</html>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.
http://www.tizag.com/phpT/fileupload.php In this example, in move_uploaded_file function, look at $target_path. That's the path. Save that in the table.
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 ....
Thanks silviuks
