php insert into mysql (wampserver) no errors but stills not working

Question

Hello I am trying to insert into tables located in a database using PHP7 and wampserver but it is not working even though the error code is 00000 and I debugged all the variables and they have the correct values, I am getting only the insert for table 'meal' working properly, here is the code I wrote, any tip could help, thanks.

<?php

function setConsultation($datas, $questionnaire, $nomeal, $type, $payement) 
{

    global $db;

    // Build sql syntax
    // for `Health` and `Questionnaire`
    $sql['health'] = '';

    foreach($questionnaire as $k=>$v) {
        $sql['health'] .=
           "INSERT INTO health(id_quest,qu_value)
            VALUES (:id_quest{$k},:qu_value{$k} );

            -- Questionnaire
            INSERT INTO questionnaire(id_health,id_cons)
            VALUES (LAST_INSERT_ID(),@cons_id);";
    }

    // Conditional meal
    $sql['meal'] = array('sql'   => '','value' => '');

    if (!$nomeal) {

        $sql['meal']['sql'] =
           'INSERT INTO meal(id_exp,quantity,price,ordered)
            VALUES(1,1,0,NOW());

            SET @meal_id = LAST_INSERT_ID();';

        $sql['meal']['value'] = '@meal_id';

    }else
        $sql['meal']['value'] = 'NULL';


    $sql['payement'] = $payement ?: '(SELECT MAX(id_price) FROM price)';
