我需要有关使用 CodeIgniter 上传图片代码的帮助。请参考我下面的代码
我确实尝试过 File Upload 类，但我无法在已创建的代码上使用它来添加新产品。
这是我的表格
<form action="<?php echo base_url().'index.php/admin/Welcome/add_new_product'; ?>" method="POST">
<section class="content">
<div class="row">
<div class="col-md-12">
<div class="box box-info">
<div class="box-header">
<h3 class="box-title">Product description
<small></small>
</h3>
<h1><input type="textarea" name="pd_title" placeholder="Enter Title Here" style="width:100%;"></h1>
</div>
<!-- /.box-header -->
<div class="box-body pad">
<textarea id="editor1" name="pd_short_desc" rows="10" cols="80">
This is my textarea to be replaced with CKEditor.
</textarea>
</div>
<div class="box-body pad">
<label for="Image">Upload Image</label>
<input type="file" name="pd_img" value="" style="padding:10px;">
</div>
<div class="box-body pad">
<h3 class="box-title">Description to right of Image</h3>
<textarea id="editor2" name="pd_info_right" rows="10" cols="80">
This is my textarea to be replaced with CKEditor.
</textarea>
</div>
<div class="box-body pad">
<h3>Product Complete Description</h3>
<textarea id="editor3" name="pd_desc" rows="10" cols="80">
This is my textarea to be replaced with CKEditor.
</textarea>
</div>
<input type="submit" name="submit" class="btn btn-info btn-raised ink-reaction">
</form>
这是我的控制器
public function add_new_product()
{
$p = $this->model_one->add_new_product();
redirect('admin/Welcome/view_products');
}
此模型应在 mysqli db 表中插入数据
public function add_new_product()
{
$pd_title = $_POST['pd_title'];
$pd_short_desc = $_POST['pd_short_desc'];
$pd_image = $_POST['pd_image'];
$pd_info_right = $_POST['pd_info_right'];
$pd_desc = $_POST['pd_desc'];
$sql = $this->db->query("INSERT INTO products (pd_title, pd_short_desc, pd_image, pd_info_right, pd_desc)
VALUES('$pd_title','$pd_short_desc', '$pd_image','$pd_info_right','$pd_desc')");
return "yes";
}
提交此表单时，Image 需要上传到uploads 文件夹中，并插入到mysqli db 中的products 表中。
做一些改变
看法
enctype="multipart/form-data"在<form>标签中添加
<form action="<?php echo base_url().'index.php/admin/Welcome/add_new_product'; ?>" method="POST" enctype="multipart/form-data">
控制器
获取POST控制器中的值
public function add_new_product()
{
$data = array('pd_title' => $_POST['pd_title'], 'pd_short_desc' => $_POST['pd_short_desc'], 'pd_info_right' => $_POST['pd_info_right'], 'pd_desc' => $_POST['pd_desc']);
$config['upload_path'] = FCPATH.'uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = 100;
$config['max_width'] = 1024;
$config['max_height'] = 768;
if(isset($_FILES['pd_img']['name'])){
$this->load->library('upload', $config);
if(!$this->upload->do_upload('pd_img')){
print_r($this->upload->display_errors());
}else{
$data['pd_image'] = $this->upload->data('file_name');
}
}
$this->model_one->add_new_product($data);
redirect('admin/Welcome/view_products');
}
模型
public function add_new_product($data)
{
return $this->db->insert('products', $data);
}
