嗨,我想在我的网站上为每个用户上传一个 100 x 100 像素的图像作为徽标。它可以在我的本地主机上工作,但不能在线工作(图片未上传)。这个概念很简单,我只需上传它并根据他们的 ID 重命名图像,然后将其显示在他们的页面上供他们查看。另一件事,本地主机版本更改了指定路径上的图像,但在上传后不显示它,但有时它工作得很好。好吧,这不是一个大案子,我只是认为这可能是解决这个问题的线索。到目前为止,这是我的代码:
这是在顶部声明的:
$data['base'] = $this->config->base_url();
$data['check_error'] = false;
$data['error_message'] = array();
$data['id'] = $this->session->userdata('id');
这是代码:
if (isset($_FILES['userfile']) && is_uploaded_file($_FILES['userfile']['tmp_name'])){
$new_name = $data['id'];
$config['upload_path'] = './Logos/';
$config['allowed_types'] = 'jpg|png|gif';
$config['encrypt_name'] = true;
$config['max_size'] = '100';
$config['max_width'] = '100';
$config['max_height'] = '100';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload())
{
array_push($data['error_message'], "You have the following errors in your entry:\n");
array_push($data['error_message'], "- Logo must be 100x100 pixels in size not exceeding 100KB with JPG,PNG or GIF format");
array_push($data['error_message'], "\nLogo upload failed.");
$data['check_error'] = true;
}
else
{
$data = array('upload_data' => $this->upload->data());
//DO UPDATE PART HERE
$file = $data['upload_data']['file_name'];
rename($config['upload_path'] . $file, $config['upload_path'] .$new_name.'.jpg');
//GO TO SETTINGS
$this->load->helper('url');
redirect($data['base'].'settings');
}
}
HTML:
<tr>
<td><p class="titles">Logo</p></td>
<td>
<div>
<input type="text" id="fileName" class="file_input_textbox" readonly="readonly">
<div class="file_input_div">
<input type="button" value="Browse" class="file_input_button" />
<input type="file" class="file_input_hidden" onchange="javascript: document.getElementById('fileName').value = this.value" id="upload" name="userfile" />
</div>
</div>
</td>
</tr>
<tr>
<td>
</td>
<td>
<p class="titles">100px x 100px jpg, png or gif only.</p>
</td>
</tr>
<tr>
<td><p class="titles">Current Logo</p></td>

<img src="<?php if(is_array(@getimagesize($base."Logos/".$id.".jpg"))){echo $base."Logos/".$id.".jpg";}else{echo $base."Logos/default.jpg";} ?>" style="margin:0px 0px 0px 90px;"/>
</td>
</tr>
我也在本地使用 PHP 中的 CodeIgniter_2.1.3 和 5.4.3,在线使用 5.2.17。疯了哈哈!
