IMAGE ID's

portech

Can someone help me with the folloing issue

I have web page which displays a number of Images dynamically i.e. dependant on a database table.
These Images are in a sense buttons.

I need to be able to assign a unique id's to the Images so when the user clicks one of the Images the next page can capture this ID and hence determine which image has been clicked and then take an appropriate action.

can some one post a some sample code for this.

Many Thanks
TIA

Well, I'm not going to hold your hand and do it for you (as this forum does encourage self initiatives). But as for your image / ID issue, if any images in your database will only show up once in any given page, could you not have an extra column in your image table that contains unique ID? That way, in PHP, when you get an image from your database, you can also assign the ID number that comes with that image (in that row).

Again, this would work if the image being used from the database is unique to the page. If the image in question is going to be used more than once on a webpage, you could also use a class column and assign the class of your image to the corresponding class item in your table).

Just a thought.

Thanks for your reply..

Maybe the following can shed a bit more light on the issue:

The images are generated dynamically from a database and placed as image inputs on the web page, once clicked the form is re submitted with the hidden inputs being passed and using a $_POST to retrieve the value. The problem is that when the image is clicked, the hidden input used to store the value, always returns the value for the last image regardless of which one is clicked. This is due to the fact that all the inputs have the same name and hence it is believed it is being overwritten each time a new image is generated and not separately for each image but without this convention there is no way of retrieving that value.

Put something in the query string of your links:
<a href="processform.php?action=something"><img src="your.img"></a>

Then you can use a case/switch to display different stuff based on the query string:

switch ($action) {
case 'something':
// your code here
break;

case: 'somethingelse':
// your code here
break;

}
