J'ai unplugin deformulaire WordPresset j'utilise media_handle_upload pourtélécharger lesfichierset obteniril y a desidentifiants directementet joint sesidentifiants aumessageen tant queméta date,j'ai utilisé ce qui suitpour lefaire:

Le code HTML du champ deformulaireest:

<input type="file" name="my_file_upload" id="my_file_upload">

Et le codephp était:

$attach_id = media_handle_upload( 'my_file_upload', $post_id ); if ( is_numeric( $attach_id ) ) { update_post_meta( $post_id, '_my_file_upload', $attach_id ); }

Ettoutfonctionnaitparfaitement.

Maisje nepeuxpasfairefonctionner lafonction media_handle_upload avecplusieursfichierstéléchargés.

Toute aide sera appréciée.
I have a WordPress form plugin and I use media_handle_upload to upload the files and get there ids directly and attached its ids to the post as a meta date, I used the following to did that:

The HTML of the form field is:

<input type="file" name="my_file_upload" id="my_file_upload">

And the php code was:

$attach_id = media_handle_upload( 'my_file_upload', $post_id ); if ( is_numeric( $attach_id ) ) { update_post_meta( $post_id, '_my_file_upload', $attach_id ); }

And everything was work perfectly.

Now I am trying to upload multiple files my HTML code is:

<input type="file" name="my_file_upload[]" id="my_file_upload[]" multiple="multiple">

But I cant make the media_handle_upload function work with multiple files upload.

Any help will be appreciated.

Si vous souhaitezimplémenter cela sans utiliser lefichier defonctions,vouspouvez utiliser la version simplifiée quej'aiproposée. Ceciest le codetestéfonctionne à 100%

 <form id="file_upload" method="post" action="#" enctype="multipart/form-data">
     <input type="file" name="my_file_upload[]" multiple="multiple">
     <input name="my_file_upload" type="submit" value="Upload" />
</form>

Placez le code PHP sur lapage où la soumission a lieu. Dansmon cas,sur lamêmepage que l'action duformulaireest définie sur "#"

 <?php if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    require_once( ABSPATH . 'wp-admin/includes/image.php' );
    require_once( ABSPATH . 'wp-admin/includes/file.php' );
    require_once( ABSPATH . 'wp-admin/includes/media.php' );

    $files = $_FILES["my_file_upload"];
    foreach ($files['name'] as $key => $value) {
        if ($files['name'][$key]) {
            $file = array(
                'name' => $files['name'][$key],
                'type' => $files['type'][$key],
                'tmp_name' => $files['tmp_name'][$key],
                'error' => $files['error'][$key],
                'size' => $files['size'][$key]
            );
            $_FILES = array("upload_file" => $file);
            $attachment_id = media_handle_upload("upload_file", 0);

            if (is_wp_error($attachment_id)) {
                // There was an error uploading the image.
                echo "Error adding file";
            } else {
                // The image was uploaded successfully!
                echo "File added successfully with ID: " . $attachment_id . "<br>";
                echo wp_get_attachment_image($attachment_id, array(800, 600)) . "<br>"; //Display the uploaded image with a size you wish. In this case it is 800x600
            }
        }
    }
} ?>

Cetteméthoden'inclura lesfichiers requis qu'une seulefois lorsque la soumission duformulaireestterminée au lieu de lesinclure chaquefois que lafonctionest appelée via laboucleforeach

If you want to implement this without using the functions file, you can use the streamlined version I came up with. This is the tested code works 100%

<form id="file_upload" method="post" action="#" enctype="multipart/form-data">
     <input type="file" name="my_file_upload[]" multiple="multiple">
     <input name="my_file_upload" type="submit" value="Upload" />
</form>

Place the PHP code on the page where the submit happens. In my case on the same page as the form action is set to "#"

<?php if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    require_once( ABSPATH . 'wp-admin/includes/image.php' );
    require_once( ABSPATH . 'wp-admin/includes/file.php' );
    require_once( ABSPATH . 'wp-admin/includes/media.php' );

    $files = $_FILES["my_file_upload"];
    foreach ($files['name'] as $key => $value) {
        if ($files['name'][$key]) {
            $file = array(
                'name' => $files['name'][$key],
                'type' => $files['type'][$key],
                'tmp_name' => $files['tmp_name'][$key],
                'error' => $files['error'][$key],
                'size' => $files['size'][$key]
            );
            $_FILES = array("upload_file" => $file);
            $attachment_id = media_handle_upload("upload_file", 0);

            if (is_wp_error($attachment_id)) {
                // There was an error uploading the image.
                echo "Error adding file";
            } else {
                // The image was uploaded successfully!
                echo "File added successfully with ID: " . $attachment_id . "<br>";
                echo wp_get_attachment_image($attachment_id, array(800, 600)) . "<br>"; //Display the uploaded image with a size you wish. In this case it is 800x600
            }
        }
    }
} ?>

This method will include the required files only once when the form submit is done instead of including them each time the function is called through foreach loop

