Create a comment box in PHP and MySql for each ID

I am doing a site where people can leave comments on all the pictures I have photographed. Every photo has it’s own page; Id=1 Id=2 etc.

I would开发者_如何转开发 like a comment box where my visitors can add and see other comments already posted.

Any tips or example code would be very appreciated.

I assume you have some basic knowledge about MySQL, PHP and using MySQL with PHP. Do you already have a database table defined?

Anyway, for the comments, assuming they can be written anonymously, I would create a table comment as such:

`id` INT AUTO_INCREMENT,
`image_id` INT NOT NULL,
`content` VARCHAR(1024) NOT NULL,
`timestamp` TIMESTAMP NOT NULL DEFAULT NOW(),
PRIMARY KEY (`id`)

Create a simple form that will send you to a php page which inserts the entered data into the database.

<form name="comment" action="addcomment.php" method="post">
  <input type="hidden" id="image_id" value="$image_id" />
  <textarea id="content"></textarea>
  <input type="submit" />
</form>

The $image_id should be replaced in your php script by the ID of the image that is being commented on.

The database entry in addcomment.php should contain something similar to this:

<?php
$image_id = $_POST['image_id'];
$content = $_POST['content'];

mysql_query('INSERT INTO `comment` (`image_id`, `content`) VALUES('.$image_id.', "'.$content.'");
?>

Note: those are only bare bone hints that will both look bad and be insecure, but they should help you getting started with this...

No need to code , you can register a account on http://disqus.com and add some javascript to your site, that's all. See document on disqus.com for more information.

If you are going to put one picture per page, rather than coding why not use some blogging software like wordpress?
