我正在使用Codeigniter和Mysql。我试图向mysql表发送多个复选框下拉值。但只有一个价值有价值。它是去数据库的最后一个值。我也尝试过其他一些方法。但最后我在这里。提前谢谢。
以下是视图。
<div class="form-group">
<select class="form-control" data-toggle="dropdown"></select>
<ul class="dropdown-menu">
<li>
<a href="#" name="sub_cat_id" id="sub_cat_id" class="small" data-value="option1" tabIndex="-1">
<input name="sub_cat_id" id="sub_cat_id" type="checkbox"/ ><?php echo $this->lang->line('select_sub_cat_message')?>
</a>
</li>
</div>
<script>
$(document).ready(function(){
$('#item-form').validate({
rules:{
name:{
required: true,
minlength: 4,
remote: {
url: '<?php echo site_url("items/exists");?>',
type: "GET",
data: {
name: function () {
return $('#name').val();
},
sub_cat_id: function() {
return $('#sub_cat_id').val();
}
}
}
},
unit_price: {
number: true
}
},
messages:{
name:{
required: "Please fill item Name.",
minlength: "The length of item Name must be greater than 4",
remote: "Item Name is already existed in the system"
},
unit_price: {
number: "Only number is allowed."
}
}
});
$('#cat_id').change(function(){
var catId = $(this).val();
$.ajax({
url: '<?php echo site_url('items/get_sub_cats');?>/'+catId,
method: 'GET',
dataType: 'JSON',
success:function(data){
$('#sub_cat_id').html("");
$.each(data, function(i, obj){
// $('#sub_cat_id').append('<option value="'+ obj.id +'">' + obj.name + '</option>');
$('#sub_cat_id').append('<input name="sub_cat_id" type="checkbox" value="'+ obj.id +'"/> ' + obj.name + '');
});
$('#name').val($('#name').val() + " ").blur();
}
});
});
$('#sub_cat_id').on('change', function(){
$('#name').val($('#name').val() + " ").blur();
});
$(function () { $("[data-toggle='tooltip']").tooltip(); });
});
</script>
这是控制器功能
function add()
{
if(!$this->session->userdata('is_shop_admin')) {
$this->check_access('add');
}
$action = "save";
unset($_POST['save']);
if (htmlentities($this->input->post('gallery'))) {
$action = "gallery";
unset($_POST['gallery']);
}
if ($this->input->server('REQUEST_METHOD')=='POST') {
$item_data = array();
foreach ( $this->input->post() as $key=>$value) {
$item_data[$key] = htmlentities($value);
}
$item_data['shop_id'] = $this->get_current_shop()->id;
$item_data['is_published'] = 1;
//unset($item_data['cat_id']);
if ($this->item->save($item_data)) {
$this->session->set_flashdata('success','Item is successfully added.');
} else {
$this->session->set_flashdata('error','Database error occured.Please contact your system administrator.');
}
if ($action == "gallery") {
redirect(site_url('items/gallery/'.$item_data['id']));
} else {
redirect(site_url('items'));
}
}
$cat_count = $this->category->count_all($this->get_current_shop()->id);
$sub_cat_count = $this->sub_category->count_all($this->get_current_shop()->id);
if($cat_count <= 0 && $sub_cat_count <= 0) {
$this->session->set_flashdata('error','Oops! Please create the category and sub category first before you create items.');
redirect(site_url('items'));
} else {
if($cat_count <= 0) {
$this->session->set_flashdata('error','Oops! Please create the category first before you create items.');
redirect(site_url('items'));
} else if ($sub_cat_count <= 0) {
$this->session->set_flashdata('error','Oops! Please create the sub category first before you create items.');
redirect(site_url('items'));
}
}
$content['content'] = $this->load->view('items/add',array(),true);
$this->load_template($content);
}
这是模型函数
function save(&$data, $id = false)
{
if (!$id && !$this->exists(array('id' => $id, 'shop_id' => $data['shop_id']))) {
if ($this->db->insert($this->table_name, $data)) {
$data['id'] = $this->db->insert_id();
return true;
}
} else {
$this->db->where('id', $id);
return $this->db->update($this->table_name, $data);
}
return false;
}
答案 0 :(得分：0)
修改1 忘了查看显而易见的，在视图中查看
<a href="#" name="sub_cat_id"
id="sub_cat_id"
class="small" data-value="option1"
tabIndex="-1">
<input name="sub_cat_id" id="sub_cat_id" type="checkbox"/ >
<?php echo $this->lang->line('select_sub_cat_message')?>
</a>
U具有<a>和<input>标记的相同名称。
<强> ____________________________________________________________________
您要将此信息发送到服务器
<input name="sub_cat_id" id="sub_cat_id" type="checkbox"/ >
<?php echo $this->lang->line('select_sub_cat_message')?>
</a>
问题在于name="sub_cat_id"它是一个字符串，你需要一个数组，解决此问题的一种方法是将名称重命名为name="sub_cat_id[]"，并且要在控制器功能中检索它，你可以使用
function functionThatProcessesTheForm(){
$subCatIds = $this->input->post('sub_cat_id');
/**
subCatIds its an array, the value of each element will be
the "value" the input had, if it wasn't selected, it will not be
contained in the array
**/
}
重要
如果输入value ="theidvalue"，请设置值，如果您的ID不会到达控制器，如果设置了值，您将找到[1,1,1,1,1,1]之类的数组，你的数组将是[id1,id2,id3,...,idn]
希望我的回答可以帮到你。
