
	echo "User was delete successfully.";
	echo "<a href='ThisPage.php'>Continue</a>";
}

function AddUser()
{
	//Stuff for adding a user
}

if ($_POST["Submit"] == "Delete User")
	{
		Confirm();
	}
elseif ($_POST["Submit"] == "Yes")
	{
		DeleteUser();
	}
elseif ($_POST["Submit"] == "Add User")
	{
		AddUser();
	}
else
	{
		Main();
	}
?>

</body>
</html>

So, the way this works is to use the value of the Submit button to control page flow. When you first call the page, $_POST["Submit"] = nothing, so the function Main() gets called. If you click on "Delete User" button, then the Confirm() function get's called, and so on... Also, your going to have to keep track of the UserID, probably with hidden form fields, and pass them into the fucntions, such as:

function Confirm($UserID)
// ...and...

if ($_POST["Submit"] == "Delete User")
	{
		Confirm($_POST["UserID"]);
	}

add this to your form tag:

onsubmit='return check(this);'

then higher up put

<script type='text/javascript'><!--
function check(form)
{
    var str;
    str = "Are you sure you want to delete";
    str += form.getElementByID('myinputfieldname').value;
    str += "?"
    return prompt(str);
}
//-->
</script>

its nicer than doing the whole PHP thing, but you have to have JS turned on for it to work.

Try this out
this script will return true if click OK otherwise return false

ans=confirm("are you sure you want to delete this item?");
return ans;
}
</script>

and in your code

<input type "checkbox" name="check[]" value=<? whatever the value is ?> onclick ="return deleteme()">
