[SOLVED] Warning: Invalid argument supplied for foreach() ?

[littlevisuals]

Hi everyone 

 

Trying to add tags to a script so i've found a script online. However every time I run the script I get the error

 

Warning: Invalid argument supplied for foreach() in /Library/WebServer/Documents/tags.php on line 2

 

Can anybody tell me what this means?

 

Im using PHP Version 5.2.5, MySQL 5.1.35 via socket

It means that the argument value being passed to the foreach loop isn't an array

Maybe your not passing an array into the foreach loop.

 

Can you show the code around the foreach loop?

Sure, here is the code I have

 

<?php
      foreach ( $articleTags as $tag ) {
   
       
   
          $resultID = @mysql_query("SELECT tag_id FROM articles_tags WHERE tag_name='$tag'") or
   
              outputMessage( "SELECT FROM articles_tags failed: " . @mysql_error($linkID) );
   
          if ( $row = mysql_fetch_array($resultID, MYSQL_ASSOC) ) {
   
       
   
              $tagID = $row['tag_id'];
   
              @mysql_query("UPDATE articles_tags SET num_articles=num_articles+1 WHERE tag_id=$tagID") or
  
                  outputMessage( "UPDATE articles_tags failed: " . @mysql_error($linkID) );
  
       
  
          } else {
  
       
  
            @mysql_query("INSERT INTO articles_tags(tag_name) VALUES ('$tag')") or
  
                  outputMessage( "INSERT INTO articles_tags failed: " . @mysql_error($linkID) );
  
              $tagID = @mysql_insert_id() or outputMessage( "mysql_insert_id() failed: " . @mysql_error($linkID) );
  
          }
  
       
  
          @mysql_query("INSERT INTO articles_tagged (tag_id, article_id) VALUES ($tagID, $articleID)") or
  
              outputMessage( "INSERT INTO articles_tagged failed: " . @mysql_error($linkID) );
  
      }
  ?>

Where do you get $articleTag from?

I followed this tutorial online

 

http://www.itnewb.com/v/Comprehensive-Guide-to-PHP-MySQL-Tag-Clouds-Includes-Demo/page4

 

I couldn't understand where $articlestags even fits into it 

 

Im going to modify it into my cms im making but thought id see if it works first.

Untill you assign an array to $articleTag this will never work.

 

Common sense is telling me that $article Tag should contain an array of tags however this fits into your system

Ok will do, thankyou so much
