Foreach Error

Napster

I am getting a Parse Error for this foreach loop.

foreach ($dlt as $key) {

  mysql_query("DELETE FROM owls WHERE reciever='$username' AND id='$key'") or die(mysql_error());

}

The error says:

Warning: Invalid argument supplied for foreach() in /home/roxiec/public_html/owls.php on line 15

Line 15 is the first line. I made sure that I spelled everything right and I can not find out why it is giving me this error.

Napster, the error is indicating an error with the $dlt array. Post the code above the foreach loop (specifically, the stuff where the $dlt array is being defined.) The part you posted looks fine as it is...

$dlt is not an array.

Napster

The code for the $dlt array comes from a form and this line which is

<input type=checkbox value=dlt[] value=$owls->id>

I have foreachs like this and they all worked.

Change:

to:

Also, you should get into the practice of quoting your attributes:
<input type=\"checkbox\" name=\"dlt[]\" value=\"$owls->id\">

LMAO, I am an idiot. Thank you. Ya, I usually go \", but only on strings.

You're welcome napster. Have a nice night, and be sure to mark the thread resolved... When you have some spare time, take a look at the W3Cs specifications and standards for HTML/XHTML and quoting attributes... You definitely want to get into the practice now, before strict enforcement is built into browsers.

Think about it like this: Say you have an input:

And the value of variable is "Hello World".

Well, without quotes like above, only "Hello" is passed in the form... but if you put your quotes on the attributes, then the entire variable is passed properly.

(Just my 2 cents)
