Solved – Chronoforms V5 won’t add database entry because of duplicate id – 1062 – Duplicate entry ’28’ for key ‘PRIMARY’

I had to hard code a URL and pass some parameters to a Chronoform in an article. The form submitted to a database. The form submission was taking the article ID as the form’s unique ID, so I could only submit once.

Bob Janes with Chronoforms totally fixed my issue with unsetting the varible with custom PHP.

using Join with Joomla 3 select statement

I took a while to get this right.

$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query ->select(array(‘a.id’, ‘a.name’, ‘b.user_id’, ‘b.body’))
->from($db->quoteName(‘#__users’, ‘a’))
->join(‘INNER’, $db->quoteName(‘#__user_notes’, ‘b’) . ‘ ON (‘ . $db->quoteName(‘a.id’) . ‘ = ‘ . $db->quoteName(‘b.user_id’) . ‘)’)
->where($db->quoteName(‘b.body’) . ‘ = \'<p>anx001</p> \”);$db->setQuery($query);
$results = $db->loadObjectList();echo ‘<table border=”1″ cellpadding=”5″>’;
echo ‘<tr><td>ID</td><td>NAME</td></tr>’;foreach ($results as $row) {
echo “<tr><td>{$row->id}</td><td>{$row->name}</td></tr>”;
}
echo ‘</table>’;

The double quotes on the echo in the foreach loop was necessary. If I used single quotes it didn’t display the names I was looking for.

Joomla 3 – sample query of the database

Here is a snippet of code I often need to build a database query in Joomla.

 


<?php

<?php

$db = JFactory::getDbo();
 
$query = $db->getQuery(true);

// Individual fields 
//$query->select($db->quoteName(array('firstname', 'lastname')));
 // or all fields
$query->select('*') ;

$query->from($db->quoteName('#__free_month')); 
$db->setQuery($query);   $results = $db->loadObjectList();

 echo '<ul>';

foreach ($results as $row) {

echo "<li>{$row->firstname} {$row->lastname}</li>";

}

echo '</ul>';


?>

Centering a div between a div floating left and a div floating right – Responsively

Here is what I ended up using for the CSS

<style>
#contain {
width: 100%;
padding: 0;
margin: 0;
display: table;
}
#left,
#right {
text-decoration: none;
display: table-cell;
width: 310px;
text-align: center;
background: #FF9000;
color: #FFFFFF;
padding: 2% 0;
}
#filler {
display: table-cell;
width: auto;
background: #F00;
text-align: center;
}

@media (max-width: 800px) {

#contain {
display:block;
width: 100%;
}

#left,
#right {

display: block;
width: 100%;
}

#filler {
display: block;
width: 100%;
}

}

</style>

Here is the HTML.

<div id=”contain”>
<div id=”left”>1</div>
<div id=”filler”>m</div>
<div id=”right”>2</div>
</div>

I used the following link to get this result.

Make a div / div tag a hyperlink or link

This tip is very helpful with today’s web where a lot of the graphic stuff such as drop shadows and gradients are being done through CSS.

<div onclick="location.href='newurl.html';">&nbsp;</div>

New Window:

<div onclick="window.open('newurl.html','mywindow');" style="cursor: pointer;">&nbsp;</div>

Filter Google Analytics by Geo Location such as United States Only

We run Analytics for companies that only operate in the US, so when I see 51 hits from Russia it is worthless to my customers. The answer is to filter their results so we can really understand their web traffic.

Here is how I set it up.

  1. Go into the Analytics account and click on the “Admin” tab at the top, and select “Filters” under the “View” section.
    analytics_1
  2. Click “Add Filter”.
    analytics_2
  3. Hit the “Custom” button, check “Exclude”, and the “Select Field”.
    analytics_3
  4. Scroll down and select “Country”.
    analytics_4
  5. Then type in “United States”, click “Save”.
    analytics_5

You’re done!
