unset problem

[traq]

I will look at that more closely when I get home, but if you think something could be interfering then put the "deleting" code on a separate page, by itself, and see if it works then. If it does, than something is interfering within the main script.

After getting rid of the other php code, I still had the same problem.

keep troubleshooting...

// Deleting an Announcement)
if ( $_POST['deletechecker'] == 1 )
{
// check that the code is being triggered
echo $_POST['deletechecker'];

//    $dcount = array();
//  the above line IS COMMENTED OUT in your script, correct?

    $dcount = $_POST["dcount"];
//  Check that we're getting the correct $dcount value
    echo $dcount;

    $file = '../sidebar.xml';
    $xml = simplexml_load_file($file);

$i = 0;
foreach($xml as $kid){
// see what we're comparing $dcount to each time
    echo $kid->id;

    if($kid->id == $dcount){
//  see if script finds a match
echo $kid->id.' is equal to '.$dcount;
// make sure it's the right entry
echo $xml->myquotes[$i];

        unset($xml->myquotes[$i]); break;
    }
    $i ++;
}

$xml = $xml->asXML($file);  
}

I think I found the problem but do not understand.

when I echo $dcount, the reply is "Array" and becuase of this it is never equal to $kid->id.

The question is why is $dcount = Array instead of being an array?
I saw this before which lead me to comment out "$dcount = array();"

It IS an array. That's what you want. "echo" can only work with strings.
When you use "echo"+[non-string] the result will be a warning of sorts, like "array" or "resource" (for something like a mysql query).

(array(1)==array(1)) is true.
(array(1)==array(2)) is false.

There's no reason you can't match arrays.

But if you want to "echo" an array, you need to use another function. The common one is print_r($array);.

print_r($dcount)

worked fine.

So the problem seems to be on the line

if($kid->id == $dcount);

when I do an echo

$kid->id;

I get nothing back.

Or is the problem with the foreach line

foreach($xml as $kid){

I get no response from

echo $kid;

The problem has to be in the if statements. I just changed it to a not equal statement and echoed "hello" which was triggered for every record in my .xml file.

To echo on an array you had to do the print_r($array)...do we also need a trick for using them in if statements?

something like

if(in_array($kid->id, $dcount))

I love you guys. It works!

I thought that might be the problem - we added that a while back because you might have had multiple entries to delete. But then, I saw that the $dcount = array(); line was commented out, so I figured it was something else. But it's still an array because your html inputs are named "dcount[]". Duh.

I'm glad you got it figured out!

I wondered why I didn't need the

$dcount = array();

when I had to have it with the counter array. This is a good site to learn...thanks.
