如何使用Ajax上传多张图片？
[英]How to upload multiple image with Ajax?
问题描述
我有一个使用Kohana框架的网站。 尝试使用AJAX上传多张图片时出现问题。 我尝试了很多方法，但没有成功。 我认为问题出在函数_save_images($image)中：
if ($file = Upload::save($image, NULL, $directory))
因为我尝试echo此值，但收到如下结果：
网站不支持宽度小于900px的计算机
使用参数$image保存图像的功能是数组列表图像。
在ProductImage.php ：
protected function _save_images($image)
{
$directory = DOCROOT.'uploads/';
if ($file = Upload::save($image, NULL, $directory))
{
$filename = strtolower(Text::random('alnum', 20)).'.jpg';
Image::factory($file)
->resize(200, 200, Image::AUTO)
->save($directory.$filename);
// Delete the temporary file
unlink($file);
return $filename;
}
}
而且我有一个上传多张图片的功能。
public function action_create()
{
$user = Auth_Jelly::instance()->get_user();
$iduser = $user->id;
if($user->has_role('admin') || $user->check_permission($iduser,'CREATE_PRODUCT')==1){
$this->auto_render = false;
if(Request::$is_ajax)
{
$name_img = Security::xss_clean($_POST['name_img']);
$type_img = Security::xss_clean($_POST['type_img']);
$size_img = Security::xss_clean($_POST['size_img']);
$new_array = array();
foreach($name_img as $item){
$new_array['name'][] = $item;
}
foreach($type_img as $item){
$new_array['type'][] = $item;
}
foreach($size_img as $item){
$new_array['size'][] = $item;
}
$files = $new_array;
unset($new_array);
$ilosc = count($files['name'])-1;
for($i=0; $i<=$ilosc; $i++) {
$_FILES['image_list'.$i]['name'] = $files['name'][$i];
$_FILES['image_list'.$i]['type'] = $files['type'][$i];
$_FILES['image_list'.$i]['size'] = $files['size'][$i];
$array_new[] = array(
'name'=>$_FILES['image_list'.$i]['name'],
'type'=>$_FILES['image_list'.$i]['type'],
'error'=>0,
'size'=>$_FILES['image_list'.$i]['size'],
);
}
foreach ($array_new as $key => $value) {
$this->_save_images($value);
if($this->save_images($value)==FALSE){
echo "Faild Upload";
}else{
echo "Upload Success";
}
}
}
}else{
// Request::current()->redirect('admin/home/denied');
}
}
在ProductImage.js ：
$("#"+form).click(function(){
var image_list = Array();
var imageFiles = document.getElementById("image_list"),
filesLength = imageFiles.files.length;
for (var i = 0; i < filesLength; i++) {
image_list[i] = imageFiles.files[i].name;
}
var myFileList = document.getElementById('image_list').files;
var file ;
var name_img= Array();
var type_img= Array();
var size_img= Array();
// loop through files
for (var i = 0; i < myFileList.length; i++) {
// get item
file = myFileList.item(i);
//or
file = myFileList[i];
name_img[i]= file.name;
type_img[i]= file.type;
size_img[i]= file.size;
}
var local = window.location;
var val_content = tinyMCE.editors[0].getContent();
var language = $.trim($('#product-create-language option:selected').val());
var category = $.trim($('input[name=category]').val());
var status = $.trim($('input[name=createstatus]:checked').val());
var position = $.trim($('input[name=createposition]:checked').val());
var matches = [];
$(".addcheck:checked").each(function() {
matches.push(this.value);
});
if(matches.length>0)
matches=matches;
else
matches=null;
if(validateSpace(title,"<img src='"+base_url+"themes/admin/images/false.png' alt='false'>",titleinfo) && validateSpace(image,"<img src='"+base_url+"themes/admin/images/false.png' alt='false'>",imageinfo) && validateSpace(imagebig,"<img src='"+base_url+"themes/admin/images/false.png' alt='false'>",imagebiginfo) && validateSpace(imagemobile,"<img src='"+base_url+"themes/admin/images/false.png' alt='false'>",imagemobileinfo) && validateSpace(keywords,"<img src='"+base_url+"themes/admin/images/false.png' alt='false'>",keywordsinfo) && validateSpace(description,"<img src='"+base_url+"themes/admin/images/false.png' alt='false'>",descriptioninfo) && validateSpace(date,"<img src='"+base_url+"themes/admin/images/false.png' alt='false'>",dateinfo)){
var data = {name_img:name_img,type_img:type_img,size_img:size_img,category:category,mycolor: matches,language:language,title:$("#"+title).val(),image:$("#"+image).val(),imagebig:$("#"+imagebig).val(),imagemobile:$("#"+imagemobile).val(),fileupload:$("#"+fileupload).val(),price:$("#"+price).val(),pricesale:$("#"+pricesale).val(),idproduct:$("#"+idproduct).val(),color:$("#"+color).val(),packing:$("#"+packing).val(),cbmpsc:$("#"+cbmpsc).val(),size:$("#"+size).val(),container:$("#"+container).val(),excerpt:$("#"+excerpt).val(),content:val_content,keywords:$("#"+keywords).val(),description:$("#"+description).val(),date:$("#"+date).val(),status:status,position:position};
$(".product-content-create-total").fadeOut(); // hidden div content field register // children div of div class //register-form-center\\
$(".product-content-create").css("height","auto"); // set height/auto after hidden div class //register-form-center\\
$(".product-content-create-alert").html(""); // remove text div alert register // parent div of div id //register-form-content\\
$(".product-content-create-alert").css("margin-bottom","25px");
$(".product-content-create-alert").fadeIn("slow");
$(".product-content-create-alert").html('<img src="'+base_url+'themes/admin/images/loader.gif" alt="loader">');
$.ajax({
url: admin_url +"product/create",
type: "POST",
data: data,
cache: false,
success: function(html) {
console.log(html);
}
});
}else{
return false;
}
});
});
似乎有很多代码，所以，我希望任何人都可以帮助我。
更新：
在这里，我的表单代码包括“提交”按钮：
<form enctype="multipart/form-data" name="form-product-create" method="post">
<input type="file" id="image_list" name="image_list[]" multiple>
<input type="button" name="btnproductcreateclick" value=" " id="btn-product-create-click" style="margin-left:119px;" class="form-btn-create-click" />
</form>

