使用php-pdf和jpeg进行图像上传文件类型验证

Question

I have the following script for part of a form which allows a file upload, full script is here: Issue with image upload php: undefined index . It works ok in that it stops the script if there is no file selected and uploads when the form is fully populated (for logged in users only)

What I am trying to do with no luck so far, however is confine the upload type to pdf and jpeg only.

Any suggestions welcome

    <?php         
    if (is_uploaded_file ($_FILES ['image']['tmp_name'])) {
    if (move_uploaded_file($_FILES ['image']['tmp_name'], 
    "uploads/{$_FILES['image']['name']}")) { // Move the file over.
    echo '<p>The file has been uploaded!</p>';
    } else { // Couldn't move the file over.
    echo '<p><font color="red"> The thumbnail image could not be uploaded.</font></p>';
    $i = FALSE;
    }
    $i = $_FILES['image']['name'];
    } else {
    $i = FALSE;
    }
    ?>      

Answer 1

你应该阅读手册$ _FILE类型它会是这样的：

if ($_FILES['file']['type'] == 'image/jpeg')  && ($_FILES["file"]["type"] == "application/pdf")

Answer 2

This will do the trick for you...

    <?php
    if(isset($_FILES['image'])&&(!empty($_FILES['image']))){  
    if (($_FILES['image']['type']== "image/jpeg")||($_FILES['image']['type'] == "application/pdf")){
$filename =$_FILES['image']['name'];
    $copy = copy($_FILES['image']['tmp_name'], "uploads/".$filename);
    if($copy){
    echo '<p>The file has been uploaded!</p>';
    }else{
    echo 'File is not a jpeg or pdf';
    }
    }else{
    echo '<p><font color="red"> The thumbnail image could not be uploaded.</font></p>';
    }
    }else{
    echo 'no image is selected';
    } 
    ?>
