Good day all,
I have a form wil multiple fields in it. Also, the form is being submitted through form data method using ajax to a php file.
The following is the javascript code submitting the form data.
$(".update").click(function(){
$.ajax({
url: 'post_reply.php',
type: 'POST',
contentType:false,
processData: false,
data: function(){
var data = new FormData();
data.append('image',$('#picture').get(0).files[0]);
data.append('body' , $('#body').val());
data.append('uid', $('#uid').val());
return data;
}(),
success: function(result) {
alert(result);
},
error: function(xhr, result, errorThrown){
alert('Request failed.');
}
});
$('#picture').val('');
$('#body').val('');
});
And, the following is the actual form:
<textarea name=body id=body class=texarea placeholder='type your message here'></textarea>
<input type=file name=image id=picture >
<input name=update value=Send type=submit class=update id=update />
This form and javascript work good as they are. However, I am trying to be able to upload multiple files to the php file using this one single type=file field attribute. As it is now, it can only take one file at a time. How do I adjust both the form and the javascript code to be able to handle multiple files uploads?
Any help would be greatly appreciated.
Thanks!
Here is ajax, html and php global you can access. Let me know if it works for you.
// Updated part
jQuery.each(jQuery('#file')[0].files, function(i, file) {
data.append('file-'+i, file);
});
// Full Ajax request
$(".update").click(function(e) {
// Stops the form from reloading
e.preventDefault();
$.ajax({
url: 'post_reply.php',
type: 'POST',
contentType:false,
processData: false,
data: function(){
var data = new FormData();
jQuery.each(jQuery('#file')[0].files, function(i, file) {
data.append('file-'+i, file);
});
data.append('body' , $('#body').val());
data.append('uid', $('#uid').val());
return data;
}(),
success: function(result) {
alert(result);
},
error: function(xhr, result, errorThrown){
alert('Request failed.');
}
});
$('#picture').val('');
$('#body').val('');
});
Updated HTML:
<form enctype="multipart/form-data" method="post">
<input id="file" name="file[]" type="file" multiple/>
<input class="update" type="submit" />
</form>
Now, in PHP, you should be able to access your files:
// i.e.
$_FILES['file-0']
Here's another way.
Assuming your HTML is like this:
<form id="theform">
<textarea name="body" id="body" class="texarea" placeholder="type your message here"></textarea>
<!-- note the use of [] and multiple -->
<input type="file" name="image[]" id="picture" multiple>
<input name="update" value="Send" type="submit" class="update" id="update">
</form>
You could simply do
$("#theform").submit(function(e){
// prevent the form from submitting
e.preventDefault();
$.ajax({
url: 'post_reply.php',
type: 'POST',
contentType:false,
processData: false,
// pass the form in the FormData constructor to send all the data inside the form
data: new FormData(this),
success: function(result) {
alert(result);
},
error: function(xhr, result, errorThrown){
alert('Request failed.');
}
});
$('#picture').val('');
$('#body').val('');
});
Because we used [], you would be accessing the files as an array in the PHP.
<?php
print_r($_POST);
print_r($_FILES['image']); // should be an array i.e. $_FILES['image'][0] is 1st image, $_FILES['image'][1] is the 2nd, etc
?>
