I'm using Joomla and want to add an item to my update statement. My PHP isn't great and I'm having some trouble figuring out the added Joomla code. I have a field in my DB called "post_date" and when the rest of the fields are changed I want to update this field to the current date. Can someone show me how to alter the below statement to do this? The entire page code is below which contains some other other helpful info if needed.

Thanks



Want to update field post_date with current date:

function save($job) {
      $tag_var = 'tag abcd';
        $db =& $this->getDBO();
            $this->_query = "UPDATE ".$db->nameQuote('#__jobboard_jobs')."
                     SET ".$db->nameQuote('job_title')."=".$db->Quote($job->job_title)."
                     , ".$db->nameQuote('expiry_date')."='".$job->expiry_date."'
                     , ".$db->nameQuote('job_type')." =".$db->Quote($job->job_type)."
                     , ".$db->nameQuote('category')." =".$db->Quote($job->category)."
                     , ".$db->nameQuote('career_level')." =".$db->Quote($job->career_level)."
                     , ".$db->nameQuote('education')." =".$db->Quote($job->education_level)."
                     , ".$db->nameQuote('positions')." =".$db->Quote($job->positions)."
                     , ".$db->nameQuote('country')." =".$db->Quote($job->country_name)."
                     , ".$db->nameQuote('department')." =".$db->Quote($job->department)."
                     , ".$db->nameQuote('published')." =".$db->Quote($job->published)."
                     , ".$db->nameQuote('city')." =".$db->Quote($job->city)."
                     , ".$db->nameQuote('salary')." =".$db->Quote($job->salary)."
                     , ".$db->nameQuote('description')." =".$db->Quote($job->job_description)."
                     , ".$db->nameQuote('duties')." =".$db->Quote($job->duties)."
                     , ".$db->nameQuote('job_tags')." =".$db->Quote($job->job_tags)."

                 WHERE  ".$db->nameQuote('id')."=".intval($job->id);
        $db->setQuery($this->_query);
        return $db->query();
    }

I believe that you can define your table to have a DATETIME field that always, automatically contains the last updated information.

But that said, you could do something like this...

// GET THE ISO8601 DATE
$post_date = date('c');

... and add a line like this into the constructs posted above...

, ".$db->nameQuote('job_type')." =".$db->Quote($post_date)."

And my apologies for the typo above.  Change this:

, ".$db->nameQuote('job_type')." =".$db->Quote($post_date)."

into this (with the correct column name)

, ".$db->nameQuote('post_date')." =".$db->Quote($post_date)."
