avaliar erro de conexão mysql

Recommended Posts

a muito que utilizo uma classe de conexão mysql e ela me tem sido muito util e eficiente para o que necessito.

http://thephpeffect.com/a-basic-database-connection-manager/

entretanto, hoje estou precisando considerar erros na conexão, e esta classe não os strata.

Alguém poderia avaliar o código abaixo, e me orientar como adicionar o retorno de algum erro?

Grato

 class DatabaseManager {
        private static $_instances = array(); 
        public static function getInstance($instance_name, $connection_info = array()) {
            if($connection_info) {
                list($db_host, $db_user, $db_pass, $db_name) = $connection_info;
                self::$_instances[$instance_name] = new MySQLi($db_host, $db_user, $db_pass, $db_name);
            }
            return self::$_instances[$instance_name];
        }
    }
     function db($instance_name='default', $connection_info = array()){
        return DatabaseManager::getInstance($instance_name, $connection_info);
    }

      Olá a todos(as), boa tarde!
       
      Tenho uma Query e um pequeno código em PHP para mostrar os resultados em uma tabela, mas estão repetindo os resultados da Query. Gostaria de uma solução, ou uma gambiarra para isso.
      Query
      SELECT DISTINCT b.ID AS "ID", b.Character AS "Personagem", b.Money AS "DinMao", b.BankMoney AS "DinBanco", b.Savings2 AS "DinPoupa", c.houseOwner AS "IDono", SUM(c.houseMoney) AS "DinCasa" FROM characters b INNER JOIN houses c ON (b.ID = c.houseOwner) ORDER BY ((b.Money+b.BankMoney+b.Savings2+c.houseMoney)) DESC LIMIT 0, 1000 PHP
      if(mysqli_num_rows($q) > 0) { while($r = $q->fetch_assoc()) { //Código da Tabela } }  
      Observação:
      Quando eu removo a seguinte parte da minha Query que é: SUM(c.houseMoney) AS "DinCasa" e deixo assim: c.houseMoney AS "DinCasa"
      Os dados da minha tabela repetem, não sei o motivo e/ou a circunstância disso. Mas peço a ajuda de vocês para solucionar. Vale ressaltar que (ID e houseOwner) tem os mesmos valores, só o valor da casa que recebe o valor do ID, e ele pode ter quantas casa ele quiser, e se ele tiver cinco casas, mostrará o resultado cinco resultados na minha tabela, como posso resolver isso?
       
       
      Meu muito obrigado desde já.

      Olá,
      tenho uma aplicação PHP com algumas funções que não estão funcionando na hospedagem.
      Esta aplicação utiliza apenas conexão com banco de dados -> mysql_connect, mysql_select_db, entre outras de MYSQL.
      Alguma ideia de qual extensão, dentre as existentes na imagem anexa deveria(m) estar ativada(s)?
       
      Um abraço!

      Estou sofrendo a um tempo com consumo alto de CPU em meu servidor na maioria dos casos em virtude do MYSQL, trabalho com PHP e APACHE e MYSQL. Realizei inúmeras tentativas para acabar com o alto consumo porém todas fracassadas. O evento costuma ocorrer sempre nos mesmos horários, parte da manhã por volta de 9:30/11:00 e parte da tarde entre 14:00/16:00. Meu servidor possui hardware suficiente para suportar, porem acredito que esteja mal configurado. Estou encaminhando alguns processos que observo estar executando em excesso obtidos através do ps aux.
      dovecot/pop3-login
      dovecot/imap-login
      dovecot/lmtp -L
      php-fpm: pool app (o que mais aparece)
      Ps: utilizo um servidor CENTOS 7

      Boa tarde pessoal,
       
      acredito que estou com o problema e a solução no post só que nao sei exatamente aonde alterar o codigo.
      Um site de servidor de games de um cliente esta com um problema na aba forum. é um  forum simples para questoes relacionadas ao game.
      Irei anexar alguns prints para facilitar o entendimento e o codigo.
       
      Resumindo: O problema é que o forum tem algumas boards (News, Wars, Quests, Pictures e Bug reports), suponhamos que dessas boards Pictures tem 4 posts e Quests 1 post. Se o primeito post do forum for em Pictures, quando eu tentar abrir o post de Quests ele ira me redirecionar para Pictures, e dentro de pictures terá todos os posts de todas as boards. Se eu tentar excluir algum topico de qualquer board, todos os topicos são excluidos.
       
      Acredito que o problema esteja no criação do ID do post na database, todos estão sendo gerados como ID 0. Imagino que a função new_post não está trabalhando corretamente.
       
      se alguem puder me ajudar eu fico muito agradecido mesmo!! to quebrando a cabeça aqui a um tempo, só falta isso pra terminar.
       
       
      PRINTS E EXPLICAÇÃO:
       
      print de todos as boards
       
      print da board war (observe que existe apenas um post nessa board)
       
      print apos selecionar post da board war (repare que fui redirecionado para a board Report Bug que foi a que eu criei o primeiro post do forum como expliquei acima no resumo)
       
      print do banco de dados (todos os IDs são 0)

      Eu tô fazendo um site pra uma imobiliária e nele eu possui filtros que não são obrigatórios e nem possuem submit, ex: quantidade de quartos, quantidade de vagas, localização e assim por diante, algo em torno de 15 filtros o usuário pode escolher os filtros que deseja e assim o site realizar uma busca, como não tenho submit tô usando ajax e javascript pra conseguir recuperar os valores, o meu problema está em executar um query com esses valores, eu tô com um form de teste com dois campos só, porém ele não ta executando redondinho do jeito que  preciso, tenho um input e um select se eu selecionar um dos dois ele executa a query mas mostra que a outra não está definida, se eu preencho as duas ele não executa a query, se alguém puder me dar um help em como fazer isso agradeceria muito, tô enrolada nisso faz um tempinho já
      <body> <form method="POST" id="form-pesquisa" action=""> <input type="text" id="pesquisa" style="width: 35%; height: 40px; text-align: center; font-size: 25px;"/> <select name="idade" id="select_idade"> <option value="19" selected>19</option> <option value="18">18</option> </select> </form> <div class="resultado" style="border: 1px solid #222; width: 35%; margin-top: 30px; height: 30px;"> </div> </body> $(function(){ $("#select_idade").change(function(){ var select_idade = $(this).val(); if(select_idade != ''){ var select = { idade : select_idade } $.post('busca_banco.php', select, function(retorna){ $(".resultado").html(retorna); }); }else{ $(".resultado").html(''); } }); //Pesquisar sem refresh na página $("#pesquisa").keyup(function(){ var pesquisa = $(this).val(); //Verifica se há algo digitado if(pesquisa != ''){ var dados = { palavra : pesquisa } $.post('busca_banco.php', dados, function(retorna){ //Mostra dentro da div os resultados obtidos $(".resultado").html(retorna); }); }else{ $(".resultado").html(''); } }); }); $idade = $_POST['idade']; $busca = $_POST['palavra']; $busca_select = "SELECT * FROM teste WHERE TRUE AND IF('$idade' != 0, TRUE) AND IF('$busca' !=0, TRUE)"; $result_busca = mysqli_query($cnn, $busca_select); if(mysqli_num_rows($result_busca)<=0){ echo '<div style = "width:80%; overflow:auto; border-bottom:1px solid #333"> Não existe resultado </div> '; }else{ while ($rows = mysqli_fetch_assoc($result_busca)){ echo '<div style = "width:35%; overflow:auto; border-bottom:1px solid #333"> '.$rows['idade'].' - '.$rows['palavra'].' <br> </div> '; } }
