What are the potential pitfalls of using a popup window during file upload in PHP?

Potential pitfalls of using a popup window during file upload in PHP include compatibility issues with different browsers, potential for the popup window to be blocked by browser settings or extensions, and a less user-friendly experience for mobile users. To solve this issue, consider using an alternative method such as an AJAX file upload or a modal window within the same page. 

// Example of implementing a file upload using AJAX in PHP
<form id="uploadForm" action="upload.php" method="post" enctype="multipart/form-data">
    <input type="file" name="file">
    <input type="submit" value="Upload File">
</form>

<script>
document.getElementById('uploadForm').addEventListener('submit', function(e) {
    e.preventDefault();
    
    var formData = new FormData(this);
    
    fetch('upload.php', {
        method: 'POST',
        body: formData
    }).then(response => {
        console.log('File uploaded successfully');
    }).catch(error => {
        console.error('Error uploading file');
    });
});
</script>
