Question

我正在尝试调整大小，然后在CodeIgniter中上传图像。它会上传图片，但不会调整图片大小。

<style> 
nav a {
text-decoration: none;
color: black;
overflow: hidden;
padding-left: 20px;
}

nav {
background-color: #ffffff;
height: 75px;
}

ul{
    margin-top:0;
    height:50px;
}

.right-menu {
    position:absolute;
    right:0;
    top:0;
    width:400px;
}

.left-menu {
    position:absolute;
    left:0;
    top:0;
    width:300px;
}

nav li {
list-style: none;
text-decoration: none;
padding: 2%;
align-items: center;
overflow: hidden;
display: inline-block;
height:100%;
}

nav img {  
margin-top: .8%;
margin-left: 2%;
height: 50px;
width: auto;
position: relative;
}
</style>
</head>
<body>
<nav> 
<ul  class="left-menu">
<li><img src="Lorem_Ipsum-logo-1662AFAE6D-seeklogo.com.gif" href="index.html"> </li>
<li><a href="index.html" class="homenav">Home</a></li>             
</ul>
<ul class="right-menu">
    <li><a href="#contact">Contact Us</a></li>
    <li><a href="about.html">About Us</a></li>
    <li><a href="photos.html">Products</a></li>                  
</ul>   
</nav>
</body>

首先，您尝试在实际上传文件之前调整的大小。其次，您需要为图像处理类提供上载图像的完整路径（再次，在您上传图像后）。第三，最好为不同的配置使用不同的变量名称：

$config['upload_path'] = './assets/uploads'; $config['allowed_types'] = 'gif|jpg|png|jpeg'; $this->load->library('upload', $config); if ($this->upload->do_upload('resim')) { $file_data = $this->upload->data(); $resize['image_library'] = 'gd2'; $resize['create_thumb'] = TRUE; $resize['maintain_ratio'] = TRUE; $resize['quality'] = '60%'; $resize['width'] = 200; $resize['height'] = 200; $resize['source_image'] = $file_data['full_path']; $this->load->library('image_lib', $resize); if (!$this->image_lib->resize()) { echo $this->image_lib->display_errors(); } } else { echo $this->upload->display_errors('<p>', '</p>'); }
