I use such code:
$query = "SELECT introtext FROM #__content WHERE alias = '$alias'";
$db->setQuery($query);
$fullArticle = $db->loadResult();
if(!strlen(trim($fullArticle))) $fullArticle = JText::_('ERR_ARTICLE_NOT_LOADED');
Article: <p>1</p><p> </p><p>2</p>
In database: <p>1</p><p> </p><p>2</p>
But it returns: <p>1</p><p>B </p><p>2</p>
Try using the following code which is the Joomla 1.6+ database query method. Works fine for me.
$db = JFactory::getDbo();
$alias = "";
$query = $db->getQuery(true);
$query->select('introtext')
->from('#__content')
->where('alias = '.(int) $alias);
$db->setQuery($query);
$fullArticle = $db->loadResult();
Then echo it like so:
echo '<p>' . $fullArticle . '</p>';
At first I was getting an error saying that $alias was undefined so I just defined it as nothing in my code, howeevr you can change it to whatever suits your needs.

Sorry. I am very new to Joomla.
After I load data from the database like this:
$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query->select('user_id')));
$query->from($db->quoteName('#__user_profiles'));
$db->setQuery($query);
$results = $db->loadObjectList();
How to I show the results?
Try
foreach ($results as $result) {
echo $result->user_id.'<br />';
}
I'm using Joomla 2.5 and I need to retrieve the field 'avatar' for the current user.
This is the code I'm using:
$user = JFactory::getUser();
$id = $user->get('id');
$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query->select('avatar')
->from('#__discuss_users')
->where('id = $id');
$db->setQuery($query);
$results = $db->loadObjectList();
But it isn't displaying any data. I tried changing the last line to:
$results = $db->loadResult();
But it doesn't work either.
If you are using it as you posted, you won't include the actual value of $id in your query. You need to append it to the string like this:
$query->select('avatar')
->from('#__discuss_users')
->where('id = '.$id);
I am usually not using the $query->select stuff, but a plain old query. Thus, you might try to do it like this (this might not be best practice though):
$user = JFactory::getUser();
$id = $user->get('id');
$db = JFactory::getDBO();
// $query = $db->getQuery(true);
$query = "SELECT ".$db->quoteName('avatar')
." FROM ".$db->quoteName('#__discuss_users')
." WHERE ".$db->quoteName('id')
." = ".$db->quote($id).";";
// $query->select('avatar')
// ->from('#__discuss_users')
// ->where('id = $id');
$db->setQuery($query);
$results = $db->loadObjectList();
Thanks for your help. The following code works:
$user = JFactory::getUser();
$id = $user->get('id');
$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query
->select($db->quoteName('avatar'))
->from($db->quoteName('#__discuss_users'))
->where('id = '.$id);
$db->setQuery($query);
$results = $db->loadResult();
echo $results;
Am learning & executing php by working on Joomla project

Edit
Hello Lodder & Elin, it works but like this, else it's showing undefined variable notice for row on return $row line.
function getItemIdByName($Name){
$db = JFactory::getDBO();
$query = $db->getQuery(true);
$query->select('*')
->from('#__menu')
->where('id = ' . $db->quote($Name));
$db->setQuery($query);
$rows = $db->loadObjectList();
foreach ($rows as $row){
$row = $row->msg;
}
$row='';
return $row;
}
Try using the following. I have made some changes to your function and used Joomla 2.5 coding standards for the database query.
$Name = "XXXXXXXXX"; //define the name variable
function getItemIdByName($Name){
$db = JFactory::getDBO();
$query = $db->getQuery(true);
$query->select('*')
->from('#__menu')
->where('id = ' . $db->quote($Name));
$db->setQuery($query);
$rows = $db->loadObjectList();
foreach ($rows as $row){
$row = $row->msg;
}
return $row;
}
echo getItemIdByName($Name); //echo the result of the function
For your Undefined Notice, You have to modify your codes like this
$cond = '';
if($Carmodel!="") {
$cond = " and prod_id='$Carmodel' ";
}
For Trying to get property of non-object Notice : I think $row is empty that is why throws notice.Check $row
var_dump($row);
Problem :
$database->loadObject(); // This line
I'm attempting to modify a date field from my database before it gets outputted to the view, but I'm not having much luck. This code doesn't seem to work, what am I doing wrong?
function get_journal_entry($id)
{
$sql = 'SELECT * FROM journal WHERE user_id = '.$this->tank_auth->get_user_id().' AND id = '.$id;
$query = $this->db->query($sql);
$query['created'] = date("c", strtotime($query['created']));
return $query->row_array();
}
$this->db->query returns a query object, not your results. You need to modify the row after calling $query->row_array.
