If you know a little bit PHP and MySQL there is no problem to accomplish your task. in your database should store only the file name (let say column name is image_name). you must define a constant with your upload folder something like: define("UPLOAD_DIR", "images_uploaded"); . when you will display the images you will refer as follows:

// do whatever (db) processing is necessarily

while ($obj = mysql_fetch_object($rez))
{
echo "<img src='./".UPLOAD_DIR."/".$obj->image_name."' alt='some alt desc'>";
}


hope it's useful ...

I wanted to how do we upload an image path(url) into the MySql database and call it through PHP.

When you upload an image, you upload it to a path. Store the path in a variable and at the time you upload, insert a record to the table containing the path.

Do we use the BLOB function, if yes, then how?

Nope. If you are uploading only the path, a fieldname of datatype varchar will do. eg. varchar(100).

I don't want to upload the image itself as it will burden the database.

Exactly ! Its not a good idea to upload images to the database.

When you upload an image, you upload it to a path. Store the path in a variable and at the time you upload, insert a record to the table containing the path.

Can you show me an example of doing this process. thanks.

I've visited the given url. But one question....

That's the path. Save that in the table.

How do I save it in the table. How does he path look like. Pls advise, still a bit blur on this part.

I don't know if you read (or understand) my previous post....
in the database you should keep only the file name. let say your file is image1.jpg and it is stored in {root}/images/uploaded_images/ + image1.jpg. why i think it's a better idea to keep only the filename? think what will happen if you store something like: "images/uploaded_images/image1.jpg" and one day you decide to rename your folder from "uploaded_images" to "uploads" ....

yes, I've read it but just a bit confusing. Anyhow thanks for your guide.

<form enctype="multipart/form-data" action="uploader.php" method="POST">
<input type="hidden" name="MAX_FILE_SIZE" value="100000" />
Choose a file to upload: <input name="uploadedfile" type="file" /><br />
<input type="submit" value="Upload File" />
</form>

Can't we customize this input box, I mean the length of the text area, rename the browse button. Can we?

you cannot use something like class='....' or style='...' to customize the file control .... it can be done but you have to dig a lot ....
