How to refresh images without page reloading after ajax call? - php

Question

I have a script below that uploads images to the server. Upon completion it updates the img source by html. The issue I'm having is that I wrote my php code to rename the files to a predefined name (ext-pix0.png, ext-pix1.png, ext-pix3.png, etc.) when they are being uploaded. Because of this, the pictures on the screen won't refresh even though the new images replaced the old ones when uploading is done. I also turn off no cache, but it doesn't work. How do I get around this issue?
SCRIPT
<script>
$('input[name="ext_pix[]"]').on('change',function(){
var account_list = $('#account_list').val();
var order_list = $('#order_list').val();
var id_list = $('#id_list').val();
var formData = new FormData($(this).parents('form')[0]);
$.ajax({
url: 'sql/ext-pix-upload.php',
type: 'POST',
data: formData,
async: false,
cache: false,
contentType: false,
processData: false,
success:function(data){
$('#ext-pix0').html('<img src="accounts/'+account_list+'/'+order_list+'/pix/'+id_list+'/ext-pix0.png" height="103.5%" width="100%"/>').fadeIn(500);
$('#ext-pix1').html('<img src="accounts/'+account_list+'/'+order_list+'/pix/'+id_list+'/ext-pix1.png" height="103.5%" width="100%"/>').fadeIn(500);
$('#ext-pix2').html('<img src="accounts/'+account_list+'/'+order_list+'/pix/'+id_list+'/ext-pix2.png" height="103.5%" width="100%"/>').fadeIn(500);

Answer 1

Clear the images first?
success:function(data){
$('#ext-pix0').html('');
$('#ext-pix1').html('');
$('#ext-pix2').html('');
$('#ext-pix3').html('');
$('#ext-pix0').html('<img src="accounts/'+account_list+'/'+order_list+'/pix/'+id_list+'/ext-pix0.png" height="103.5%" width="100%"/>').fadeIn(500);
$('#ext-pix1').html('<img src="accounts/'+account_list+'/'+order_list+'/pix/'+id_list+'/ext-pix1.png" height="103.5%" width="100%"/>').fadeIn(500);
$('#ext-pix2').html('<img src="accounts/'+account_list+'/'+order_list+'/pix/'+id_list+'/ext-pix2.png" height="103.5%" width="100%"/>').fadeIn(500);
$('#ext-pix3').html('<img src="accounts/'+account_list+'/'+order_list+'/pix/'+id_list+'/ext-pix3.png" height="103.5%" width="100%"/>').fadeIn(500);
},

Answer 2

Why don't you try to update img element in html file with id, inside the onSuccess() of ajax.
<img id="img_id" src="#"/>
OnSuccess function of Ajax,
success: function (data) {
$("#img_id").attr("src", data.pictureUrl);
}

Answer 3

Try like this:
success:function(data){
$('#ext-pix0').fadeOut('500', function(){
$(this).find("img").attr("src", "accounts/'+account_list+'/'+order_list+'/pix/'+id_list+'/ext-pix0.png");
$(this).fadeIn(500);
});
$('#ext-pix1').fadeOut('500', function(){
$(this).find("img").attr("src", "accounts/'+account_list+'/'+order_list+'/pix/'+id_list+'/ext-pix1.png");
$(this).fadeIn(500);
});
$('#ext-pix2').fadeOut('500', function(){
$(this).find("img").attr("src", "accounts/'+account_list+'/'+order_list+'/pix/'+id_list+'/ext-pix2.png");
$(this).fadeIn(500);
});
$('#ext-pix3').fadeOut('500', function(){
$(this).find("img").attr("src", "accounts/'+account_list+'/'+order_list+'/pix/'+id_list+'/ext-pix3.png");
$(this).fadeIn(500);
});
},

Answer 4

Please update what response you are getting in data in success function and update the src element only in ajax success. OR instead assign some class or ID to img tag and update only the src element.
<img class="ext-pix0" id="ext-pix0" src="images/profile/property-pix.png" height="103.5%" width="100%"/>
updated Script
success:function(data)
{
for(vari=0;i<data.length.i++)
{
$('#ext-pix'+i).attr(src,'data[i].url').fadeIn(500);
}
},

Answer 5

fadeOut "$('#ext-pix...')" before calling AJAX
success:function(data){
for(i=0;i<=3;i++){
$('#ext-pix'+i).html('');
let Image = $('<img/>',{src:'accounts/'+account_list+'/'+order_list+'/pix/'+id_list+'/ext-pix'+i+'.png' , style:'height:103.5%;width:100%';});
$('#ext-pix'+i).html(Image).fadeIn(500);
}
},
