Invalid argument supplied for foreach()

cruhmm

how do I block this error message?

My foreach() statement works just fine but I keep getting this error message on every pass and I really don't know why.

Please help me out. I just just don't want the error message to mess up my page. Would using @ block it? I could't get it to work. Thanks...

Your "foreach()" isnt working because the argument supplyed is not a array(probably). Foreach works only on arrays.
Post the code.

//here is how you should always code a foreach loop in php
if(is_array($var)) {
    foreach($var as $whatever) {
        //processing code here
    } //end foreach
} //end if

this way if your variable is not an array for any reason it will be kept away from the foreach loop and prevent the ugly php message you are getting. For error trapping you can use the else condition on the if statement.

foreach($this->prop_ids as $key){ SQL Query(get data using $key[0]) }

$prop_ids =
Array
(
[0] => Array
(
[0] => 1
)
[1] => Array
(
[0] => 2
)
[2] => Array
(
[0] => 4
)
)

Then I just call $key[0] in my SQL query.

Using "$key => $value" $key returns one empty loop and $value has no value.

I am passing it an array it seems...any other suggestions?

Note: I also get warnings when I do a mysql_fetch_row. But those I can simply @ out...hrmm...
