我正在试图在codeigniter中将数据从表单传递给控制器​​...但是当我想打印一个包含结果的表时...我在表的每一行都得到null。这是我的代码:

表格

<form class="col s12" id="update_form" name="update_form" method="post" >
      <div class="row">
        <div class="input-field col s6">
          <input id="update_name" type="text" name="name" class="validate">
          <label for="first_name">Nombre</label>
        </div>
        <div class="input-field col s6">
          <input id="update_last_name" name="lastname" type="text" class="validate">
          <label for="last_name">Apellido</label>
        </div>
      </div>
      <div class="row">
        <div class="input-field col s6">
          <input id="update_side" type="text" name="side" class="validate">
          <label for="partido">Partido</label>
        </div>
        <div class="input-field col s6">
          <input id="update_charge" type="text" name="charge" class="validate">
          <label for="cargo">Cargo</label>
        </div>
      </div>
        <div class="row">
            <div class="input-field col s6">
               <div class="file-field input-field no-margin-top">
                  <div class="btn light-blue darken-4">
                    <span>Animación</span>
                    <input type="file">
                  </div>
                  <div class="file-path-wrapper">
                    <input class="file-path validate" name="animation" type="text">
                  </div>
                </div>
            </div>

            <div class="input-field col s6">
            <select id="update_section" name="section" autocomplete="off">
              <option value="" disabled selected>Seleccione una opción</option>
              <option value="1">Presidencia</option>
              <option value="2">Senadores</option>
              <option value="3">Diputados</option>
            </select>
            <label>Sección</label>
          </div>
        </div>
        <input type="hidden" name="update_politic_hide" id="update_politic_hdn" value="">
    </form>

Jquery的

$("#update_politic_btn").click(function(event) {
    /* Act on the event */

    var chango = $("#update_form").serialize();
    alert(chango);
    $.post(baseurl + 'admin/update_politic', {
            data: chango
        },
        function(data) {
            console.log(data);
            list_politic();
        });
    event.preventDefault();
});

控制器

public function update_politic(){

  if ($this->input->is_ajax_request()) {


  $params["name"] = $this->input->post("name");
  $params["lastname"] = $this->input->post("lastname");
  $params["side"] = $this->input->post("side");
  $params["charge"] = $this->input->post("charge");
  $params["animation"] = $this->input->post("animation");
  $params["section"] = $this->input->post("section");
  $params["id"] = $this->input->post("update_politic_hide");

  if ($params["section"]=="Presidencia") {
      $params["section"]=1;
  }

  if ($params["section"]=="Senadores") {
      $params["section"]=2;
  }

  if ($params["section"]=="Diputados") {
      $params["section"]=3;
  }

  $this->load->model("politic");
  $this->politic->update($params);
}
}

MODEL

public function update($param){

  $id = $param["id"];
    $values = array(

                    "POLITIC_NAME" => $param["name"],
                    "POLITIC_LASTNAME" => $param["lastname"],
                    "POLITIC_SIDE" => $param["side"],
                    "POLITIC_CHARGE" => $param["charge"],
                    //"animation" => $param["animation"],
                    "SECTION_ID" => $param["section"],
                    );


    $this->db->update("politics",$values);
  $this->db->where("POLITIC_ID",$id);
}

HELP !!!我不知道为什么一旦我想要打印结果我就得到空值!!

你的情况首先应该是,

public function update($param){
   $id = $param["id"];
   $values = array(
      "POLITIC_NAME" => $param["name"],
      "POLITIC_LASTNAME" => $param["lastname"],
      "POLITIC_SIDE" => $param["side"],
      "POLITIC_CHARGE" => $param["charge"],
       //"animation" => $param["animation"],
       "SECTION_ID" => $param["section"],
   );
   $this->db->where("POLITIC_ID",$id);
   $this->db->update("politics",$values);
}  

如果代码无效,请告诉我们您的list_politic();代码。

如果您使用serialize(),我认为您的传递数据方式不正确,然后直接在$.post中使用,

$.post(baseurl + 'admin/update_politic',chango,function(data) {
   console.log(data);
   list_politic();
});
