Add extra line in two places

Local_Hero

I got help writing php to add an extra row of input fields when the user clicks a button:
<?php
$rowsx=1;
if(isset($POST["rowsx"])){
$rowsx=$POST["rowsx"];
}
for($e=1;$e<=$rowsx;$e++){
?>
<td><tr>
<div align="center">Quantity -
<input name="product_options_amount<?php echo $e ?>" type="text" id="product_options_amount" value="<?php echo($POST["product_options_amount".$e]);?>" style="text-align:center" size="3" />
</div></td>
<td>
<div align="center">Color -
<select name="product_options_color<?php echo $e ?>" id="product_options_color" >
<option value="White"<?php if(isset($POST["product_options_color".$e])){if($POST["product_options_color".$e]==="white"){echo " selected";}}?>>White</option>
<option value="Black"<?php if(isset($POST["product_options_color".$e])){if($POST["product_options_color".$e]==="black"){echo " selected";}}?>>
Black
<option value="Red"<?php if(isset($POST["product_options_color".$e])){if($_POST["product_options_color".$e]==="2"){echo " selected";}}?>>Red</option>
</div></td>
</tr>
<?php
}
?>

It works great, but I need one more thing. When the user adds another line, I need it to create a textbox for each line added. This textbox will be in another form. I think you'd put the php in the second form and use the variable $e, but I'm not sure how. Thanks.

so, did you learn anything when you got 'help' making this script? obviously not or you wouldn't be asking for more 'help'.

this is the whole reason i wont write code for people. it does no one any favours.

besides all that, this whole thing could be done more efficiently using a client-side technoligy such as javascript.

if you still want 'help', please explain what part you are stuck on.

I'm sorry, you must be in the wrong forum. This is the general help forum where people can gain help from experts, not be criticized for what they know. Furthermore, as someone new to PHP, I did learn something. You may have missed the part where I said, "I think you'd put the php in the second form and use the variable $e." $e is the number associated with how many lines there are. In the second form I would imagine it would be something like the first php.

<?php
something{
?>
textbox
<?php
}
?>

I would not be asking this if I hadn't tried it myself. Yes, I did learn something from the help. But I could not get it to work. I don't understand what it needs to know to create the textbox from the button in the first form:
<input type="hidden" name="rowsx" value="<?php echo $rowsx+1; ?>" />
<input name="submit" type="submit" value="Add another row" />

As for your javascript idea, this is for a simple shipping cart. I would rather not lose 18% of my business because the only way to make it work is with JS. The PHP is fine.

Again I ask, if anyone can offer some general help to someone who does not completly understand php, I would appreciate it.:bemused:

the way i see it, if you understand how the code you have works, then you would understand how to develope the solution your looking for.

I must say, that reply was brilliant! Not only did you ask me where exactly I was having problems with the code, but I even wrote “I don't understand what it needs to know to create the textbox from the button in the first form.” From this statement, Thorpe (The Aussie Mastermind as he is called in Sydney) concluded that I do understand how to implement the php needed. I guess I was just trying to waste everyone’s time (including mine) by asking questions I already know? Bravo Thorpe, you are truly a genius among men.
