In English, please? This is an English-speaking community, after all.

Thank you.

 

In any case an "undefined index" means that you're trying to reference an array key, which has not been set yet. The proper way to fix these messages, is by checking if the key isset () before trying to use its value.

 

Like this:

// Test data
$test = array ("Exists" => true);

// Gives an undefined index.
echo $test['not'];

// Test first.
if (isset ($test['not')) {
    // No message, and no warning.
    echo "You won't see this.";
} else {
    echo "Index 'not' is not set.";
}

I'm afraid I don't understand. What are you wondering about?

 

PS: When asking for help on your PHP code it's also recommended to post the part of the code that you're having trouble with, using the

tags around it.
