If statement problem

[Bman900]

Am trying to make sure that a URL ends with .png or .jpg with this code:

 

if((strrchr($avatar, '.') !== '.jpg') || (strrchr($avatar, '.') !== '.png')){
echo "That format is not valid, please select another image that is .jpg, .jpeg, .png, or .gif!";
}
else {
RUN QUERY
}

 

 

 

I also tried doing this but this doesn't work either:

 

if(!strrchr($img, '.') == '.jpg'){
echo "That format is not valid, please select another image that is .jpg, .jpeg, .png or .gif!";
} elseif(!strrchr($img, '.') == '.jpeg'){
echo "That format is not valid, please select another image that is .jpg, .jpeg, .png or .gif!";
}elseif(!strrchr($img, '.') == '.png') {
echo "That format is not valid, please select another image that is .jpg, .jpeg, .png or .gif!";
}elseif(!strrchr($img, '.') == '.gif'){
echo "That format is not valid, please select another image that is .jpg, .jpeg, .png or .gif!";
}
}
						//register
						else { 

RUN CODE }

 

 

 

 

 

No matter what I always get the error message but if I just do one check like this it works:

 

if(strrchr($avatar, '.') !== '.jpg'){
echo "That format is not valid, please select another image that is .jpg, .jpeg, .png, or .gif!";
}
else {
RUN QUERY
}

What does the URL look like?

<?php 
$url = "http://www.test.com/hello.png";
if(preg_match("/^https?:\/\/(?:[a-z\-]+\.)+[a-z]{2,6}(?:\/[^\/#?]+)+\.(?:jpg|gif|png)$/",$url))
echo "Valid";
else
echo "invalid";

?>

Thank you that works just fine. I just have to learn what you did there though.

I just used preg_match along with an if condition to Perform a regular expression match.

That nifty string within preg_match is the regex.

 

Google for more.
