Hi, I'm still learning on how to upload and retrieve/display images. I have already have the idea on uploading an image onto the server. Well, I still have a problem when it comes to displaying the image which has been stored from the file server. I am actually using this method to display the image:
<?php
if(!isset($_SESSION)){
session_start();
}
$fileName=$_SESSION['uploadedImage'];
$fileType=$_GET['type'];
define("url", $_SERVER['DOCUMENT_ROOT']."practice/image upload test/htdocs/");
/* if($fileType=="image/jpeg"){
$image=imagecreatefromjpeg(url.$fileName);
header('Content-Type: image/jpeg');
imagejpeg($image);
}else if($fileType=="image/gif"){
$image=imagecreatefromgif(url.$filename);
header('Content-Type: image/gif');
imagegif($image);
}*/
$image=imagecreatefromjpeg(url.$fileName);
header('Content-Type: image/jpeg');
imagejpeg($image);
?>So, i'm using the function imagecreatefromjpeg() which creates an new image from a certain file(.jpg, .gif, etc.) and also the function imagejpeg() which outputs the image to browser or file.
Is there any method wherein I can display a certain image aside from the above code? Since the file that i'm trying to display is an image file.
Also if I remove the commented lines and make the last three lines a comment from the given code, the image isn't displayed.
Oh, here is the other .php file which is to be executed first:
<?php
if(!isset($_SESSION)){
session_start();
}
define("REP", $_SERVER['DOCUMENT_ROOT']."practice/image upload test/htdocs");
if(isset($_POST['submit'])){
if(is_uploaded_file($_FILES['fileupload']['tmp_name'])){
echo "temperory file name: " . $_FILES['fileupload']['tmp_name'] . "<br />";
echo "file name: " . $_FILES['fileupload']['name'] . "<br />";
echo "file size: " . $_FILES['fileupload']['size'] . "<br />";
echo "file type: " . $_FILES['fileupload']['type'] . "<br />";
$fileName=$_FILES['fileupload']['name'];
$tmpFileName=$_FILES['fileupload']['tmp_name'];
$fileType=$_FILES['fileupload']['type'];
$size=getimagesize($_FILES['fileupload']['tmp_name']);
$imgData=addslashes(file_get_contents($_FILES['fileupload']['tmp_name']));
/*getimagesize function returns an array where array index 0=width 1=height */
//check file type
/*
$data=base64_encode(addslashes(fopen($tmpFileName, "r", filesize($tmpFileName))));
echo "Data " . $data;
print "Strip " . stripslashes(base64_decode($data));
*/
if($fileType == "image/jpeg" || $fileType == "image/gif"){
if(move_uploaded_file($tmpFileName, REP . "/$fileName")){
$_SESSION['uploadedImage']=$fileName;
if(!isset($_GET['type'])){
$_GET['type']=$_FILES['fileupload']['type'];
}
echo "file successfully uploaded.<br />";
echo "<img src=displayImage.php width=20% />";
}else{
echo "something went wrong.";
}
}else{
echo "not a valid file type";
}
}else{
$err_Number = $_FILES['fileupload']['error'];
switch($err_Number){
case 1: echo "<b>UPLOAD_ERR_INI_SIZE: Err Num $err_Number </b>- There was an attempt to upload a file whose size exceeds the value specified by the <i>upload_max_filesize</i> directive.";
break;
case 2: echo "<b>UPLOAD_ERR_FORM_SIZE: Err Num $err_Number </b>- There was an attempt to upload a file whose size exceeds the value of the <i>max_file_size</i> directive, which can be embedded into the HTML form.";
break;
case 3: echo "<b>UPLOAD_ERR_PARTIAL: Err Num $err_Number </b>- A file is not completely uploaded. ";
break;
case 4: echo "<b>UPLOAD_ERR_NO_FILE: Err Num $err_Number </b>- No file specified.";
break;
}
}
}else{
