I'm using this code in my plugin to add an extra field to the user profiles so that the user can upload an image. It uploads the file perfectly but the only problem is the part that has to delete the previous uploaded image doesn't work.
This is my code:
<?php
add_action( 'show_user_profile', 'my_show_extra_profile_fields' );
add_action( 'edit_user_profile', 'my_show_extra_profile_fields' );
function my_show_extra_profile_fields( $user ) {
?>
<script type="text/javascript">
var form = document.getElementById('your-profile');
form.encoding = "multipart/form-data";
form.setAttribute('enctype', 'multipart/form-data');
</script>
<table class="form-table">
<tr>
<th><label for="profile_photo">Upload your profile photo</label></th>
<td>
<p>
<input type="file" name="profile_photo" id="profile_photo" />
<input type="hidden" name="action" value="save">
<input type="submit" name="submitprofilephoto" id="submitprofilephoto" class="button" value="بارگذاری">
</p>
<span class="description">
<?php
$author_profile_photo = get_author_profile_photo($user->ID);
if(is_array($author_profile_photo)):
?>
<a href="<?php echo $author_profile_photo["url"];?>" target="_blank">
<img src="<?php echo $author_profile_photo["file"];?>" height="100" width="100" />
</a>
<?php
endif;
?>
</span>
</td>
</tr>
</table>
<?php
}
function get_author_profile_photo($user_ID) {
$author_data = get_the_author_meta( 'profile_photo', $user_ID );
$uploads = wp_upload_dir();
$author_data["file"] = $uploads["baseurl"] . $author_data["file"];
return $author_data;
}
add_action( 'personal_options_update', 'my_save_extra_profile_fields' );
add_action( 'edit_user_profile_update', 'my_save_extra_profile_fields' );
function my_save_extra_profile_fields( $user_id ) {
if ( !current_user_can( 'edit_user', $user_id ) )
return false;
$upload=$_FILES['profile_photo'];
$uploads = wp_upload_dir();
if(isset($_POST) && $_POST['submitprofilephoto']!='') {
if ($upload['tmp_name'] && file_is_displayable_image( $upload['tmp_name'] )) {
// handle the uploaded file
$overrides = array('test_form' => false);
$file=wp_handle_upload($upload, $overrides);
$file["file"] = $uploads["subdir"]."/".basename($file["url"]);
// Setup the array of supported file types. In this case, it's just Images.
$supported_types = array( 'image/jpeg', 'image/pjpeg', 'image/png' );
// Get the file type of the upload
$arr_file_type = wp_check_filetype(basename($upload['name']));
$uploaded_type = $arr_file_type['type'];
// Check if the type is supported. If not, throw an error.
if( $file && in_array($uploaded_type, $supported_types) ) {
if($upload['size'] > 204800) {
wp_die('<strong>ERROR</strong>: Maximum size allowed is 200KB.');
}
//remove previous uploaded file
$author_profile_photo = get_author_profile_photo($user_id);
@unlink($author_profile_photo["file"]);
// I even tried unlink without the @ and it still doesn't delete the file!
update_user_meta( $user_id, 'profile_photo', $file );
} else wp_die('<strong>ERROR</strong>: Allowd image formats are JPEG, JPG and PNG.');
} elseif (!file_is_displayable_image( $upload['tmp_name'] )) wp_die('<strong>ERROR</strong>: The file you selected is not an image!');
}
}
?>

Reset to default 0I figured it out! the problem is the path is not right! Thanks to this post : Alow users to delete uploaded images inside backend?
this function below helped :
function url_to_path_test($url){
$url=str_replace(rtrim(get_site_url(),'/').'/', ABSPATH, $url);
return $url;
}
So in my code if you change the remove previous image like this it will work :
//remove previous uploaded file
$author_profile_photo = get_author_profile_photo($user_id);
$url=str_replace(rtrim(get_site_url(),'/').'/', ABSPATH, $author_profile_photo["file"]);
@unlink($url);
I realized that the code below is a much better solution :
//remove previous uploaded file
$author_data = get_the_author_meta( 'profile_photo', $user_id );
$author_data["file"] = $uploads["path"] . $author_data["file"];
$imagepath = $author_data["file"];
@unlink($imagepath);
Here give full url of your file where it is located.
unlink(public_path('file/to/delete'))
as you are just providing file name in your code
@unlink($author_profile_photo["file"]);
and with if you want to prevent generating an error if the file does not exist.
wp_delete_attachment($attachment_id). Have you tried that? – fuxia ♦ Commented Oct 20, 2013 at 15:54
