Alright I have way to much time invested in this. I am new to PHP programming and trying to grasp the basics, but I am a little lost as of last night I was able to get a PHP form to upload basic data like a name address and stuff to my (MySQL) server.
But today I said let's do the next step which would be an image to the server. I have watched 3 videos on YouTube probably a 100 times just recoping code and trying it in so many different ways.
http://www.youtube.com/watch?v=CxY3FR9doHI
http://www.youtube.com/watch?v=vFZfJZ_WNC4&feature=relmfu
and still haven't been able to get it.
But long story short: I have a config.php file that connects to the server and here is the the code I'm running on the upload form page:
<html>
<head>
<title>Upload an image</title>
</head>
<body>
<form action="UploadContent.php" method="POST" enctype="multipart/form-data">
File:
<input type="file" name="image"> <input type="submit" value="Upload">
</form>
<?php
// connect to database
include"config.php";
// file properties
$file = $_FILES['image']['tmp_name'];
if (!isset($file))
echo "Please select a profile pic";
else
{
$image = addslashes(file_get_content($_FILES['image']['tmp_name']));
$image_name = addslashes($FILES['image']['name']);
$image_size = getimagesize($_FILES['image']['tmp_name']);
if ($image_size==FALSE)
echo "That isn't a image.";
else
{
$insert = mysql_query("INSERT INTO content VALUES ('','','','','','','','','','$image_name','$image',)");
}
}
?>
</body>
</html>
The reason for all the '', '', '', ''
on the insert line is because I have the name in the 10th field and the image blob in the 11th and all the ones leading up to that are first name, last name and random stuff like that. How can I fix this? It is returning the error:
Fatal error: Call to undefined function file_get_content() in /home/content/34/9587634/html/WEBPAGE/UploadContent.php on line 22
I don't know what to do.
<?php
$target_dir = "images/";
echo $target_file = $target_dir . basename($_FILES["image"]["name"]);
$post_tmp_img = $_FILES["image"]["tmp_name"];
$imageFileType = strtolower(pathinfo($target_file, PATHINFO_EXTENSION));
$post_imag = $_FILES["image"]["name"];
move_uploaded_file($post_tmp_img,"../images/$post_imag");
?>
<?php
$filename=$_FILES['file']['name'];
$filetype=$_FILES['file']['type'];
if($filetype=='image/jpeg' or $filetype=='image/png' or $filetype=='image/gif')
{
move_uploaded_file($_FILES['file']['tmp_name'],'dir_name/'.$filename);
$filepath="dir_name`enter code here`/".$filename;
}
?>
This code is very easy to upload file by php. In this code I am performing uploading task in same page that mean our html and php both code resides in the same file. This code generates new name of image name.
first of all see the html code
<form action="index.php" method="post" enctype="multipart/form-data">
<input type="file" name="banner_image" >
<input type="submit" value="submit">
</form>
now see the php code
<?php
$image_name=$_FILES['banner_image']['name'];
$temp = explode(".", $image_name);
$newfilename = round(microtime(true)) . '.' . end($temp);
$imagepath="uploads/".$newfilename;
move_uploaded_file($_FILES["banner_image"]["tmp_name"],$imagepath);
?>
I would recommend you to save the image in the server, and then save the URL in MYSQL database.
First of all, you should do more validation on your image, before non-validated files can lead to huge security risks.
Check the image
if (empty($_FILES['image']))
throw new Exception('Image file is missing');
Save the image in a variable
$image = $_FILES['image'];
Check the upload time errors
if ($image['error'] !== 0) {
if ($image['error'] === 1)
throw new Exception('Max upload size exceeded');
throw new Exception('Image uploading error: INI Error');
}
Check whether the uploaded file exists in the server
if (!file_exists($image['tmp_name']))
throw new Exception('Image file is missing in the server');
Validate the file size (Change it according to your needs)
$maxFileSize = 2 * 10e6; // = 2 000 000 bytes = 2MB
if ($image['size'] > $maxFileSize)
throw new Exception('Max size limit exceeded');
Validate the image (Check whether the file is an image)
$imageData = getimagesize($image['tmp_name']);
if (!$imageData)
throw new Exception('Invalid image');
Validate the image mime type (Do this according to your needs)
$mimeType = $imageData['mime'];
$allowedMimeTypes = ['image/jpeg', 'image/png', 'image/gif'];
if (!in_array($mimeType, $allowedMimeTypes))
throw new Exception('Only JPEG, PNG and GIFs are allowed');
This might help you to create a secure image uploading script with PHP.