$query = $this->db->query($sql);
$result = $query->row_array();
$result['created'] = date("c", strtotime($result['created']));
return $result;
Another version of the code, which may work:
function get_journal_entry($id)
{
$sql = 'SELECT * FROM journal WHERE user_id = ' . intval($this->tank_auth->get_user_id()) . ' AND id = ' . intval($id);
$row = $this->db->query($sql)->row_array();
$row['created'] = date("c", strtotime($row['created']));
return $row;
}
I am getting mental on this. I have tried everything so far, for hours. Here is the task:
In a module override, I use this code:
$db =& JFactory::getDBO();
$title = "Analysen & Auswertungen Infos";
$query = "SELECT introtext FROM #__content WHERE title=\"$title\"";
$db->setQuery($query);
$result = $db->loadRow();
echo $result;
This works, but since I am getting the $title dynamically from a variable I need this to work:
$db =& JFactory::getDBO();
$title = "$linktext Infos";
$query = "SELECT introtext FROM #__content WHERE title=\"$title\"";
$db->setQuery($query);
$result = $db->loadRow();
echo $result;
I have 6 variables that populate $linktext in a foreach loop, all work except the one with the string including the "&"...
I tried htmlentities and utf8_encode and different kind (actually all combinations) of " and ' in the query... nothing worked.
Whe I use the following sql query in phpmyadmin it works:
SELECT `introtext` FROM `x999x_content` WHERE `title`="Analysen & Auswertungen Infos"
I am really puzzled over this, and right now very tired and angry...
Any help will be greatly appreciated!!!
Sometimes a good long sleep is the best you can do!
I just used strlen to check the length of $linktext (which I get from DB via a foreach loop) and found that it is longer than the visible chars. This is logical because of the & which is returned as &.
In order to use this $linktext inside a new DB query, all I needed to do was to decode the html entity:
$db =& JFactory::getDBO();
// this is the correct way of doing it
$title = html_entity_decode($linktext)." Infos";
$query = "SELECT introtext FROM #__content WHERE title=\"$title\"";
$db->setQuery($query);
$result = $db->loadRow();
or any other combi for the query (",',`,$query->select ) as pointed out in the other answers
Did you try:
$db =& JFactory::getDBO();
$title = $linktext." Infos";
$query = "SELECT `introtext` FROM `#__content` WHERE `title`='".$title."'";
$db->setQuery($query);
$result = $db->loadRow();
echo $result;
I don't know if it'll work but, I never have any problems and this is how I write my code.
Try changing this line:
$query = "SELECT introtext FROM #__content WHERE title=\"$title\"";
For this:
$query = $db->getQuery( tru );
$query->select( 'introtext' );
$query->from( '#__content' );
$query->where( 'title=' . $db->Quote( $title );
I hope it helped!
I got this working:
<?php
$servername = "";
$username = "";
$password = "";
$dbname = "";
$keyvalue='101';
$conn = new mysqli($servername, $username, $password, $dbname);
$sql = "SELECT * FROM mytable WHERE keyfield='".$keyvalue."'";
$result = $conn->query($sql);
if($result && $row = $result->fetch_assoc()) {
$fsql='DESCRIBE mytable';
$fresult = $conn->query($fsql);
if($fresult){
while($frow = $fresult->fetch_assoc()) {
$fieldname=$frow['Field'];
echo($fieldname . ' = ' . $row[$fieldname] . '<br><br>');
}
}
}else echo("Failed: " . $sql);
?>
