Displaying image regardless of extension

[perky416]

Hi everyone,

 

Sorry not sure if this is a php or html problem.

 

Im using php and a html form to upload images to my site, i have made it so that jpg, jpeg, gif and png images can be uploaded. The problem im having is displaying the image.

 

<img src="images/<?php echo $name ?>.jpg" />

 

That works fine if a jpg was uploaded, but what if a png or a gif was uploaded? The $name is going to be unique, there will not be more than one image with the same name, so what do i have to do to display the image regardless of what the extension is?

 

Thanks

When a user uploads a file you get the full name right, before you change it to something random?

 

To extract extension use the pathinfo() function:

 

$extension = pathinfo('testfile.jpg', PATHINFO_EXTENSION);

Not the complete code but this will get your extension and as you can see limit the uploads to just those extensions. This is php:

 

 

if (!empty($_FILES["image"]["name"]))

{

$image=$_FILES['image']['name'];

$filename = stripslashes($_FILES["image"]["name"]);

$extension = getExtension($filename);

$extension = strtolower($extension);

if(($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif"))

{

$hidden_text = '  Not a valid image format, only use .png, .gif, or .jpg!';

//extension is okay

}else

Hi guys,

 

Thanks but i managed to solve it shortly after posting. Like a muppet i forgot i was actually saving the URL of the image in the database, i simply recalled the url as the image SRC.

 

Thanks.
