How to Fetch Value from Joomla 2.5 Database Column, Field Name & Value

Question

I am trying to create a condition in which basis

Column Name Field Name Field Value

of mysql database, a conditional script should show in - Attached Table

ColumnName - FormId Fieldname - Listing Fieldvalue - Listing Value

Below is script

$max = 1;
$listing = JRequest::getInt('listing');

if($listing) {
$db = JFactory::getDBO();
$db->setQuery("SELECT COUNT(`SubmissionId`) FROM #__rsform_submission_values WHERE `FormId`='".(int) $formId."' AND `FieldName`='listing' AND `FieldValue`='".$listing."' ");
$nrSub = $db->loadResult();

if ($nrSub >= $max) {
  $formLayout = '<p>Sorry, no more submissions are accepted for this car.</p>';
}
}

I think am messing up with Fieldvalue column - may be it might not be able to fetch in value. Can someone help and advise pls

Answer 1

You are Quering count, it should be column names or * for all columns, if you need values, see example below:

$db->setQuery("SELECT * FROM #__rsform_submission_values WHERE `FormId`='".(int) $formId."' AND `FieldName`='listing' AND `FieldValue`='".$listing."' ");
$nrSub = $db->loadAssocList();
print_r($nrSub);

Additionally, Please go through with for ref Joomla DB Documentation

EDIT:

$Query = "SELECT 
    COUNT(`SubmissionId`) SubmissionCount, `FormId`, `FieldName`, `FieldValue` 
    FROM #__rsform_submission_values 
    WHERE `FormId`='".(int) $formId."' AND `FieldName`='listing' AND `FieldValue`='".$listing."'
    GROUP BY `FormId`, `FieldName`, `FieldValue`";
$db->setQuery($Query);
$nrSub = $db->loadAssocList();
print_r($nrSub);
