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!!
答案 0 :(得分:0)
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();
});
