如何在PHP中檢查文件大小

Question

我正在嘗試使用echo $ _FILES ['photo'] ['size']檢查文件的大小，但未返回任何內容。

的HTML

<form method="POST" action="sendToDatabase.php">
    <fieldset>
        <legend>Artwork</legend>
        <label>Album Artwork</label>
        <input type="file" name="art" />
        <p>
            File must be saved as a .jpg file.<br />Please crop to 150px wide X 200px tall before uploading.
        </p>
    </fieldset>

    <input type="submit" name="submit" value="Submit Album" class="submitBtn" />
</form>

的PHP

<?php echo $_FILES['art']['size']; ?>

Answer 1

您需要在表單標簽中添加enctype="multipart/form-data"

enctype="multipart/form-data"


<form method="POST" action="sendToDatabase.php" enctype="multipart/form-data" >
