Is This PHP Within HTML?

Hello,

I found and used a script that works, but I don’t understand how it echos PHP within HTML. Please look at the following:

[php]echo "


<input type=‘hidden’ name=‘id[$i]’ value=’{$row[‘id’]}’ />
{$row[‘id’]}

<input class=‘scroller_field’ type=‘text’ size=‘20’ name=‘date[$i]’ value=’{$row[‘date’]}’ />
<input class=‘scroller_field’ type=‘text’ size=‘20’ name=‘location[$i]’ value=’{$row[‘location’]}’ />
<input class=‘scroller_field’ type=‘text’ size=‘42’ name=‘event[$i]’ value=’{$row[‘event’]}’ /> ";[/php]

‘echo’ is started with a double quote with single quotes used as HTML code. It’s as if the variables for name and value are being read by HTML, not PHP. Am I misunderstanding something here?

Not sure if I understand the problem. What does the HTML source look like when you run it?

If you are using a .html extension your server must be configured to parse PHP using that extension.

#3

PHP is echoing the HTML code with PHP variables in it. $i and $row are both PHP variables that should have double quotes around them, not single quotes?

#4

I’m still not sure what you are saying. The syntax of this code is fine.

Ok… I looked at the page’s source code. The use of [] is throwing me off. Where it has id[$i] it looks like id is a part of PHP, and I didn’t know you can write HTML as id[3] or something like that.

I still don’t understand {$row[‘id’]}. Why do you need the {} around it there and not in id[$i]? Is there a PHP page that explains this?

Using [] in a form is a way to send arrays. It would be similar to having a URL like ?var[]=1&var[]=2&var[]=3 which would give you an array of var = array(1, 2, 3)

Check this page for info about the curly brackets. See the section about variable parsing (simple vs complex)

Ok, thank you, Matt. I’ll read over that information.
