这是控制器，我没有错误
for (Iterator<String> it1 = proptypeconf.columnKeySet().iterator(); it1.hasNext();) {
String type = it1.next();
System.out.println(type);
for (Iterator<Map.Entry<String, Double>> it2 = proptypeconf.column(type).entrySet().iterator(); it2.hasNext();){
Map.Entry<String, Double> e = it2.next();
if (e.getValue() < conflist.get(index-1)) {
it2.remove();
}
}
}
查看
public function admin_page(){
if($this->input->post('add_product')){
if(empty($_FILES['userfile']['name'])){
$data = array(
'category' => $this->input->post('category') ,
'product_name' => $this->input->post('name') ,
'description' => $this->input->post('description'),
'image' => 'no_image.jpg'
);
} else{
$config['upload_path'] = './public/images/';
$config['allowed_types'] = 'gif|jpg|png|jpeg|JPG';
$config['max_size'] = '1000';
$this->load->library('upload', $config);
$this->upload->do_upload('userfile');
echo 'uploaded :)';
$data = array(
'category' => $this->input->post('category') ,
'product_name' => $this->input->post('name') ,
'description' => $this->input->post('description'),
'image' => $_FILES['userfile']['name']
);
}
$this->load->model('products');
$this->products->add_product($data);
}
$this->load->view('admin_page');
}

注意：要检查codeigniter 3的事情。
确保控制器和型号名称的首字母大写

将输入提交更改为按钮提交。

我会使用codeigniter＆＃39; <div class="container">
<?php echo validation_errors('<div class="alert alert-danger">', '</div>'); ?>
<?php if ($upload_errors) {?>
<div class="alert alert-info"><?php echo $upload_errors;?></div>
<?php }?>
<?php echo form_open_multipart('admin/admin_page');?>
<div class="form-group">
<label>Product name</label>
<input type="text" name="name" class="form-control" value="<?php echo set_value('name');?>" size="50">
</div>
<div class="form-group">
<label>Category</label>
<input type="text" name="category" value="<?php echo set_value('category');?>" class="form-control" size="50">
</div>
<div class="form-group">
<label>Description</label>
<textarea class="form-control" name="description" rows="3"></textarea>
</div>
<div class="form-group">
<label>Image</label>
<input type="file" name="userfile" size="20">
</div>
<div class="form-group">
<button type="submit" class="btn btn-default">Save</button>
</div>
<?php echo form_close();?>