EDIT: J'aienlevé le code `$post_thumbnail_id=wp_get_attachment_image_src ($ attachment_id,array (800,600));` carilestinutilepour l'exemple.Mais si vous souhaitez obtenir l'URL de l'image,cela vous aidera :)

EDIT: I have taken off the code `$post_thumbnail_id = wp_get_attachment_image_src($attachment_id, array(800, 600));` as it is unnecessary for the example. But if you wish to get the URL of the image, it will help you :)

Merci @ shady-m-rasmy J'ai utilisé le code que vous avezmentionné,et il semble que la deuxièmeboucleforeach (ci-dessous - dans lapartie dumodèlepersonnalisé)n'estpasnécessaire carellen'estexécutée qu'une seulefois.

foreach ($_FILES as $file => $array) { $newupload = my_handle_attachment($file,$pid); }

Donc çane part qu'avec

$newupload = my_handle_attachment( "my_file_upload", $pid);
Thanks @shady-m-rasmy I used the code you mentionned, and it seems that the second foreach loop (below - in the custom template part) is not necessary as it is only executed once.

foreach ($_FILES as $file => $array) { $newupload = my_handle_attachment($file,$pid); }

So it only leaves with

$newupload = my_handle_attachment( "my_file_upload", $pid);

$values = [ 'red', 'yellow', 'blue', 'pink' ]; foreach( $values as $value ) { // This method uses `add_post_meta()` instead of `update_post_meta()` add_post_meta( $item_id, 'color', $value ); }
Multiple entries for the same meta key

$values = [ 'red', 'yellow', 'blue', 'pink' ]; foreach( $values as $value ) { // This method uses `add_post_meta()` instead of `update_post_meta()` add_post_meta( $item_id, 'color', $value ); }

  I'm not sure this solves the problem here: the hardest part seems to be parsing the submitted files, not attaching multiple files to the post.

ici si vous utilisez unmodèlepersonnalisé au-delà de cela au début

 <?php
 if( 'POST' == $_SERVER['REQUEST_METHOD']  ) {
if ( $_FILES ) { 
    $files = $_FILES["my_file_upload"];  
    foreach ($files['name'] as $key => $value) {            
            if ($files['name'][$key]) { 
                $file = array( 
                    'name' => $files['name'][$key],
                    'type' => $files['type'][$key], 
                    'tmp_name' => $files['tmp_name'][$key], 
                    'error' => $files['error'][$key],
                    'size' => $files['size'][$key]
                ); 
                $_FILES = array ("my_file_upload" => $file); 
                foreach ($_FILES as $file => $array) {              
                    $newupload = my_handle_attachment($file,$pid); 
                }
            } 
        } 
    }

}
?>

dansfunction.php

 function my_handle_attachment($file_handler,$post_id,$set_thu=false) {
  // check to make sure its a successful upload
  if ($_FILES[$file_handler]['error'] !== UPLOAD_ERR_OK) __return_false();

  $attach_id = media_handle_upload( $file_handler, $post_id );
  if ( is_numeric( $attach_id ) ) {
    update_post_meta( $post_id, '_my_file_upload', $attach_id );
  }

here if you use custom template past this in the begining

<?php
 if( 'POST' == $_SERVER['REQUEST_METHOD']  ) {
if ( $_FILES ) { 
    $files = $_FILES["my_file_upload"];  
    foreach ($files['name'] as $key => $value) {            
            if ($files['name'][$key]) { 
                $file = array( 
                    'name' => $files['name'][$key],
                    'type' => $files['type'][$key], 
                    'tmp_name' => $files['tmp_name'][$key], 
                    'error' => $files['error'][$key],
                    'size' => $files['size'][$key]
                ); 
                $_FILES = array ("my_file_upload" => $file); 
                foreach ($_FILES as $file => $array) {              
                    $newupload = my_handle_attachment($file,$pid); 
                }
            } 
        } 
    }

}
?>

in function.php

function my_handle_attachment($file_handler,$post_id,$set_thu=false) {
  // check to make sure its a successful upload
  if ($_FILES[$file_handler]['error'] !== UPLOAD_ERR_OK) __return_false();

  require_once(ABSPATH . "wp-admin" . '/includes/image.php');
  require_once(ABSPATH . "wp-admin" . '/includes/file.php');
  require_once(ABSPATH . "wp-admin" . '/includes/media.php');

  $attach_id = media_handle_upload( $file_handler, $post_id );
  if ( is_numeric( $attach_id ) ) {
    update_post_meta( $post_id, '_my_file_upload', $attach_id );
  }
  return $attach_id;

Doesn't this overwrite the global $_FILES variable?

@ReLeaf Ceci _ devrait_ écraser la variableglobale $ _FILES.`media_handle_upload ()` recherche `$ _FILES [$file_handler]`

@ReLeaf This _should_ overwrite the global $_FILES variable. `media_handle_upload()` looks for `$_FILES[$file_handler]`

This snippet works perfect, EXCEPT on Android WebView when trying to upload multiple files (single file is ok).
