So, i've got this page:



And i need the contents of the ingredients boxes to be added to a cookie in the format:

ingredient:quantity

And i also need ajax to remove the cookie and display the values of the cookies in the table.

So far, i've worked out that:

<?php print_r($_COOKIE); ?>

Will display all the cookies on the same domain as the script.

So that can be used for loading all the cookies, then using PHP to explode out the ':'s.

But i've never used ajax before, so i need some help. My attempt failed - nothing happened when i clicked the 'Add Ingredient' button.

Can anyone with Ajax experience help me?

Thanks

If you are using cookies to pass the information to PHP, it isn't Ajax

In this case I don't even think you'll be needing Ajax. Just some Javascript will be enough.

I guess this is for a MyBB plugin? And everything is in a form?

If this is for MyBB you can use the Prototype JS which is already include in the core to help you a bit along.
I scribbled some code together for an example: http://jsbin.com/ujoso5/edit (click preview to see it in action)
Fill in an ingredient and the quantity and click the Add button. This will insert a new row above the current row with the values you just entered and the add button will be replaced by a remove button. Because the input fields are named "ingredient[]" and "quantity[]" these fields will show up as an array in the $_POST or $mybb->input variables. You can loop through them to when handling the form submission like this:

$ingredient_count = count($mybb->input['ingredient']);
for($i=0; $i < $ingredient_count; $i++)
{
    // ignore empty ingredients
    if(empty($mybb->input['ingredient'][$i])) continue;

    $ingredient = $mybb->input['ingredient'][$i];
    $quantity = $mybb->input['quantity'][$i];
    // do something with those variables
}

I hope this helps you.

Now this is nifty, and I will be looking at it in more detail - but - in the demo - the text we enter does not stay visible....

Is that because its the demo?

Its JUST what I have been looking for to use in threads submissions

There is no save option in the demo, no. This is only to demonstrate the Javascript because that is what, I think, the TS needed in this case.

Its not for a MyBB plugin, but that code is perfect

Thank you sooo much

However, there is a problem - i need to echo the individual ingredients onto a blank page, but i can't get them to be seperate.

This is the code i'm using:

$ingredient_count = count($_POST['ingredient']);

for($i=0; $i < $ingredient_count; $i++) {
	// ignore empty ingredients
	if(empty($_POST['ingredient'][$i])) continue;

	$ingredient = $_POST['ingredient'][$i].":".$_POST['quantity'][$i];
    
}

echo $ingredient;

However, it only displays the last ingredient that was in the textboxes.

Do a foreach maybe?

You overwrite the variable each time. Let me guess: you only see the last one?

Try this:

$ingredient_count = count($_POST['ingredient']);
$ingredients = "";

for($i=0; $i < $ingredient_count; $i++) {
    // ignore empty ingredients
    if(empty($_POST['ingredient'][$i])) continue;

    $ingredients .= $_POST['ingredient'][$i].":".$_POST['quantity'][$i] ."<br/>";
    
}

echo $ingredients; 

I already solved this on msn, sorry for not letting you know

Its always handy to have the information in the thread though - I think a lot of people are interested in this.
