PHP and Images

[stublackett]

Hi,

 

I've got images uploaded into a Database

What I'd like to know is how you use PHP to manipulate showing "No Image" or something of that sort into a web page

 

The user can add 2 images to a page, But the usual scenario is a second image doesnt get uploaded, So its leaving me with the IE [x] what I'd like to do is replace that with a possible new image

 

Is there any PHP Tutorials / Classes or anything of that sort you can point me towards to help me achieve this?

Cheers

I'm not sure what you're asking.

 

Do you want to show a 'No Image' image if there isn't one specified in the database?

[stublackett]

Thats right, Yeah!

 

A "No Image" image is what I want to display

[Xurion]

First you'll need to check if the image exists. If it does, display it, and if not, display a generic non-image.

 

if(file_exists('images/your_directory/your_image.jpg')){
    echo '<img src="images/your_directory/your_image.jpg" />';
}else{
    echo '<img src="images/your_directory/non_image.jpg" />';
}

}

Thank you Xurion

 

I suppose the same logic works for an MySQL Database and set Variables ?

Yeah, in simplest explanation - it is only an if statement.
