le téléchargement d’image dans la page d’option d’administration de WordPress ne fonctionne pas

Je travaille sur un plugin qui a en back-end pour ajouter l’url du site ou du post et une courte description et en front-end afficher ensuite dans un widget, j’ai un bouton pour une petite image du post à télécharger mais ça n’a pas marché mais le même code fonctionne bien en php normal…

 $upload_errors = array(
                              // http://www.php.net/manual/en/features.file-upload.errors.php
                                UPLOAD_ERR_OK               => "No errors.",
                                UPLOAD_ERR_INI_SIZE     => "Larger than upload_max_filesize.",
                                UPLOAD_ERR_FORM_SIZE    => "Larger than form MAX_FILE_SIZE.",
                                UPLOAD_ERR_PARTIAL      => "Partial upload.",
                                UPLOAD_ERR_NO_FILE      => "No file.",
                                UPLOAD_ERR_NO_TMP_DIR => "No temporary directory.",
                                UPLOAD_ERR_CANT_WRITE => "Can't write to disk.",
                                UPLOAD_ERR_EXTENSION    => "File upload stopped by extension."
                             );


                           // process the form data
                           $tmp_file = $_FILES['file_upload']['tmp_name'];
                           $target_file = basename($_FILES['file_upload']['name']);
                           $upload_dir = "uploads";

                           // You will probably want to first use file_exists() to make sure
                           // there isn't already a file by the same name.

                           // move_uploaded_file will return false if $tmp_file is not a valid upload file
                           // or if it cannot be moved for any other reason
                           if(move_uploaded_file($tmp_file, $upload_dir."/".$target_file)) {
                           $message = "File uploaded successfully.";
                            } else {
                                $error = $_FILES['file_upload']['error'];
                                $message = $upload_errors[$error];

                                }

c’est le formulaire utilisé pour télécharger l’image

  <form action='' method='post' name="text_form" onsubmit="return Blank_TextField_Validator()" enctype="multipart/form-data">
                             <table class='form-table'><tr valign='top'>

                             </tr>
                             <tr>

le problème est avec l’url de téléchargement de fichier et c’est ainsi que je le répare .., maintenant cela fonctionne bien …

$tmp_file = $_FILES['file_upload']['tmp_name'];
                          $target_file = basename($_FILES['file_upload']['name']);
                          //$upload_dir = "D:softwares_installedwampwwwwordpresswp-contentpluginsbestofwebuploads";
                            $upload_dir =ABSPATH . "wp-content/plugins/bestofweb/uploads";
                            $up_urlp1="/wp-content/plugins/bestofweb/uploads";
                          // You will probably want to first use file_exists() to make sure
                          // there isn't already a file by the same name.

                          // move_uploaded_file will return false if $tmp_file is not a valid upload file
                          // or if it cannot be moved for any other reason
                          if(move_uploaded_file($tmp_file, $upload_dir."/".$target_file)) {
                                //$message = "File uploaded successfully.";
                                //echo $upload_dir."/".$target_file;
                                //echo  bloginfo('wpurl');
                                $up_url= $up_urlp1."/".$target_file;
                                //echo $up_url;
                                //if($message == "File uploaded successfully.")
                                //  {
                                //  $imgpath=$upload_dir.

                                //  }

                                   } else {
                                     $error = $_FILES['file_upload']['error'];
                                    // $message = $upload_errors[$error];
                                   }

Vous devriez regarder wp_handle_upload pour celui-ci.
L’exemple qui y est donné est très utile.

Pour enregistrer l’url, vous pouvez utiliser les lignes suivantes :

$upload_overrides = array( 'test_form' => false );
$source = wp_handle_upload( $_FILES['file'], $upload_overrides );

if ( $source )
    $input = serialize( $source );

J’espère que cela aide!
