I am using dropzone in my Code Igniter Project.
With every drag of a file, dropzone creates an ajax request and my files is getting stored on the server too. But now, my requirement is that I want to send additional data (DYNAMIC) alongside the file. With the use of params, Only static datas can be sent, but the data I want to send will be changing everytime.
This is how my code looks:
<script>
Dropzone.autoDiscover = false;
Dropzone.options.attachment = {
init: function(){
this.on('removedfile',function(file){
// console.log('akjsdhaksj');
var fileName = file.name;
$.ajax({
type: 'POST',
url: "<?php echo BASE_URL.'index.php/admin/mail_actions/deleteFile' ?>",
data: "id="+fileName,
dataType: 'html'
});
});
},
// params: {
// customerFolder: $('#toValue').substr(0, toValue.indexOf('@')),
// },
dictDefaultMessage:"Click / Drop here to upload files",
addRemoveLinks: true,
dictRemoveFile:"Remove",
maxFiles:3,
maxFilesize:8,
}
$(function(){
var uploadFilePath = "<?php echo BASE_URL.'index.php/admin/mail_actions/uploadFile' ?>";
var myDropzone = new Dropzone("div#attachment", { url: uploadFilePath});
});
</script>
Anyway I can achieve it?
I got it. This is what I had to use
myDropzone.on('sending', function(file, xhr, formData){
formData.append('userName', 'bob');
});
Abhinav has the right and working answer I only want to give a second option to use it in the options object (for example if you have multiple Dropzone sections on one page.)
myDropzone.options.dropzoneDivID = {
sending: function(file, xhr, formData){
formData.append('userName', 'Bob');
}
};
In case you have a nested payload object - e.g. to add a name to your file and your api only accepts something like this
{
someParameter: {
image: <my-upload-file>,
name: 'Bob'
}
}
your dropzone setup would look like this
var myDropzone = new Dropzone("div#attachment", {
url: uploadFilePath,
paramName: 'someParameter[image]'
});
myDropzone.on('sending', function(file, xhr, formData){
formData.append('someParameter[image]', file);
formData.append('someParameter[userName]', 'bob');
});
I only added this as there was no example for nested parameters documented since now.
