[SOLVED] Odd if..elseif problem

[MishieMoo]

Okay so I have a feature on my site where people can either upload their own avatar (where I check the files and all) or enter a url for a remotely hosted avatar.  I've been trying to get it to work so that the upload script will only run if there is an uploaded file, and there is not a url entered, and vice versa for the url.  For some reason, when I have both fields filled in, it will run the query for the remote url, even though it shouldn't.

 

Here's the code with only the necessary parts shown.  I edited it down for convenience

<?php
  if (isset($_POST['submit'])){ //If the form has been submitted
		 if((isset($_POST['avatar'])) && (isset($_POST['url']))){
				echo'<div class="error">ERROR:  You must either input a url or upload a file.</div><br />'; 
				}
		 elseif((isset($_POST['avatar'])) && (!isset($_POST['url']))) {
		 //upload file code here
		}  
	elseif((isset($_POST['url'])) && (!isset($_POST['avatar']))){
		 //add a url to the database
		 }
  	else{
		 echo'<div class="error">ERROR:  You must either input a url or upload a file.</div><br />';
		 }
	}?>
<div class="contenttable"><div class="tabletop">Custom Avatar Chooser</div>
    <form method="post" action="?place=forums">
  <em>Please select your .jpg/gif/png avatar.  The maximum size is 100px by 100px and 15kb.</em><br />
  <table cellspacing="0" cellpadding="0" border="0" style="text-align:left"><tr><td>
  Upload: </td><td><input type="file" name="avatar" /></td></tr>
     <tr><td>URL:</td><td><input type="text" name="url" /></td></tr>
  <tr><td colspan="2"><input type="submit" name="submit" value="Submit"></td></tr></table>

</form></div>

try, i clean your code

if (isset($_POST['submit'])){ 
 if(isset($_POST['avatar']){
 	if(isset($_POST['url'])){
		echo'<div class="error">ERROR:  You must either input a url or upload a file.</div><br />'; 
	}elseif(!isset($_POST['url'])){
		//upload file code here
	}
 }
}
elseif(!isset($_POST['avatar'])){
if(isset($_POST['url'])){
	//add a url to the database
}
}
else{
 echo'<div class="error">ERROR:  You must either input a url or upload a file.</div><br />';
}

Nope.  It still updates to the URL and displays the success message.

Put an echo in each part to see where it's failing.

Okay for some reason it's not recognizing the fact that there's a file to be uploaded. $_POST['avatar'] isn't being set even if it's the only field that I'm entering anything in.

print_r($_POST) and see what it says. Is the field defined correctly?

 

Could try using isset($_FILES['file']) instead?

[MishieMoo]

That was it.  Duh, it's not $_POST its $_FILES.  I feel so stupid.  Thanks +
