Hi your tutorial is very good but i have some problem , how to send image to server like normal submit form ? Can you show me some example ?
In the video description, I have given source code link . Actually that is my blog post link , you can visit the post . There I have given an example of sending images to server on simple submit. Because here is multiple image with preview. so you have to use ajax
@@web.tricks Ok bro, I will try that and thanks you so much
image += `
×
Delete
`;
I want to get id('Dlete') of button to set var x = document.getElementById('Dlete') and set x.style.display="block". But I can't.Please help me out.Thank you so much
I'm quite late but
To get of specific element just add a onclick event listener (ex. onclick="get_id(this)" )
and then define this function -
function get_id(element) {
var x = element.getAttribute('id'); // you can get any attribute value here like class., name or id
// now we can change the style or attribute value
x.style.display ='block';
// or we can change attribute value
x. setAttribute('id', 'new_id_here');
}
how to upload images after this tutorial?? i cant do it as i usually do using ajax jquery with php
use FormData() function and send files from images variable
@@web.tricks i added another function on form submit button but when i try to get files through document.getElementById("idName of File").files[0]; i get nothing must be cause of we resetting the form after each image upload or selected.
@@lazyexpertk5933 Form is reset everytime. so you can get images from images variable
here is the example -
function get_image_data() {
var form = new FormData(); for (let index = 0; index < images.length; index++) { form.append("file[" + index + "]", images[index]['file']); } return form; }
this function return all images then you can send it to the server
@@web.tricks then in php script i simply have to get it by
$fileName=$_FILES['file']['name'];
$fileTmpName=$_FILES['file']['tmp_name'];
??
@@lazyexpertk5933Yes it is right code but beacuse here you r uploading multiple images so you should use a loop in PHP

How to rotate multiple image using JavaScript and upload rotate multiple image rotate separate image please making video for this
You can rotate image using CSS transform property .
@@web.tricks no dear I want drag and drop form for multiple image using dropzone js and apply rotate image but I don't know how it is possible using JavaScript
I have one more question ! Do you just want to rotate image by applying CSS using JavaScript or rotate image itself.
@@web.tricks without CSS rotate image using JavaScript and dropzone js create the drag and drop form for multiple images . After this rotate particular image in multiple images and upload server side using PHP very urgent please
Wow, i'm from Argentina bro, this video is the better that I can watch, thanks. new suscriber
😊
please i tried to append list if images if like i click file input two or more times
only the last one is submitted the first ones are discarded
Can u show me your code here pastebin.com/
why doesn't the inputFile control show how many images were selected? Is it possible to make it display the number of selected images even though the d-none class is present?
It is possible. Select a element where you want to show counting, and show number of images in array, everytime you remove or select new images
how can upload the file to server?
File that you just need to send the server is saved in image variable.
So now use forEach loop and append file in the " new FormData() ". Then you can send this formdata to the server using ajax or with other
@@web.tricks because I used the smarty framework, this code was wrote in *.tpl, so I dont how can send the data to server.
Hey
In what you are facing problem.
In server side or client side
How to show selected images on Edit?
Can u explain??
@@web.tricks I need to implement this gallery in a CRUD so do you have an example to show the only selected images?
@@emanuelcordovamontiel1017 once watch this video ruclips.net/video/tU-hLqSDc-w/видео.html
After removing an image, if we try to select the same image change event is not triggered.
For this, you have to reset form after selecting any image
Please suggest sending data to another page with ajax.

Ok, soon you will find the download source code link in video description
@@web.tricks thanks bro.
Hello sir will you help me to show video as well as Image.
I m not understanding, what you want. Can your explain that what you want
@@web.tricks Actually I want to show video and images both . And while removing any video or images their value should be also removed. But in this code images value is not removing.
I have many more fields in my form so I don't want to reset form can you tell me how I can just send image data through ajax call?
Ok don't reset your form fields.
But for detecting changes in input-file, you have to reset that.
So for this first of select that input
document.querySelector("image").files = new DataTransfer().files;
This will do empty input-file every time.
@@web.tricks can you also tell me how to pass these images data to ajax to store them in database
@@RanaUsman89 use Javascript built-in class "FormData".
let form = new FormData();
images.forEach((e, i) => form.append(`file${i}`, e));
Now you can send this form data to the server.
Here is a example of send one image.
You can follow this.
www.webcodehindi.cf/2021/05/how-to-upload-images-using-jquery-ajax--php.html
@@web.tricks you are using send_image_data() in ajax data but this function is not defined
It is writing mistake.
replace "send_image_data()" with "get_image_data()"
Its a superb tutorial!! And very useful. Thanks a lot :)
There is a little hitch however with the next course of action. How to send images array (where all the images and related props are stored) to upload php file through ajax? FormData(this) does not work if list is updated / new images are added in installments. Please help
Why is it not working, where you getting error , on client side or server side ??
You can do like this.
let form = new FormData;
// images array
images.forEach((e,i) => {
// Here I have taken 'file' as a key
// You can access it on server - $_FILES['file']
form.append(`file[${ i }]`, e);
});
Now you can send 'form' variable to server using ajax.
Still any problem comment again 😀
@@web.tricks This is what I am trying:
JS file upload function:
let form_data = new FormData();
images.forEach((e,i) => {
form_data.append(`file[${ i }]`, e);
});
$.ajax({
type: "post",
url: "action/upload.php",
data: form_data,
contentType: false,
processData: false,
success: function (data) {
console.log(data);
}
});
If I try to console.log images (array) in the above upload function, it shows all the selected files (even after edit / delete / adding new files) as they are stored in images array. But cannot send them to the parser PHP file to upload.
Thanks a lot for the reply. I can tell from my experience that not many developers reply on RUclips. So it means a lot to me
@@souviknag your code is right, maybe you're making mistake on server side ( php code )
@@web.tricks Do you plan to make an extension to this video where we can learn how to handle the server side and upload the images? I have checked nearly all your videos and couldn't find one. Once again thanks :)
