[英]Conflict when uploading images with multiple file field in codeigniter
Codeigniter: File successfully upload when setting only one field(individual). Codeigniter:仅设置一个字段(单个)时文件成功上传。 But when setting both field second file is also uploaded to first's location. 但是同时设置两个字段时,第二个文件也将上传到第一个文件的位置。 How to solve this conflict. 如何解决这个冲突。 Is there any tutorial for multiple upload field???? 是否有关于多个上传字段的教程????
My code is given below: 我的代码如下:
<input type="file" name="filePrdimage" id="filePrdimage" size="20"/>
<input type="file" name="filePrdlogo" id="filePrdlogo" size="20"/>
. 。 // Image uploading codes //图片上传代码
$config['upload_path'] = 'assets/images/b2bproduct';
$config['allowed_types'] = 'gif|jpg|jpeg|png';
$config['max_size'] = '1000';
$config['max_width'] = '2024';
$config['max_height'] = '1768';
$config['overwrite'] = TRUE;
$config['remove_spaces'] = TRUE;
if (isset($_FILES['filePrdimage']['name'])) {
$config['file_name'] = substr(md5(time()), 0, 28) . $_FILES['filePrdimage']['name'];
}
$this->load->library('upload', $config);
if (!$this->upload->do_upload('filePrdimage')) {
//no file uploaded or failed upload
$error = array('error' => $this->upload->display_errors());
} else {
$dat = array('upload_data' => $this->upload->data());
$this->resize($dat['upload_data']['full_path'], 'assets/images/b2bproduct/thump/'.$dat['upload_data']['file_name'],180,400);
}
if (empty($dat['upload_data']['file_name'])) {
$prdimage = $this->input->post('hdPrdimage');
}
else {
$prdimage = $dat['upload_data']['file_name'];
}
// End Image uploading Codes
// Logo uploading codes
$config['upload_path'] = 'assets/images/b2blogo';
$config['allowed_types'] = 'gif|jpg|jpeg|png';

$this->load->library('upload', $config);
if (!$this->upload->do_upload('filePrdlogo')) {

$this->resize($dat['upload_data']['full_path'], 'assets/images/b2blogo/'.$dat['upload_data']['file_name'],135,300);
}
if (empty($dat['upload_data']['file_name'])) {
$prdlogo= $this->input->post('hdPrdlogo'); ;
}
else {
$prdlogo=$dat['upload_data']['file_name'];
}
// End Logo uploading Codes
public function resize($source,$destination,$width,$height) {
$config['image_library'] = 'gd2';
$config['source_image'] = $source;
$config['create_thumb'] = FALSE;
$config['maintain_ratio'] = TRUE;

I think you should do only one function to upload images that has data array as parameter where you may include the path and other variables. 我认为您应该只执行一项功能,以上传具有数据数组作为参数的图像,其中可以包含路径和其他变量。
public function upload(array $data)
{
$config['upload_path'] = isset($data['upload_path']) ? $data['upload_path'] : 'default/path';
...
$this->load->library('upload', $config);
if (!$this->upload->do_upload($data['field')) {
//no file uploaded or failed upload
$error = array('error' => $this->upload->display_errors());
} else {
$dat = array('upload_data' => $this->upload->data());
$this->resize($dat['upload_data']['full_path'], $data['upload_path'].$dat['upload_data']['file_name'],135,300);
}
...
}
When you submit the form, check for all input fields with the $_FILES global and call the upload function when necessary with the upload array $data set for each of them. 提交表单时,请检查所有带有$ _FILES全局变量的输入字段,并在必要时调用上载函数,并为每个输入字段设置上载数组$ data。
