Shortcode wordpress with parameter

Question

I am creating a wordpress shortcode [ADD_POT ID='X'], which is able to get the ID value, in purpose to execute a function.

Unfortunately, there is an error within the third line of my code. Someone can give me a hand please ? Thank you.

function ADD_POT($atts) {
    $ID = shortcode_atts(array( 'ID' => TRUE), $atts) ;
    $pot_ID = $ID['ID'] ;
    include dirname(__FILE__) . '/../../../wp-config.php' ;
    include dirname(__FILE__) . '/../../../wp-content/plugins/Study-Tool/core/login.php' ;
    $pot_selection = "SELECT question_ID FROM questions WHERE pot_ID='$pot_ID'" ;
    $pot_result = mysqli_query ($connect,$pot_selection) ;
    foreach ($pot_result as $pot_ID) {
        $question_ID = $pot_ID['question_ID'] ;
        ADD_Q($question_ID) ;
    }
}

The real reason is because i need login for in purpose to use a complexe script, hide in ADD_Q — Adou Pro

Very bad idea to use relative link and include once again the wp-config.php. If you want to query and use sql query you only need to add global $wpdb; at the top of the function, and use plugins_url() (if your running this in a plugin) and get_stylesheet_uri() (for a theme) to include any file. — Benoti

Value in this line means default value your ID field have if user has not supplied a value.

$ID = shortcode_atts(array( 'ID' => TRUE), $atts) ;

You need to enclose values in '' in this line for example something like

$ID = shortcode_atts(array( 'ID' => ''), $atts) ;

if you want to have blank as default value. For any other value use the value but in quotes. If user gives a value in input then that value will be used instead of blanks or default value you give here.

Thank you for your answer Esha, but the real problem is, my function don't use the value given by the user in a post like [ADD_POT ID='X'], instead of the defaut value placed in the array :/

I solve the problem. It was because I used uppercase instead of lowercase in my wordpress balise.

[POT_ID **id**=4]

function ADD_POT($atts) {
    $ID = shortcode_atts(array( '**id**' => '1'), $atts);
    $pot_ID = $ID['**id**'];
}
