我試圖下載文件中使用JavaScript和笨控制器我的笨web應用程序,它顯示了ASCII格式的文件內容,但無法下載文件直接如何在codeigniter中下載文件?
view.php
<a href="javascript:prd_download(this)">Download</a>
<img src="<?php echo site_url()."/../images/uploads/".$jobno."/thumb_".$prd_row->filename; ?>" alt="Loading Image..." >
<input type="checkbox" name="img_check" id="img_check" class="img_check" image="<?php echo $prd_row->filename ?>">
<script type="text/javascript">
function prd_download(ele)
{
var selected_images = $(".img_check:checked");
var job_no = $("#product_table").attr("jobno");
var image_name = new Array();
for(i = 0; i < selected_images.length; i++)
{
image_name[i] = $(selected_images[i]).attr('image');
}
$.get('<?php echo site_url('project_controller/file_download') ?>', {file_name : image_name, jobno : job_no});
}
</script>
Controller.php這樣
function file_download()
{
$url_para = $_GET['file_name'];
$job_no = $_GET['jobno'];
$this->load->helper('download');
$data = file_get_contents(site_url().'/../images/uploads/'.$job_no."/".$url_para[0]);
$name = 'myphoto.jpg';
force_download($name, $data);
}
我也通過改變路徑嘗試過,但它不工作...
'site_url()。'/ ../images/uploads /'似乎無效。嘗試從'/ images/uploads/..開始'' – Bora
檢查是否有任何控制檯錯誤? – Arunu
當我使用site_url()。'/ ../images/uploads /並在變量中打印這個變量值時,儘量使用'base_url()'而不是'site_url()' –
