In your endeavors with PHP, you've encountered a roadblock when attempting to upload multiple files. Let's explore how you can overcome this challenge by delving into the provided code snippet and addressing the issue.
The HTML file features a form with a file input field that allows for multiple selections (multiple=multiple). A button triggers the sendfile() function upon clicking, initiating the uploading process. The sendfile() function creates a FormData object and iterates through the selected files, appending them to the data payload. jQuery's ajax() function is then utilized to send the data to uploadfile.php for handling.
The PHP file (uploadfile.php) defines a target directory and attempts to move uploaded files one by one.
The provided code mistakenly attempts to move each uploaded file one at a time, which works for a single file but not for multiple selections. The crux of the issue lies in the for loop's construction.
The appropriate fix is to use a more inclusive foreach loop to iterate through the uploaded files. This approach ensures that each file is processed and moved to the target directory.
To achieve this, the following adjustments to uploadfile.php are required:
<code class="php">foreach ($_FILES['myfile']['name'] as $i => $name) { if (move_uploaded_file($_FILES['myfile']['tmp_name'][$i], $target . $name)) { echo 'Successfully copied'; } else { echo 'Sorry, could not copy'; } }</code>
This refined version correctly handles multiple files by iterating through each file's name and temporary path, enabling them to be moved individually. The loop ensures that every selected file is accounted for and moved to the specified target directory.
