I am implementing a form to get personal details of user and an image of user for DP. How do i display it on next page if data is submitted correctly.
This can help you,
The upload form.
<html>
<head><title>File Upload To Database</title></head>
<body>
<h2>Please Choose a File and click Submit</h2>
<form enctype="multipart/form-data" action="<?php echo htmlentities($_SERVER['PHP_SELF']);?>" method="post">
<input type="hidden" name="MAX_FILE_SIZE" value="99999999" />
<div><input name="userfile" type="file" /></div>
<div><input type="submit" value="Submit" /></div>
</form>
</body></html>
Uploading the image.
<?php
/*** check if a file was submitted ***/
if(!isset($_FILES['userfile']))
{
echo '<p>Please select a file</p>';
}
else
{
try {
upload();
/*** give praise and thanks to the php gods ***/
echo '<p>Thank you for submitting</p>';
}
catch(Exception $e)
{
echo '<h4>'.$e->getMessage().'</h4>';
}
}
?>
The upload function
<?php
/**
*
* the upload function
*
* @access public
*
* @return void
*
*/
function upload(){
/*** check if a file was uploaded ***/
if(is_uploaded_file($_FILES['userfile']['tmp_name']) && getimagesize($_FILES['userfile']['tmp_name']) != false)
{
/*** get the image info. ***/
$size = getimagesize($_FILES['userfile']['tmp_name']);
/*** assign our variables ***/
$type = $size['mime'];
$imgfp = fopen($_FILES['userfile']['tmp_name'], 'rb');
$size = $size[3];
$name = $_FILES['userfile']['name'];
$maxsize = 99999999;
/*** check the file is less than the maximum file size ***/
if($_FILES['userfile']['size'] < $maxsize )
{
/*** connect to db ***/
$dbh = new PDO("mysql:host=localhost;dbname=testblob", 'username', 'password');
/*** set the error mode ***/
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
/*** our sql query ***/
$stmt = $dbh->prepare("INSERT INTO testblob (image_type ,image, image_size, image_name) VALUES (? ,?, ?, ?)");
/*** bind the params ***/
$stmt->bindParam(1, $type);
$stmt->bindParam(2, $imgfp, PDO::PARAM_LOB);
$stmt->bindParam(3, $size);
$stmt->bindParam(4, $name);
/*** execute the query ***/
$stmt->execute();
}
else
{
/*** throw an exception is image is not of type ***/
throw new Exception("File Size Error");
}
}
else
{
// if the file is not less than the maximum allowed, print an error
throw new Exception("Unsupported Image Format!");
}
}
?>
Displaying the image
<?php
/*** some basic sanity checks ***/
if(filter_has_var(INPUT_GET, "image_id") !== false && filter_input(INPUT_GET, 'image_id', FILTER_VALIDATE_INT) !== false)
{
/*** assign the image id ***/
$image_id = filter_input(INPUT_GET, "image_id", FILTER_SANITIZE_NUMBER_INT);
try {
/*** connect to the database ***/
$dbh = new PDO("mysql:host=localhost;dbname=testblob", 'username', 'password');
/*** set the PDO error mode to exception ***/
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
/*** The sql statement ***/
$sql = "SELECT image, image_type FROM testblob WHERE image_id=$image_id";
/*** prepare the sql ***/
$stmt = $dbh->prepare($sql);
/*** exceute the query ***/
$stmt->execute();
/*** set the fetch mode to associative array ***/
$stmt->setFetchMode(PDO::FETCH_ASSOC);
/*** set the header for the image ***/
$array = $stmt->fetch();
/*** check we have a single image and type ***/
if(sizeof($array) == 2)
{
/*** set the headers and display the image ***/
header("Content-type: ".$array['image_type']);
/*** output the image ***/
echo $array['image'];
}
else
{
throw new Exception("Out of bounds Error");
}
}
catch(PDOException $e)
{
echo $e->getMessage();
}
catch(Exception $e)
{
echo $e->getMessage();
}
}
else
{
echo 'Please use a real id number';
}
?>
