Hi, just a quick one, I want the user to have the option to edd extra fields when required, this is working by using the code below, but only once, I want a field to echo out every time they click the button.
How could and should this be done?
if (isset($_POST['extra'])) {
echo '
<!-- BOF Product Info -->
<div class="productInfo">
<div class="prodContain">
<span class="fontField bold">Product Description</span>
<input type="text" name="" value="" class="prodName" style="width: 280px" />
</div>
<div class="prodContain">
<span class="fontField bold">Serial Number</span>
<input type="text" name="" value="" class="prodName" style="width: 110px" />
</div>
<div class="prodContain">
<span class="fontField bold">Stock Number</span>
<input type="text" name="" value="" class="prodName" style="width: 110px" />
</div>
<div class="prodContain">
<span class="fontField bold">Quantity</span>
<input type="text" name="" value="" class="prodName" style="width: 50px;" />
</div>
<div class="prodContain">
<span class="fontField bold">Item Price</span>
<input type="text" name="" value="" class="prodName" style="width: 70px;" /></div>
</div>
<!-- EOF Product Info -->
';
}
?>
<div style="float: left;"><input type="submit" value="Extra Row" name="extra" id="subBtn" /></div>
So I basically need to know how to get the above code to echo everytime the button is clicked, not just once.
Here, this should help.

Hi, thanks for your message dude. Is there not a way to echo the fields depending on the URL using $_GET? So my user would enter how many products to be added and will then take them to fill out the details.
Not sure how I can multiply a variable though!?
Like this?
index.php?items=6
<?php
$items = isset($_GET['items']) && ((int)$_GET['items'] > 0) ? (int)$_GET['items'] : 1 ;
?>

Hey dude, that’s perfect, exactly the thing that I wanted, you got it spot on. Nice one.
Don’t quite fully understand what’s happening in the code below, I like to understand the workings of things 
It’s the && ((int)$_GET[‘items’] > 0) I’m not really getting.
$items = isset($_GET['items']) && ((int)$_GET['items'] > 0) ? (int)$_GET['items'] : 1 ;
Hi Anthony, just a quick question, now that I have dynamically generated fields depending on the URL, how can I enter these into the database in the mysql_query? I’m guessing listing each name of the field in the mysql_query isn’t an ideal solution to this.
Appreciate your help dude 
Hey no worries, sorry, I’m a bit rushed here.
<?php
if(true === is_array($_POST['lines'])){
foreach($_POST['lines'] as $num => $line){
#do stuff
$name = $line['name']
$desc = $line['description'];
}
}
Hey Anthony, apologies for resurrecting an old’ish post - only just had chance to take a look at this.Not sure your last post is meant for what my problem is - now that I have various fields depending on the URL, how can I enter these values into the database, for example sometimes there may only be two fields required to enter and other times there could be twenty.
I guess I could list each name of each field in the mysql_query but then I would be entering empty fields to the database if only a few fields are required.
Hope I’ve explained ok, tough to figure out!