<input name="file[]" type="file" />
<button class="add_more">Add More Files</button>
<input type="button" value="Upload File" id="upload"/>

$target_path = "uploads/";
$ext = explode('.', basename( $_FILES['file']['name'][$i]));
$target_path = $target_path . md5(uniqid()) . "." . $ext[count($ext)-1];
if(move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) {
echo "The file has been uploaded successfully <br />";
} else{
echo "There was an error uploading the file, please try again! <br />";
}
}

$('body').on('click', '#upload', function(e){
e.preventDefault();
var formData = new FormData($(this).parents('form')[0]);
$.ajax({
url: 'upload.php',
type: 'POST',
xhr: function() {

在您的代码错误看起来像在附近，
foreach ($array_new as $key => $value) {
$this->_save_images($value);
if($this->save_images($value)==FALSE){
echo "Faild Upload";
}else{
echo "Upload Success";
}
}
当您调用$this->_save_images($value); 您不保存上传图像的文件名。 $file_name = $this->_save_images($value); 然后保存此$file_name ，
foreach ($array_new as $key => $value) {
$file_name= $this->_save_images($value);
if($this->save_images($file_name)==FALSE){
echo "Faild Upload";
}else{
echo "Upload Success";
}
}

HTML表单必须具有带有“ post”值的“ method”属性。 因为只有在表单的method属性值为post时文件才会发送到服务器。
<form method="post" name="multiple_upload_form" id="multiple_upload_form" enctype="multipart/form-data" action="upload.php">
<input type="hidden" name="image_form_submit" value="1"/>
<label>Choose Image</label>
<input type="file" name="images[]" id="images" multiple >
<div class="uploading none">
<label> </label>
<img src="uploading.gif"/>
</div>
</form>
