PHP, using $_FILES and $_POST at the same time - php

Question

I have a problem in using $_FILES and $_POST at the same the because I have a form to upload an image and some data bus when I use one of them it works but when I used the other one id doesn't work.
my code is :
<?php
include 'debugging.php';
//phpinfo();
echo '<br />';
echo '<h1>Image Upload</h1>';
//create a form with a file upload control and a submit button
echo <<<_END
<br />
<form method='post' action='uplaodex.php' enctype='multipart/form-data'>
Select File: <input type='file' name='picName' size='50' />
name: <input type='text' name='usName' size='50' />
username : <input type='text' name='usUsername' size='50' />
pass: <input type='password' name='usPass' size='50' />
email: <input type='text' name='usEmail' size='50' />
<br />
<input type='submit' value='Upload' />
<input type="hidden" name="submit" value="1" />
</form>
<br />
_END;
//above is a special use of the echo function - everything between <<<_END
//and _END will be treated as one large echo statement
//$_FILES is a PHP global array similar to $_POST and $_GET
if (isset($_FILES['picName'])and isset($_POST['submit'])) {
//we access the $_FILES array using the name of the upload control in the form created above
//
//create a file path to save the uploaded file into
$name = "images//" . $_FILES['picName']['name']; //unix path uses forward slash
//'filename' index comes from input type 'file' in the form above
//
//move uploaded file from temp to web directory
if (move_uploaded_file($_FILES['picName']['tmp_name'], $name)) {
// Create the file DO and populate it.
include 'Do_profile.php';
$file = new Do_profile();
//we are going to store the file type and the size so we get that info
$type = $_FILES['picName']['type'];
$size = $_FILES['picName']['size'];
$usName = trim($_POST['usName']);
$usUsername = trim($_POST['usUsername']);
$usPass = trim($_POST['usPass']);
$usEmail = trim($_POST['usEmail']);
$file->FileName = $name; //$name is initialised previously using $_FILES and file path
$file->FileSize = $size;
$file->Type = $type;
$file->usName = $usName;
$file->usUsername = $usUsername;
$file->usPass = $usPass;
$file->usEmail = $usEmail;
if ($file->save()) {
//select the ID of the image just stored so we can create a link
//display success message
echo "<h1> Thankyou </h1><p>Image stored successfully</p>";
//this above line of code displays the image now stored in the images sub directory
echo "<p>Uploaded image '$name'</p><br /><img src='$name' height='200' width='200'/>";
//create alink to the page we will use to display the stored image
echo '<br><a href="Display.php?id=' . $fileId . '">Display image ' .
$file->FileName . '</a>';
} else
echo '<p class="error">Error retrieving file information</p>';
}
else {
echo '<p class="error"> Oh dear. There was a databse error</p>';
}
} else {
//error handling in case move_uploaded_file() the file fails
$error_array = error_get_last();
echo "<p class='error'>Could not move the file</p>";
// foreach($error_array as $err)
// echo $err;
}
echo "</body></html>";
?>
I don't know what is the problem, any help??

Answer 1

Everything inside that if (isset($_FILES['picName'])and isset($_POST['submit'])) doesn't work because the superglobal $_FILES is probably not having a key named picName. To check this out, try var_dump-ing the $_FILES, like var_dump($_FILES);
By the output of the var_dump you'd get to know if there is any content inside $_FILES. And if it is populated, just see what the key name is and, access the file by using that key.
But if the array is empty, there may be some mis-configurations in PHP, or APACHE.
One possible fix would be setting file_uploads = On in the ini file for php.
Hope it helps!

You have to validate the size of the file if you want to do an isset. I don't know if this is works, but the better way for do that is check first the size for validate if isset or was send to the server.
Then, in your <form method='post' action='uplaodex.php' enctype='multipart/form-data'> you have to create another PHP file with the name uplaodex.php where you'll send al the data. So, your code with be like the below code following and considering the step 1. This will be your uploadex.php
$name_file = $_FILES['picName']['name'];
$type = $name_file['type'];
$size = $name_file['size'];
$tmp_folder = $name_file['tmp'];
$usName = trim($_POST['usName']);
$usUsername = trim($_POST['usUsername']);
$usPass = trim($_POST['usPass']);
$usEmail = trim($_POST['usEmail']);
if ( $size > 0 ) {
//REMOVE another slash images//
$name = "images/" . $name_file; //unix path uses forward slash
//'filename' index comes from input type 'file' in the form above
//
//move uploaded file from temp to web directory
if ( move_uploaded_file($tmp_folder, $name) ) {
// Create the file DO and populate it.
include 'Do_profile.php';
$file = new Do_profile();
$file->FileName = $name; //$name is initialised previously using $_FILES and file path
$file->FileSize = $size;
$file->Type = $type;
$file->usName = $usName;
$file->usUsername = $usUsername;
$file->usPass = $usPass;
$file->usEmail = $usEmail;
if ($file->save()) {
//USE PRINTF
printf('<h1> Thankyou </h1><p>Image stored successfully</p><br>
<p>Uploaded file: %s</p>. <img src="%s" height="200" width="200" />',
$name_file, $name );
#WHAT IS $fileId? In which moment was define?
//echo '<br><a href="Display.php?id=' . $fileId . '">Display image ' .
$file->FileName . '</a>';
}
else
echo '<p class="error">Error retrieving file information</p>';
}
else {
echo '<p class="error"> Oh dear. There was a databse error</p>';
} //ENDIF OF if (move_uploaded_file($_FILES['picName']['tmp_name'], $name))
} //ENDIF OF if ( $size > 0 )
#ELSE OF YOUR if ( $size > 0 )
else {
//error handling in case move_uploaded_file() the file fails
$error_array = error_get_last();
echo "<p class='error'>Could not move the file</p>";
// foreach($error_array as $err)
// echo $err;
}

I solved the problem, you can't perform $_FILES and $_post at the same time or one of them inside the other.
start with $_Post and then $_FILES and outside the $_FILES run your saving function
thats it
