Wordpress and AJAX - Upload image as featured
Please Try :
I have modify your code.
Jquery (added FormData() and append)
function apfaddpost() {
var fd = new FormData();
fd.append( "main_image", $('#main_image')[0].files[0]);
fd.append( "action", 'apf_addpost');
//Append here your necessary data
jQuery.ajax({
type: 'POST',
url: apfajax.ajaxurl,
data: fd,
processData: false,
contentType: false
success: function(data, textStatus, XMLHttpRequest) {
var id = '#apf-response';
jQuery(id).html('');
jQuery(id).append(data);
resetvalues();
},
error: function(MLHttpRequest, textStatus, errorThrown) {
alert(errorThrown);
}
});
}
in function.php
I have added file upload code
/******FILE UPLOAD*****************/
function upload_user_file( $file = array() ) {
require_once( ABSPATH . 'wp-admin/includes/admin.php' );
$file_return = wp_handle_upload( $file, array('test_form' => false ) );
if( isset( $file_return['error'] ) || isset( $file_return['upload_error_handler'] ) ) {
return false;
} else {
$filename = $file_return['file'];
$attachment = array(
'post_mime_type' => $file_return['type'],
'post_title' => preg_replace( '/\.[^.]+$/', '', basename( $filename ) ),
'post_content' => '',
'post_status' => 'inherit',
'guid' => $file_return['url']
);
$attachment_id = wp_insert_attachment( $attachment, $file_return['url'] );
require_once(ABSPATH . 'wp-admin/includes/image.php');
$attachment_data = wp_generate_attachment_metadata( $attachment_id, $filename );
wp_update_attachment_metadata( $attachment_id, $attachment_data );
if( 0 < intval( $attachment_id ) ) {
return $attachment_id;
}
}
return false;
}
now modify your function apf_addpost()
in function.php
function apf_addpost() {
foreach( $_FILES as $file )
{
if( is_array( $file ) ) {
$attach_id =upload_user_file(); //Call function
update_post_meta($pid,'_thumbnail_id',$attach_id);
}
}
}

I'm using wordpress with ajax in a frontend form and I'd need support for handling and uploading the featured image. My problem is specifically about the featured image. My html is something like:
<form id="msform" action="#" method="post" enctype="multipart/form-data"> //inputs of various nature <input type="file" name="main_image" id="main_image" multiple="false" value="" accept=".png, .jpg, .jpeg, .gif"/> <input type="submit" class="submit" value="Publish"/> </form>
I send data to a php function (following Wordpress methods) through this jquery:
function apfaddpost() { var formData = $('#msform').serialize(); formData.append('main_image', $('#main_image')[0].files[0]); //here should be the problem jQuery.ajax({ type: 'POST', url: apfajax.ajaxurl, data: formData + '&action=apf_addpost', //here I send data to the php function calling the specific action processData: false, contentType: false success: function(data, textStatus, XMLHttpRequest) { var id = '#apf-response'; jQuery(id).html(''); jQuery(id).append(data); resetvalues(); }, error: function(MLHttpRequest, textStatus, errorThrown) { alert(errorThrown); } }); }
My function php is something like
function apf_addpost() { require_once(ABSPATH . "wp-admin" . '/includes/image.php'); require_once(ABSPATH . "wp-admin" . '/includes/file.php'); require_once(ABSPATH . "wp-admin" . '/includes/media.php'); $file_handler = 'main_image'; $attach_id = media_handle_upload($file_handler,$pid ); update_post_meta($pid,'_thumbnail_id',$attach_id); }
Important to say: all the other data like title, description, tags are correctly serialized and sent. The problem is for the image. I've tried also to use the
$_FILES[]
handler without success and I suppose that my ajax code is not so great then. Can you help me? If you have any other workaround for this issue please share! Thanks in advance.[SOLVED] EDIT
Thanks to the answers below I've just changed my ajax into
function apfaddpost() { var fd = new FormData($('#msform')[0]); fd.append( "main_image", $('#main_image')[0].files[0]); fd.append( "action", 'apf_addpost'); //Append here your necessary data jQuery.ajax({ type: 'POST', url: apfajax.ajaxurl, data: fd, processData: false, contentType: false, success: function(data, textStatus, XMLHttpRequest) { var id = '#apf-response'; jQuery(id).html(''); jQuery(id).append(data); resetvalues(); }, error: function(MLHttpRequest, textStatus, errorThrown) { alert(errorThrown); } }); }
I've discovered that
FormData()
allows to serialize files, thing that.serialize()
method doesn't. Known that, it has been simple to move on. Thanks. -
middlelady about 8 yearsThank you @vrajesh! You've solved my problem. I didn't know that FormData() allows to serialize files. I'm beginner in Jquery / Ajax. Thanks Again!
