Left join for multiple tables - php

Question

I am trying to execute the following MySQL query:
SELECT event.event_id, venue.venue_name, venue.alt_venue_name, venue.venue_address1, venue.cross_street, dictionary_city.city_name, venue.zip, dictionary_filter.filter_name, venue.capacity, event.start_date, event.end_date, dictionary_barType.is_ob, dictionary_barType.barType_name, event.barType_time, event.is_food, event.food_type, event.food_time, dictionary_age.age_name, dictionary_age.age_description, event.ticketCo_id, event.ticket_locator, event.ticket_left, event_description.description, event_highlight.highlight, event.event_tag, event.image_flyer, event.image_flyer_310x425, event.image_2, event.image_2_310x208, event.image_3, event.image_3_310x208
FROM event
LEFT JOIN venue
ON venue.venue_id=event.venue_id
LEFT JOIN dictionary_city
ON venue.city_id=dictionary_city.city_id
LEFT JOIN dictionary_filter
ON venue.venueType_id=dictionary_filter.filter_id
LEFT JOIN dictionary_barType
ON event.barType_id=dictionary_barType.barType_id
LEFT JOIN dictionary_age
ON event.event_age_id=dictionary_age.age_id
LEFT JOIN event_highlight
ON event_highlight.event_id=event.event_id
LEFT JOIN event_description
ON event_description.event_id=event.event_id
WHERE event.event_id="".$event_id."";
When I run the query in PhP Admin it works fine, but when I add the code to my site, I get the following error
"Warning: mysql_fetch_array() expects parameter 1 to be resource,
boolean given in
/home/nye/public_html/theballdrop.com/templates/template.event.php on
line 29 - See more at:
http://theballdrop.com/new-years-eve-madame-tussauds/#sthash.880jgbaa.dpuf"
The query it refers to is "if ($row = mysql_fetch_array($result)){"
I am not sure where to go from here. This is supposed to display information from multiple tables on a single page. $event_id is the variable and a specific event ID would determine the info to display for that specific event page.
please help.

Answer 1

Add database selection to your connect script, like so:
<?php
$hostname = "localhost";
$username = "{username]";
$password = "[pass]";
$dbname = "nye_newyears";
$con = mysql_connect("$hostname", "$username", "$password");
if (!$con) {
die('Could not connect: ' . mysql_error());
}
if(!mysql_select_db($dbname)) {
die('Could not find or access database ' . $dbname);
}
?>

Answer 2

event is a keyword in mysql. so wrap it inside quotes (`) and try.
echo your $sql in browser copy it and paste it in phpmyadmin and execute, you will get the particular error if any.

Answer 3

At first, check your MySql Table name in server. Sometimes some hosts add a prefix on table name.
You should check $result object first like
if(!$result){
exit(mysql_error());
}else{
if ($row = mysql_fetch_array($result)){
// ....
// ...
}
}

Answer 4

Thank you all for your help. Knittl you were RIGHT!!!
I added the following code to mysql-connect file:
if(!mysql_select_db($dbname)) {
die('Could not find database ' . $dbname);
}
everything works now.
Thank you so much.
