我有一个表单,数据通过ajax插入数据库.当输入字段有错误时,然后在每个字段的neath下显示错误.
但是当我选择图像并尝试将图像名称上传到数据库中时,没有任何内容,图像上传到上传路径,也没有将图像名称插入数据库.
控制器： –
在我的控制器中你可以看到我有一个名为result的数组,它有两个键状态和消息,默认状态为false.
在else部分中,循环正在运行,其中只有表单错误而不是任何类型的图像错误,这可能是因为没有显示图像的任何错误.
function infovalidation() {
$result = array('status' => false, 'message' => array());
$this->form_validation->set_error_delimiters('<div class="text-danger">','</div>');
if ($this->form_validation->run('company_registration')) {
$config['upload_path'] = 'assets/uploads/';
$config['allowed_types'] = 'gif|jpg|jpeg|png';
$this->load->library('upload',$config);
$this->upload->initialize($config);
if ($this->upload->do_upload('image'))
{
$data['upload_data'] = $this->upload->data('file_name');
$image_name = $data['upload_data'];
//$result['message'] = $this->upload->display_errors();
//$result['status'] = false;
}
else
{
$image_name = '';
}
$data = array(
'email' => $this->input->post('email'),
'first_name' => $this->input->post('firstname'),
'last_name' => $this->input->post('lastname'),
'pincode' => $this->input->post('pincode'),
'state' => $this->input->post('state'),
'landmark' => $this->input->post('landmark'),
'address' => $this->input->post('address'),
'state' => $this->input->post('state'),
'image' => $image_name,
'joined_date' => date('Y-m-d H:i:s')
);
$result['status'] = true;
$this->Perfect_mdl->c_insert($data);
}else {
foreach ($_POST as $key => $value) {
$result['message'][$key] = form_error($key);
}
}
echo json_encode($result);
}
阿贾克斯：
$("#form").submit(function(e){
e.preventDefault();
var me = $(this);
$.ajax({
url : me.attr('action'),
dataType : 'json',
type : 'POST',
data : me.serialize(),
success: function(resp) {
console.log(resp);
if (resp.status == true) {
$('#myModal').modal('show');
$(".form-group").removeClass('has-error').removeClass('has-success');
$(".text-danger").remove();
}else {
$('#msg').html('<div class="alert alert-danger"><h5>Please Check Your Details</h5></div>');
$.each(resp.message, function(key, value) {
var element = $("#"+key);
element.closest('.form-group')
.addClass(value.length > 0 ? 'has-error' : 'has-success')
.find('.text-danger').remove();
if(element.parent('.input-group').length) {
element.parent().after(value);
} else {
element.after(value);
}
// element.after(value);
});
}
}
});
});
如何将图像上传到数据库中,如果这不是正确的方法那么请建议正确的方法来做到这一点
解决方法:
对于使用ajax发送文件,请使用FormData而不是序列化
HTML5引入了FormData,允许开发人员动态构建表单对象,然后通过AJAX发送此表单对象.
视图
<form action="Your controller method name" method="post" id="form_img" enctype="multipart/form-data" accept-charset="utf-8">
<div>
username : <input type="text" name="name">
<span class="error name"></span>
</div>
<div>
password : <input type="text" name="password">
<span class="error password"></span>
</div>
<div>
file : <input type="file" name="image">
<span class="error image"></span>
</div>
<input type="submit" name="submit" value="submit">
</form>
Jquery电话
<script type="text/javascript" src="https://code.jquery.com/jquery-3.2.1.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$("#form_img").submit(function(e){
e.preventDefault();
var formData = new FormData($("#form_img")[0]);
$.ajax({
url : $("#form_img").attr('action'),
dataType : 'json',
type : 'POST',
data : formData,
contentType : false,
processData : false,
success: function(resp) {
console.log(resp);
$('.error').html('');
if(resp.status == false) {
$.each(resp.message,function(i,m){
$('.'+i).text(m);
});
}
}
});
});
});
</script>

function test_image() {

$this->form_validation->set_rules('name', 'name', 'required');
$this->form_validation->set_rules('password', 'password', 'required');

if ($this->form_validation->run() == TRUE) {
if($_FILES['image']['error'] != 0) {
$result['status'] = false;
$result['message'] = array("image"=>"Select image to upload");

$config['allowed_types'] = 'gif|jpg|jpeg|png';
$this->load->library('upload',$config);

$result['message'] = "Data inserted successfully.";
}
}else {
$result['status'] = false;
// $result['message'] = validation_errors();
$result['message'] = $this->form_validation->error_array();

echo json_encode($result);
