[SOLVED] 2 image questions/problems

[almightyegg]

Image question 1

 

I want all my members to log on and all have the same default image called default.jpg and if they upload a new image then it is called userid.jpg (must be jpg) how would I do a search to see if there was an image called $mem[id].jpg and if there isn't show default.jpg?

 

Image question 2

 

Each member also has a main image which is set in the site as the same one, but with different colours etc. But in the site they can add things to the image eg. they click that they want a bandana and it adds it to the image.I know it's possible but I don't know whether it is in php...My limits are php html and css

 

Thanks for reading

For question 1:

 

If your storing it in a mysql database, you could simply set the image field's default value to default.jpg.

 

Otherwise I don't exactly understand how your doing your image checking.

 

For question 2:

You will need to have PHP's GD library installed.

For question one, you might consider looking at http://us2.php.net/manual/en/function.file-exists.php.

 

The first example provided might do what you need.

$file = '/images/players/a$mem[id].jpg';

if(file_exists($file)){
echo "<img src='http://www.lordoftheabyss.com/images/players/a$mem[id].jpg'>";
}else{
echo "<img src='http://www.lordoftheabyss.com/images/players/default.jpg'>";
}

 

There is a file called a1.jpg (my id is 1) and yet it still doesn't show

Thanks I'll take a look

You need to use the full path for file_exists

You might even use a boolean in the Database for default - if it's 1, show the default, if 0, they have an image - that might work easier.

[almightyegg]

I looked up boolean and it looks complicated but my script still doesn't work with the full path

[JBS103]

<?php
$file = '/images/players/a'.$mem[id].'.jpg';
?>

 

Try that. Make sure to echo your file path if you are troubleshooting. I believe the other way you had it was creating "a$mem[id].jpg", instead of replacing the ID.

[Jessica]

True. False. Not really complicated...

But I think JBS solved it

[almightyegg]

Still didn't work...is there any other errors on my code:

$file = 'http://www.lordoftheabyss.com/images/players/a$mem[id].jpg';

if(file_exists($file)){
echo "<img src='http://www.lordoftheabyss.com/images/players/a'.$mem[id].'.jpg'>";
}else{
echo "<img src='http://www.lordoftheabyss.com/images/players/default.jpg'>";
}

[Jessica]

You didn't change what JBS posted...

[almightyegg]

Oops! I'm slow

alas, no joy still though.

$file = 'http://www.lordoftheabyss.com/images/players/a'.$mem[id].'.jpg';

if(file_exists($file)){
echo "<img src='http://www.lordoftheabyss.com/images/players/a'.$mem[id].'.jpg'>";
}else{
echo "<img src='http://www.lordoftheabyss.com/images/players/default.jpg'>";
}

[Jessica]

That's a url not a path. File exists won't work with a URL, it needs the path.

[almightyegg]

is the path going to be public_html/images/players/a'.$mem[id].'.jpg?

[Jessica]

Yes, only there is probably even more to it - you know when you get an error message and it says in file.... and there's a really long path? That's the whole path.

[almightyegg]

is there any fast way to find it???

[Jessica]

try print $_SERVER['SCRIPT_FILENAME']; on the file and see what it outputs.

[JBS103]

You can force an error and get the path as Jesi said.

 

<?php
echo "Force Error"
echo "Force Error"
?>

 

Should produce something similar to...

Parse error: syntax error... in /path/path/path/path/path on line x

Cool! It works now thanks you guys another happy customer
