    please help…

  3. Hi! Good tutorial!

    I have just one question… I don't know why when i put this line of code "$row->liked_by = $row->liked_by ? explode('|', $row->liked_by) : [];" the whole program stop working, it sends me the next error message "Parse error: syntax error, unexpected '[' in /home/canifarm/public_html/Noticias/Principal/Likes/index.php on line 24"

    I've looked for that error but i can´t find the answer, could you help me?

  4. question – in your insert into articles_likes code (in like.php), how would you structure the INSERT statement if you had more variables to save? I want to save the date and time. After LIMIT 1 I added a comma and NOW() to get the date/time but it doesn't add the vote or date/time. If I remove it then it works.

  5. what if i want the user not to be assigned? 

    $_SESSION['user_id'] = (int)1;

    what i mean is if i have a login page and i want the userd id of the logged in person to be the one being processed instead of the (int)1?? HELP PLEASE

  6. I've got a problem using the SQL statement in like.php with PDO (prepare() and bindValue()). Could you give any advice on this? Do these {brackets} play any role in the SELECT statement?

  7. Thanks Alex , it works for me .
    Can you please create another video for an unlike method if an user wants to unlike an article if he changes his mind or does`nt like it any more ? 
    And it will be perfect to have a max limit of displayed users that liked an article 

  8. if anybody wants to correct the grammar, just replace where you have 'people' in the sentence with the following code;
    if($article->article_likes < 2){
    echo 'person';
    echo 'people';
