【问题描述】:
我正在尝试使用 Ajax 在 CodeIgniter 中上传文件,但问题是文件正在上传到数据库中,但如果不加载页面就无法完成。每次我上传文件时,它都会成功上传,但会使用 JSON 代码导航到其控制器地址。我只想上传文件而不刷新页面。
查看文件
<?php echo form_open_multipart('maker/Checkout/docs', array('id'=>'upload_file')); ?>
<div class="form-group">
<label for="userfile">Upload existing CV</label>
<input class="form-control" type="file" name="userfile" id="userfile" size="20" />
</div>
<div class="form-group">
<button class="btn btn-info" type="submit">Upload</button>
</div>
<?php echo form_close() ?>
Ajax 代码
<script>
$(function() {
$('#upload_file').unbind('submit').bind('submit', function() {
e.preventDefault();
var form = $(this);
$.ajax({
url : form.attr('action'),
type: form.attr('method'),
data: form.serialize(),
secureuri :false,
fileElementId :'userfile',
dataType : 'json',
success : function (data, status)
{
if(data.status != 'error')
{
$('#files').html('<p>Reloading files...</p>');
}
alert(data.msg);
}
});
return false;
});
});
</script>
控制器
public function docs() {
$status = "";
$msg = "";
$file_element_name = 'userfile';
if ($status != "error")
{
$config['upload_path'] = dirname($_SERVER["SCRIPT_FILENAME"])."/assets/img/posts";
$config['upload_url'] = base_url()."/assets/img/posts";
$config['allowed_types'] = 'gif|jpg|png|jpeg|pdf|doc|docx|docs|txt|xml';
$config['max_height'] = 102048;
$config['max_width'] = 102048;
$config['max_size'] = 1024 * 8;
$config['encrypt_name'] = TRUE;
$this->load->library('upload', $config);
if (!$this->upload->do_upload($file_element_name))
{
$status = 'error';
$msg = $this->upload->display_errors('', '');
}
else
{
$data = $this->upload->data();
$file_id = $this->Checkout_model->newcheckout($data['file_name']);
if($file_id)
{
$status = "success";
$msg = "File successfully uploaded";
}
else
{
unlink($data['full_path']);
$status = "error";
$msg = "Something went wrong when saving the file, please try again.";
}
}
@unlink($_FILES[$file_element_name]);
}
echo json_encode(array('status' => $status, 'msg' => $msg));
}
我只想上传文件而不刷新页面。目前,它正在上传文件,但上传后导航到控制器地址。
