我想使用Ajax通过模式上传文件。我怎么能这样做?
我的模态:
<div id="addBtn" class="modal fade in" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h5 class="modal-title" id="myModalLabel">Add a medicine</h5>
</div>
<div class="modal-body">
<form>
<div class="form-group">
<label class="control-label mb-10">Generic Name</label>
<select class="form-control" name="medicine_id" id="medicine_id">
@foreach($items as $item)
<option value="{{$item->id}}" >{{$item->generic_name}}</option>
@endforeach
</select>
</div>
<div class="form-group">
<label class="control-label mb-10">Dosage Volume</label>
<input type="text" name="dosage_name" id="dosage-volume" class="form-control" placeholder="Example: 20mg">
</div>
<div class="form-group">
<label class="control-label mb-10">Form</label>
<input type="text" name="form" id="form" class="form-control" placeholder="Bottle, Tablet">
</div>
<div class="form-group">
<label class="control-label mb-10">Price Per piece</label>
<input type="text" name="price" id="price" class="form-control" placeholder="Price">
</div>
<div class="form-group">
<label class="control-label mb-10">Insert a photo</label>
<div class="panel-wrapper collapse in">
<div class="panel-body">
<div class="mt-20">
<input type="file" name="photo" id="input-file-now" class="dropify" >
</div>
</div>
</div>
</div>
</form>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-success waves-effect" data-dismiss="modal" id="save-dosage">Save</button>
<button type="button" class="btn btn-default waves-effect" data-dismiss="modal">Cancel</button>
</div>
</div>
<!-- /.modal-content -->
</div>
</div>
这是我的JavaScript文件:
function addDosage(url){
console.log(url);
$.ajax({
type:'POST',
url:url,
data:{
'medicine_id' : $('select#medicine_id').val(),
'dosage-volume' : $('#dosage-volume').val(),
'form' : $('[name=form]').val(),
'price' : $('[name=price]').val(),
'photo' : $('[name=photo]').val()
},
success:callback,
error:err
})
}
function callback(data){
console.log(data);
}
function err(xhr, reason, ex)
{
console.log(+xhr.status);
}
这是我的控制者:
public function storeDosage(ProductsRequest $request){
$file = $request->file('photo');
$fileName = uniqid() . $file->getClientOriginalName();
if(!file_exists('medicine/images')){
mkdir('medicine/images', 0777, true);
}
$file->move('medicine/images', $fileName);
if(!file_exists('medicine/images/thumbs')){
mkdir('medicine/images/thumbs', 0777, true);
}
$thumb = Image::make('medicine/images/' .$fileName)->resize(150,150)->save('medicine/images/thumbs/' . $fileName,50);
//post information to db
$dosage = $this->dosage;
$dosage->dosage_name = $request['dosage_name'];
$dosage->form = $request['form'];
$dosage->medicine_id = $request['medicine_id'];
$dosage->price = $request['price'];
$dosage->save();
$image = $dosage->photo()->create([
'dosage_id' => $request->input('id'),
'file_name' => $fileName,
'file_size' => $file->getClientSize(),
'file_mime' => $file->getClientMimeType(),
'file_path' => 'medicine/images/thumbs'. $fileName,
'created_by'=> auth()->user()->id,
]);
return redirect()->route('medicineList');
}
但它返回错误500.我认为Ajax不接受使用Bootstrap模式上传文件。
答案 0 :(得分:3)
您可以通过像这样的ajax使用bootstrap模式上传文件。
在您的表单标签中,使用属性enctype和表单html将如下所示:
<form enctype="multipart/form-data" id="modal_form_id" method="POST" >
<input type="file" name="documents">
</form>
Js代码:
var postData = new FormData($("#modal_form_id")[0]);
$.ajax({
type:'POST',
url:'your-post-url',
processData: false,
contentType: false,
data : postData,
success:function(data){
console.log("File Uploaded");
}
});
在控制器端,您可以使用以下功能上传图像。
if(Input::hasFile('documents')) {
$path = "directory where you wish to upload file";
$file_name= Input::file('documents');
$original_file_name = $file_name->getClientOriginalName();
$extension = $file_name->getClientOriginalExtension();
$fileWithoutExt = str_replace(".","",basename($original_file_name, $extension));
$updated_fileName = $fileWithoutExt."_".rand(0,99).".".$extension;
$uploaded = $file_name->move($path, $updated_fileName);
echo $updated_fileName;
}
