2 Oct 2009

In this tutorial you will learn to upload image file using PHP. Together you will learn to restrict file type. In this tutorial I am showing you example in which you can upload only jpg/jpeg images. It a very easy method I am going to show you and hope you will understand.

Start With Form :

<form action="" method="post" enctype="multipart/form-data" name="form1">


<p>

<input name="fileImage" type="file" id="fileImage">

</p>
<p>

<input name="save-image" type="submit" id="save-image" value="Upload Image">

</p>

</form>

Upload Code:

<?php


if(isset($_POST['save-image'])){
//Line Use to check if the buttton was pressed.
$fileName=$_FILES['fileImage']['name'];
//Getting file name and assigning it to $fileName variable
$fileType=$_FILES['fileImage']['type'];
//Getting file type and assigning it to $filetype variable
$fileSize=$_FILES['fileImage']['size'];
//Getting file size and assigning it to $filesize;
$tmpName=$_FILES['fileImage']['tmp_name'];
//Getting temporary name of file and assigning it to $tmpName
$maxsize=1048576;
//Defining maximum file size to 1Mb
$uploadDir=”upload/”;
//Define upload directory
$filePath=$uploadDir.$fileName;
//Defining file path so that we can use it on move_uploaded_file function
if(($fileType==”image/jpg”) || ($fileType==”image/jpeg”) || ($fileType==”image/pjpeg”)){
//Checking file type. Is the file jpg or not?
$result=move_uploaded_file($tmpName, $filePath);
//When file is jpg moving file to the upload directory from temp directory
}
if($result){
//If file move successfully then show message
echo “File Uploaded Successfully”;
}else{
//If file is invalid display message
echo “Invalid File Format”;
}
}

?>
