Help with missing images

[bionic25]

On an auction listing page im making the user who has uploaded their listings' info can also upload a photo.

on the page "listing.php?&id=***" their listing is auto-generated from mysql. part of this auto generated info is an image. As a user can only upload one photo, and their user ID is unique, the html to display this message is:

 

../images/thumbs/$username.jpg

 

Problem:

 

If they chose not to upload a photo with the listing that ugly broken image symbol is displayed. How can i hide this or have an auto

|___________________|.jpg type file that is default outputed.

 

Thanks for any answers

The way I would be tempted to do this would be:

 

When the user signs up in your form handler, check that the image upload isn't empty, and save their image path to the database if it isnt. If it is replace their path with a default one.

 

Hope this helps?

what if you did something like this (pseudo code)

 

if(file_exists(../images/thumbs/$username.jpg)) {
  output image
}

Or use the file_exists() function to check for an image

 

if(file_exists($pathToImageFile)) {
 // display the image
 echo "<img src=''>";
}

why  is it that I always forget about the file exists function?! I have written so many work arounds where that would have sufficed.

 

Top advice, ignore my suggestion!

Thanks for the posts they are both solutions. I tried the file_exist one, which seems to fit exactly what I need.

this is the new code:

			if(file_exists("..newCar/thumbs/$username.jpg")) {
				echo "<img src=\"..newCar/thumbs/$username.jpg\">;
			}
			else{
			echo "no image";
			}

 

problem is, for some reason, when i tested it it will only output "no image" even though the file DEFINITELY exists?!

 

Im new to php so may be problem in code, any ideas??

You need to use the full path to the image rather than a relative path ie.

/var/www/html/mywebsite.com/images/imagefile.jpg

	                if(file_exists("/***/***/****/*/*/******/public_html/******/images/thumbs/$username.jpg")) {
				echo "<img src=\"..newCar/images/thumbs/$username.jpg\">";
			}
			else{
			echo "no image";
			}

 

Right, tried that ^^ but now the entire page isn't working!! I tried removing this section and it worked again?! What is wrong with this code it is confusing the hell out of me, but im sure its a code error (newbie php'er)

No code errors on the screen?

How many files are in this directory?
