我可以上传＆amp;在数据库中插入图像。但我无法上传多个图像，我应该在下面的代码中更改，以便上传多个图像
我的form.php
<?php echo form_open_multipart('admin/addproduct'); ?>
<table border="0" cellspacing="0" cellpadding="0" style="width:60%;">
<tr>
<td style="vertical-align: top;width:50%;text-align: right;"> Product name </td>
<td style="vertical-align: top;width:50%;"><?php echo form_input($fpname) ?> </td>
</tr>
<tr>
<td style="vertical-align: top;width:50%;text-align: right;"> Price </td>
<td style="vertical-align: top;width:50%;"><?php echo form_input($fprice) ?> </td>
</tr>
<tr>
<td style="vertical-align: top;width:50%;text-align: right;"> Image 1: </td>
<td style="vertical-align: top;width:50%;"><?php echo form_upload("userfile"); ?></td>
</tr>
<tr>
<td style="vertical-align: top;width:50%;text-align: right;"> Image 2: </td>
<td style="vertical-align: top;width:50%;"><?php echo form_upload("img2"); ?> </td>
</tr>
<tr>
<td style="vertical-align: top;width:50%;text-align: right;">Image 3: </td>
<td style="vertical-align: top;width:50%;"><?php echo form_upload("img3"); ?> </td>
</tr>
<tr>
<td style="vertical-align: top;width:50%;text-align: right;"> Details </td>
<td style="vertical-align: top;width:50%;"><?php echo form_textarea($fdetails) ?> </td>
</tr>
<tr>
<td style="vertical-align: top;width:50%;text-align: center" colspan="2">
<input type="submit" value="Submit"/>
</td>
</tr>
</table>
<?php echo form_close(); ?>
Controller.php这样
function addproduct() {
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '1879800';
$config['max_width'] = '1024';
$config['max_height'] = '2768';
$config['encrypt_name'] = TRUE;
$this->load->library('upload', $config);
$this->load->library('form_validation');
$this->form_validation->set_error_delimiters('<li>', '</li>')->set_rules('pname', 'Product Name', 'trim|min_length[4]|required|max_length[112]');
$this->form_validation->set_error_delimiters('<li>', '</li>')->set_rules('details', 'Details', 'trim|min_length[4]|required|max_length[12]');
$this->form_validation->set_error_delimiters('<li>', '</li>')->set_rules('price', 'Price', 'trim|min_length[4]|required|max_length[112]|numeric');
if (!$this->form_validation->run()) {//--false
$data = $this->productmodel->productdetails();
$this->load->view('admin/home', $data);
}
if (!$this->upload->do_upload()) { // no file uploaded or failed upload
$error = array('error' => $this->upload->display_errors());
$data = $this->productmodel->productdetails();
print_r($error);
$this->load->view('admin/home', $data);
}
else
{
$data =$this->upload->data();
$this->productmodel->entry_insert_productdetails($data["file_name"]);
$data = $this->productmodel->productdetails();
$this->session->set_flashdata('msg', 'One record added successfully...');
redirect(base_url().'index.php/admin/index');
}
}
更新： 从表单生成的源代码
<form action="http://localhost/wclick/index.php/admin/addproduct" method="post" accept-charset="utf-8" enctype="multipart/form-data">
<table border="0" cellspacing="0" cellpadding="0" style="width:60%;">
<tr>
<td style="vertical-align: top;width:50%;text-align: right;"> Product name </td>
<td style="vertical-align: top;width:50%;"><input type="text" name="pname" value="" maxlength="190" size="20" /> </td>
</tr>
<tr>
<td style="vertical-align: top;width:50%;text-align: right;"> Price </td>
<td style="vertical-align: top;width:50%;"><input type="text" name="price" value="" maxlength="20" size="20" placeholder=" " id="txtsubject" /> </td>
</tr>
<tr>
<td style="vertical-align: top;width:50%;text-align: right;"> Image 1: </td>
<td style="vertical-align: top;width:50%;"><input type="file" name="userfile" value="" /></td>
</tr>
<tr>
<td style="vertical-align: top;width:50%;text-align: right;"> Image 2: </td>
<td style="vertical-align: top;width:50%;"><input type="file" name="img2" value="" /> </td>
</tr>
<tr>
<td style="vertical-align: top;width:50%;text-align: right;">Image 3: </td>
<td style="vertical-align: top;width:50%;"><input type="file" name="img3" value="" /> </td>
</tr>
<tr>
<td style="vertical-align: top;width:50%;text-align: right;"> Details </td>
<td style="vertical-align: top;width:50%;"><textarea name="details" cols="20" rows="4" ></textarea> </td>
</tr>
<tr>
<td style="vertical-align: top;width:50%;text-align: center" colspan="2">
<input type="submit" value="Submit"/>
</td>
</tr>
</table>
</form>

每次在do_upload之前调用以下函数
$this->upload->initialize($upload);
假设此数组中的所有文件
$ _ FILES [ 'userfile的'] [ '名称']
然后你的脚本看起来像
$this->load->library('upload');
for ($k = 0; $k < count($_FILES['userfile']['name']); $k++) {
$this->upload->initialize($upload); //must reinitialize to get rid of your bug ( i had it as well)
if (!$this->upload->do_upload('userfile',$k)) {
$this->load->view('upload/image_form', $data + array('error'=>$this->upload->display_errors()));
}
$udata[$k] = $this->upload->data(); //gradually build up upload->data()
}

如果您查看CI手册，则必须提供上传的字段名称。
$field_name = "some_field_name";
$this->upload->do_upload($field_name);
您需要为要更新的每个不同文件执行此操作，可能是循环播放。
