I am trying to upload a file in AngularJS using ng-upload but I am running into issues. My html looks like this:
<div class="create-article" ng-controller="PostCreateCtrl">
<form ng-upload method="post" enctype="multipart/form-data" action="/write" >
<fieldset>
<label>Category</label>
<select name="category_id" class="">
<option value="0">Select A Category</option>
<?php foreach($categories as $category): ?>
<option value="<?= $category -> category_id; ?>"><?= $category -> category_name; ?></option>
<?php endforeach; ?>
</select>
<label>Title</label>
<input type="text" class="title span5" name="post_title"
placeholder="A catchy title here..."
value="<?= $post -> post_title; ?>" />
<label>Attach Image</label>
<input type="file" name="post_image" />
<a href='javascript:void(0)' class="upload-submit: uploadPostImage(contents, completed)" >Crop Image</a>
<label>Body</label>
<div id="container">
<textarea id="mytextarea" wrap="off" name="post_content" class="span7" placeholder="Content..."><?= $post -> post_content; ?></textarea>
</div>
<div style='clear:both;'></div>
<label>Preview</label>
<div id='textarea-preview'></div>
</fieldset>
<div class="span7" style="margin: 0;">
<input type="submit" class="btn btn-success" value="Create Post" />
<input type="submit" class="btn btn-warning pull-right draft" value="Save as Draft" />
</div>
</form>
</div>
And my js controller looks like this:
ClabborApp.controller("PostCreateCtrl", ['$scope', 'PostModel',
function($scope, PostModel) {
$scope.uploadPostImage = function(contents, completed) {
console.log(completed);
alert(contents);
}
}]);
The problem I am facing is when the crop image is hit and it executes uploadPostImage, it uploads the entire form. Not desired behavior but I can make it work. The big problem is in the js the function uploadPostImage 'contents' parameters is always undefined, even when the 'completed' parameter comes back as true.
The goal is to only upload an image for cropping. What am I doing wrong in this process?
You can try ng-file-upload angularjs plugin (instead of ng-upload).
It's fairly easy to setup and deal with angularjs specifics. It also supports progress, cancel, drag and drop and is cross browser.
html
JS:
There's little-no documentation on angular for uploading files. A lot of solutions require custom directives other dependencies (jquery in primis... just to upload a file...). After many tries I've found this with just angularjs (tested on v.1.0.6)
html
Angularjs (1.0.6) not support ng-model on "input-file" tags so you have to do it in a "native-way" that pass the all (eventually) selected files from the user.
controller
The cool part is the undefined content-type and the transformRequest: angular.identity that give at the $http the ability to choose the right "content-type" and manage the boundary needed when handling multipart data.
In my case above mentioned methods work fine with php but when i try to upload files with these methods in node.js then i have some problem. So instead of using $http({..,..,...}) use the normal jquery ajax.
For select file use this
And in controller