Additionally, I suggest you use MYSQLI prepared statements for queries to improve security.
Thank you.
<?php
include("config.php");
if(isset($_POST['but_upload'])){
$name = $_FILES['file']['name'];
$target_dir = "upload/";
$target_file = $target_dir . basename($_FILES["file"]["name"]);
// Select file type
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
// Valid file extensions
$extensions_arr = array("jpg","jpeg","png","gif");
// Check extension
if( in_array($imageFileType,$extensions_arr) ){
// Insert record
$query = "insert into images(name) values('".$name."')";
mysqli_query($con,$query);
// Upload file
move_uploaded_file($_FILES['file']['tmp_name'],$target_dir.$name);
}
}

<form method="post" action="" enctype='multipart/form-data'>
<input type='file' name='file' />
<input type='submit' value='Save name' name='but_upload'>
</form>
Select the name or path of the image which you have stored in the database table and use it in the image source. Read More
<?php
$sql = "select name from images where id=1";
$result = mysqli_query($con,$sql);
while($row = mysqli_fetch_array($result)){
$image = $row['name'];
$image_src = "upload/".$image;
<img src='<?php echo $image_src; ?>' > echo '<br>';
}

Here is a basic example of how an image file with certain restrictions (listed below) can be uploaded to the server.
Checks for image size.
<?php
$newfilename = "newfilename";
if(isset($_FILES['image'])){
$errors= array();
$file_name = $_FILES['image']['name'];
$file_size =$_FILES['image']['size'];
$file_tmp =$_FILES['image']['tmp_name'];
$file_type=$_FILES['image']['type'];
$file_ext=strtolower(end(explode('.',$_FILES['image']['name'])));
$expensions= array("jpeg","jpg","png");
if(file_exists($file_name)) {
echo "Sorry, file already exists.";
}
if(in_array($file_ext,$expensions)=== false){
$errors[]="extension not allowed, please choose a JPEG or PNG file.";
}
if($file_size > 2097152){
$errors[]='File size must be excately 2 MB';
}
if(empty($errors)==true){
move_uploaded_file($file_tmp,"images/".$newfilename.".".$file_ext);
echo "Success";
echo "<script>window.close();</script>";
}
else{
print_r($errors);
}
}
?>
<html>
<body>
<form action="" method="POST" enctype="multipart/form-data">
<input type="file" name="image" />
<input type="submit"/>
</form>
</body>
</html>

You need to add two new file one is index.html, copy and paste the below code and other is imageup.php which will upload your image
<form action="imageup.php" method="post" enctype="multipart/form-data">
<input type="file" name="banner" >
<input type="submit" value="submit">
</form>
imageup.php
<?php
$banner=$_FILES['banner']['name'];
$expbanner=explode('.',$banner);
$bannerexptype=$expbanner[1];
date_default_timezone_set('Australia/Melbourne');
$date = date('m/d/Yh:i:sa', time());
$rand=rand(10000,99999);
$encname=$date.$rand;
$bannername=md5($encname).'.'.$bannerexptype;
$bannerpath="uploads/banners/".$bannername;
move_uploaded_file($_FILES["banner"]["tmp_name"],$bannerpath);
?>
The above code will upload your image with encrypted name
Change function file_get_content()
in your code to file_get_contents()
. You are missing 's' at the end of function name. That is why it is giving undefined function error.
Remove last unnecessary comma after $image
filed in line
"INSERT INTO content VALUES ('','','','','','','','','','$image_name','$image',)
Simple PHP file/image upload code on same page.
<form action="" method="post" enctype="multipart/form-data">
<table border="1px">
<tr><td><input type="file" name="image" ></td></tr>
<tr><td> <input type="submit" value="upload" name="btn"></td></tr>
</table>
</form>
<?php
if(isset($_POST['btn'])){
$image=$_FILES['image']['name'];
$imageArr=explode('.',$image); //first index is file name and second index file type
$rand=rand(10000,99999);
$newImageName=$imageArr[0].$rand.'.'.$imageArr[1];
$uploadPath="uploads/".$newImageName;
$isUploaded=move_uploaded_file($_FILES["image"]["tmp_name"],$uploadPath);
if($isUploaded)
echo 'successfully file uploaded';
else
echo 'something went wrong';
}
?>
