PHP file upload can't send POST data on same form
I have a basic username & password form which also allows you to upload an image with it. There's a create button, which takes the user to uploader.php which both uploads the image and inputs the username & password into the database.
Within the form tag:
< form enctype="multipart/form-data" method="POST" action="uploader.php?uploader=avatar&username=< ?php echo $_POST['username']; ?>" >
The problem:
The username won't post, nor any other posts for that matter. All fields are inside the form. I have checked PHP file upload form cannot submit a POST variable? and within php.ini post_max_size = 8M, and upload_max_filesize = 2M
Use <input type="hidden"/> to post username and other info.
<form enctype="multipart/form-data" method="POST" action="uploader.php">
<input type="hidden" name="uploader" value="avatar"/>
<input type="hidden" name="username" value="<?php echo $_POST['username']; ?>" />
...
</form>
Sample.php
<form enctype="multipart/form-data" method="POST" action="uploader.php">
<br/>Username : <input type="text" name="username"/>
<br/>Password : <input type="password" name="password"/>
<input type="hidden" name="uploader" value="avatar"/>
<br/>File : <input type="file" name="file"/>
<br/><input type="submit"/>
</form>
uploader.php
<?php
print_r($_POST) // debug $_POST
print_r($_FILES) // file
//OR
echo $_POST["username"];
$file=$_FILES["file"];
print_r(file);
?>
It sounds like you want to submit the username and password and upload a file all in the one submit.
If this is what you want, you need something like the following:
<form enctype="multipart/form-data" method="POST" action="uploader.php">
<input type="text" name="username" value="" />
<input type="password" name="password" value="" />
<input type="file" name="uploaded" />
...
</form>
The username and password will be available in $_POST[] and the file will be present in $_FILES[] .
I had this problem when the files I was attempting to upload were larger than the max filesize PHP was accepting. Look at:
ini_get('post_max_size')
and
ini_get('upload_max_filesize')
to see if your file is too big. My solution was to use empty($_POST) to determine if the file was too big (or some other posting problem occurred) and throw an Exception.
